New Greenland ice sheet study shows why it’s called “climate idiocy”

A new study reports that Northwest Greenland was ice free 400,000 years ago when the atmospheric CO2 level was an estimated 286 ppm. But the study authors don’t look at that finding the same way you probably do.

Here is the study media released abstract:

So I look at then result and I think: Northwest Greenland was ice-free 400,000 years ago when CO2 was at 286 ppm. Yet today Northwest Greenland is a frozen wasteland at 424 ppm CO2. That must mean that atmospheric CO2 is not determinative of whether Northwest Greenland is ice-free.

But the study authors interpret it quite differently. They need to spin readers away from that obvious conclusion.

Their bizarre take-away is essentially that we are overdue for Greenland melting because atmospheric CO2 has already increased so much past 286 ppm and all that CO2 is warming the planet.

Also note that the study authors somehow estimate it will take 30,000 years for CO2 levels to get to 380 ppm if atmospheric CO2 starts to decline by 2040. Accepting that at face value, the 350 ppm level espoused by Jim Hansen and Bill McKibben, ex of 350.org) is never happening.Not that we need this study to tell us that.

  1. Since when did cars start wafting CO2, Rog? Water vapor is produced by cars, not CO2 and it is damaging the vegans with excessive wafting!! Please stop spreading this frightful propaganda. Please!!!

  2. I read somewhere that fossilized tree stumps had been found under the Greenland icecap.
    There must have been warm periods long before the well-documented phase centered around ~900 years ago when wine was produced in the northern British Isles.
    Just think how much hotter it would have been then if a billion cars had been wafting out CO2……..ROFL

  3. we’ve been approaching an asymptotic temperature for thousands of years. If I can get link the really great drawing I’ll post it here.

    They have a death grip on the false idea that CO2 warms the planet, which is pure rubbish. There is clear evidence and data to show that the rising CO2 is due to oceanic off-gassing as they warm up from other inputs to our atmosphere. See Henry’s Law for reference. If they ever did have to admit CO2 is nothing to do with it, it would falsify all their bogus “scientific” papers and books, essentially demonstrating them as idiots and the gravy train would come to a half. If only.
