"Are Human Beings contributing to Global warming?"

In theory, I guess man contribuets to warming every time he strikes a match or farts.
As you ask, to what extent?
I tend to go with the scientist that say it is less then 5%.
To make it less, we would have to go back to being cave people.

Here in Slovakia it has been a very warm winter, but last year it was quite cold with a lot of snow. Next year? Who knows? It all depends on what the sun wants, not Al Goreon.

***To make it less, we would have to go back to being cave people.**

That is also my contention.

It has taken the Industrial Revolution 200 years to pur us where we are now and it would certainly take much longer to go back. If ever. That is to do away with our 5%. While all the while nature is in charge of the other 95%.
