The evidence just keeps accumulating that man's contribution to global warming is minor, at worst.
It's odd to see that one important historical fact is rarely taken into account in the global warming debate: the Earth has had numerous periods of global warming and cooling. Think about it: how could we have had "Ice Ages" without relatively warmer periods?
There is no point in handicapping ourselves and wasting trillions of dollars when we won't have a significant effect on stopping this natural cycle. And another thing: let's look at the benefits of warming as well. Focusing solely on the "apocalypse" only provides a distorted picture.
