Climate skeptics, who to follow, believers or non-believers?

The question of climate change is driving world economies right now. Universities across the world, politicians, academicians turned politicians, entrepreneurs, businessmen, name one who is not, making use of this pertinent topic to cash money from each other. Who to believe? common people most of world people are, let's say 90 percent don't even know and understand what the fuss is all about. It is only the 10 percent who are driving the rest and making lives of 90 percent people in possible (?) danger.

I am a scientist by profession, by heart, by knowledge, and everything else. I would say that climate change is a known phenomenon, it's been happening since ages when man wasn't even present on this planet. So what's so new about this? Some people, climate skeptics, cunning climate entrepreneurs say this change is accelerated by human usage of natural resources such as hydrocarbons.

Now the question for you..if Earth is incapable of handling warmer temperatures or of supporting life, it could have done so during the cretaceous times/Jurassic times when the carbon content in the atmosphere was at the maximum. The total carbon budget is not the danger to the humans, what is fatal danger to humans is those people who are threatening the innocent people.

Any comments?
