Redoubt volcano erupts again

4 04 2009

From the Alaska Volcano Observatory:

The significant explosive event at 06:00 AKDT has ended. Continuing seismic activity and web camera images indicate that low level emissions of steam, gas, and some volcanic ash are continuing to be emitted at the volcano at altitudes of < 20,000′.

Ashfall resulting from the 06:00 AKDT event has been reported in Homer, Anchor Point, and Seldovia.

The Mt. Redoubt alert level is currently WARNING and aviation color code is RED.

Bad news for Catlin Expedition: Satellite Data Shows Arctic Cooling in February and March

4 04 2009

Guest Post by Steven Goddard

As reported by Anthony, RSS satellite temperature data is out for March.  And as the Catlin adventurers have discovered, it has been “stupidly cold” in the Arctic.  March was the second consecutive month of below normal Arctic temperatures, and the continuation of a four year cooling trend – as seen below.   Google’s linest() function shows that since the beginning of 2005, Arctic temperatures have been cooling at a rate of 1.8 degrees C per decade, or 18C per century ( see comments).  Also note that Arctic monthly temperature anomaly now is about three degrees lower than in January, 1981.

That short term trend isn’t meaningful, except in the context of the Catlin Expedition and the cold they are experiencing.

Note in the graph below, the huge drop in temperatures since the Catlin expedition started two months ago.  Is this another example of The Gore Effect? Or, perhaps it is the “observer effect‘? Humor aside, the graph below tells the story of the cold the Catlin Expedition must be experiencing. Read the rest of this entry »
