1 A gradual increase in average global temperature. Influenced by human activities. Global Warming

3 Evidence: 1) The rate of temp increase has changed. 1906 to 2005 increase by.8°C (1.3°F) 1800 to 1900 increased by.4°C

7 CO 2 Production Worldwide USAEurope SE Asia http://cdiac.ornl.gov/

8 Reasons for an increase in CO 2 http://cdiac.ornl.gov/

10 2) Increase in CO2 (and other global warming gases) 1958 – 315 ppm (parts per million) 2007 – 383 ppm

11 Measuring Oceanic Carbon Deep and shallow water research

12 CO2 Atlantic Ocean Time Series and Moorings Sites (http://cdiac.ornl.gov/oceans/ Moorings/Atlantic.html)http://cdiac.ornl.gov/oceans/ Moorings/Atlantic.html

13 Global Ocean Monitoring Stations http://cdiac.ornl.gov/oceans/Moorings/

14 Consequences of a Warmer Earth Possibilities for serious environmental problems Melting ice and rising sea levels Changing weather patterns Human health problems Agriculture Plants and animals

15 Melting Ice and Rising Sea Levels As global temperatures increase, the polar and alpine ice caps will continue to melt, adding water to the oceans. wwfblogs.org http://theforeigner.no/pages/news/tourism-and-conservation-to-meet-in-the-arctic/

16 Changing Weather Patterns Heating the atmosphere will heat the oceans further, and change their circulation patterns May increase number of storms including hurricanes Some areas will see extreme rains, while others will experience extreme droughts http://www.nbcnews.com/id/9767275/ns/technology_and_science-science/t/do-we-need-new-way-rate- hurricanes/ cnn.com

17 Human Health Problems Heat-related deaths (an extreme threat to the very young and very old) Western US Heat Wave More allergens More mosquito-borne illnesses including malaria, encephalitis, and West Nile Virus On Long Island, more ticks mean more illness including Lyme Disease, Rocky Mountain Spotted Fever, and Ehrlichiosis komonews.com

19 Agriculture If droughts continue and become more prevalent, agriculture will suffer the most due to: Overuse of aquifers for irrigation Diseased plants Decreased crop yields thedailybeast.com

20 Plants and Animals Alter the range of plant & animal species Loss of diversity Loss of food sources Increase in invasive species noaanews.noaa.gov

21 The Future of Long Island Rising sea levels leads to coastal flooding From melting sea ice and thermal expansion of the oceans Nearly 220,000 residents live in potential flood zones (15% of the population) Suffolk County Interactive Flood Map

22 What can we do? Sunday’s People’s Climate March through the streets of New York City was a risk, writes GREG MARINOVICH.
