The Fifth Assessment Report from the
Intergovernmental Panel on Climate Change is the
most comprehensive and relevant analysis of our
changing climate It provides the scientific fact base
that will be used around the world to formulate
climate policies in the coming years
This document is one of a series synthesizing the most pertinent findingsof AR983093 for specific economic and business sectors It was born of the beliefthat the defence sector could make more use of AR983093 which is long andhighly technical if it were distilled into an accurate accessible timelyrelevant and readable summary
Although the information presented here is a lsquotranslationrsquo of the keycontent relevant to this sector f rom AR983093 this summary report adheresto the rigorous scientific basis of the original source material
Sincere thanks are extended to all reviewers from both the science andsecurity communities for their time effort and invaluable feedback onthis document
The basis for information presented in this overview report can be foundin the fully-referenced and peer-reviewed IPCC technical and scientificbackground reports at wwwipccch

Aboutthis Document
Rising temper983137tures
The Intergovernmental Panel on Climate Change (IPCC)Fifth Assessment Report (AR983093) concludes that climatechange is unequivocal and that human activities
particularly emissions of carbon dioxide are very likelyto be the dominant cause Changes are observed in allgeographical regions the atmosphere and oceans arewarming the extent and volume of snow and ice arediminishing sea levels are rising and weather patternsare changing
Projections
Computer models of the climate used by the IPCCindicate that changes will continue under a range ofpossible greenhouse gas emission scenarios over the 21stcentury If emissions continue to rise at the current rateimpacts by the end of this century are projected to includea global average temperature 26ndash48 degrees Celsius (degC)higher than present and sea levels 045ndash082 metreshigher than present
To prevent the most severe impacts of climate changeparties to the UN Framework Convention on Climate Change(UNFCCC) agreed a target of keeping the rise in average globaltemperature since pre-industrial times below 2degC and toconsider lowering the target to 15degC in the near future
The first instalment of AR983093 in 2013 (Working Group I onthe physical science basis of climate change) concludedthat by 2011 we had already emitted about two-thirdsof the maximum cumulative amount of carbon dioxidethat we can emit if we are to have a better than two-thirdschance of meeting the 2degC target
Imp983137ct of p983137st emissions
Even if emissions are stopped immediately temperatures willremain elevated for centuries due to the effect of greenhousegases from past human emissions already present in theatmosphere Limiting temperature rise will require substantialand sustained reductions of greenhouse gas emissions

The primary purpose of militaryforces is to maintain peace andnational security In this contextlsquopeacersquo means not just the absenceof war but the maintenance ofstable conditions that provideat minimum for peoplersquos basic
needs In this respect climatechange is a growing worldwidethreat to general peace andsecurity and as such will becomean issue of increasing significancefor the military Climate changeis best understood as a lsquothreatmultiplierrsquo exacerbating existingpressures as well as presentingnew challenges to security
The overarching impact ofclimate change on the securityenvironment stems from theadditional challenges that stateswill face in meeting the basichuman needs of a growingworld population These needsinclude food shelter cleanwater and safety In some partsof the world food and waterresources are already threatenedby climate change and this trendis projected to increase Diseasedamage to infrastructure from

ability of societies to respondparticularly in more fragile or lessdeveloped countries Many statesview current and anticipatedclimate change as contributing togeopolitical concerns
Climate change also has thepotential to increase rivalry overaccess to resources in particularregions including the Arctic andtrans-boundary river basins Thecombined impacts of resourcescarcity mass migrations andweakened governments arelikely to increase potential forarmed conflict between statesseeking to safeguard or acquirevital resources and betweenpopulations within states
Security breakdowns andconflict generally emerge fromthe interactions of multiplefactors Climate change indirectlyincreases the risk of violentconflict in the forms of civilwar inter-group violence andviolent protests by exacerbatingwell-established drivers of theseconflicts such as economic andpolitical shocks Poorly designed
adaptation and mitigationstrategies can also increase therisk of violent conflict

