Welcome Visitor:

Climate Change

A balanced look at climate change and how it is already affecting the world around us.

If the climate is changing, why is it so hard to see?  Is human activity involved?  Is it necessarily bad?  What should we expect?  These and other issues will be addressed using a wealth of instrumental and geological data.

This talk evolved from the earlier talk Global Warming: Is it Real? Is it Serious?
