Study: Antarctica has a ‘pause’ in warming – may be linked to ozone hole stabilization

Watts Up With That?

From the Steig et al. is still dead department:

The rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. Stabilisation of the ozone hole along with natural climate variability were significant in bringing about the change. Together these influences have now caused the peninsula to enter a temporary cooling phase. Temperatures remain higher than measured during the middle of the 20th Century and glacial retreat is still taking place. However, scientists predict that if greenhouse gas concentrations continue to rise at the current rate, temperatures will increase across the Antarctic Peninsula by several degrees Centigrade by the end of this century.

Reporting this week in the journal Nature researchers from British Antarctic Survey (BAS) describe how the stabilisation of the ozone hole and changing wind patterns has driven a regional cooling phase that is temporarily masking the warming influence of greenhouse…
