the thing is, there are more scientists arguing that there is no real warming-there are also quite a few scientists saying there may be warming, but it's not man-made.

There would have been no loss of thousands of acres of land, topsoil blown away, without man.
The only question regarding climate change is the extent of man's contribution, and the vast majority of respected scientists say it's plenty.
