Does It really Exist?

The underlying assumption of climate change is not only paradoxical, but comically reduced to the fact that-Is civilization responsible for any climatic catastrophe? Do green house gases really exist? These questions are becoming a parody on a day to day basis.

But my question is-shouldn't common sense prevail, in just accepting the fact that the more carbon is pumped out in the form of oil,coal etc. There is no escape for it but to rest as "blanket" in the sky. Therefore obviously that will lead to a rise in temperature.

Why is it hard to believe that we are responsible in the sudden rise in temperature. We know that carbon traps , so the proportionate release of carbon from the ground is directly proportional to the increase in temperature.

Lets forget about human activity for a while. If you just analyse the amount carbon that is used as fuel in power plants and automotive industry, you will be amazed as this is the more 80% contributor to green house gases.

My basic assumption is forget about,human activity, that are endorsed to climate change, but focus on the core of radicalising the use of carbon for energy consumption. i.e. renewable energy.
