Living on the Edge: Global Climate Change and Earth History

Overview

Is there reliable evidence of climate change?

If so give an example of a very solid piece of evidence to support that the climate is changing.

If not give an example of a very solid piece of evidence to support that the climate is not changing.

Is there reliable evidence of anthropogenic global warming?