Imp983137cts ofClim983137te Ch983137nge
Climate change poses a threat to currentand future human security Failuresin human security almost never have asingle cause but instead emerge from theinteraction of multiple factors Climatechange is set to pose an increasinglyimportant threat by undermininglivelihoods compromising culture andidentity increasing mass migrations andchallenging the ability of states to providethe conditions necessary for a stable societyTensions arising from climate change effectson human security can have implications fornational security There is strong overlapbetween governments and the defencesector because as well as protecting nationalsecurity the military is often deployed for
support in conflict or humanitarian crises
Some climate-related impacts are alreadybeing observed such as changes inagricultural output and increases in coastalflooding People living in places affectedby conflict are particularly vulnerable toclimate change
Added to other stresses such as poverty
inequality and disease the effects ofclimate change will make sustainabledevelopment objectives such as food andlivelihood security poverty reduction healthand access to clean water more difficult toachieve for many locations systems andaffected populations In recent years manyoutbreaks of conflict have been in relativelypoor tropical andor arid countries wheresocieties lack resilience These societiesare among those likely to experience thestrongest climate change impacts
Climate change could increase risks ofviolent conflict in the form of civil warinter-group violence and violent protests byexacerbating drivers of these conflicts suchas poverty and economic hardship
Mass migrations may involve peopledriven by water and food shortagesdisease flooding drought or conflictExtreme weather events have already led tosignificant population displacement andchanges in the incidence of these eventswill amplify the challenges and risks ofsuch displacement Each degree (Celsius) ofwarming is projected to decrease renewablewater resources by at least 20 for anadditional 7 of the global populationMuch displacement is temporary witheconomic factors often determining howquickly people seek to return and rebuild
Low-income migrants can find themselves
vulnerable to climate change in their newdestinations such as in poorer and high-density parts of cities Meanwhile noteveryone will have the resources necessaryto migrate at all
The destabilising effects of climate changein developing countries could haveimplications for national security in thedeveloped world
There are direct threats to human healthfrom infectious disease and other acute(heat-related) illness Climate change mayincrease the burden of a range of healthoutcomes as it is a multiplier of existingvulnerabilities including insufficient accessto safe water and improved sanitation foodinsecurity and limited access to health careand education
In many regions food production islikely to fall with lower yields from majorcrops including wheat maize and riceClimate change is also projected to affectfood security by causing a large-scale
geographical redistribution of fishThis may increase rivalry among statesover fishing access and societies relyingon fish for subsistence are likely to bedisproportionately disadvantaged

An estimated 150 million people currentlylive in cities with perennial watershortage (ie less than 100 litres per personper day for basic human needs) Projectionssuggest that up to 1 billion urban dwellersmay have insufficient water for basic humanneeds by 2050
Climate change could shift the comparativeadvantages of cities and rural areas and differentially threaten or enhancetheir resources assets and economic baseleading to significant structural changesand impacts
The rate and intensity of natural disastersmay increase resulting in more deaths anddestruction of critical infrastructure withepidemicpandemic disease outbreakssometimes following major disasters Alarge proportion of Asiarsquos population livesin Low Elevation Coastal Zones (LECZ) thatare particularly at risk from climate changehazards including sea-level rise stormsurges and typhoons
Rising sea levels along gently slopingcoastlines can challenge the territorial limitsto the maritime jurisdiction of the statesas the distance from national baselines tothe current outer limits of the ExclusiveEconomic Zone (EEZ) will increase beyond200 nautical miles over time Changes incoastal resources may also be coupled withdecreasing food security to compoundcoastal poverty This may lead in some
cases to increased criminal activities such as
piracy illegal unreported and unregulated(IUU) fishing and human weapons anddrug trafficking
The formation of new ice-free seawaysthrough the Arctic may benefit somecountries in terms of maritime accessShipping and mineral extraction in theregion are likely to increase However thismay lead to increasing international tensionas states perceive new vulnerabilities orpursue new opportunities resulting fromthese changes in geography
Military bases and operations will bedirectly impacted by sea-level rise extremeweather events loss of Arctic sea ice andother climate impacts For many nationsconducting operations in response to climatechange could increase the cost of nationalsecurity or threaten the ability to addresstraditional threats
Temperature rise could affect theeffectiveness and efficiency of themilitary The US military suspends allphysical training and strenuous exercisewhen the Wet Bulb Globe Temperature(WBGT) exceeds 32degC One estimate suggeststhat global labour productivity will bereduced during the hottest months to 60in 2100 if GHG emissions continue to rise atthe current rate Tropical and mid-latituderegions including India northern Australiaand the Southeastern United States will beparticularly negatively affected

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage
Reloc983137ting milit983137ry inst983137ll983137tions983137nd b983137ses
Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries
Incre983137sing resilience
Strategies and actions with an emphasis on
disaster risk reduction can be pursued thatincrease climate resilience while at the same
time helping to improve human livelihoods
social and economic well-being and
responsible environmental management

