Because it's Spring. In the Southern Hemisphere, however, it's Fall and it's getting colder. The sea ice in the North has probably peaked and is down from the 21 year normal by half a million square kilometers. Most of the anomaly is from two places--Barents Sea and the Sea of Okhotsk. In the South, the sea ice around Antarctica is more than a million and a half square kilometers above the 21 year normal. Therefore world sea ice is a million square Km above normal. The flux density from the sun is low, 71, and the sun is spotless and still hasn't had a normal second new cycle sunspot since January 4, 2008. The four different measurements of global temperature are rebounding from the year long full degree slide.
I'm speculating that there is a recently active volcano under the ice near the base of the Antarctic Peninsula which accounts for the recent melting only there in Antarctica. Is there any way to tell? It is difficult otherwise to account for the record sea ice (which would mean colder than normal temperatures) and single source of ice shelf collapses (which would require warmer than normal temperatures).
Huge, decade long drought continues in Australia, Spring flooding in America's upper south.
In other words, another normal Spring/Autumn here on our beautiful planet.
