Hot Arctic Water, High Pressure Domes Pushing Sea Ice Toward New Record Lows

Hot Arctic Water, High Pressure Domes Pushing Sea Ice Toward New Record Lows | Garry Rogers Nature Conservation News | Scoop.it

It doesn't take much to shove Arctic sea ice toward new record low values these days. Human caused climate change has made it easy for all kinds of weather systems to bully the ice.


In the case of the past seven days, three moderate strength high pressure cells churned away over the central Arctic, bringing with them clear skies, air temperatures in the range of average for 1979-2000 above the 70 North Latitude line, and a clockwise circulation favoring sea ice compaction and warm water upwelling at the ice edge.

The highs measured in the range of 1020 to 1025 hPa barometric pressure. Moderate-strength weather conditions that during a typical year of the last century would have been almost completely non-noteworthy. Today, instead, we have sea ice extent testing new record lows in the Japanese Space Agency’s monitor.

Garry Rogers's insight:

On the chart, the red line for 2014 intersects the 2011 & 2012 as it reaches July. Will it fall below them as the year progresses?

Late June 2014: Arctic in Hot Water as Sea Ice Thins and Tundra Fires Erupt

"Atmospheric warming due to human-caused climate change. It's the general measure we've used to track a devastating and ongoing heat amplification due to a terrible greenhouse gas emission. But if we were to look for where the greatest amount of that heat has accumulated, it would be in the world’s oceans. For from its air-contacting surface to its depths thousands of meters below, the World Ocean has captured 93.4% of the total heat forcing humans have already unleashed. The remainder is almost evenly divided between the atmosphere, the continents, and the ice."
