Greenhouse gases trap the sun's heat in the atmosphere instead of letting it escape again। This leads to a term we are all now most familiar with - climate change.Some naturally existing gases like water vapour, carbon dioxide and methane have greenhouse properties. These provide the earth with the warmth it needs.But since the industrial revolution the concentration of carbon dioxide in the atmosphere has gone up by a whopping 30 per cent, trapping more heat than necessary.
.We release these gases every time we burn petrol by running a car, burn coal or even run the AC longer than needed. Greenhouse gases can be reduced by planting trees because trees absorb these gases and while you're at it, recycle paper and save existing trees as well.
according to kyoto protocal major green house gases like..carbon di oxide,nitrous oxide,sulphur hexaflouride,hydro fluoro carbon,per fluoro carbon etc.will reduce by 2012 5.2%below the level of 1990.butinternational community totally failed in the reached on this target. now kyoto protocal will finished in the end of 2012 and a new protocal will come from 2013.so i hopeful that all major countries would understand this serious problem.
