The Arctic’s near-record sea ice low – big picture


A view from space of Arctic sea ice at a near record low this month. Scientists in Germany, who use a different methodology, said 2011 was a record low

The Arctic's near-record sea ice low – big picture

By early September, the area covered by sea ice in the Arctic Ocean was approaching a record low. On September 9, sea ice covered 4.33 million square kilometers (1.67 million square miles), US National Snow and Ice Data Center reported. The 2011 low is 2.38 million square kilometers (919,000 square miles) below the average minimum extent measured between 1979 and 2000. Late season melt or a shift in wind patterns could still decrease the sea ice extent before the winter freeze-up begins. Photograph: AMSR-E/Aqua/NASA

From the Himalayas to the Arctic, the signs of danger are visible

Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity. From the frosted plains of the Arctic ice pack to the cool blue caverns of the mountain glaciers, the dripping away of frozen water is the most crystal clear of all the Earth’s warning signals.

One Response to The Arctic’s near-record sea ice low – big picture

  1. George Ennis says:

    What is interesting is that the minimum for 2011 was reached despite weather conditions as they existed in 2007 being far from ideal. The question raised by the rapid melt despite ideal atmospheric conditions is why? The belief is that the ice in many places is simply melting from below combined with the fact that the volume of ice is believed to be at record lows. Should the atmospheric conditions that prevailed in 2007 repeat themselves (it was considered a 1 in 20 year event) then there is speculation that we could be in for a dramatic loss in extent, area and volume.