The global military complex is anenergy-intensive industry and in manynations defence forces are the largestsingle consumer of fossil fuels Given
the significance of its impact on climateconditions the defence sector may comeunder significant pressure to reduce its GHGemissions ndash especially if governments enactpolicies to curb climate change in line withthe globally agreed 2degC target Howeverreducing fuel consumption may benefitoperations particularly for deployed forceswhere moving large quantities of fuel iscostly and dangerous
More efficient vehicles
Internal combustion engines and jetturbines are becoming increasingly efficientExpectations are for 40ndash70 improvementsin the fuel efficiency of light-duty vehiclesby 2035 compared to present New aircrafttypically offer a 20ndash30 improvement infuel efficiency over existing models drivenby improved engine performance weightreductions and design Further gains of 40ndash50 between 2030 and 2050 are possiblecompared with 2005 levels
Altern983137tive fuels
It may be possible to replace kerosene withbiofuels which offers direct GHG emissionreductions of +30 Shifting to electricor hydrogen-fuelled vehicles promises todramatically reduce emissions
Oper983137tion983137l improvements
Aviation carbon dioxide (CO2) emissions can
be reduced through more efficient planning
of operations including routes altitudesand speeds
Unintended consequences
Some efforts to mitigate emissions andadapt to climate change can increaseinsecurity and the risk of armed conflictWhere these efforts change the distributionof or access to resources they have thepotential to cause or aggravate conflict Forexample biofuel production can lead todisputes over land food price spikes andrioting Offering payments for ReducedEmissions from Deforestation and ForestDegradation (REDD) projects may triggerconflict over land and property rights Andsome forms of low-carbon power suchas hydropower have led to conflict overforced resettlement

Climate change has the potential to
increase the risk of conflict and insecuritybecause factors such as poverty andeconomic hardship associated with ahigher risk of violent conflict are especiallysensitive to climate change Althoughmany climate risks warrant furtherinvestigation and there is a need for morecomprehensive evidence across multiplelocations and over long durations it islikely that climate change over the 21stcentury will lead to new challenges tostates and will increasingly shape nationalsecurity policies
The effects will be unevenly distributedamong countries depending on theirgeographical setting and other factors thataffect security Economically and politicallystrong nations will be able to adapt tomoderate impacts of climate change andin so doing greatly reduce security threats(although security is at risk for vulnerablepopulations even in rich countries) On theother hand the most vulnerable nationsmay struggle to respond even to moderate
climate impacts without considerableassistance People in places with existingviolent conflict are particularly vulnerableto climate threats and the highest defencethreats are in fragile states subject tomultiple impacts of climate change
Individual studies differ in theirconclusions on whether violence has astatistically significant association withclimate but there is higher confidence that
climate variability has such an impact
As climate change progresses it is likelyto increase the variability of freshwatersupplies and agricultural yields
It is likely that the military will be taskedwith providing progressively morehumanitarian support missions havingto organise large-scale logistics supportand provide medical resources to respondto epidemic disease border securityoperations and rising tensions over naturalresources The defence sector will alsoneed to consider how it adapts or relocatesfacilities equipment and operations
Security threats from climate change willbe amplified at high levels of warmingwhich ndash if emissions continue to rise at thecurrent rate ndash will cause environmentalconditions to change faster than at any timein human history Accordingly policies thatreduce GHG emissions across all sectorsare likely to reduce the security threatsof climate change in future decades As amajor user of fossil fuels military forces
are also likely to be increasingly taskedwith reducing their own emissions whichmay bring benefits in terms of the cost andcomplexity of operations

Rising temper983137tures
The Intergovernmental Panel on Climate Change (IPCC)Fifth Assessment Report (AR983093) concludes that climatechange is unequivocal and that human activities
particularly emissions of carbon dioxide are very likelyto be the dominant cause Changes are observed in allgeographical regions the atmosphere and oceans arewarming the extent and volume of snow and ice arediminishing sea levels are rising and weather patternsare changing
Projections
Computer models of the climate used by the IPCCindicate that changes will continue under a range ofpossible greenhouse gas emission scenarios over the 21stcentury If emissions continue to rise at the current rateimpacts by the end of this century are projected to includea global average temperature 26ndash48 degrees Celsius (degC)higher than present and sea levels 045ndash082 metreshigher than present
To prevent the most severe impacts of climate changeparties to the UN Framework Convention on Climate Change(UNFCCC) agreed a target of keeping the rise in average globaltemperature since pre-industrial times below 2degC and toconsider lowering the target to 15degC in the near future
The first instalment of AR983093 in 2013 (Working Group I onthe physical science basis of climate change) concludedthat by 2011 we had already emitted about two-thirdsof the maximum cumulative amount of carbon dioxidethat we can emit if we are to have a better than two-thirdschance of meeting the 2degC target
Imp983137ct of p983137st emissions
Even if emissions are stopped immediately temperatures willremain elevated for centuries due to the effect of greenhousegases from past human emissions already present in theatmosphere Limiting temperature rise will require substantialand sustained reductions of greenhouse gas emissions

