Global warming 2010

Global warming is the increase in the average temperature of the Earth's near-surface air and the

oceans since the mid-twentieth century and its projected continuation. Global surface temperature

increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005

Increasing global temperature will cause sea levels to rise and will change the amount and pattern of

precipitation, likely including an expanse of the subtropical desert regions. Other likely effects

include Arctic shrinkage and resulting Arctic methane release, shrinkage of the Amazon

rainforest (already very damaged by deforestation from logging and farming), increases in the

intensity of extreme weather events, changes in agricultural yields, modifications of trade

routes, glacier retreat, species extinctions and changes in the ranges of disease vectors.

You may wonder what global warming and climate change are. It turns out that climate change is

pretty much the same thing as global warming. It it caused by greenhouse gases, dangerous

chemicals that leak into the air. This creates a change in climate, which is the Earth warming up. Our

over-heated planet is melting the ice in the Artic, taking away the polar bears habitat. When you grow

older, the Arctic might not even exist if the temperature continues to rise.

The average global temperature has risen by almost one degree Fahrenheit over the past century,

which has driven scientists to expect that the average global temperature will increase an additional

two to six degrees over the next hundred years. This might not sound like a big deal, but it could

change the Earth's climate like never before. Eighteen thousand years ago, around the peak of the last

ice age, the temperature was only seven degrees colder than it is today, and glaciers covered almost

all of North America!

But even a small increase in the temperature over a long time period can change the climate. When

it changes, there might be even bigger changes that our race depends on, including ocean levels and

the crop planting areas changing dramatically. If you live in a very cool climate, warmer temperatures

may invade your outside space. The changes may be good or bad, it depends what the Earth's climate

has in mind.

Climate change alters the world's ecosystems and habitats - all living things rely and are included in

these places. Many of these things depend on a delicate balance of temperature, rain fall, and soil

type. A quick change in climate could upset the fragile balance and critically endanger many living

things.

Many past climate changes occurred slowly, allowing animals and plants to adapt to their new

environment or head somewhere else. However, if future climate changes occur as quickly as some

scientists think, animals and plants may not be able to react soon enough to survive. The ocean's

ecosystems could also be affected, creating many risks to the animal population.

Greenhouse effect

The causes of the recent warming are an active field of research. The scientific consensus is that the

increase in atmospheric greenhouse gases due to human activity has caused most of the warming

observed since the start of the industrial era, and the observed warming cannot be satisfactorily

explained by natural causes alone.This attribution is clearest for the most recent 50 years, which is the

period when most of the increase in greenhouse gas concentrations took place and for which the most

complete measurements exist.

Naturally occurring greenhouse gases have a mean warming effect of about 33 °C (59 °F), without

which Earth would be uninhabitable. On Earth the major greenhouse gases are water vapor, which

causes about 36–70 percent of the greenhouse effect (not including clouds); carbon dioxide (CO2),

which causes 9–26 percent; methane (CH4), which causes 4–9 percent; and ozone, which causes 3–7

percent.

Human activity since the industrial revolution has increased the atmospheric concentration of various

greenhouse gases, leading to increased radiative forcing from CO2, methane, tropospheric ozone,

CFCs and nitrous oxide.

Another important feedback process is ice-albedo feedback. When global temperatures increase, ice

near the poles melts at an increasing rate. As the ice melts, land or open water takes its place. Both

land and open water are on average less reflective than ice, and thus absorb more solar radiation. This

4



Global warming 2010

causes more warming, which in turn causes more melting, and this cycle continues. Rapid Arctic

shrinkage is already occurring, with 2007 being the lowest ever recorded sea ice area. Some models

suggest that tipping points exist, leading to a potentially rapid collapse of sea ice cover in the Arctic.

Temperature changes

Two millennia of mean surface temperatures according to different reconstructions, each smoothed on

a decadal scale. The unsmoothed, annual value for 2004 is also plotted for reference.

