•-A combination of light and heat energy from the sun reaches earth and warms the land, oceans and air, when Earth’s surface warm up, it radiates heat which rises towards the sky.
A few gases in the atmosphere called the green house gases (water vapor, carbon di-oxide, methane, ozone, nitrous etc) absorb this heat and prevent it from escaping into space thus warming earth. Green house gases keep earth warm for all living things to survive, without this warmth, earth would be about 33 degree colder than it is today, however when the level of green house gases in the atmosphere increase they trap the excess heat and make earth too hot for us to live, pollution, razing forest, burning fossil fuels and petrol increase the level of green house gases in the atmosphere and this causes global warming.
An understanding of how earth’s climate and temperature has changed in the past helps scientist to predict how and why our climate might change in the future.
It is estimated that by 2100 the average temperature will rise an additional 1.4 C to 5.8 C. Since 1880 earth has warmed up by 0.8 C in the polar region, higher sea levels, submergence of low lying islands and coastal areas. Warmer temperature has also triggered climate changes and extinction of animals and plant species. If a rise of 0.8 C can have such warming consequences what the future for making would be if we allow global warming to continue at this pace.
The Himalayan glaciers are the source of some of Asia’s biggest rivers. They provide water to one third of the world’s population. Now these glaciers are receding faster than glaciers anywhere else in the world. According to inter governmental panel on climate change (IPCC) the melting of glaciers caused by climate change could seriously affect half a billion people in the Himalaya-Hindukush region.
Warmer temperatures also increase air and water pollution therefore a 2 C rise in temperature or more will result in health problems for us. According to the World health Organization (WHO), conditions directly related to climate change cause 5 million illnesses each year.
Our everyday actions have far reaching consequences. It determines whether life on the earth will flourish or perish. One thoughtful action or a simple change in our habit will go a long way in saving our planet earth.
And air conditioner (2.5 ton) used for a house generate 3 kg of Co2. But we go without air conditioning for an hour a day, the release of 3x365=1095 kg. Co2 into atmosphere per year can be prevented.
Using a microwaves oven for an hour generate 1.3kg of Co2. If we can eat food without using our micro-woven to heat it, just for 1 hour week, we can stop the release (1.3x52)=67.6kg of Co2 into the atmosphere per year.
Compact fluorescent lamps or CFLS use one third the electricity used by regular bulbs. If every family in India replaces regular light bulbs with CFLS, 10,000 MW (a unit of power equal to one million watts of power could be saved.)
Energy used for our daily needs of electricity lower from burning fossil fuels, using less power means lower emission of green house gases into the atmosphere.
Recycling paper uses 90% less water and 50% less energy than to manufacture newspaper. It also produces 36% less Co2.
Using one liter of petrol (octane) produces about 1kg water vapor and 2.17kg of Co2.Walking carpooling or using public transport will save at least two liters of petrol a week. This will stop the release of 2.17x2x52=225.68kg of Co2 into the atmosphere annually.
The estimated population of India on March 2008 was 1.13 billion. If each person plants just one tree a life time we can estimate 1.13 billion ton of Co2 from the atmosphere. One tree absorbs one ton ofCo2 during its life time.