Climate change poses a threat to currentand future human security Failuresin human security almost never have asingle cause but instead emerge from theinteraction of multiple factors Climatechange is set to pose an increasinglyimportant threat by undermininglivelihoods compromising culture andidentity increasing mass migrations andchallenging the ability of states to providethe conditions necessary for a stable societyTensions arising from climate change effectson human security can have implications fornational security There is strong overlapbetween governments and the defencesector because as well as protecting nationalsecurity the military is often deployed for
support in conflict or humanitarian crises
Some climate-related impacts are alreadybeing observed such as changes inagricultural output and increases in coastalflooding People living in places affectedby conflict are particularly vulnerable toclimate change
Added to other stresses such as poverty
inequality and disease the effects ofclimate change will make sustainabledevelopment objectives such as food andlivelihood security poverty reduction healthand access to clean water more difficult toachieve for many locations systems andaffected populations In recent years manyoutbreaks of conflict have been in relativelypoor tropical andor arid countries wheresocieties lack resilience These societiesare among those likely to experience thestrongest climate change impacts
Climate change could increase risks ofviolent conflict in the form of civil warinter-group violence and violent protests byexacerbating drivers of these conflicts suchas poverty and economic hardship
Mass migrations may involve peopledriven by water and food shortagesdisease flooding drought or conflictExtreme weather events have already led tosignificant population displacement andchanges in the incidence of these eventswill amplify the challenges and risks ofsuch displacement Each degree (Celsius) ofwarming is projected to decrease renewablewater resources by at least 20 for anadditional 7 of the global populationMuch displacement is temporary witheconomic factors often determining howquickly people seek to return and rebuild
Low-income migrants can find themselves
vulnerable to climate change in their newdestinations such as in poorer and high-density parts of cities Meanwhile noteveryone will have the resources necessaryto migrate at all
The destabilising effects of climate changein developing countries could haveimplications for national security in thedeveloped world
There are direct threats to human healthfrom infectious disease and other acute(heat-related) illness Climate change mayincrease the burden of a range of healthoutcomes as it is a multiplier of existingvulnerabilities including insufficient accessto safe water and improved sanitation foodinsecurity and limited access to health careand education
In many regions food production islikely to fall with lower yields from majorcrops including wheat maize and riceClimate change is also projected to affectfood security by causing a large-scale
geographical redistribution of fishThis may increase rivalry among statesover fishing access and societies relyingon fish for subsistence are likely to bedisproportionately disadvantaged

Rising sea levels along gently slopingcoastlines can challenge the territorial limitsto the maritime jurisdiction of the statesas the distance from national baselines tothe current outer limits of the ExclusiveEconomic Zone (EEZ) will increase beyond200 nautical miles over time Changes incoastal resources may also be coupled withdecreasing food security to compoundcoastal poverty This may lead in some
cases to increased criminal activities such as
piracy illegal unreported and unregulated(IUU) fishing and human weapons anddrug trafficking
The formation of new ice-free seawaysthrough the Arctic may benefit somecountries in terms of maritime accessShipping and mineral extraction in theregion are likely to increase However thismay lead to increasing international tensionas states perceive new vulnerabilities orpursue new opportunities resulting fromthese changes in geography

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage
Reloc983137ting milit983137ry inst983137ll983137tions983137nd b983137ses
Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries
Incre983137sing resilience
Strategies and actions with an emphasis on
disaster risk reduction can be pursued thatincrease climate resilience while at the same
time helping to improve human livelihoods

