Antarctica was Much Warmer as Recently as 2.6 Million Years Ago

In the past and another blog, I wrote about how there is lots of paleontological evidence that Antarctica (as late as 2.6-2.3 million years ago) was much warmer than it is today. This becomes extremely relevant to any debate about anthropogenic climate change since its ardent believers keep harping about how greenhouse gases released by human activity will, directly and indirectly, cause the ice sheet at both poles to melt and causes sea level rises not seen in many millions of years. As readers have probably figured out by now, the biggest problem with this argument is that Antarctica was far less glaciated until the last two million years. To put it another way, that continent was much warmer over millions of years when the atmospheric CO2 was either equal to or less than current levels. And this occurred while the continents were almost at their current positions.
