Hurricanes and NYCWhy Should We Care?

• ITS HAPPENED BEFORE
• Over 10 hurricanes have affected the NYC region
  in the past 200 years
• THEYRE GETTING STRONGER
• Hurricanes will gain in intensity as warming
  increases
• WERE 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

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

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

We have the power to stop it!
