et al., 2008) has been to use statistical climate field reconstruction to combine the spatialinformation from satellites with temporal data from weather stations. Among the findings is that,in the last 50 years, significant warming has occurred over most of West Antarctica, extending well beyond the Antarctic Peninsula, an area much larger than previously reported. This warming exceeds 0.1 °C/decade in the last 50 years, and is strongest in winter and spring. Although this is partly offset by fall cooling in East Antarctica, this effect is restricted to the 1980s and 1990s.
