Pine Island Glacier spawns a giant iceberg

As David Spratt posted at Climate Code Red a giant crack has opened across the full width of the Pine Island Glacier (PIG) ice shelf, spawning a new iceberg about 720 square kilometres in area, roughly eight times the size of Manhattan Island in New York. This is about the best photo I can find:

We’ll get some orientation first and then look at the implications. This image locates the PIG on the continent of Antarctica:

This image from the LiveScience photo gallery outlines the PIG basin:

This basin together with the Thwaites Basin just to the south drains 40% of West Antarctica. These two glaciers alone could lead to sea level rise of half a metre by 2100 according to material cited by Spratt. Continue reading Pine Island Glacier spawns a giant iceberg

Stormy weather

2010 possibly the worst ever for extreme weather

That’s according to über-meteorologist Jeff Masters posting at Climate Progress.

The year was extraordinary, featuring the hottest year on record equalling 2005, the most extreme winter Arctic atmospheric circulation on record, the warmest and driest winter on record for North America-Canada, the lowest volume of Arctic sea ice on record and 3rd lowest in extent, a record melting in Greenland, the second most extreme shift from El Niño to La Niña, the second worst coral bleaching year, the wettest year over land, the Amazon rainforest experienced its 2nd 100-year drought in 5 years and, it must be said, we had the lowest global tropical cyclone activity on record. Here’s the precipitation graph: Continue reading Climate clippings 33
