The trend has increased sharply twice in the last five decades. This is a finding that all but four of the 39 climate models missed.

On a smaller time scale and, contrary to previous investigations which found that the Arctic amplification index increased smoothly, we observed two distinct steps, one in 1986 and the second in 1999. . Petr Chylek, Lead Author of the Study, Physicist and Climate Researcher, Los Alamos . National Laboratory The study was reported in the journal Geophysical Research Letter. Decade-by-decade episodic trends defined by Chylek and his collaborators tend to have an impact on global sea levels and weather, which precisely projectin...
