For many years, climate realists have pointed to expanding ice in Antarctica as a counter to the claim that decreasing ice in the Arctic is necessarily proof of anthropogenic global warming.
The folks at the Associated Press on Wednesday came up with an unbelievable answer to that in an article unbelievably titled “Experts: Global Warming Means More Antarctic ice”:
While the North Pole has been losing sea ice over the years, the water nearest the South Pole has been gaining it. Antarctic sea ice hit a record 7.51 million square miles in September. That happened just days after reports of the biggest loss of Arctic sea ice on record.
Climate change skeptics have seized on the Antarctic ice to argue that the globe isn’t warming and that scientists are ignoring the southern continent because it’s not convenient. But scientists say the skeptics are misinterpreting what’s happening and why. (more…)
Antarctic sea ice set another record this past week, with the most amount of ice ever recorded on day 256 of the calendar year (September 12 of this leap year). Please, nobody tell the mainstream media or they might have to retract some stories and admit they are misrepresenting scientific data.
National Public Radio (NPR) published an article on its website last month claiming, “Ten years ago, a piece of ice the size of Rhode Island disintegrated and melted in the waters off Antarctica. Two other massive ice shelves along the Antarctic Peninsula had suffered similar fates a few years before. The events became poster children for the effects of global warming. … There’s no question that unusually warm air triggered the final demise of these huge chunks of ice.” (more…)

Twenty-year-old models which have suggested serious ice loss in the eastern Antarctic have been compared with reality for the first time – and found to be wrong, so much so that it now appears that no ice is being lost at all.
“Previous ocean models … have predicted temperatures and melt rates that are too high, suggesting a significant mass loss in this region that is actually not taking place,” says Tore Hattermann of the Norwegian Polar Institute, member of a team which has obtained two years’ worth of direct measurements below the massive Fimbul Ice Shelf in eastern Antarctica – the first ever to be taken.

Fraser, A.D., Massom, R.A., Michael, K.J., Galton-Fenzi, B.K. and Lieser, J.L. 2012. East Antarctic landfast sea ice distribution and variability, 2000-08. Journal of Climate 25: 1137-1156.
In the words of Frazer et al. (2012), “landfast sea ice (fast ice) is sea ice that is held stationary (fast) by being attached to coastal features (e.g., the shoreline, glacier tongues, and ice shelves), grounded icebergs, or grounded over shoals,” and that “it is a preeminent feature of the Antarctic coastal zone and an important interface between the ice sheet and pack ice/ocean.” They also state that variability in fast ice extent “is likely a sensitive indicator of climate change,” citing Murphy et al. (1995), Heil et al. (2006) and Mahoney et al. (2007); but they indicate that “despite the physical significance of fast ice, it is currently not represented in global climate circulation models or coupled ice-ocean-atmosphere models.” (more…)

The earth’s southern hemisphere is now in the winter season, and it is proving to be a severe one. There have been many deaths of people, animals, fish, and crops. But you haven’t heard about that from the northern hemisphere media.
As far as the media is concerned, there is no southern hemisphere. All the media coverage is about fires in Russia, Arctic ice melting, glaciers calving icebergs, heat waves on the U. S. east coast, and other “weather” occurrences up north. So let me bring you up to date on the highlights from down south. (more…)

It is said frequently that the climatic data for Antarctica for the past 30 years – the period for which records are far superior to previous times – shows clear signs of mankind’s influence. However, it is important to look at such changes in a historical context. This is important else we attribute any and every change seen in the past few decades to mankind alone. When it is done today’s changes are seen in a new light.
Antarctica’s climate has never been stable, and there have many significant changes in the past few thousand years, indeed the past few hundred as well. Proxy indicators from ice cores show abrupt alterations in atmospheric circulation and temperature. One of the most dramatic changes was the intensification of the circumpolar westerly winds between 6000 and 5000 years ago and between 1200 and 1000 years ago. (more…)

“Steepest slope ever.”
We have been hearing a lot about how the decline in Arctic ice is following the “steepest slope ever.” The point is largely meaningless, but we can have some fun with it. The Bremen Arctic/Antarctic maps are superimposed above, showing that ice in the Antarctic is at a record high and growing at the “steepest slope ever.” You will also note that most of the world’s sea ice is located in the Antarctic. But those are inconvenient truths when trying to frighten people into believing that “the polar ice caps are melting.”
There are several favorite lines of defense when trying to rationalize away the record Antarctic ice. (more…)

8 Mar 10 – “Almost all of the ice-covered regions of the Earth are melting – and seas are rising,” said Al Gore in an op-ed piece in the New York Times on February 27. Both parts of Gore’s statement are false. Never mind that Mr. Gore makes only passing reference to the IPCC’s fraudulent claims that the Himalayan glaciers will all melt by 2035. (“A flawed overestimate,” he explains.)
Never mind that Mr. Gore dismisses the IPCC’s fraudulent claims that the oceans are rising precipitously. (“Partly inaccurate,” he huffs.) Never mind that Mr. Gore completely ignores the admission by the CRU’s disgraced former director Phil Jones that global temperatures have essentially remained unchanged for the past 15 years. I’ll let someone else dissect Gore’s lawyering comments, and concentrate on just the one sentence about melting ice, because neither part of that sentence is true. Contrary to Gore’s assertions, almost all of the ice-covered regions of the Earth are growing, not melting – and the seas are not rising.
Let’s look at the facts. (more…)

In my last post, I pointed out a problem with the EPA’s major finding that:
Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG [greenhouse gas] concentrations.
I showed that it could be reasonably and straightforwardly argued that less than half of the warming since 1950 contained in the “observed” global temperature history can be attributed to anthropogenic greenhouse gas emissions. This is bad for the EPA, as this finding was simply parroted by the EPA from the IPCC Fourth Assessment Report (AR4)—a report relied on heavily by the EPA in underpinning its Endangerment Finding (that greenhouse gases released by human activities “threaten the public health and welfare of current and future generations.”). When the IPCC is wrong, so is the EPA. (more…)

The desperation of the climate extremists as global temperatures plummet for the tenth year in a row is growing. Stephen Schneider, professor of environmental biology and “global change” at Stanford University, said today:
- “We can no longer prevent global warming — it is upon us. Rapidly melting polar icecaps, acidification of the oceans, loss of coral reefs, longer droughts, more devastating wildfires, and sea level rise that threatens island nations and seacoasts everywhere are clear signs of change in Earth’s climate. Disruptions of the monsoon seasons in India and China already threaten crop yields resulting in more frequent and severe food shortages than in the recent past … If we continue ‘business as usual’ our habitat could be disrupted beyond recognition, with consequences for our way of life that we cannot now foresee. Without vigorous and immediate follow-up to the Copenhagen conference and well-conceived action we are all threatened by accelerating and irreversible changes to our planet.”
Nonsense. Here’s why. (more…)
