Climate Models Not in Line with Antarctic Change
13.05.2008
Scientists have found that existing computer models predicting climate change in Antarctica showed temperatures varying between 2.5 and 5 times the actual recorded temperatures. This new insight reveals that climate modelling is not fully integrating the particular climate factors present in Antarctica.
