The West Antarctic Ice Sheet has warmed by more than 0.1 °C (0.18 °F)/decade in the last fifty years, and the warming is the strongest in winter and spring. Although this is partly offset by fall cooling in [[East Antarctica]], this effect was restricted to the 1980s and 1990s. The continent-wide average surface temperature trend of [[Antarctica]] is positive and statistically significant at >0.05 °C (0.090 °F)/decade since 1957. This warming of WAIS is strongest in the [[Antarctic Peninsula]]. In 2012, the temperature records for the ice sheet were reanalyzed with a conclusion that since 1958, the West Antarctic ice sheet had warmed by 2.4 °C (4.3 °F), almost double the previous estimate. Some scientists now fear that the WAIS could now collapse like the [[Larsen B Ice Shelf]] did in 2002. | The West Antarctic Ice Sheet has warmed by more than 0.1 °C (0.18 °F)/decade in the last fifty years, and the warming is the strongest in winter and spring.
