Recent cooling in coastal southern Greenland and relation with the North Atlantic Oscillation
Analysis of new data for eight stations in coastal southern Greenland, 1958-2001, shows a significant cooling (trend-line change -1.29°C for the 44 years), as do sea-surface temperatures in the adjacent part of the Labrador Sea, in contrast to global warming (+0.53°C over the same period). The lan...

Summary: | Analysis of new data for eight stations in coastal southern Greenland, 1958-2001, shows a significant cooling (trend-line change -1.29°C for the 44 years), as do sea-surface temperatures in the adjacent part of the Labrador Sea, in contrast to global warming (+0.53°C over the same period). The land and sea temperature series follow similar patterns and are strongly correlated but with no obvious lead/lag either way. This cooling is significantly inversely correlated with an increased phase of the North Atlantic Oscillation (NAO) over the past few decades (r = -0.76), and will probably have significantly affected the mass balance of the Greenland Ice Sheet. |
