Top Scientists: CO2-Induced Warming Is “Weak” To Non-Existent For Greenland, Antarctica!
We routinely read about “highest ever” Arctic ice sheet and sea ice melt rates in the Arctic. And about rapid, “faster-than-expected” melting of ice shelves in West Antarctica. And then, of course, we’re told that sea levels are rising at an accelerating rate — a catastrophically accelerating rate — due to the amplified warming at the poles, or “polar amplification”.
The predominant cause of these alarming climate changes is almost invariably attributed to anthropogenic CO2 emissions, of course. These headlines are now commonplace, designed to grab our attention and stir us to action. But does the scientific evidence confirm that the polar climate is predominantly determined by the rise in anthropogenic CO2 emissions?
A warming and cooling Arctic
As documented in the below Climate4you graph (HadCRUT4), the Arctic climate has followed a roughly 60-year oscillation in the last century. Arctic (70-90 N) temperatures warmed during the 1920s to 1940s, cooled during the 1950s to1990s, and then returned to a warming trend from the mid-1990s onward.
