As the empirical evidence keeps mounting, the climate alarmist claim of a catastrophic Antarctica ice sheet melt event from "global" warming is entirely without merit.
One, as global warming alarmist scientists are finally admitting in the scientific literature, there has been no warming since 1998. Two, the average surface temperature at Vostok, Antarctica over the last two decades is a minus 55.1C degrees - that's 55 degrees below melting temperature. (click on image to enlarge)
- The 2010 annual temperature was below both the long-term and short-term averages
- The temperature average since 1990 is significantly below the peaks of the Medieval and Roman eras, and even below those prior to the Roman peak
- For the 5,000+ year period, the linear trend (aqua line) indicates overall cooling
- The green polynomial fitted curve to the data shows temperatures heading in a warming direction over the past 1,300 years, prior to modern era consumer/industrial CO2 emissions.
It should be noted that although the two polar regions both have a lot of ice, snow and cold, they are entirely different climates. These polar extremes experience warning and cooling periods at different times and at different rates/levels of change. As a result, the historical temperature regimes, commonly referred to as the 'Roman' and the 'Medieval', happened differently at the geographical opposites.
