Somebody asked for facts. As far as sea levels rising 24 feet as Algore’s movie stated, the 1996 report of the IPCC, the U.N. science advisory group, projects a "best-value" rise by 2100 of about 50 cm (20 inches).
Antarctica contains 90% of the frozen water on the planet so the question of temp change in Antarctica is important. Average temps at the closest city to Antarctica, Punta Arenas, Chile have dropped from 6.7 degrees celsius in 1888 to 5.9 degrees Celsius in 2004. This is from CISS, NASA.

From Nature magazine, 2002. 415, pages 517-520. Article on “Antarctic climate cooling and terrestrial ecosystem response” by Doran, Priscu, Lyons et al states “From 1986 to 2000 central Antarctic valleys cooled .7deg. C per decade with serious ecosystem damage from cold”.
Journal of Climate, 2000 13 pg1674-1696 Article on “Variability and trends in Antarctic surface temps from in situ and satellite infrared measurements” said “Both satellite data and ground stations show slight cooling over last 20 years”
Science magazine, 2002 295: 476-480 Article by Joghin and Tulaczk on “Positive mass balance of the Ross Ice Streams, West Antarctica” said “Side looking radar measurements show West Antarctic ice is increasing at 26.8 gigatons/ year reversing the melting trend of the last 6000 years”
Nature, 1999 399: 429-436 Petit, Jouzel, Raynard etc. Article on “Climate and atmospheric history of the past 420,000 years from the Vostok ice core, Antarctica” said “During the last 4 interglacials, going back 420,00 years, the Earth was warmer than it is today”.
Geology magazine, 1999 27: 179-182 Article by Anderson and Andrews on “Radiocarbon constraints on ice sheet advance and retreat in the Weddell Sea, Antarctica” stated “ Less Antarctic ice has melted today than occurred during the last interglacial”.
Geophysical Research Letters, 2004 31: 10.1029 Article by Liu, Curry and Martinson on “Interpretation of recent Antarctic sea ice variability” said ”Antarctic sea ice has increased since 1979”.
Annals of Glaciology 34: 435-440 C.L. Parkinson article on “Trends in the length of the southern Ocean sea-ice season, 1979-1999” said “The greater part of Antarctica experiences a longer sea-ice season, lasting 21 days longer than it did in 1979”.
Antarctica started melting 18,000 years ago at the peak of the last ice age and is predicted to continue to melt for the next 7,000 years.
What I find interesting is how the media doesn’t talk about this side of the issue. That’s because telling people everything is gonna be fine won’t sell newspapers.
