Antarctic continent has cooled from 1966 to 2000


I thought global warmers were claiming the poles should get warmer from Global Warming. But the real data shows the South P[ole has gotten colder. Why no news on this?

Climate models generally predict amplified warming in polar regions3, 4, as observed in Antarctica’s peninsula region over the second half of the 20th century5, 6, 7, 8, 9. Although previous reports suggest slight recent continental warming9, 10, our spatial analysis of Antarctic meteorological data demonstrates a net cooling on the Antarctic continent between 1966 and 2000, particularly during summer and autumn. The McMurdo Dry Valleys have cooled by 0.7 °C per decade between 1986 and 2000, with similar pronounced seasonal trends. Summer cooling is particularly important to Antarctic terrestrial ecosystems that are poised at the interface of ice and water. Here we present data from the dry valleys representing evidence of rapid terrestrial ecosystem response to climate cooling in Antarctica, including decreased primary productivity of lakes (6–9% per year) and declining numbers of soil invertebrates (more than 10% per year). Continental Antarctic cooling, especially the seasonality of cooling, poses challenges to models of climate and ecosystem change.
