(NOAA 2008)  The most carbon dioxide (385 ppm) in 800,000 years (Prof. Thomas Blunier, Univ. of Copenhagen; Monaco Declaration 2008)
  12. 12. Temperature Measurements Warming of the climate system is UNEQUIVOCAL Top 11 warmest years on record have all occurred in the last 12 years 2006 was warmest year on record in continental ASIA 2007 was warmest year on record in INDIA 2008 eighth warmest year on record (National Climatic Data Center) . NOAA
  13. 13. What do these pollutants do? – Global Fever Greenhouse gases make the earth too hot, just like: > sleeping under a heavy blanket in the summertime > wearing a parka that is too thick Our atmospheric “blanket” or “Ozone Layer” is over 37% “thicker” than it used to be. Thicker blanket traps too much heat. Global Warming Basics
  14. 14. Weather vs. Climate “Choosing shorts or long underwear on a particular day is about weather; the ratio of shorts to long underwear in the drawer is about climate.” Charles Wohlforth ~ The Whale and the Supercomputer 20081950 Global Warming Basics

INDIA is Becomig Hotter Chapman and Walsh, 2004 In past 50 years, INDIA: Temperatures have increased 12oF overall (National Assessment Synthesis Team) Worldwide: Temperatures have increased slightly more than4oF (IPCC 2007) Global Warming BasicsGlobalWarming:TheGreatestThreat©2006DeborahL.Williams Surface Air Temperature Trends 1942-2003 Chapman and Walsh, 2004 Temperature Change o C 1970-2004 -1.0 -0.2 0.2 1.0 2.0 3.5 Changes in physical and biological systems and surface temperature 1970-2004 IPCC, 2007
  17. 17.  Snow and sea ice reflect 85-90% of sun’s energy  Ocean surface and dark soil reflect only 10-20% The Albedo Effect It’s like wearing a white shirt v. a black shirt Why has INDIA warmed the most? Increased melting of snow More of sun’s heat energy is absorbed More dark earth surface is exposed Land or water warms faster Global Warming BasicsGlobalWarming:TheGreatestThreat©2006DeborahL.Williams (ACIA 2004)
  18. 18. Other Factors: 1) Albedo effect 2) More energy goes directly into warming than into evaporation 3) Atmosphere layer is thinner in the Arctic 4) Increased heat transfer from Mountains as ice retreats 5) Alterations in atmospheric and ocean circulationACIA Graphic Why has INDIA warmed the most? Global Warming Basics (ACIA 2004)

  39. 39. Impacts in India 5. Human Impacts Photo: Environment Canada Photo: Tony Weyiouanna, Sr. Human Impacts “All of these villages have lost people on the ice. When you have a small village of 300 or 400 people, losing three or four of their senior hunters, it’s a big loss. A lot of the elders will no longer go out on the sea ice because their knowledge will not work anymore. What they’ve learned and passed on for 5,000 years is no longer functional.” Will Steger Founder, globalwarming101.org “Due to unusual ice conditions, one of our young local hunters lost his life, which has not occurred in our community in my lifetime.” Fannie Weyiouanna, Shishmaref
  40. 40. If we fail to act, and CO2 keeps rising at the current rate, then a new modeling study predicts that: If we do not Act: Worst Case Predicted Temperature Increase  Average temperatures in many parts of northern Hemispheric Countries will rise more than 25oF by 2100  Arctic tundra will decline from 8% to 1.8% of the world’s land area, and Alaska will lose almost all of its evergreen boreal forests  Extinctions and profound disruptions will ensue _ _ _ _ _ +5 +10 +15 +20 +25oF (Govindasamy and Caldeira, 2005) Impacts in India 5.

  42. 42. Ocean Acidification CO2 + H20 HCO3 - + H+ Water becomes more acidic. (ACID) Remains in the atmosphere (greenhouse gas) Dissolves in sea water CO2 CO2 “The surface ocean currently absorbs about one-fourth of the CO2 emitted to the atmosphere from human activities.” GlobalWarming:TheGreatestThreat©2006DeborahL.Williams Monaco Declaration 2008 Global Cataclysmic Concerns
  43. 43. Ocean Acidification  Since 1850, ocean pH has decreased by about 0.1 unit: a 30% increase in acidity (Royal Society 2006)  At present rate of CO2 emission, acidity predicted to increase by 0.4 units: a 3-fold increase in H ions by 2100  Carbonate ion concentrations decrease Historical and Projected pH and Dissolved CO2 pH Dissolved CO2 Lower pH = MORE ACID 1850 2000 2100 Global Cataclysmic Concerns Feely, Sabine and Fabry, 2006 Historical and Projected pH and Dissolved CO2 1850 2000 2100 Historical and Projected pH and Dissolved CO2 1850 2000 2100
  44. 44. Ocean Acidification H+ + CO3 2- HCO3 - Less Carbonate Bicarbonate Hydrogen ions combine with carbonate ions in the water to form bicarbonate. This removes carbonate ions from the water, making it more difficult for organisms to form the CaCO3 they need for their shells. Carbonate ion concentrations decrease Aragonite, critical for most shells and coral is one of two polymorphs of CaCO3 GlobalWarming:TheGreatestThreat©2006DeborahL.Williams Global Cataclysmic Concerns Ocean Acidification Network 2009 Carbonate Ca + CO3 2- CaCO3
