NASA: Arctic Sea Ice Reaches Annual Minimum

September 22, 2022

National Center for Snow and Ice Research:

On September 18, Arctic sea ice likely reached its annual minimum extent of 4.67 million square kilometers (1.80 million square miles). The 2022 minimum is tied for tenth lowest in the nearly 44-year satellite record, with 2018 and 2017. The last 16 years, from 2007 to 2022, are the lowest 16 sea ice extents in the satellite record.

In the Antarctic, sea ice extent has hit record lows through most of the growth season. Starting in early August, sea ice began expanding rapidly, exemplifying the strong degree of variability in Southern Hemisphere sea ice. As such it is too early to assume that the maximum has been reached as storms may still expand or compact the extended ice edge. The maximum for Antarctic sea ice typically occurs in late September or early October.

Please note that this is a preliminary announcement. Changing winds or late-season melt could still reduce the Arctic ice extent, as happened in 2005 and 2010. NSIDC scientists will release a full analysis of the Arctic melt season, and discuss the Antarctic winter sea ice growth, in early October.

    Since “Sea Level Rise”, “Arctic Ice” and “Antarctic Ice” are the end result of “Global Warming” then humanity has all the proof we need. Now we must act.
