Re: New information surrounding global warming
Whenever I read comments like these (and denialist comments in general) I never know whether to treat them seriously or as sarcasm.

You either know the science or you don't.
The really interesting thing is to go back in time and see what happened to the earth the last time CO2 levels reached levels like these. It wasn't pretty. Denialists can brush off notions of mass extinctions (which humans would be hard-pressed to survive) but this is precisely what happened.
Consider this about the Permian Extinction:
"While the causes of this global catastrophe are unknown, an MIT-led team of researchers has now established that the end-Permian extinction was extremely rapid, triggering massive die-outs both in the oceans and on land in less than 20,000 years — the blink of an eye in geologic time. The researchers also found that this time period coincides with a massive buildup of atmospheric carbon dioxide, which likely triggered the simultaneous collapse of species in the oceans and on land."
And consider this recent and suggestive finding:
"The Permian period was hot, hot, hot: Around 270 million years ago, air temperatures near the equator may have soared to almost 74º Celsius or 165º Fahrenheit, scientists report March 18 in Geology. That’s far hotter than anywhere on Earth today."
Sea levels, as it turns out, were not 5 feet, or 16 feet, or 25 feet, or 38 feet, or 50 or 60 or 70, but 80 to 90 feet higher than today.We're not talking about the disappearance of a few coastlines. These things actually happened and it's the very pinnacle of scientific ignorance to think they can't happen again.
As God once asked Bill Cosby, "How long can you tread water?"
At this point, the only way out of this mess is to actively reduce CO2 levels, not just passively, but comprehending this necessity just isn't here yet. But it will be. Guaranteed. No doubt about it.
