1. GHGs, H2O, and NYC

2. Hurricanes and NYC: Why Should We Care?
IT’S HAPPENED BEFORE
Over 10 hurricanes have affected the NYC region in the past 200 years
THEY’RE GETTING STRONGER
Hurricanes will gain in intensity as warming increases
WE’RE DUE FOR ANOTHER HIT – ARE WE PREPARED?
A category 3 hurricane could cause a rise in sea levels of 1.5 feet, submerging parts of Manhattan, Brooklyn, Queens, and Staten Island

3. RISING SEA LEVELS IN NYC
Sea levels have been gradually rising
Current rate of 2.73 mm/year will be increased due to global warming
Floods in NY tremendously impact transportation system, coastal land, wetlands, beaches, and shorelines
As sea levels rise NYC will have to adapt different spheres of life
Relocating people from coastal regions
Use technology to preserve NY and prevent the disasters caused by extreme flooding

4. NYC Water Supply
Only 3% of the Worlds Water is Freshwater but only 1% is accessible, meaning most of our water is either stuck in the ground or in glaciers. So Our Available Water is VERY important!
Global Warming will cause an increase in temperature and solar radiation which in turn will cause
Decrease in water supply due to lack of precipitation and more rapid evaporation
More intense storms
Floods due to sea level rises which can lead to contamination

5. We have the power to stop it!
