80,000 Yrs of Arctic Ice Melted in Single Weekend

News Brief by Kip Hansen   No, really…no kidding here…this is a real disaster.   This is not Fake News! Here’s the story, from the NY Times’ Tatiana Schlossberg (and here): “Ice from the Canadian Arctic has completely melted, leaving puddles of water in its place and scientists devastated. O.K., this is what actually happened: Ice…

Arctic Albedo Variations

Guest Post by Willis Eschenbach Anthony has just posted the results from a “Press Session” at the AGU conference. In it the authors make two claims of interest. The first is that there has been a five percent decrease in the summer Arctic albedo since the year 2000: A decline in the region’s albedo –…

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…

Climate as a heat engine

Guest essay by Jan Kjetil Andersen As Willis describes in his article on December 21, the atmosphere can be seen as a gigantic heat engine, i.e. a machine which convert thermal energy, namely temperature, into mechanical energy, namely wind. It may seem a bit strange to view the weather system as a kind of machine…

IPCC’s Report on Climate Change: Myths & Realities

A World Meteorological Organization insider’s view of the IPCC report. Guest essay by Dr. S. Jeevananda Reddy Formerly Chief Technical Advisor – WMO/UN [A note to readers: English is not Dr. Reddy’s primary language. I have made some edits to his original manuscript for clarity, but some readers may find the writing style a bit…

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…

Cowtan & Way off course

By Christopher Monckton of Brenchley This time last year, as the honorary delegate from Burma, I had the honor of speaking truth to power at the Doha climate conference by drawing the attention of 193 nations to the then almost unknown fact that global warming had not happened for 16 years. The UN edited the…

Inverse Underwater Hockey Sticks?

From the University of Toronto,  Underwater ‘tree rings’ Calcite crusts of arctic algae record 650 years of sea ice change Almost 650 years of annual change in sea-ice cover can been seen in the calcite crust growth layers of seafloor algae, says a new study from the University of Toronto Mississauga (UTM). “This is the…

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”,…

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.…

Will the Cost of the Climate Wars be the BBC’s Integrity?

Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University. On July 29, 2013 the BBC’s Hardtalk journalist Stephen Sackur wrote “The Alaskan village set to disappear under water in a decade.” He opened the story with “within a decade Kivalina is likely to be under water. Gone, forever. Remembered…

Remarkable correlation of Arctic sea ice to solar cycle length

This is interesting, especially since Solar Cycle 23 was quite long. The Hockey Schtick writes: A paper published by the Danish Meteorological Institute finds a remarkable correlation of Arctic sea ice observations over the past 500 years to “the solar cycle length, which is a measure of solar activity. A close correlation (R=0.67) of high significance (0.5…

How “Science” Counts Bears

Guest essay by Jim Steele, director emeritus, San Francisco State University The Inuit claim “it is the time of the most polar bears.” By synthesizing their community’s observations they have demonstrated a greater accuracy counting Bowhead whales and polar bears than the models of credentialed scientists. To estimate correctly, it takes a village. In contrast…

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…

Paper: ‘Summer temperatures were about 10°C warmer than today, even though the concentration of atmospheric CO2 was similar’

From AAAS: From Russia with Lovely Data Climate and the atmospheric concentration of CO2 are closely linked. Brigham-Grette et al. (p. 1421, published online 9 May) present data from Lake El’gygytgyn, in northeast Arctic Russia, that shows how climate varied between 3.6 and 2.2 million years ago, an important interval in the global cooling trend…

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…

Climate models getting worse than we thought

New paper finds climate models are getting worse rather than better Via the Hockey Schtick: A paper published today in Geophysical Research Letters finds that the latest climate models are performing even worse than the earlier generations of climate models in predicting “…both the mean surface air temperature as well as the frequency of extreme…

Arctic methane emergency called off?

Here’s the issue, as described in Wikipedia: The Arctic region is one of the many natural sources of the greenhouse gas methane. Global warming accelerates its release, due to both release of methane from existing stores, and from methanogenesis in rotting biomass. Large quantities of methane are stored in the Arctic in natural gas deposits,…
