I left a comment to this post on Tom's blog about how frustrating it is for a non-scientist to weigh the conflicting claims about climate change, aka global warming. Here' s the latest example where I just say "WTF?"
"Greenhouse gases could have caused an ice age, scientists claim" is confusing enough - I mean, is carbon dioxide going to cause catastrophic warming or an ice age ( or split the difference?). But then I read this sentence, which makes my head hurt - "Such glaciation could happen again if global warming is not curbed, the university's school of geography, earth and environmental sciences warned."
Wait. Wait. Global warming is going to cause an ice age?
The atmosphere getting warmer is going to cause more glaciation?
I can only conclude that one or more of those words doesn't mean what I think it means.
