MORE DIVERSITIES..Churu in Rajasthan records a temperature of 50C or more on a June day.Snow fall over the Himalayas.Most parts of India receives rainfall during June to September.Tura of Meghalaya receives rainfall in a single day is equal to the total rainfall of Ten years in Jaisalmer of Rajastan.It is 19C in Tawang (Arunachal Pradesh) on the same day.Only rainfall over rest of India.Tamilnadu coast remains dry during these months.

Very low rainfall in North west Himalayas and western Rajastan which is equal to 10cm per year.MONSOON REGIME IS THE UNITY OF INDIA

Lets divide the class into five groups namely A, B, C, D and E.Collect the data of temperature and rainfall of different cities of India from web site www.allrainfallreports.com .Collect the rainfall and temperature data of your town and compare it with the data of other cities of India.Make a comparative study of temperature and rainfall data of different districts of Orissa.

CLIMATE CHANGE

Temperature increased by 0.60C in 20th century.Eleven out of twelve hottest years are within 1995 to 2006.Annual rate of increase of CO2 is 1.9ppm after 1995.Concentration of methane increased from 700ppb in 1750 to 1745ppb at present and Nitrous Oxide from 270ppb to 314ppb where as CFC increased from zero to 533ppb.Rising of temperature to 30C will lead to melting of all ice on earth surface and sea level rise upto 15 feet.Existence of large cities like Venis, Bankok, Sanghai, Kolkota and Dhaka will be in danger.SOME INTERESTING FACTSFAQ

CLIMATE CHANGE & INDIAIndia has long coast line and rise of sea level will submerge large area.A population of 7.1 million living in coastal areas will be affected.Production of crops like wheat, rice etc will decrease.The natural disasters like cyclone, floods and drought will increase in frequency as well as intensity.

WHAT CAN BE DONE???Switch off the light, fan, TV and other energy using gadgets when they are not in use. Do not use those equipments that pollute or consume more energy.create public awareness.use renewable energy resources like solar, wind, biomass etc.International conferences like Earth Summit, 1992, Kyoto protocol, Copenhegen summit, 2009 are some steps to bring consensus for crusade against Climate Change.
