And the models are still wrong
The Climate models that the IPCC uses to predict what world climate will do (storms, rising sea levels, loss of hair, dogs and cats living together) has yet another flaw. Antarctic climate has cooled, not risen says a recent study of Antarctic weather.
"We can now compare computer simulations with observations of actual climate trends in Antarctica," says NCAR scientist Andrew Monaghan, the lead author of the study. "This is showing us that, over the past century, most of Antarctica has not undergone the fairly dramatic warming that has affected the rest of the globe. The challenges of studying climate in this remote environment make it difficult to say what the future holds for Antarctica's climate."
The study marks the first time that scientists have been able to compare records of the past 50 to 100 years of Antarctic climate with simulations run on computer models. Researchers have used atmospheric observations to confirm that computer models are accurately simulating climate for the other six continents. The models, which are mathematical representations of Earth's climate system, are a primary method for scientists to project future climate.
Melting of the antarctic ice shelf is part of the factor which is supposed to make the sea levels rise. Artctic sea ice won't do that (See Boyles Law). Strangely, I have to wonder if increased precipitation at high altitudes and in Antarctica would in fact cause sea levels to drop due to the acumulation of the snow and ice which does not easily shift back to the oceans.