P14 CLIMATE EVERYONES BUSINESS
Climate change has the potential to
increase the risk of conflict and insecuritybecause factors such as poverty andeconomic hardship associated with ahigher risk of violent conflict are especiallysensitive to climate change Althoughmany climate risks warrant furtherinvestigation and there is a need for morecomprehensive evidence across multiplelocations and over long durations it islikely that climate change over the 21stcentury will lead to new challenges tostates and will increasingly shape nationalsecurity policies
The effects will be unevenly distributedamong countries depending on theirgeographical setting and other factors thataffect security Economically and politicallystrong nations will be able to adapt tomoderate impacts of climate change andin so doing greatly reduce security threats(although security is at risk for vulnerablepopulations even in rich countries) On theother hand the most vulnerable nationsmay struggle to respond even to moderate
climate impacts without considerableassistance People in places with existingviolent conflict are particularly vulnerableto climate threats and the highest defencethreats are in fragile states subject tomultiple impacts of climate change
Individual studies differ in theirconclusions on whether violence has astatistically significant association withclimate but there is higher confidence that
climate variability has such an impact
As climate change progresses it is likelyto increase the variability of freshwatersupplies and agricultural yields
It is likely that the military will be taskedwith providing progressively morehumanitarian support missions havingto organise large-scale logistics supportand provide medical resources to respondto epidemic disease border securityoperations and rising tensions over naturalresources The defence sector will alsoneed to consider how it adapts or relocatesfacilities equipment and operations
Security threats from climate change willbe amplified at high levels of warmingwhich ndash if emissions continue to rise at thecurrent rate ndash will cause environmentalconditions to change faster than at any timein human history Accordingly policies thatreduce GHG emissions across all sectorsare likely to reduce the security threatsof climate change in future decades As amajor user of fossil fuels military forces
are also likely to be increasingly taskedwith reducing their own emissions whichmay bring benefits in terms of the cost andcomplexity of operations

Climate change poses a threat to currentand future human security Failuresin human security almost never have asingle cause but instead emerge from theinteraction of multiple factors Climatechange is set to pose an increasinglyimportant threat by undermininglivelihoods compromising culture andidentity increasing mass migrations andchallenging the ability of states to providethe conditions necessary for a stable societyTensions arising from climate change effectson human security can have implications fornational security There is strong overlapbetween governments and the defencesector because as well as protecting nationalsecurity the military is often deployed for
support in conflict or humanitarian crises
Some climate-related impacts are alreadybeing observed such as changes inagricultural output and increases in coastalflooding People living in places affectedby conflict are particularly vulnerable toclimate change
Added to other stresses such as poverty
inequality and disease the effects ofclimate change will make sustainabledevelopment objectives such as food andlivelihood security poverty reduction healthand access to clean water more difficult toachieve for many locations systems andaffected populations In recent years manyoutbreaks of conflict have been in relativelypoor tropical andor arid countries wheresocieties lack resilience These societiesare among those likely to experience thestrongest climate change impacts
Climate change could increase risks ofviolent conflict in the form of civil warinter-group violence and violent protests byexacerbating drivers of these conflicts suchas poverty and economic hardship
Mass migrations may involve peopledriven by water and food shortagesdisease flooding drought or conflictExtreme weather events have already led tosignificant population displacement andchanges in the incidence of these eventswill amplify the challenges and risks ofsuch displacement Each degree (Celsius) ofwarming is projected to decrease renewablewater resources by at least 20 for anadditional 7 of the global populationMuch displacement is temporary witheconomic factors often determining howquickly people seek to return and rebuild
Low-income migrants can find themselves
vulnerable to climate change in their newdestinations such as in poorer and high-density parts of cities Meanwhile noteveryone will have the resources necessaryto migrate at all
The destabilising effects of climate changein developing countries could haveimplications for national security in thedeveloped world
There are direct threats to human healthfrom infectious disease and other acute(heat-related) illness Climate change mayincrease the burden of a range of healthoutcomes as it is a multiplier of existingvulnerabilities including insufficient accessto safe water and improved sanitation foodinsecurity and limited access to health careand education
In many regions food production islikely to fall with lower yields from majorcrops including wheat maize and riceClimate change is also projected to affectfood security by causing a large-scale
geographical redistribution of fishThis may increase rivalry among statesover fishing access and societies relyingon fish for subsistence are likely to bedisproportionately disadvantaged

An estimated 150 million people currentlylive in cities with perennial watershortage (ie less than 100 litres per personper day for basic human needs) Projectionssuggest that up to 1 billion urban dwellersmay have insufficient water for basic humanneeds by 2050
Climate change could shift the comparativeadvantages of cities and rural areas and differentially threaten or enhancetheir resources assets and economic baseleading to significant structural changesand impacts

