Well I guess most of u knows what is global warming. There are a lot of things on the net that can help you understand that. I’ll cut that can get to the point.
Global Warming has several contributors. One of which is the green house gases on which Carbon Dioxide is the Biggest contributor. Leading Scientists say that 350PPM(Parts per million is simply a way of measuring the concentration of different gases, and means the ratio of the number of carbon dioxide molecules per million other molecules in the atmosphere) is the target we should aim at so that the planet does not face run away Climate Change. And guess what.. the amount of Carbon Dioxde in Air currently is 387 PPM.. that’s a huge way off from the upper limit envisaged. Earlier IPCC had set an upper limit of 450 PPM and 2degree rise in temperature. But that limit threatens the existence of small islands.
“If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 387ppm to at most 350ppm.”

“Even a goal of 450 parts per million, which seems so difficult today, is inadequate,” said Gore, adding we “need to toughen that goal to 350 parts per million.”

We need to act fast and act well so that we can achieve the target. All is not doomed. We can still achieve it. But for that to happen all of us have to contribute in our own small way.
