NASA flights gauge summer sea ice melt in the Arctic

  From NASA By Maria-Jose Viñas, NASA’s Earth Science News Team Earlier this year, Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic’s oldest and thickest sea…

The Ice Was All Between

Guest Post by Willis Eschenbach I do my best to maintain my sense of awe regarding the things I study. I’ve had the good fortune in my life to be a commercial fisherman on the Bering Sea, and to voyage and fish on the edges of the Arctic ice. To me, sea ice, whether fixed…

A Retrospective: Fun With Sea-Ice

At right: Portrait of the artist first writing on sea-ice; coastal Maine, January 1977 Guest essay by Caleb Shaw PART ONE Nearly forty years ago, back when nobody talked of Global Warming, I lived up on the coast of Maine during a series of remarkably cold winters in the late 1970’s, residing in a shack…

Now that the ‘Ship of Fools’ is safe in Antarctica, tough questions need to be asked

UPDATE: Perhaps the headline was premature, the latest SITREP from the rescue ship Aurora Australis indicates they are having some trouble getting into open water. UPDATE2: It seems the cause of getting stuck was nothing more than dawdling while sightseeing. Since the Guardian reporters shown above probably won’t do anything but complain about beds and…

Negative feedback? Storing CO2 in the Arctic

From the Massachusetts Institute of Technology: While the Arctic Ocean is largely a carbon sink, researchers find parts are also a source of atmospheric carbon dioxide For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent…

On data losses -vs- geography in Cowtan and Way 2013: data dropout may account for most of the recent observed differences

At Climate Audit, Roman M. has a very interesting analysis that shows the surface grid cell losses from HadCRUT4 in C&W. It hones in on the issue of why the temperature differences from 2005 are much more significant than the earlier part of the record. Data loss seems to be recently seasonally large, especially in…

Weekly Area of Snow Extent

Guest Post by Willis Eschenbach I got to thinking about snow the other day. It was occasioned by my look at the correlation (both positive and negative) of temperature and albedo. Albedo is a measure of how much sunlight is reflected from the clouds and the surface. The greater the albedo, the more sunlight is…

Tough Times For Sea Ice Melt Enthusiasts…

Image Credit: Cryosphere Today – University of Illinois – Polar Research Group By WUWT Regular Just The Facts In previous years there was reason to cheer, .e.g. “Transport is steaming full speed ahead.” “Some serious ice transport going on there. If this keeps up…” Neven, “Record Arctic Sea Ice Melt to Levels Unseen in Millennia”,…

Introducing The New WUWT Northern Regional Sea Ice Reference Page – With Observations

Image credits: (NSIDC) – The Perry-Castañeda Library Map Collection By WUWT regular “Just The Facts” We are pleased to introduce WUWT’s newest addition, the Northern Regional Sea Ice Page Sometimes lost in the Global Warming Causes Sea Ice Death Spiral rhetoric is the regional nature of changes in Northern Sea Ice, e.g. this paper, “…

The early chill in the Arctic continues

Temperature above 80 degrees north drops below freezing early, and continues to drop. Many people have been watching the remarkable early drop in air temperature at the DMI plot here: This drop looks to be about two weeks early. As this next analysis of sea surface temperature shows, much of the area is below freezing.…

UW issues statement on the ‘North Pole Lake’

From the University of Washington: Santa’s workshop not flooded – but lots of melting in the Arctic By Hannah Hickey Santa’s workshop at the North Pole is not under water, despite recent reports. A dramatic image captured by a University of Washington monitoring buoy reportedly shows a lake at the North Pole. But Santa doesn’t…

Avaaz! Save the world from a slushy death, just £2

People send me stuff. This is an email solicitation claiming that if you send Avaaz £2 a week (About $3.07 USD at current exchange rate) they’ll somehow be able to help NSIDC’s Julienne Stroeve get started putting back that Arctic ice, much like as a previous subscriber, you may have given money to help dolphins from…

SEARCH sea ice contest, call for contributions

WUWT has participated for the last two years, and I’ll post up a poll for the WUWT submission tomorrow. In the meantime, you can get a look at the current state of the Arctic Sea Ice at the WUWT Sea Ice Reference Page. Japan Graphic: Aerospace Exploration Agency (JAXA) – International Arctic Research Center (IARC)…

Modeling sea ice loss

From Wiley Study explores atmospheric impact of declining Arctic sea ice There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice…

Michael Tobis has bupkis

UPDATES have been added:  see below. Not only does Tobis have bupkis, he’s been caught out in a Janus moment from 2010 where he says the exact opposite. – Anthony I wrote a post yesterday pointing out how a WWF zealot immediately linked a heavy snowfall event in Moscow, Russia to ‘global warming’. Marc Morano…

Record Arctic Storm Melted Sea Ice

Image Credit: National Snow and Ice Data Center IUP Bremen From Live Science: Months before Hurricane Sandy hurled the Atlantic Ocean into houses and cities along the East Coast, another record-breaking cyclone battered North America, helping push this year’s Arctic sea ice to a record low, a new study finds. Arctic sea ice has been…

A Big Picture Look At “Earth’s Temperature” – “Extreme Weather” Update

By WUWT regular “Just The Facts” Recently there have been increased efforts to link “Climate Change” and “Extreme Weather” e.g., NOAA links extreme weather to climate change CBS – July 10, 2012, “NASA scientist links climate change, extreme weather” CNN – August 6, 2012 and Get used to ‘extreme’ weather, it’s the new normal The…

Arctic Ice and the DMI deficit

There’s been some interest in these before and after graphs highlighted by the blog “sunshinehours” here. Arctic Sea Ice Not As Bad As They Claimed??? DMI To me it looked like a data processing change at DMI (Danish Meteorological Institute) of some sorts, especially since none of the other metrics I monitor on the WUWT Sea…

Hamster wheels and sea ice explained

From the University of Calgary Utoday: Melting Arctic ice cap at record low – By Heath McCoy Think of a poor hamster on a spinning wheel, caught up by momentum and unable to stop until it’s overwhelmed, sent tumbling, crashing out of control inside. That’s the analogy John Yackel, head of the department of geography, makes…

New paper finds deep Arctic Ocean from 50,000 to 11,000 years ago was 1–2°C warmer than modern temperatures

Reposted from the Hockey Schtick A new paper published in Nature Geoscience finds “From about 50,000 to 11,000 years ago, the central Arctic Basin from 1,000 to 2,500 meters deep was … 1–2°C warmer than modern Arctic Intermediate Water.” This finding is particularly surprising because it occurred during the last major ice age. Horizontal axis is thousands of years…

ARCUS: July Sea Ice Outlook Published

WUWT comes in at the median value of 4.6 million square kilometers (they rounded up from our 4.55 submission) . It is important to note that even with the large losses in June, nobody who submitted to ARCUS is forecasting the “ice free arctic” to match Jay Zwally’s outlandish claim of “…the Arctic Ocean could…

A Big Picture Look At “Earth’s Temperature” – 2nd Quarter, 2012 – “What Global Warming Looks Like” Update

By WUWT regular “Just The Facts” In the US we are currently being bombarded with claims that “this summer is ‘what global warming looks like’” from the Associated Press and “summer heat wave an early indication of global warming” from MSNBC, as well as insinuations like “Record heat, derecho storm: Does global warming get blame?”…
