The fact this is seemingly not fully recognized — or here integrated — by Curry goes to the same reason Curry does not recognize why the so called «pause» is a fiction, why the «slowing» of the «rate» of increase in average ambient global land and ocean surface air temperatures over a shorter term period from the larger spike beyond the longer term mean of the 90s is also meaningless in terms of the basic issue, and why the average ambient increase in global air temperatures over such a short term is by far the least important empirical indicia of the issue.

What the report says about climate change and the Arctic: Over the past 50 years, near - surface air temperatures across Alaska and the Arctic have increased at a rate more than twice as fast as the global average.

The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and, indirectly, from increases in average global sea levels, retreating glaciers, and changes in many physical and biological systems.
