Australia Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica.
“Sea ice conditions have remained stable in Antarctica generally,” Allison said.
Ice core drilling in the fast ice off Australia’s Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Center shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years.
A paper to be published soon by the British Antarctic Survey in the journal Geophysical Research Letters is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded.
Just one-out-of-three voters (34%) now believe global warming is caused by human activity,
Forty-eight percent (48%) of all likely voters attribute climate change to long-term planetary trends, while seven percent (7%) blame some other reason. Eleven percent (11%) aren’t sure.
These numbers reflect a reversal from a year ago when 47% blamed human activity while 34% said long-term planetary trends.
