Did the huge Greenland glacier break apart because of global warming? Maybe not. (+video)
An ice island about twice the size of Manhattan broke away from Greenland's Petermann Glacier last week, but the calving was likely caused by ocean currents, not global warming.

Ice, ice baby: Old arctic ice disappearing faster than younger thin ice
Typically the thicker, older ice survives through the summer melt season (hence, it's called multi-year ice), while the younger ice that forms over the winter melts as quickly as it formed.

Volcanic eruptions emerge as lead cause for Little Ice Age
The Little Ice Age began in the late 13th century, scientists now posit, and lasted about 400 years. Some regions cooled significantly. A series of volcanic eruptions has become a leading culprit.

Global warming: winners and losers in the Arctic's 'new normal'
The Arctic Report Card study suggests that changes at the top of the world have led to unusual weather patterns, a greener Greenland, and lots of plankton. At least the whales are pleased.
