More so than the climate alarm movement thought, anyway. Hence all the failed predictions of disappearing summer sea ice in the Arctic, and erroneous claims of ‘rapid melting’ that no longer hold water
Observations show a ‘sideways trend’ in Arctic sea ice volume since around 2010, which perhaps not by chance follows a significantdownturn in solar cycle intensity.

In recent years the Arctic sea ice has shown great resiliency and is currently at higher levels for this time of year when compared to all but two years going back to 2005, says meteorologist Paul Dorian of Perspecta Inc. (via The GWPF).
Sea ice covers about 7% of the Earth’s surface and about 12% of the world’s oceans and forms mainly in the Earth’s polar regions.
Specifically, much of the world’s sea ice is found within the Arctic ice pack of the Arctic Ocean in the Northern Hemisphere and the Antarctic ice pack of the Southern Ocean in the Southern Hemisphere.
While the Antarctic sea ice extent is currently running at levels very close-to-normal, the Arctic sea ice extent is below-normal and has been running generally at below-normal levels since the middle 1990’s at which time there was a long-term phase shift from cold-to-warm in the North Atlantic Ocean sea surface temperature pattern.
In recent years, however, the Arctic sea ice has actually shown great resiliency and is currently at higher levels for this time of year when compared to all but two years going back to 2005.
