Arctic sea ice extent above levels not seen since 2013

Arctic sea ice extent above levels not seen since 2013

Arctic’s seasonal sea ice loss began more slowly in May 2022 than in the recent years as air temperatures were closer to the 1981 to 2010 average. The month ended with the highest sea ice extent since 2013 – the 14th lowest in the satellite record.

Siberian town records possible hottest-ever temperature in Arctic Circle

Siberian town records possible hottest-ever temperature in Arctic Circle

The town of Verkhoyansk in Siberia hit 37.8 °C (100 °F) for the first time on Saturday, June 20, 2020– if verified, it will be the hottest-ever temperature recorded above the Arctic Circle. The hot temperature recorded in Verkhoyansk on Saturday may also…

Arctic ozone levels hit record low in March

Arctic ozone levels hit record low in March

An analysis of satellite observations shows that ozone levels over the Arctic hit a record low for the month of March, NASA researchers reported on April 16, 2020. Ozone levels reached their lowest point on March 12 at 205 Dobson units. The depletion was caused by…

Rare ozone hole opens over the Arctic, likely the largest in history

Rare ozone hole opens over the Arctic, likely the largest in history

A huge ozone hole has opened this year over the Arctic. While ozone holes normally form in the Antarctic zone every year because winter temperatures drop to extremely low values, allowing high-altitude clouds to develop– the Arctic has more varying temperatures and…

Polar Stratospheric Clouds form over Sweden

Polar Stratospheric Clouds form over Sweden

Polar stratospheric clouds, reported on December 9, 2016, over the skies of Kiruna, Sweden, indicate the stratosphere above the Arctic Circle is getting very cold. Polar stratospheric clouds (PSCs) form from the icy particles in the lower stratosphere, in extremely…

Satellites measure increase of Sun’s energy absorbed in the Arctic

Satellites measure increase of Sun’s energy absorbed in the Arctic

NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 – a trend that aligns with the steady decrease in Arctic sea ice during the same period.While sea ice is mostly white and reflects the sun&rsqu

Increase in Arctic cyclones linked to climate change, new study shows

Increase in Arctic cyclones linked to climate change, new study shows

Winter in the Arctic is not only cold and dark, it is also storm season when hurricane-like cyclones traverse the northern waters from Iceland to Alaska. These cyclones are characterized by strong localized drops in sea level pressure, and as Arctic-wide decreases in

Arctic cyclones more common than previously thought

Arctic cyclones more common than previously thought

Weather data at the Ohio Supercomputer Center reveals in a new study hundreds of smaller storms that had previously escaped detection.

From 2000 to 2010, about 1 900 cyclones churned across the top of the world each year, leaving warm water and air in their

Two massive lakes discovered underneath the Greenland Ice Sheet

According to recently published study, two massive subglacial lakes have been discovered 800 meters beneath surface of the melting Greenland Ice Sheet. Lakes discovered by researchers from the Scott Polar Research Institute (SPRI) at the University of
