That is the most dumb stupid bunch of crap that I have read in my 71 years.
If the Earth warms it’s global warming. If the Earth cools it’s global warming.
Surely, something cannot have, as proof of its existence, two completely opposite things. Especially when those two things are the only things that can be or can happen.
Because that’s just plain cheating.
When the dinosaurs ran around, there wasn’t even ice at the poles. It was 5-15 degrees warmer than today. Ice ages themselves didn’t even start until 40 million years ago with the rise of the Himalayas. Thus, based on paleo-climatology, we have a long way to warm up before we’re “back to normal”.
There couldn’t have been - who would have told us?
Give them a chance. By this time next year they'll have come up with theories so mind-bogglingly cretinous and self-serving that we'll look upon the present time as a haven of sweet rationality :0)
