Colagal, I thank you for doing your homework. There are several problems with some of NASA's conclusions, since I believe them to be self-serving. For example, they use the 1950-1980 as a baseline. Data from NOAA shows this to be coldest three decade period in the 20th century.

The three web sites referenced below are in order. The first is a graphic presentation of ice area anomalies at the South Pole using data provided to the University of Illinois by NASA/NOAA. This data show that the Antarctic minimum was at its highest level since satellite data has been available.

The second site is a graph showing total global sea ice area from 1985 to present. If you look at the annual anomalies, you will see total global sea ice area has not changed in that period of time. No global warming (or cooling for that matter).

The third is a link to an article in World Climate Today extracted from a report in the journal Geophysical Research Letters. This article is in understandable English. The original paper is written in scientific jargon and difficult, at best, to understand. But the source is cited in the article if you wish to read it. It shows that ice area at the South Pole is increasing. To borrow a phrase (slightly corrupted) from Sir Arthur Conan Doyle – the article questions why the ‘dog, in this case NASA, didn’t bark.’ Could it be that with the manned space program coming to a close, NASA is hunting for a reason for its existence outside of the work done by JPL and have selected ‘global warming’ as its reason?
