More CO2 = More Extreme Weather
• Scientists now link extreme weather events to carbon dioxide in the air from the burning of fossil fuels.
• More atmospheric CO2 has boosted the odds of extreme heat, extreme cold, drought, & punishing rain/snow storms….

Weather and Climate
Weather – the set of conditions at any given point in time
– today, tomorrow, this week
Climate - the average set of conditions over a period of decades
– 30 year averages
![Page 15: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/15.jpg)
• Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. • Burning of fossil fuels to for transportation is the largest source of heat-trapping pollution. Second is electricity generation
![Page 16: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/16.jpg)
Global Warming Causes the Climate to Change
• Greenhouse gases trap heat – Warming of our atmosphere causes warmer
overall temperatures
– Changes to water cycle (some more rain, some less rain)
– Warms oceans, Melts glaciers, Sea-level Rise
– Effects plant growth
• Industrial Revolution – Raised atmospheric carbon dioxide levels
from 280 parts per million to 410 parts per million in the last 150 years
![Page 17: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/17.jpg)
Measuring Carbon Dioxide
• Ice cores
• Ambient Monitoring
– Mauna Loa
collecting data since 1956

Groundwater will rise with sea level
• Groundwater rise will extend further inland than sea level rise • From 1-7ft of ground water rise is predicted at ~2 mi from the coast
• The amount of groundwater rise is not uniform and
linear with distance from the coast • Depends on
– local hydrogeology, – proximity of streams or wetlands, – distance from the coast, – groundwater pumping.
• Will impact roads, underground storage tanks, drinking water wells, landfills…

Conclusions
• Long term snow records from northern New Hampshire show significant trends largely indicating: – shorter duration of snow cover (continuous cover of
at least 1”), – shorter overall snow season (first snow is later and
last snow is earlier; including trace amounts) and – less snow depth
This supports concerns that climate change is altering winter in a region that relies on snow

Mitigation
Make our buildings and homes more efficient and utilize alternative energy
![Page 48: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/48.jpg)
Mitigation
Insulate our homes, schools and businesses
![Page 49: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/49.jpg)
Mitigation
• Use water efficiently
• Waste less food
![Page 50: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/50.jpg)
Energy Use … and the obvious
• Shut stuff off!
• Unplug stuff not in use!
• Turning off computers and monitors (and other electric items) saves energy and
reduces pollution! 20% of energy is wasted The US spends $40 billion dollars each
year on wasted energy Phantom Energy!

Adaptation is Key in Planning for Climate Change
We have four adaptation options:
1. Take no action or “business as usual” scenario

Adaptation
3. “Accommodate” using natural systems (buffers)
and alternative construction techniques

Extreme Heat
Average number of days over 90 degrees per year
Climate Change in Southern NH - CSNE
![Page 63: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/63.jpg)
Future Growing Season
The growing season is projected to lengthen by about two weeks (lower
emission scenario) or five weeks (higher emission scenario)
Hotter temperatures, reduced chilling hours, enhanced evapotranspiration, and more extreme precipitation will likely result in a decrease in crop yields.
Climate Change in Southern NH - CSNE
![Page 64: Climate Change in New Hampshire: Connecting the …Climate Change in New Hampshire: Connecting the Dots Sherry Godlewski NH Department of Environmental Services Deerfield, April 2007](https://reader030.vdocuments.us/reader030/viewer/2022040823/5e6dea8cb04e3b3a0a04eca5/html5/thumbnails/64.jpg)
Future Precipitation Annual precipitation is projected to increase 17 to 20% (both
emission scenarios) by the end of the century Increase in extreme precipitation events, results in excessive runoff, flooding, damage to critical infrastructure (buildings, roads, dams, bridges,
culverts), increased erosion & degradation of water quality

Snow Covered Days
Historically we had 105 days per year with snow cover By the end of the century (high emissions scenario),
we could have only 52 days

Exacerbating Issues
• Population increase – Climate refugees
• Development increases – more pavement
• Old infrastructure - undersized • More homes built in risky
areas • Federal funding decreases • Political climate • Other?

Already Adapting - “Yankee Ingenuity”
• Power companies trimming trees and limbs
• Maintaining & upgrading culverts when replacing
• On-going road/drainage
maintenance
• Ski areas have alpine slides, canopy tours & mountain biking
• Backup generators

Investments in Adaptation
It’s not a question of IF we’ll pay to adapt
It’s a question of WHEN we’ll pay
We can plan ahead & get where we want to go
Anticipatory Adaptation
We can incur damages, clean up the mess & live with the consequences
Reactionary Adaptation
River & Stream buffers
Help to Decrease : • storm water runoff • erosion • flooding

Connecting the Dots
• Climate change will cost taxpayers more than a half a trillion dollars this decade, and trillions more in the future unless we mitigate the impacts (Government Accountability Office)
• We cannot ignore the impact of climate change on our public health, our environment, and our economy.
• The lessons will continue to be taught until they are learned.
• We’ve got to connect the dots!