Global temperatures have increased by 0.75 °C (1.35 °F) relative to the period 1860–1900, according

to the instrumental temperature record. This measured temperature increase is not significantly

affected by the urban heat island effect.Since 1979, land temperatures have increased about twice as

fast as ocean temperatures (0.25 °C per decade against 0.13 °C per decade).Temperatures in the lower

troposphere have increased between 0.12 and 0.22 °C (0.22 and 0.4 °F) per decade since 1979,

according to satellite temperature measurements. Temperature is believed to have been relatively

stable over the one or two thousand years before 1850, with possibly regional fluctuations such as the

Medieval Warm Period or the Little Ice Age.

Sea temperatures increase more slowly than those on land both because of the larger effective heat

capacity of the oceans and because the ocean can lose heat by evaporation more readily than the

land.The Northern Hemisphere has more land than the Southern Hemisphere, so it warms faster. The

Northern Hemisphere also has extensive areas of seasonal snow and sea-ice cover. More greenhouse

gases are emitted in the Northern than Southern Hemisphere, but this does not contribute to the

difference in warming because the major greenhouse gases persist long enough to mix between

hemispheres.

Global warming 2010

Based on estimates by NASA's Goddard Institute for Space Studies, 2005 was the warmest year since

reliable, widespread instrumental measurements became available in the late 1800s, exceeding the

previous record set in 1998 by a few hundredths of a degree. Estimates prepared by the World

Meteorological Organization and the Climatic Research Unit concluded that 2005 was the second

warmest year, behind 1998.

Global Warming effects

Green house gases stay can stay in the atmosphere for an amount of years ranging from decades to

hundreds and thousands of years. No matter what we do, global warming is going to have some effect

on Earth. Here are the 5 deadliest effects of global warming.

1. Polar ice caps melting

The ice caps melting is a four-pronged danger.

First, it will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today theseas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels willrise.

Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are freshwater, and when they melt they will desalinate the ocean, or in plain English - make it less salty. Thedesalinization of the gulf current will “screw up” ocean currents, which regulate temperatures. The

stream shutdown or irregularity would cool the area around north-east America and Western Europe.Luckily, that will slow some of the other effects of global warming in that area!

Third, temperature rises and changing landscapes in the artic circle will endanger several species of animals. Only the most adaptable will survive.

Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflectsunlight, much of which is reflected back into space, further cooling Earth. If the ice caps melt, theonly reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.

2. Economic consequences

Most of the effects of anthropogenic global warming won’t be good. And these effects spell one thing

for the countries of the world: economic consequences. Hurricanes cause do billions of dollars indamage, diseases cost money to treat and control and conflicts exacerbate all of these.

3. Increased probability and intensity of droughts and heat waves

Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts alsoexpected in Europe. Water is already a dangerously rare commodity in Africa, and according to theIntergovernmental Panel on Climate Change, global warming will exacerbate the conditions andcould lead to conflicts and war.

4. Warmer waters and more hurricanes

As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes.We saw in this in 2004 and 2005.

5. Spread of disease

As northern countries warm, disease carrying insects migrate north, bringing plague and disease withthem. Indeed some scientists believe that in some countries thanks to global warming, malaria has not been fully eradicated.

Causes of Global Warming

1) Carbon Dioxide from Power Plants :-

In 2002 about 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for

the purpose of electricity generation. Coal accounts for 93 percent of the emissions from the

electric utility industry

Coal emits around 1.7 times as much carbon per unit of energy when burned as does natural

gas and 1.25 times as much as oil. Natural gas gives off 50% of the carbon dioxide, the

principal greenhouse gas, released by coal and 25% less carbon dioxide than oil, for the same

8



Global warming 2010

amount of energy produced. Coal contains about 80 percent more carbon per unit of energy

than gas does, and oil contains about 40 percent more. For the typical U.S. household, a metric

ton of carbon equals about 10,000 miles of driving at 25 miles per gallon of gasoline or about

one year of home heating using a natural gas-fired furnace or about four months of electricity

from coal-fired generation.

