Polar Bare: The Humanitarian Community's Brave New World
"Amazing," "astonishing" and "extraordinary" are three words to explain this summer's ice melt in the arctic circle. According to analysis by Dr. Jeff Masters of the Weather Underground, almost half of the Arctic ice cap disappeared this summer, an occurrence which may have last occurred 1,450 years ago, 4,000 years ago, or between 6,000-8,000 years ago. Prior to that, Masters indicates that the last time the Arctic was this ice free was 120,000 years ago during the last inter glacial period (when seas were also 4-6 meters higher).
For the humanitarian community, the reality of an ice-depleted Arctic has significant implications. Not just for organizations operating at the highest latitudes of the planet, but for those operating in the "southern" countries as well. The short term implications of an ice free Arctic may have already manifested in some surprising locations – North Africa, the Middle East, the Balkans, the Indian Subcontinent and even Latin America.
"blocking" and "persistent" weather patterns can set in. Droughts can linger for greater periods of time, heat waves can simmer and cold snaps can be locked into place. As described below, the massive U.S. drought of 2012 and the deadly 2010 Russian heat wave are two potential examples of this.
- U.S. Drought and Crop Loss (2012) – with 2012 being the hottest year on record in the U.S., the accompanying drought has ravaged the agricultural sector and raised global food prices. The drought has been tied into Arctic-influenced blocking patterns.
- Russian Heat Wave (2010) – with over 50,000 fatalities and raging forest fires, the extreme Russian heat wave has also been linked to a blocking pattern, possibly of Arctic melt-influenced origin.
- Pakistan Floods (2010) – the epic flooding in Pakistan that affected 20 million people was also correlated to the same blocking pattern that set up over Russia in 2010, according to NASA.
- Cold Wave of 2012 – a negative phase of the Arctic Oscillation brought frigid conditions to Europe for much of last winter, paralyzed Turkey's Lake Van earthquake impact zone, and had substantial humanitarian impacts (and operations) from Kosovo to Algeria to Tunisia.
- Cold Wave of 2011 – a negative Arctic Oscillation brought frigid temperatures as far south as Mexico, bringing wind chills as far as minus 15 degrees and forcing some residents to shelters. Over 2,600 people sought shelter from the cold as far south as Guatemala.
- Cold Wave of 2010 – a negative Arctic Oscillation was so prominent in North America that some parts of the Florida were colder than Antarctica. Cold waves gripped South Asia, Central Asia, and parts of Latin America. Severe crop losses due to the cold were even reported in Yemen.
