At the end of the same article:

But said Dr Naish, "during all those natural cycles, carbon dioxide never got above 300 parts per million. So in the last 200 years, we've had this geologically unprecedented increase in CO2 - it's 30% higher than it has been over the last several million years and it's occurred at a rate we've never seen geologically."

To understand more, the Andrill team will study exhaustively the core extracted from beneath the Ross Ice Shelf. So far, the team has drilled more than 600m and expects eventually to reach 1200m beneath the seafloor.

But already, the evidence in the sediments of what happened to the Ross Ice Shelf and the West Antarctic Ice Sheet is significant.

Dr Naish muses: "If they collapsed in the past without the present level of CO2 and the Earth was two to three degrees warmer, what's going to happen with the doubling of CO2 and potentially much higher temperatures?"

They'll collapse and then reform again?

Notice how all that speculation is in one direction: one that insures that Dr. Naish gets a lot more funding for years to come.

Mcduff, you are exhaling CO2... why do you hate mother earth?

I read this article in National Geographic a few years back that talked about a single factory in Russia that produced as much pollution as the entire country of Canada!! Hurray for socialism.

As Iowahawk put it, Mother Earth is the ultimate MILF.

Going to take a few weeks to get that book by Avery, Global Warming every 1500 years.