2) Carbon Dioxide Emitted from Cars

About 33% of U.S carbon dioxide emissions comes from the burning of gasoline in internal-

combustion engines of cars and light trucks (minivans, sport utility vehicles, pick-up trucks,

and jeeps). Vehicles with poor gas mileage contribute the most to global warming. For

example, according to the E.P.A's 2000 Fuel Economy Guide, a new Dodge Durango sports

utility vehicle (with a 5.9 liter engine) that gets 12 miles per gallon in the city will emit an

estimated 800 pounds of carbon dioxide over a distance of 500 city miles. In other words for

each gallon of gas a vehicle consumes, 19.6 pounds of carbon dioxide are emitted into the air.

A new Honda Insight that gets 61 miles to the gallon will only emit about 161 pounds of

carbon dioxide over the same distance of 500 city miles. Sports utility vehicles were built for

rough terrain, off road driving in mountains and deserts. When they are used for city driving,

they are so much overkill to the environment. If one has to have a large vehicle for their

family, station wagons are an intelligent choice for city driving, especially since their price is

about half that of a sports utility. Inasmuch as SUV's have a narrow wheel base in respect to

their higher silhouette, they are four times as likely as cars to rollover in an accident.

3) Carbon Dioxide from Airplanes

The UN's Intergovernmental Panel on Climate Change estimates that aviation causes 3.5

percent of global warming, and that the figure could rise to 15 percent by 2050.

4) Carbon Dioxide from Buildings

Buildings structure account for about 12% of carbon dioxide emissions.

5) Methane

While carbon dioxide is the principal greenhouse gas, methane is second most important.

According to the IPCC, Methane is more than 20 times as

effective as CO2 at trapping heat in the atmosphere. Levels of atmospheric methane have

risen 145% in the last 100 years.Methane is derived from sources such as rice paddies, bovine

flatulence, bacteria in bogs and fossil fuel production. Most of the world’s rice, and all of the

9



Global warming 2010

rice in the United States, is grown on flooded fields. When fields are flooded, anaerobic

conditions develop and the organic matter in the soil decomposes, releasing CH4 to the

atmosphere, primarily through the rice plants.

6) Water Vapor in the Atmosphere Increasing

Water vapor is the most prevalent and most poweful greenhouse gas on the planet, but its

increasing presence is the result of warming caused by carbon dioxide, methane and other

greenhouse gases. Water vapor holds onto two-thirds of the heat trapped by all the greenhouse

gases. As the Earth heats up relative humidity is able to increase, allowing the planet's

atmosphere to hold more water vapor, causing even more warming, thus a positive feedback

scenario. Because the air is warmer, the relative humidity can be higher. There is much

scientific uncertainty as to the degree this feedback loop causes increased warming, inasmuch

as the water vapor also causes increased cloud formation, which in turn reflects heat back out

into space.

7) Nitrous oxide

Another greenhouse gas is Nitrous oxide (N2O), a colourless, non-flammable gas with a

sweetish odour, commonly known as "laughing gas", and sometimes used as an anaesthetic.

Nitrous oxide is naturally produced by oceans and rainforests. Man-made sources of nitrous

oxide include nylon and nitric acid production, the use of fertilisers in agriculture, cars with

catalytic converters and the burning of organic matter. Nitrous oxide is broken down in theatmosphere by chemical reactions that involve sunlight.

8) Deforestation

After carbon emissions caused by humans, deforestation is the second principle cause of

atmospheric carbon dioxide. (Deforestation is responsible for, by the burning and cutting of

about 34 million acres of trees each year. We are losing millions of acres of rainforests each

year, the equivalent in area to the size of Italy. The destroying of tropical forests alone is

throwing hundreds of millions of tons of carbon dioxide into the atmosphere each year. We

are also losing temperate forests. The temperate forests of the world account for an absorption

rate of 2 billion tons of carbon annually. In the temperate forests of Siberia alone, the earth is

losing 10 million acres per year.

