This Summer in the Arctic

As reported previously on this blog, Arctic sea ice rebounded this summer. About half of the sea ice survived the summer melt. Last summer's sea ice hit a record low. The rebound did not seem to surprise some scientist because two record lows in a row have yet to be recorded since Arctic sea ice levels have been tracked. During my visit to the Arctic (Aug. - Sept. 2013), on-board the USCGC Healy, many observers commented on the relative abundance of polar bear sightings . This news of a sea ice rebound would also be welcome to the native Inupiaq peoples of Alaska, since subsistence hunting of whales is a continuing cultural practice. More on the Arctic sea ice rebound here .

Are There Consequences to a Warming Arctic?

Could a rapidly warming Arctic create crazy storms? (Fox41 Blog) In an article written by Stephanie Paige Ogburn in Scientific American , a question was poised: Does a warming Arctic affect mid-latitude weather? Sandy-like events are receiving a lot of media attention, and many are wondering if there is a link to climate change. "R apid warming in the Arctic is changing the way the jet stream behaves. Since the jet stream is a driving force behind weather over the temperate part of the Earth, also known as the mid-latitudes, many people would be affected by this switch." Jennifer Francis , a climate scientist at Rutgers, has been working on this hypothesis that a warming Arctic has a link to crazy weather events. Though she admits the signal is somewhat weak at this point, the body of evidence is gathering. "Arctic sea ice extent continues to plunge below average each summer. Measurements have shown that the winds that blow west to east and drive the jet ...

Polar bears are enjoying the "abundance" of Arctic sea ice this year According to many people in-the-know, Arctic sea ice is relatively abundant this year. Towards the end of July 2013, " Arctic sea ice actually expanded by 20,000 square kilometers ," according to Jason Samenow of the Washington Post. This is not to say Arctic sea ice is healthy as it has ever been; quite the opposite . In a NOAA report , 2012 was one of the warmest since climate records have been kept. The Arctic, according to the report, is warming faster than other places on Earth. This year's better-than-expected sea ice seems to be really welcome news to polar bears, however. During this cruise, I have personally made visual contact with five polar bears. While others on the cruise--mainly Martin Reedy, Arctic wildlife observer for U.S. Fish and Wildlife, whose job is to count these beautiful creatures--have probably seen double what I have. Polar bears are lovely; polar bears...
