In February, record high temperatures in the Arctic brought with them other records — including record lows for that month’s extent and area of Arctic sea ice.
Until this year, the previous records for sea ice extent and area for February were set in 2011.
Moreover, the total volume of the Arctic sea ice, which many scientists see as the most important factor determining the health of Arctic sea ice, reached its second-lowest level ever recorded that same month. The record low for sea ice volume was set in 2012, a record that could fall this year or next, according to scientists.
As anthropogenic climate disruption (ACD) continues to outpace most of the worst-case predictions given by scientists, the melting happening in the north provides us with one of the most iconic examples of what our fossil fuel-based economy is costing the planet.
Record Arctic Heat
According to NASA, the Arctic was a shocking 18 degrees Fahrenheit warmer than normal for the month of February, which was one of the key factors driving the new low records for sea ice.
February in the Arctic was so warm that it was the single largest recorded monthly “temperature anomaly” (a deviation from the 1951-1980 averages) ever. February saw a 2.4 degree Fahrenheit deviation, and the previous record deviation (set in January) was 2 degrees Fahrenheit.
Providing more disturbing context for the warming trends, The Weather Channel noted, “The five largest monthly global warm anomalies in NASA’s database have all occurred within the past five months.”
And the trends for Arctic sea ice continue in the wrong direction. Sea ice data provided by the Polar Science Center even indicated that, during some days in March so far, sea ice volume measurements briefly reached record lows. By early March, volume totals were already reaching the second-lowest volume ever recorded.
Robbed of Winter
Since January, Arctic temperatures have been in record or near-record…