9) City Gridlock

In 1996 according to an annual study by traffic engineers [as reported in the San Francisco

10



Global warming 2010

Chronicle December 10, 1996] from Texas A and M University, it was found that drivers in

Los Angeles and New York City alone wasted 600 million gallons of gas annually while just

sitting in traffic. The 600 million gallons of gas translates to about 7.5 million tons of carbon

dioxide in just those two cities.

10) Carbon in Atmosphere and Ocean

The atmosphere contains about 750 billion tons of carbon, while 1020 billion tons are

dissolved in the surface layers of the world's ocean.

Also:

Forests 610 billion tons of Carbon

Soils 1580 " " "

Deep Ocean 38100 " "

11) Permafrost

Permafrost is a solid structure of frozen soil, extending to depths of 2.200 feet in some areas

of the arctic and subarctic regions, containing grasses, roots, sticks, much of it dating back to30,000 years. About 25% of the land areas of the Northern Hemisphere hold permafrost,

which is defined as soil whose temperature has been 32 degrees Fahrenheit (0 degrees

Celsius) for a period of at least 2 years. Permafrost is under 85% of Alaska land surface and

much of Canada, Scandinavia and Siberia and holds about 14 per cent of the world's carbon.

The hard permafrost on which is built homes and other buildings, can, with rising

temperatures, turn into a soft material causing subsidence and damage to buildings, electric

generating stations, pipelines and other structures. Ground instability would cause erosion,

affect terrain, slopes, roads, foundations and more.

Global Warming is Inspiring Scientists to Fight for Awareness

Scientists all over the world are making predictions about the ill effects of Global warming and

connecting some of the events that have taken place in the past few decades as an alarm of global

11



Global warming 2010

warming. The effect of global warming is increasing the average temperature of the earth. A rise in

earth’s temperatures can in turn root to other alterations in the ecology, including an increasing sea

level and modifying the quantity and pattern of rainfall. These modifications may boost the

occurrence and concentration of severe climate events, such as floods, famines, heat waves, tornados,

and twisters. Other consequences may comprise of higher or lower agricultural outputs, glacier

melting, lesser summer stream flows, genus extinctions and rise in the ranges of disease vectors.

As an effect of global warming species like golden toad, harlequin frog of Costa Rica has already

become extinct. There are number of species that have a threat of disappearing soon as an effect of

global warming. As an effect of global warming various new diseases have emerged lately. These

diseases are occurring frequently due to the increase in earths average temperature since the bacteria

can survive better in elevated temperatures and even multiplies faster when the conditions are

favorable. The global warming is extending the distribution of mosquitoes due to the increase in

humidity levels and their frequent growth in warmer atmosphere. Various diseases due to ebola, hanta

and machupo virus are expected due to warmer climates. The marine life is also very sensitive to the

increase in temperatures. The effect of global warming will definitely be seen on some species in the

water. A survey was made in which the marine life reacted significantly to the changes in water

temperatures. It is expected that many species will die off or become extinct due to the increase in the

temperatures of the water,

Whereas various other species, which prefer warmer waters, will increase tremendously. Perhaps the

most disturbing changes are expected in the coral reefs that are expected to die off as an effect of

global warming. The global warming is expected to cause irreversible changes in the ecosystem and

the behavior of animals.

You Can Help Fight Global Warming

Many efforts are being made by various nations to cut down the rate of global warming. One such

effort is the Kyoto agreement that has been made between various nations to reduce the emissions of

various green house gases. Also many non profit organizations are working for the cause. Al Gore

was one of the foremost U.S. politicians to heave an alarm about the hazards of global warming. He

has produced a significantly acclaimed documentary movie called "An Inconvenient Truth," and

written a book that archives his advice that Earth is dashing toward an immensely warmer future. Al

12



Global warming 2010

Gore, the former vice president of United States has given various speeches to raise an awareness of

global warming. He has warned people about the ill effects of Global warming and its remedies.

