Speaking of climate change....something known for more than 100 years

Guest post: Nothing New Under the Sun | …and Then There's Physics

Go read this excellent post which extracts a section from a 1904 book which sets out the clear understanding that already existed then as to the role of CO2 and  water vapour in regulating the Earth's climate.

Move forward a 100 years, and politically motivated, conspiracy minded idiots with a means of communication that lets them gather a gullible following easier than ever before are still denying it is possible.

Can you tell I'm feeling cranky today?
