The newly released Arctic Climate Impact Assessment’s alarmist claims of the unusual nature of the current state of the Arctic climate are inconsistent with long-term geological records of climate change in the region.
The newly released Arctic Climate Impact Assessment (ACIA) offers alarmist and highly questionable conclusions about the nature of Arctic climate and its variability. Consider the following statement, included in the Overview:
[The ACIA] is the largest, most comprehensive assessment of climate change in Arctic. The Arctic is experiencing some of the most rapid and severe climate change on earth. At least half the summer sea ice in the Arctic is projected to melt by the end of this century [as a result of increasing atmospheric CO2], along with a significant portion of the Greenland Ice Sheet, as the region is projected to warm an additional 4-7ºC (7 to 13ºF) by 2100.
We find serious problems with all three of these major sentiments.
