if all the thing going ho happen like today than it will happen but if some one say soon like in next 10-20 years i think and also wish answer will be "no" so try to clean and green this earth
Global Warming in it self, I think, is a natural cycle and we have very little control over it....It happened before our existence and it will happen again during and after we are gone...
There's an interesting show (Nova, "Dimming Sun" episode, on PBS in the U.S.: http://www.pbs.org/wgbh/nova/sun/ has full transcript) that describes evidence that global warming is already worse than predicted, except that it's being masked by high levels of water vapor in the atmosphere (caused, amazingly, by airliner contrails), which are causing less light to reach the ground to cause global warming. Sunlight intensity sensors show that there actually is less light falling on the surface of the Earth than there used to be. It gets absorbed or reflected by the water vapor. But the light that does get through is trapped, so the atmosphere warms up, but not as much as if more light were falling. What's worrisome about that to me is that plants need light. If there is less light getting through to the surface, it's good because it reduces the effect of global warming, but it could also reduce crop yields, at a time when better yields are needed more than ever.
I think the human race is the biggest threat to itself. We're doing a great job at killing each other with or without the supposed threat of global warming. My 2 cents.