What Is The Kyoto Accord?

The Kyoto Accord is an international treaty whereby countries agree to reduce the amount of

greenhouse gases they emit if their neighbours do likewise. It is a very complex agreement that allows

trading pollution credits. If it is cheaper to reduce emissions in country A, then country B can buy the

pollution credits, and have them count toward its own quota of reductions. Happily, the global

atmosphere does not care where the greenhouse gas reductions come from.

The current Kyoto round calls for a greenhouse gas emission reduction of 6% in Canada and 5% in

the USA.

Why Ratify The Kyoto Accord?

After millions of years of remaining constant, greenhouse gas levels, particularly CO2, started to

climb sharply at the beginning of the industrial revolution. They are now almost certainly higher than

they have been in 20 million years. This is not a natural fluctuation. It is a side effect of us humans

diligently burning the oil, coal and forests. These greenhouse gasses trap heat in the atmosphere,

much like a giant greenhouse. The heating is called global warming.

Fair targets and flexible ways of meeting them

The Kyoto Protocol requires developed countries to reduce their GHG emissions below levels

specified for each of them in the Treaty. These targets must be met within a five-year time frame

between 2008 and 2012, and add up to a total cut in GHG emissions of at least 5% against the

baseline of 1990. Review and enforcement of these commitments are carried out by United Nations-

based bodies. The Protocol places a heavier burden on developed nations under the principle of

“common but differentiated responsibilities.” This has two main reasons. Firstly, those countries can

more easily pay the cost of cutting emissions. Secondly, developed countries have historically

contributed more to the problem by emitting larger amounts of GHGs per person than in developing

countries.

13



Global warming 2010

In order to give Parties a certain degree of flexibility in meeting their emission reduction targets, the

Protocol developed three innovative mechanisms - known as Emissions Trading, Joint

Implementation and the Clean Development Mechanism (CDM). These so-called ”market-based

mechanisms” allow developed Parties to earn and trade emissions credits through projects

implemented either in other developed countries or in developing countries, which they can use

towards meeting their commitments. These mechanisms help identify lowest-cost opportunities for

reducing emissions and attract private sector participation in emission reduction efforts. Developing

nations benefit in terms of technology transfer and investment brought about through collaboration

with industrialized nations under the CDM.

What is the government doing to stop global warming?

The government is doing many things to help stop global warming. The government made a lawcalled The Clean Air Act so there is less air pollution. Global warming is making people get very bad

illnesses that could make them disabled, very sick, and sometimes even die. The Clean Air Act is

making many companies change their products to decrease these problems. Part of the law says that

you may not put a certain amount of pollutants in the air. Hairspray and some other products, like

foam cups, had this problem. Making and using these products let out too much volatile organic

compounds (VOC’s), ozone-destroying chemicals (chlorofluorocarbons (CFC’s), and related

chemicals (such as CO2) into the air. Now, almost all of these products have a label on them telling

people what this product can do to the environment and many people. By 2015 all products listed on

the Clean Air Act will have this label on them:

Almost all of the other chemicals that could be harmful will have this label on them hopefully by this

time (2015) as well.

The Clean Air Act has also made car companies change some of the things inside of the cars. Cars

pollute a lot. While cars make more than half of the world’s smog (visible pollution in the air), many

things that cars need to move and heat up make even more pollution. Some things that are inside of

cars, buses, trucks, and motorcycles, like gasoline, pollute the air when the fuel is burned. It comes

out as a chemical and when mixed in the air, forms smog. Smog is a kind of pollution that you see in

the form of a cloud. If you have ever been to California you can see a lot of smog in some places.Sometimes the smog gets so bad that you cannot see at all! Smog forms when car exhaust, pollution

from homes, and pollution from factories mixes in the air and has a chemical reaction. The sun’s heat

and light add to the reaction.

Cars, buses, and trucks are also responsible for over 50% of dangerous chemicals let into the air.

