SciGuy: A bad week for climate change skeptics

Eric Berger:
I am in favor of a healthy debate on climate change. Few people will honestly say the Earth isn't warming. Heck, July has been the hottest month in the Netherlands since records were first kept in 1706, and Germany is reporting the same. Humans have clearly influenced the climate before (ozone hole, anyone?), and are almost certainly doing so through greenhouse gas emissions. How much of the current warming we responsible for? That's a reasonable question. I would guess quite a bit, but the final answer isn't in.
