remember that the term Global Warming is misleading  

Answer 2

Since the end of the ice age and we are still coming out of the ice age.  It isn't like the end of the Ice Age arrives and the next day was Hawaiian type weather, it takes thousands of years to enter it, to be in it, and thousands to get out of it.  Some are short, other were long.

But is it a problem? Or part of a natural cycle?  Since these cycles are so long, scientists cannot agree on the data.

Answer 3

There are many scientists that would answer the question when did global warming start by saying it was around 8000 years ago when people started clearing the land of trees. The constant clearing of the forests is of great concern to environmentalists. Man began clearing the land for agriculture and to build suitable housing. As the number of man has grown, more and more forests have been cleared leaving a dangerously small number of trees.
