Record low volume highlights exceptional year for Arctic sea ice

With the latest sea ice data for November just in, 2016 continues to be a dramatic year in the Arctic. Following an unusually warm start to the year and record low ice in several months, a markedly sluggish freeze-up season in the back end of the year is also seeing records tumble.

Earlier this week, scientists confirmed the area of Arctic Ocean covered by sea ice – known as sea ice extent – reached a record low in November. Now, figures from the Piomas (Pan-Arctic Ice Ocean Modeling and Assimilation System) confirm the volume of sea ice also hit record lows.

At close to 8,000 cubic kilometres (cubic km), total sea ice volume in November stood at just 48% of the long-term average and the smallest of any November in the satellite record stretching back to 1979.

Taken together, these findings show little sign of recovery after an exceptionally poor start to the winter freeze-up season. This doesn’t bode well for survival of the ice through next year’s summer melting season, say scientists.

Quote of the Week...

The Union of Concerned Scientists, for its part, is preparing for a world in which government scientists might face serious workplace restrictions. It is girding for battle, ready to receive information securely” and “anonymously” should scientists encounter censorship from political appointees.

“We’ve been to this rodeo before, although the bull this time is a bit tougher,” wrote Michael Halpern, the union’s deputy director of the Center for Science and Democracy, in an email. “Science advocacy used to be primarily about securing funding for research. Now many more scientists care just as much about how the science they create is used or misused to create policy. . . . We’ve heard all kinds of reactions to the election, but we haven’t heard indifference.”

SkS in the News...

In their WunderBlog (Weather Underground) article, Climate Change Won’t Stop in 2016, Despite Misleading Report, Bob Henson & Jeff Masters prominently discuss and display the following SkS graphic:

ENSO Global Temperature Influence

Figure 2. Global surface temperature trends for the period 1966 - 2015 analyzed for El Niño years (red boxes), La Niña years (blue boxes), and neutral years (black boxes), along with volcanic years (gold triangles). The three trend lines show that global temperature has been rising at a fairly consistent rate of about 0.15 - 0.17°C (0.27 - 0.31°F) per decade once La Niña and El Niño departures are factored out.

The above graphic is also prominently included in The Weather Channel article, Note to Breitbart: Earth Is Not Cooling, Climate Change Is Real and Please Stop Using Our Video to Mislead Americans.

SkS Spotlights

Moms Clean Air Force is a community of 950,000 moms and dads united against air pollution – including the urgent crisis of our changing climate – to protect our children’s health. We arm members with reliable information and solutions through online resources, articles, action tools, and on-the-ground events. We work across the US on national and local policy issues, through a vibrant network of 18 state-based field teams. Our moms meet with lawmakers at every level of government to build support for commonsense solutions to pollution. Moms have passion and power – an unbeatable combination. We are harnessing the strength of mother love to fight back against polluters.

Extreme Weather & Climate Change - What's our Response?

Climate change brings dangerous challenges as extreme weather events like heat waves, floods, and wildfires impact Colorado and the U.S.  But will public awareness now support the necessary transition of the U.S. energy system to one capable of mitigating climate change? Can denialism be overcome? What are the prospects for national action?

Phil Nelson chairs the Golden Chapter of Citizens’ Climate Lobby, a volunteer nonpartisan group that promotes putting a price on carbon to counter climate change.  CCL’s plan will reduce greenhouse gases while actually boosting the economy.  Dr. Nelson is an MIT trained retired geophysicist.
