Climate models may be underestimating Antarctic warming as they are missing the feedback mechanisms that lead to greater temperature increases at the poles, something known as polar amplification, according to international research. The study used 78 ice core records to reconstruct temperatures over the past 1,000 years for seven regions of Antarctica and found direct evidence of Antarctic polar amplification. The authors say their results suggest that climate models underestimate the impact of polar amplification on both natural variability and man-made climate warming.
