There are many other examples of how warming is effecting the Earth. Although the cause is still not fully understood if the scientists think that we are the most likely, probable and obvious cause then why don’t we act.
Im sure NASA is not a corrupt organisation. They are more robust than most and hire the best scientists in the world if you dont belive them why not.

Your argument about the government doesn’t add up because Australia just voted out a guy that would sooner die than admit to AGW. Australia is already experiencing a drought that has lasted since 2000 so im sure we are well aware of the impact of warmer dryer weather and besides. What is the big deal about becoming less reliant on oil and more energy efficient.

I don't think many people contest that the Earth has warmed. Some of us just don't buy the whole man-made CO2 climate driver theory.
It is true that the Earth naturally goes through cycles of warm and cool, and always has.
But it is a fact that greenhouse gasses cause planetary warming. We cannot tell exactly how much that the current gas emissions are having on these cycles. Remember that there were none of these gas emissions a few hundred years ago. It may be that continued greenhouse gas emission will eventually heat the planet to a point that it will no longer be able to sustain human life during it's hot cycles.
That is the true danger of global warming. Frankly the planet is just too hot at the moment, and everything we can do to slow that warming down is worth doing. We can live without gas emissions. Better that we preserve the Earth as a livable planet.
I am by no means an environmental extremist, I'm only mildly interested in preserving the environment. It's just that this is an issue that is so easy to fix, the only obstacle is greed. We just have to bite the bullet and move on. Emission producing activities simply have to be phased out and become obsolete. People in those industries are going to have to find new jobs. The same way that people in the oil industry will have to move on and find new jobs when we run out of oil.
EDIT: It doesn't matter whether humans are the main cause of global warming or not! We are still a partial cause, that is not being debated, that is fact. Greenhouse gasses heat up the planet, we know that. The debate is, how much of that heating is from the gasses and how much is from natural weather cycles? The answer is: it doesn't matter. We shouldn't be contributing to warming to any degree at all, even if it's only a tiny bit.
There is no need for us to emit any more gas than what comes out of our bodies and a few other small scale occurrences. There are so, so many ways to produce energy that don't involve gas emission, if people and governments would just get off their butts and invest in them. But they won't, because they don't see it as important enough, they want to spend their money on what makes them rich or happy now, not securing their future. We should be switching to renewable fuels now, but the oil companies have too much influence to let it happen.
For those of you that don't think that the stuff that comes out of the tail pipes of cars is harmful,I have an experiment for you. Go into your garage and make sure the door is closed. Now turn on the car. Let me know if you can breath that stuff. I can't. My lungs are made for oxygen not CO2. How can you not think that the rise in CO2 levels is not manmade. We cut down the forests in Indonesia and the Amazon at an unprecedented rate plus they burn forests to clear cut. I am amazed that people don't see it. What will it take to convince others? What would be dramatic enough that even the stuanchest denier would have to admit the truth?
For those of you who think that this is just a cycle that the Earth goes through consider this. The CO2 levels have not been this high for 650,000 years. There weren't even humans around when it was that high. The Antartic was ice free then. If that melts there will be a rise of 16 feet just from the ice on land in Antartica. That continent is as big as the United States and most of it is covered by an ice sheet two miles thick.
I dont think the question is whether the earth is warming or not - it is. The question is whether it was caused by us and whether there is anything we can do to stop it. After all, there was "global warming" after the ice age a long time ago and we did nothing to create that and, if we were around then, there was nothing we could do to stop it, either. It is comforting to drive low emission cars and think you are doing something about global warming - sorry, I doubt that. That said, it is good for the planet to drive low emission cars, etc, because of the pollution. etc. .
Very few, if any, informed people deny that the Earth is Warming. The debate is over whether or not human activities have any significant impact on this warming trend and what if anything, human society should do about it.
