Can Humans Melt the Antarctic Icecap?

Can we puny humans produce enough energy to melt the huge icecap? Some math helps. Guest essay by Julius Sanks When discussing climate with people who do not have technical backgrounds, I have learned much of the climate discussion is a foreign language to them. Phrases like “Dalton minimum” or “Atlantic multidecadal oscillation” make their eyes…

The Penguins Smoking Hockey Schtick

Guest essay by James Wanliss It is a tough life in Antarctica. Average winter temperature at the South Pole is about -49°C. The coldest temperature ever recorded by a thermometer in Antarctica was -89.2°C at Vostok station in 1983. (This is the same as -128.6°F.) Satellite measurements have found temperatures as low as a frigid…

OK, here is press release #1 from the UNIVERSITY OF SOUTH FLORIDA (USF HEALTH) Melting of east Antarctic ice sheet could cripple major US cities TAMPA, Fla (December 13, 2017)- The world’s largest ice sheet may be less stable than previously thought, posing an even greater…

A normal part of nature – sea ice retreat in Antarctica

From the UNIVERSITY OF CAMBRIDGE ‘Scars’ left by icebergs record West Antarctic ice retreat ten thousand years ago – occurred under climate conditions that were relatively similar to those of today. Thousands of marks on the Antarctic seafloor, caused by icebergs which broke free from glaciers more than ten thousand years ago, show how part of the…

News From Vostok Ice Cores

Guest essay by Richard Taylor Introduction Our current understanding climate was influenced profoundly by the publication (J.R. Petit, et al., 1999) of deuterium (2H) measurements from metre 8 to metre 3310 of the Vostok ice-core, indicating the temperature of the nearby atmosphere from 1800 to 421000 BC. Some authorities claim, and many believe, that unprecedented…

Giant hole in ice reappears in Antarctica after 40 years

Antarctica: Return of the Weddell polynya supports Kiel climate model After 40 years, a large ice-free area appears again in the Southern Ocean in mid-winter Currently, winter has still a firm grip on Antarctica. At this time of the year, the Weddell Sea usually is covered with a thick layer of sea ice. In spite…

The study’s…

Media gets high on Antarctic Crack

I thought I’d take a moment from my R&R to write about all the hullabaloo surrounding the calving of the large iceberg off the Larsen C ice shelf in Antarctica. First, a few of the headlines: LA Times: After Antarctica sheds a trillion-ton block of ice, the world asks: Now what? The Grauniad: Iceberg twice size of…

Climate change impacts Antarctic biodiversity habitat

From the University of Queensland IMAGE: Climate change impacts Antarctic biodiversity habitat. view more Credit: Peter Ryan Ice-free areas of Antarctica – home to more than 99 per cent of the continent’s terrestrial plants and animals – could expand by more than 17,000km2 by the end of this century, a study published today in Nature…

Oh noes! Antarctica ‘greening’ due to climate change

From the “greening of the planet must be a bad thing” department and the UNIVERSITY OF EXETER comes this breathless missive. Note: one species of moss is not equal to the implied “all plant life” in their sub-headline. Additionally, sampling only three sites isn’t necessarily a representative sample of Antarctica. PUBLIC RELEASE: 18-MAY-2017 Antarctica ‘greening’ due to…

Oh noes! Antarctic ice rift spreads

From SWANSEA UNIVERSITY and the “if ice cracked in the Antarctic before airplanes and satellites existed, did it make a visual?” department. New branch revealed in latest data from ice shelf The rift in the Larsen C ice shelf in Antarctica now has a second branch, which is moving in the direction of the ice…

Oops, Warmists just lost the Antarctic peninsula – it is now cooling

A warming trend of 0.32 °C/decade during 1979–1997 to a cooling trend of − 0.47 °C/decade during 1999–2014. Remember the much ballyhooed paper that made the cover of Nature, Steig et al, “Warming of the Antarctic ice-sheet surface since the 1957 International Geophysical Year”, Nature, Jan 22, 2009 that included some conspicuously errant Mannian math from the master of making…

Föhn winds: New insight into what weakens Antarctic ice shelves

New research describes for the first time the role that warm, dry winds (katabatic winds) play in influencing the behaviour of Antarctic ice shelves. Presenting this week at a European conference scientists from British Antarctic Survey (BAS) explain how spring and summer winds, known as föhn winds, are prevalent on the Larsen C Ice Shelf,…

The horror! Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm

From the RESEARCH ORGANIZATION OF INFORMATION AND SYSTEMS and “it’s just a number” department, comes this breathless press release. Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm According to the 57th Japan Antarctic Research Expedition (JARE)/National Institute of Polar Research (NIPR), a daily mean atmospheric CO2 concentration value of 400.06 ppm was…

Increasing Antarctic snowfall may offset sea-level rise

From THE EARTH INSTITUTE AT COLUMBIA UNIVERSITY By mid-century, more Antarctic snowfall may help offset sea-level rise Increasing precipitation masked by natural variability — for now When Antarctica’s air temperature rises, moisture in the atmosphere increases. That should mean more snowfall on the frozen continent. So why hasn’t that trend become evident in Antarctica’s surface…

Expanding Antarctic sea ice linked to natural variability

From the NATIONAL CENTER FOR ATMOSPHERIC RESEARCH/UNIVERSITY CORPORATION FOR ATMOSPHERIC RESEARCH BOULDER — The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for Atmospheric Research (NCAR). The…

Why does the Antarctic sea ice trend resist decline?

From NSIDC: Antarctic sea ice: an update Antarctic sea ice extent continues to make headlines because it has grown even as much of the globe, and Antarctica itself, is warming. Arctic sea ice, in contrast, is showing a marked decline. Warmer air and ocean waters are bathing both poles, so why does the Antarctic 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…

The Warmer The Icier

Guest Post by Willis Eschenbach A WUWT commenter emailed me with a curious claim. I have described various emergent phenomena that regulate the surface temperature. These operate on time scales ranging from minutes to hours (e.g. dust devils, thunderstorms) to multi-decadal (e.g. Atlantic Multidecadal Oscillation, Pacific Decadal Oscillation). He suggested that there is also a…