Rising sea levels along gently slopingcoastlines can challenge the territorial limitsto the maritime jurisdiction of the statesas the distance from national baselines tothe current outer limits of the ExclusiveEconomic Zone (EEZ) will increase beyond200 nautical miles over time Changes incoastal resources may also be coupled withdecreasing food security to compoundcoastal poverty This may lead in some
cases to increased criminal activities such as
piracy illegal unreported and unregulated(IUU) fishing and human weapons anddrug trafficking
The formation of new ice-free seawaysthrough the Arctic may benefit somecountries in terms of maritime accessShipping and mineral extraction in theregion are likely to increase However thismay lead to increasing international tensionas states perceive new vulnerabilities orpursue new opportunities resulting fromthese changes in geography
Military bases and operations will bedirectly impacted by sea-level rise extremeweather events loss of Arctic sea ice andother climate impacts For many nationsconducting operations in response to climatechange could increase the cost of nationalsecurity or threaten the ability to addresstraditional threats

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage
Reloc983137ting milit983137ry inst983137ll983137tions983137nd b983137ses
Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries

Climate change has the potential to
increase the risk of conflict and insecuritybecause factors such as poverty andeconomic hardship associated with ahigher risk of violent conflict are especiallysensitive to climate change Althoughmany climate risks warrant furtherinvestigation and there is a need for morecomprehensive evidence across multiplelocations and over long durations it islikely that climate change over the 21stcentury will lead to new challenges tostates and will increasingly shape nationalsecurity policies
The effects will be unevenly distributedamong countries depending on theirgeographical setting and other factors thataffect security Economically and politicallystrong nations will be able to adapt tomoderate impacts of climate change andin so doing greatly reduce security threats(although security is at risk for vulnerablepopulations even in rich countries) On theother hand the most vulnerable nationsmay struggle to respond even to moderate
climate impacts without considerableassistance People in places with existingviolent conflict are particularly vulnerableto climate threats and the highest defencethreats are in fragile states subject tomultiple impacts of climate change
Individual studies differ in theirconclusions on whether violence has astatistically significant association withclimate but there is higher confidence that
climate variability has such an impact
As climate change progresses it is likelyto increase the variability of freshwatersupplies and agricultural yields
It is likely that the military will be taskedwith providing progressively morehumanitarian support missions havingto organise large-scale logistics supportand provide medical resources to respondto epidemic disease border securityoperations and rising tensions over naturalresources The defence sector will alsoneed to consider how it adapts or relocatesfacilities equipment and operations
Security threats from climate change willbe amplified at high levels of warmingwhich ndash if emissions continue to rise at thecurrent rate ndash will cause environmentalconditions to change faster than at any timein human history Accordingly policies thatreduce GHG emissions across all sectorsare likely to reduce the security threatsof climate change in future decades As amajor user of fossil fuels military forces
are also likely to be increasingly taskedwith reducing their own emissions whichmay bring benefits in terms of the cost andcomplexity of operations

Climate change poses a threat to currentand future human security Failuresin human security almost never have asingle cause but instead emerge from theinteraction of multiple factors Climatechange is set to pose an increasinglyimportant threat by undermininglivelihoods compromising culture andidentity increasing mass migrations andchallenging the ability of states to providethe conditions necessary for a stable societyTensions arising from climate change effectson human security can have implications fornational security There is strong overlapbetween governments and the defencesector because as well as protecting nationalsecurity the military is often deployed for
support in conflict or humanitarian crises
Some climate-related impacts are alreadybeing observed such as changes inagricultural output and increases in coastalflooding People living in places affectedby conflict are particularly vulnerable toclimate change
Added to other stresses such as poverty
inequality and disease the effects ofclimate change will make sustainabledevelopment objectives such as food andlivelihood security poverty reduction healthand access to clean water more difficult toachieve for many locations systems andaffected populations In recent years manyoutbreaks of conflict have been in relativelypoor tropical andor arid countries wheresocieties lack resilience These societiesare among those likely to experience thestrongest climate change impacts
Climate change could increase risks ofviolent conflict in the form of civil warinter-group violence and violent protests byexacerbating drivers of these conflicts suchas poverty and economic hardship
Mass migrations may involve peopledriven by water and food shortagesdisease flooding drought or conflictExtreme weather events have already led tosignificant population displacement andchanges in the incidence of these eventswill amplify the challenges and risks ofsuch displacement Each degree (Celsius) ofwarming is projected to decrease renewablewater resources by at least 20 for anadditional 7 of the global populationMuch displacement is temporary witheconomic factors often determining howquickly people seek to return and rebuild
Low-income migrants can find themselves
vulnerable to climate change in their newdestinations such as in poorer and high-density parts of cities Meanwhile noteveryone will have the resources necessaryto migrate at all
The destabilising effects of climate changein developing countries could haveimplications for national security in thedeveloped world
There are direct threats to human healthfrom infectious disease and other acute(heat-related) illness Climate change mayincrease the burden of a range of healthoutcomes as it is a multiplier of existingvulnerabilities including insufficient accessto safe water and improved sanitation foodinsecurity and limited access to health careand education
In many regions food production islikely to fall with lower yields from majorcrops including wheat maize and riceClimate change is also projected to affectfood security by causing a large-scale
geographical redistribution of fishThis may increase rivalry among statesover fishing access and societies relyingon fish for subsistence are likely to bedisproportionately disadvantaged

