@Sagemind: The validity of his Roberts' talk comes from the fact that the cumulative effects of human activities have a self-perpetuating momentum based on things like the methane contained in permafrost. The simple argument that we simply cannot afford to be wrong far outweighs the idea that his entire thesis must be thrown out because of a handful of appeals to popularity or "hearsay" evidence. This is not a court, or even a peer-reviewed research paper.

Ice cores reveal he annual accumulation of snow in the Arctic, Greenland and Antarctica contains isotopic markers of the temperature, so there are indeed scientific methods of measuring prehistoric temperatures.

I live between Beijing and Cupertino, CA.

I grew up in the deep South of the US. I went to schools up and down the east coast.

I have traveled to every continent but Antarctica.

I love living in Asia.

Typical liberal media! Oh sure, you'll show icebergs melting but where are all the clips of them freezing?!


I thought this was conservative media scaring us about the dangers of exploding icebergs and how we need global warming to melt them before they become a threat.

My first laugh-out-loud moment of the day, thanks.

Wilhelmina Bay eh? Well I'm fairly sure they managed a few Wilhelm screams in that short clip!

Just ice warming. It happens.>> ^therealblankman:

Global warming?

Looks like David Attenborough got there first.

The Nazis went to the Moon, not Antarctica.

anyone check her work? the only one i checked, Antarctica, was way off

No comments on this or the duped vid about how the rest of the world would feel about us claiming the Moon for ourselves?

So wrong-headed I can't hardly stand it.

Antarctica is the model to follow. Shared science. The whole world coming together for shared science.
