  17. 17. Greenhouse gases • Intergovernmental Panel on Climate Change (IPCC) projected that global surface temperature is likely to rise 1.1 to 6.4 °C (2.0 to 11.5 °F) by 2100 • Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. • Water vapour (H2O) • Carbon Dioxide (CO2) • Methane (CH4) • Nitrous Oxide (N2O) • Ozone (O3) • CFCs • Video

Effects of higher concentration of Greenhouse gases • Change in rain pattern • Change in agricultural yeild • Heating of the ground • Melting of ice and snow • Evaporation of water • Land slides • Climate changes / increase in Extreme climate events / change in weather pattern • Melting of polar ice caps • Increase in sea level / Rise in tides • Flooding in coastal areas • Ocean Acidification • Changes in flora and fauna • Species becoming endangered/extinct • Heavy drought • Spread of disease • Loss of habitat

  28. 28. Why is the melting of Greenland’s ice sheet that big a deal? Once the ice starts to melt at the surface, it forms lakes that empty down crevasses to the bottom of the ice. You get rivers of water underneath the ice. And the ice slides towards the ocean.”
  29. 29. How much ice is on Greenland ?
  30. 30. Global Sea Levels
  31. 31. Altimeter Record of Sea Level Rise Over Past 15 Years
  32. 32. Oceanographic information • National Oceanic and Atmospheric Administration (United States Department of Commerce) NOAA's Center for Operational Oceanographic Products and Services (CO- OPS) is the authoritative source for accurate, reliable, and timely data on tides, water levels, currents and other oceanographic information
  33. 33. • The mean sea level trend is 2.06 millimeters/year with a 95% confidence interval of +/- 0.60 mm/yr based on monthly mean sea level data from 1950 to 2008 which is equivalent to a change of 0.68 feet in 100 years. • Source : National Oceanic and Atmospheric Administration, US Govt
  34. 34. • The mean sea level trend is 0.79 millimeters/year with a 95% confidence interval of +/- 0.11 mm/yr based on monthly mean sea level data from 1878 to 2008 which is equivalent to a change of 0.26 feet in 100 years. • Source : National Oceanic and Atmospheric Administration, US Govt •
  35. 35. Mean Sea Level Trend The mean sea level trend is 1.71 millimeters/year with a 95% confidence interval of +/- 0.36 mm/yr based on monthly mean sea level data from 1939 to 2007 which is equivalent to a change of 0.56 feet in 100 years. Source : National Oceanic and Atmospheric Administration, US Govt
  36. 36. The rise in sea levels is linked to three primary factors, all induced by this ongoing global climate change: Thermal expansion of sea water: Melting of glaciers and polar ice caps: Ice loss from Greenland and West Antarctica:
  37. 37. • Consequence of sea level rise: • How high it will go ? • Some of the inundation already happened
  38. 38. Focusing on Kerala …….. • Potential impacts – Salinity intrusion into aquifers and wetlands – Sun stoke / Heat stroke – Re-occurrence of deceases once eradicated
  39. 39. What next – what we can do • Produce more fuel-efficient vehicles • Reduce vehicle use • Improve energy-efficiency in buildings • Develop carbon capture and storage processes • Increase solar power • Decrease deforestation/plant forests • Improve soil carbon management strategies
  40. 40. Measures to Minimise Greenhouse Gases • GREEN/ECO-FRIENDLY TECHNOLOGY. • ALTERNATE/RENEWABLE ENERGY. • PROPER DISPOSAL OF WASTE MATERIAL • LAND-USE CHANGE. • CARBON-SINK. • AFFORESTATION. • CONSERVATION OF FORESTS.
