A paper recently published attempts to measure the relationship between ice accumulation and temperature in Antarctica for the last 31000 years.

The study is based in West Antarctica. I won’t go into the details, which were covered by WUWT here. But what was interesting were the temperature graphs included, based on ice cores.

We can see that for most of the time since the end of the ice age temperatures have been much higher than now. We can also clearly see the sharp drop coinciding with the LIA, and that temperatures were similar to now in the MWP.

We are continually told that humans are pushing the earth’s climate into unknown territory, but once again we see this is not true. As far as the Antarctic is concerned, all the evidence points to the 20thC rise in temperatures being no more than a natural recovery from the LIA.

We are also threatened with several meters of sea level rise as the Antarctic melts down. Yet the evidence of the last 10000 years shows that nothing of the sort happened, even though temperatures were much higher.

    Did anyone happen to notice that while E-Nino is blamed for “boosting” CO2 in the Antarctic to a record 400 ppm, three days earlier the Russians at Vostok reported that is was a record cold minus 80.3 degrees… June 14th?

      I thought the record coldest “evah” was set a few years ago at minus 92 or 3 and the previous was minus 89 and a bit some time before that.

      Where did this minus 80.3 “record” come from or is it simply the coldest for the beginning of the Antarctic winter ?

    Of course we all know none of that matters. The only thing that matters in Antarctica these days it seems is the western Ice shelf or any place they can possibly claim there is melting going on and they can weave dooms day scenarios from the possibility of a “collapse” with catastrophic consequences.

    Perhaps the most striking is the 2.5ºC drop in the Younger Dryas, followed by a 3ºC rise. The latter appears to have taken place at a rate of 0.03 or 0.04ºC per decade – not very different from current warming, which was 0.06C/decade in the O’Donnell reconstruction.

    Shakun and Carlson 2010 found a global drop of about 0.6C in the Younger Dryas but their results were dependent on little cooling in the Southern Hemisphere. Greenland and other areas in the NH suffered drops of 5ºC or so.

    See figure 7.

    Obviously if Antarctica did cool (and later warm) during the period, the magnitude of global changes would be greater than Shakun and Carlson estimated.

    ‘We are also threatened with several meters of sea level rise as the Antarctic melts down.’

    How much melting do you get if temperature rises from ‘minus plenty’ to ‘minus plenty, plus 2’? Not a lot I suspect.

    ‘How much melting do you get if temperature rises from ‘minus plenty’ to ‘minus plenty, plus 2’? Not a lot I suspect.’

    So long as the average temperature remain well below freezing shouldn’t higher temperatures mean more precipitation leading to more ice formation and vice versa? Snow is precipitation after all.

    I would like to know who the fool is that has been recording temps for the last 8000 years? I would have said the last 100 billion years ago that sounds more scary to me.
