2016 SkS Weekly Digest #38

Story of the Week...

Arctic sea ice appears to have reached its seasonal minimum extent for 2016 on September 10. A relatively rapid loss of sea ice in the first ten days of September has pushed the ice extent to a statistical tie with 2007 for the second lowest in the satellite record. September’s low extent followed a summer characterized by conditions generally unfavorable for sea ice loss.

2016 ties with 2007 for second lowest Arctic sea ice minimum, National Snow & Ice Data Center (NSIDC), Sept 15, 2016

This is a preliminary announcement. Changing winds or late-season melt could still reduce the Arctic ice extent, as happened in 2005 and 2010. NSIDC scientists will release a full analysis of the Arctic melt season, and discuss the Antarctic winter sea ice growth, in early October.

SkS Highlights...

Using the metric of comments garnered, Weekly Digest #37 was the most popular of the items posted on SkS during the past week. BBC climate coverage is evolving, but too slowly by Dana Nuccitelli (Climate Consensus - the 97%, The Guardian) was the second most popular. The Climate Change Authority report: a dissenting view by Clive Hamilton & David Karoly (The Conversation AU) came in third.

Quote of the Week... 

“Donald Trump lives in a parallel universe where the facts established by the scientific community to him don’t exist,” said Anthony Leiserowitz, director of the Climate Change Communication program at Yale University.

“The fact is that climate change is here and now. It’s not some faraway, distant problem that we’re not going to see for a generation or two.”

SkS in the News...

In his article, Experts dispute statements made at Uintah Basin Energy Summit, Joshua Murdock states:

In fact, the 97 percent consensus was not a poll of less than 100 scientists, as Morano said, but rather an analysis of more than 4,000 climate change studies, 97.2 percent of which indicated that climate change was real and affected by human activity. A previous study found that 75 percent of climate change studies supported anthropogenic climate change. Many studies, including ones in 20092010 and 2015, support Alley and Schmidt's statements.

Video of the Week...

In this animation, the Earth rotates slowly as the Arctic sea ice advances over time from March 24, 2016 to September 10, 2016, when the sea ice reached its annual minimum extent. The 2016 Arctic minimum sea ice extent is the second lowest minimum extent on the satellite record.
