oh.
Know another way to know that you're being sold an ideology? They never talk about the benefits of global warming. and yes, there would be benefits. You could even argue that on balance it would be bad, but there would still be some benefits. They N-E-V-E-R discuss that. You will never see a story about that. That would tend to undermine Gaia worship so therefore it must not be allowed.
People look at Greenland now, and think the Vikings were joking when they named it. But think for a minute how Greenland would be in a period of warming.
The melting runoff from the glaciers would have keep the land along the coasts well watered throughout the growing season, which would have experienced long days of sunlight. It would have been VERY green.