Some of these chemicals can cause cancer, birth defects, trouble breathing, brain and nerve damage,

lung injures, and burning eyes. Some of the pollutants are so harmful that they can even cause death.

Ten Personal Solutions to Global Warming

Individual choices can have an impact on global climate change. Reducing your family's heat-

trapping emissions does not mean forgoing modern conveniences; it means making smart choices andusing energy-efficient products, which may require an additional investment up front, but often pay

you back in energy savings within a couple of years.

Since Americans' per capita emissions of heat-trapping gases is 5.6 tons—more than double the

amount of western Europeans—we can all make choices that will greatly reduce our families' global

warming impact.

1. The car you drive: the most important personal climate decision.

When you buy your next car, look for the one with the best fuel economy in its class. Each

gallon of gas you use is responsible for 25 pounds of heat-trapping gases in the atmosphere.

Better gas mileage not only reduces global warming, but will also save you thousands of

dollars at the pump over the life of the vehicle. Compare the fuel economy of the cars you're

considering and look for new technologies like hybrid engines.

2. Choose clean power. More than half the electricity in the United States

comes from polluting coal-fired power plants. And power plants are the single largest source

of heat-trapping gas. None of us can live without electricity, but in some states, you can

switch to electricity companies that provide 50 to 100 percent renewable energy. (For more

information go to

3. Look for Energy Star. When it comes time to replace

appliances, look for the Energy Star label on new appliances (refrigerators, freezers,

furnaces, air conditioners, and water heaters use the most energy). These items may cost a

bit more initially, but the energy savings will pay back the extra investment within a couple

of years. Household energy savings really can make a difference: If each household in the

15

http://mollymintz.com/index.html













































Global warming 2010

United States replaced its existing appliances with the most efficient models available, we

would save $15 billion in energy costs and eliminate 175 million tons of heat-trapping

gases.

4. Unplug a freezer.

One of the quickest ways to reduce your global warming impact is to unplug the extra

refrigerator or freezer you rarely use (except when you need it for holidays and parties). This

can reduce the typical family's carbon dioxide emissions by nearly 10 percent.

5. Get a home energy audit.

Take advantage of the free home energy audits offered by many utilities. Simple measures,

such as installing a programmable thermostat to replace your old dial unit or sealing and

insulating heating and cooling ducts, can each reduce a typical family's carbon dioxide

emissions by about 5 percent.

6. Light bulbs matter.

If every household in the United States replaced one regular light bulb with an energy-

saving model, we could reduce global warming pollution by more than 90 billion pounds

over the life of the bulbs; the same as taking 6.3 million cars off the road. So, replace your

incandescent bulbs with more efficient compact fluorescents, which now come in all shapesand sizes. You'll be doing your share to cut back on heat-trapping pollution and you'll save

money on your electric bills and light bulbs.

7. Think before you drive.

If you own more than one vehicle, use the less fuel-efficient one only when you can fill it

with passengers. Driving a full minivan may be kinder to the environment than two midsize

cars. Whenever possible, join a carpool or take mass transit.

8. Buy good wood.

When buying wood products, check for labels that indicate the source of the timber.

Supporting forests that are managed in a sustainable fashion makes sense for biodiversity,

and it may make sense for the climate too. Forests that are well managed are more likely to

16



















































Global warming 2010

store carbon effectively because more trees are left standing and carbon-storing soils are less

disturbed.

9. Plant a tree.

You can also make a difference in your own backyard. Get a group in your neighborhood

together and contact your local arborist or urban forester about planting trees on private

property and public land. In addition to storing carbon, trees planted in and around urban

areas and residences can provide much-needed shade in the summer, reducing energy bills

and fossil fuel use.

10. Let policymakers know you are concerned about global warming.

Our elected officials and business leaders need to hear from concerned citizens. for the

Union of Concerned Scientists Action Network to ensure that policymakers get the timely,

accurate information they need to make informed decisions about global warming solutions.
