Transcript of Global warming
Hot Summers? Hot Atmosphere?
IPCC Report :Feb 2007 Temperature increase 0.760C (1895 to 1995)
Hottest Year : 2005 Max. Temp In Major cities

The effect behind Heat
Most of This RadiationIs absorbed by the Earth and warms !!
Some energy is radiated backInto space as infrared waves
Those IR waves Trapped in atmosphere And it heats up
Green House Gases Carbon Di Oxide [CO2]
Methane [CH4]
Nitrous Oxide [N2O]
Traps IR radiation Heats Atmosphere Keep Temp -> 15oC
More Green House Gas -> More Rise in Temp
The Problem
Fossil Fuels – [Petroleum]Cheaper But More CO2
Chlorofluorocarbons [CFC]Refrigerators, ACs, Centralized Cooling Systems
Meat – [Methane in Digestion of cows and goats]Large Scale Animal Farms
1750 ->280PPM 2005 ->379PPM
1750 -> 715 PPB 1990 ->1732 PPB 2005 ->1774 PPB

1945 – 230 cror 2005 – 640 cror Projected 2050 – 910 cror
Collision between civilization and earth
10000 Generations ->200 cror1 Human Life -> 200 to 900 cror
More Pressure on Earth
2005 Was Hottest year on Record. We Release 70 Million Tones of CO2 into
atmosphere every Day In 2000 It rained in Antartica The Rate of Increasing CO2 is more than
650,000 years
July 26,2005 ,Mumbai,78 cms of rain in single day
In 2004,First time in history,There was a hurricane in south atlantic
Within a Decade There will be no more glaciers in glacier national park
Polar bears are drowning At 2100, The temperature will rise 5oC.
Reduce CO2 EmissionEfficient VehiclesPublic Transportation [use of cycles]
Reduce Use of ElectricityUse Efficient EquipmentsCFL,LED etc..
Recycle Recycle Plastic, Glass,Paper..
Prevent Deforestation Prevent Fire [Wild Fire] Plant Trees Alternative Power Sources
Wind Farms, Solar PowerSolar Vehicles
Prevent Growth of Deserts