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage

Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries

Climate change has the potential to
increase the risk of conflict and insecuritybecause factors such as poverty andeconomic hardship associated with ahigher risk of violent conflict are especiallysensitive to climate change Althoughmany climate risks warrant furtherinvestigation and there is a need for morecomprehensive evidence across multiplelocations and over long durations it islikely that climate change over the 21stcentury will lead to new challenges tostates and will increasingly shape nationalsecurity policies
The effects will be unevenly distributedamong countries depending on theirgeographical setting and other factors thataffect security Economically and politicallystrong nations will be able to adapt tomoderate impacts of climate change andin so doing greatly reduce security threats(although security is at risk for vulnerablepopulations even in rich countries) On theother hand the most vulnerable nationsmay struggle to respond even to moderate
climate impacts without considerableassistance People in places with existingviolent conflict are particularly vulnerableto climate threats and the highest defencethreats are in fragile states subject tomultiple impacts of climate change
Individual studies differ in theirconclusions on whether violence has astatistically significant association withclimate but there is higher confidence that
climate variability has such an impact
As climate change progresses it is likelyto increase the variability of freshwatersupplies and agricultural yields
It is likely that the military will be taskedwith providing progressively morehumanitarian support missions havingto organise large-scale logistics supportand provide medical resources to respondto epidemic disease border securityoperations and rising tensions over naturalresources The defence sector will alsoneed to consider how it adapts or relocatesfacilities equipment and operations
Security threats from climate change willbe amplified at high levels of warmingwhich ndash if emissions continue to rise at thecurrent rate ndash will cause environmentalconditions to change faster than at any timein human history Accordingly policies thatreduce GHG emissions across all sectorsare likely to reduce the security threatsof climate change in future decades As amajor user of fossil fuels military forces
are also likely to be increasingly taskedwith reducing their own emissions whichmay bring benefits in terms of the cost andcomplexity of operations

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage

Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries

Climate change has the potential to
increase the risk of conflict and insecuritybecause factors such as poverty andeconomic hardship associated with ahigher risk of violent conflict are especiallysensitive to climate change Althoughmany climate risks warrant furtherinvestigation and there is a need for morecomprehensive evidence across multiplelocations and over long durations it islikely that climate change over the 21stcentury will lead to new challenges tostates and will increasingly shape nationalsecurity policies
The effects will be unevenly distributedamong countries depending on theirgeographical setting and other factors thataffect security Economically and politicallystrong nations will be able to adapt tomoderate impacts of climate change andin so doing greatly reduce security threats(although security is at risk for vulnerablepopulations even in rich countries) On theother hand the most vulnerable nationsmay struggle to respond even to moderate
climate impacts without considerableassistance People in places with existingviolent conflict are particularly vulnerableto climate threats and the highest defencethreats are in fragile states subject tomultiple impacts of climate change
Individual studies differ in theirconclusions on whether violence has astatistically significant association withclimate but there is higher confidence that
climate variability has such an impact
As climate change progresses it is likelyto increase the variability of freshwatersupplies and agricultural yields
It is likely that the military will be taskedwith providing progressively morehumanitarian support missions havingto organise large-scale logistics supportand provide medical resources to respondto epidemic disease border securityoperations and rising tensions over naturalresources The defence sector will alsoneed to consider how it adapts or relocatesfacilities equipment and operations
Security threats from climate change willbe amplified at high levels of warmingwhich ndash if emissions continue to rise at thecurrent rate ndash will cause environmentalconditions to change faster than at any timein human history Accordingly policies thatreduce GHG emissions across all sectorsare likely to reduce the security threatsof climate change in future decades As amajor user of fossil fuels military forces

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage
Reloc983137ting milit983137ry inst983137ll983137tions983137nd b983137ses
Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries
Incre983137sing resilience
Strategies and actions with an emphasis on
disaster risk reduction can be pursued thatincrease climate resilience while at the same
time helping to improve human livelihoods
social and economic well-being and
responsible environmental management

