Global Warming Earth on fire Heated earth Alaska ice melting Climate change is the biggest environmental threat today. The impact of climate change is being visible through rise in temperature, changing monsoon pattern, melting of the glaciers, sea level rise, floods, droughts etc. Melt zone . It has therefore become extremely important for us to take on the challenge of restoring the vitality of our mother earth through extensive and realistic strategies. Unfortunately, the US Government cannot see the light. Americans account for 35% of the entire global warming. The next major chunk goes to Europe. The latest culprit is China. India has been identified as one amongst 27 countries which are most vulnerable to the impacts of global warming – accelerated sea level. (UNEP, 1989). India is taking a stand but feels that our efforts may not be sufficient unless the big three react positively and fast. As reported in Times of India issue of 6th May, 2007, we have only eight years for reversing the process of self destruction causes Global warming is caused mainly due to the increased emission of carbon dioxide gas into the atmosphere. It is emitted primarily from burning fuel like wood and fossil fuels like coal, petroleum and gas. Co2 gas prevents the heat from escaping back into the outer atmosphere. As a result the earth becomes warmer However, there are other greenhouse gases that contribute to global warming. These gases are methane, nitrous oxide, CFC’s. What can we do As ordinary citizens of the country each of us can contribute in our own little way to combat global warming and reduce the impact of climate change. It is never too late to begin 1. Plant and nurture a tree until it grows up. A single tree will absorb one ton of CO2 over its lifetime 2. Turn off Electric Devices. Simply turning off your lights, fans, computer, AC, TV, DVD player etc when you’re not using them will save you thousands of kilos of CO2 a year. Now a days, consumer electronics come with energy efficiency ratings (EER). We can purchase products which have the highest EER 3. Switch over to CFL (compact fluorescent lamps) bulbs as they consume 1/4th electricity of the normal ones. CFL lasts 10 times longer. By replacing all ordinary light bulbs with CFL’s, we can reduce India’s CO2 emission by 55 million tones annually. 4. For irrigation of your garden lawn, farm etc., use sprinklers or drip irrigation 5. Turn the tap off when you soap or shave. 6. Switch over to solar heaters. Solar energy does not release CO2 and is free of cost barring the initial expenses which get paid out in less than three years. 7. Reduce the use of paper and paper products. When forests are burned or cut down, their stored carbon is released into the atmosphere – deforestation now accounts for about 20% of CO2 emissions each year. 8. Buy recycled paper products. It takes less energy to make recycled paper and it prevents loss of forests worldwide 9. Drive less. Walk, bike, carpool or use public transport more often. You’ll save 0.45 kgs of CO2 for every mile you don’t drive. Avoiding 16 kms of driving every week would eliminate about 225 kgs of CO2 emissions a year. 10. Buy fresh foods instead of frozen. Frozen foods use 10 times more energy to produce and maintain in the frozen state 11. Avoid heavily packaged products. You can save 540 kgs of CO2 if you cut down your garbage by 10%. 12. Create awareness. We need to inform and educate whoever we come in contact with on the seriousness of climate change and exchange best practices on mitigating it. 13. The wide usage of plastic bags needs to be controlled. They can never be got rid off, except burning, which itself releases toxic fumes. 14. Promote organic farming. Nitrogenous fertilizers play an important role in increasing crop yields, but also release nitrous oxide (N2O) to the atmosphere as a result of microbial action in the soil thus contributing to emission of greenhouse gas. Conclusion Global warming can be slowed and stopped with practical actions that yield a cleaner, healthier atmosphere. The question is: will we act soon enough. It is a matter of time. Ultimately it is up to us to take action to slow down and eventually reverse global warming through everyday awareness of our energy use and attention to ways we can conserve electricity and minimize fossil fuel usage. Lets do it for our earth and for our future generation. Important world summits The Helsinki conference 1989, London conference 1990, and Copenhegen conference 1992 – to protect ozone layer and phase out CFCs. The Rio Summit 1992 – GHG emission The Kyoto Protocol – reduce greenhouse gases that cause climate change. Signed in 1997 and entered into force I 2005. 174 countries accepted. Dec. 2007, at Bali in Indonesia. 180 countries participated. Discussed road map beyond Kyoto protocol till 2012. Developed countries to reduce GHG emission by 25-40% by 2020. 2009 – climate conference at Copenhagen, Denmark. 170 countries participated.