Many adaptations to climate change that
involve the military can result in significant
co-benefits such as alleviating poverty
and enhancing development especially in
developing countries Various adaptation
interventions promote well-being and security
through the diversification of income-
generating activities adaptive migration
in agricultural and fishing communities
insurance systems and education of women
Flood prep983137redness
The benefits of protecting against increased
coastal flooding and land loss due to
submergence and erosion at the global scale
are greater than the social and economic costs
of inaction Without adaptation hundreds of
millions of people will be affected by coastal
flooding and will be displaced due to land loss
by 2100 The majority are in East Southeast
and South Asia However some low-lying
developing countries (eg Bangladesh
Vietnam) and small island states are expected
to face unavoidable land loss and annual
flooding damage
Reloc983137ting milit983137ry inst983137ll983137tions983137nd b983137ses
Numerous naval bases located in coastal areas
may need to be relocated further inland if
the coast is not protected Some may require
relocation even with coastal protection
Prep983137ring for popul983137tiondispl983137cement
Some migration flows are caused by changes
in resource availability and ecosystem
services Major extreme weather events
have in the past led to significant population
displacement and the likely increase in
extreme events will amplify the challenges
and risks of such displacement Climate
change effects of this type present chronic
and episodic challenges to state capacity and
to the fundamental welfare of populations at
a scale that raises questions of state stability
The military has the ability to provide
infrastructure immediately bringing medical
supplies lift capability and communications
to devastated regions
Prep983137ring for w983137ter insecurity
Climate change is projected to reduce both
the quantity and quality of freshwater
resources in many regions of the world
Groundwater resources will be reduced in
many regions Adaptation measures can
include water resource management projects
additional water treatment systems and
water conservation Many of these methods
are expensive and take significant amounts
of time to implement This may limit their
application in poorer countries
Incre983137sing resilience
Strategies and actions with an emphasis on
disaster risk reduction can be pursued thatincrease climate resilience while at the same
time helping to improve human livelihoods
social and economic well-being and
responsible environmental management

It may be possible to replace kerosene withbiofuels which offers direct GHG emissionreductions of +30 Shifting to electricor hydrogen-fuelled vehicles promises todramatically reduce emissions

Aviation carbon dioxide (CO2) emissions can
be reduced through more efficient planning

Unintended consequences
Some efforts to mitigate emissions andadapt to climate change can increaseinsecurity and the risk of armed conflictWhere these efforts change the distributionof or access to resources they have thepotential to cause or aggravate conflict Forexample biofuel production can lead todisputes over land food price spikes andrioting Offering payments for ReducedEmissions from Deforestation and ForestDegradation (REDD) projects may triggerconflict over land and property rights Andsome forms of low-carbon power suchas hydropower have led to conflict overforced resettlement

P14 CLIMATE EVERYONES BUSINESS
Climate change has the potential to
increase the risk of conflict and insecuritybecause factors such as poverty andeconomic hardship associated with ahigher risk of violent conflict are especiallysensitive to climate change Althoughmany climate risks warrant furtherinvestigation and there is a need for morecomprehensive evidence across multiplelocations and over long durations it islikely that climate change over the 21stcentury will lead to new challenges tostates and will increasingly shape nationalsecurity policies
The effects will be unevenly distributedamong countries depending on theirgeographical setting and other factors thataffect security Economically and politicallystrong nations will be able to adapt tomoderate impacts of climate change andin so doing greatly reduce security threats(although security is at risk for vulnerablepopulations even in rich countries) On theother hand the most vulnerable nationsmay struggle to respond even to moderate
climate impacts without considerableassistance People in places with existingviolent conflict are particularly vulnerableto climate threats and the highest defencethreats are in fragile states subject tomultiple impacts of climate change
Individual studies differ in theirconclusions on whether violence has astatistically significant association withclimate but there is higher confidence that
climate variability has such an impact
As climate change progresses it is likelyto increase the variability of freshwatersupplies and agricultural yields
It is likely that the military will be taskedwith providing progressively morehumanitarian support missions havingto organise large-scale logistics supportand provide medical resources to respondto epidemic disease border securityoperations and rising tensions over naturalresources The defence sector will alsoneed to consider how it adapts or relocatesfacilities equipment and operations
Security threats from climate change willbe amplified at high levels of warmingwhich ndash if emissions continue to rise at thecurrent rate ndash will cause environmentalconditions to change faster than at any timein human history Accordingly policies thatreduce GHG emissions across all sectorsare likely to reduce the security threatsof climate change in future decades As amajor user of fossil fuels military forces
are also likely to be increasingly taskedwith reducing their own emissions whichmay bring benefits in terms of the cost andcomplexity of operations
