AP journo in wonderland

What planet is this AP journo living on?

“The European Space Agency is launching a satellite that scientists hope will help them pin down the effects of global warming on the Earth’s ice packs more precisely.

The CryoSat 2 mission, which starts Thursday after years of delays, will be able to pinpoint details of changes in polar ice so scientists can better understand the alarming picture of the world’s retreating ice caps.  …

For coastal cities and islands, the information may be a question of survival.

If all of the Earth’s polar ice and glaciers were to melt, sea levels could rise up to 230 feet (70 meters), Miller said.

If only Greenland became ice-free, it would mean a 21.33-foot (6.5-meter) rise, he said.”  “EU satellite to check climate change impact on ice

Meanwhile, on planet Earth, arctic sea ice is at its 30-year average, antarctic sea ice continues to grow, and:

“The extent of sea ice over the Arctic Ocean grew until the last day of March, the latest the annual melting season has begun in 31 years of satellite records, the U.S. National Snow and Ice Data Center said.”  “Arctic Sea Ice Melting Season Posts Latest Start on Record

Antarctic sea ice gate

02/17/2010

“And just in case further evidence is needed, [a] recent 2009 paper by Turner et al. (on which Comiso was a co-author), concluded that:

Based on a new analysis of passive microwave satellite data, we demonstrate that the annual mean extent of Antarctic sea ice has increased at a statistically significant rate of 0.97% dec-1 since the late 1970s.

This rate of increase is nearly twice as great as the value given in the [UN IPCC’s] AR4 (from its non-peer-reviewed source).

So, the peer reviewed literature, both extant at the time of the AR4 as well as published since the release of the AR4, shows that there has been a significant increase in the extent of sea ice around Antarctica since the time of the first satellite observations observed in the late 1970s. And yet the AR4 somehow “assessed” the evidence and determined not only that the increase was only half the rate established in the peer-reviewed literature, but also that it was statistically insignificant as well. And thus, the increase in sea ice in the Antarctic was downplayed in preference to highlighting the observed decline in sea ice in the Arctic.

It is little wonder why, considering that the AR4 found that “Sea ice is projected to shrink in both the Arctic and Antarctic under all SRES scenarios.””  “Another IPCC error:  antarctic sea ice increase underestimated by 50%

"Rotten" ice again

01/21/2010

What do you do when arctic sea ice increases, contrary to AGW dogma?  Why say the ice is “rotten” of course:

In early September 2009, satellite measurements implied that most of the ice in the Beaufort Sea either was thick ice that had been there for multiple years or was thick, first-year ice.

However, in situ observations made in September 2009 by Barber et al. show that much of the ice was in fact “rotten” ice — ice that is thinner, heavily decayed, and structurally weak due to a uniform temperature throughout.

The authors suggest that satellite measurements were confused because both types of ice exhibit similar temperature and salinity profiles near their surfaces and a similar amount of open water between flows. The authors note that while an increase in summer minimum ice extent in the past 2 years could give the impression that Arctic ice is recovering, these new results show that multiyear ice in fact is still declining.  Ice is ‘rotten’ in the Beaufort Sea

““While sea ice melts away and the oceans warm, the Obama administration is frozen in inaction. Instead of protecting penguins and taking meaningful steps to address global warming,” said Shaye Wolf, a biologist with the Center for Biological Diversity, “our government is dragging its feet while penguins are marching toward extinction.“”  “Suit to Be Filed Over Delay in Protection for Penguins Hurt by Climate Change and Industrial Fisheries

More alarmist crap from AP

The ice melt across Antarctica during the antarctic summer (October-January) of 2008-2009 was the lowest ever recorded in the satellite history, ice is expanding on the continent, and antarctic sea ice continues its 30-year growth trend. How ignorant can this journo be?

“Hoping to better understand how a melting Antarctica could swamp the planet, a NASA plane outfitted with lasers and ground-penetrating radar made its first flight over the icy continent on Friday.

The DC-8 left Punta Arenas, Chile, on a mission to fly as low as 1,000 feet (300 meters) over Antarctica. Like the NASA satellite that has provided shocking data on how quickly Antarctic ice is disappearing, this plane will measure snow cover and ice thickness. But it also has equipment that will enable scientists to see under the ice shelves, measuring the water below.

The goal is to understand just how warm ocean currents may be pulling the ice sheets seaward, melting their undersides. These ice sheets are rapidly collapsing — as fast as nine meters (27 feet) a year according to a study published in the journal Nature last month. If they disappear, far greater ice masses that lie on Antarctic bedrock could then melt into the sea, submerging coastal communities around the globe.” “NASA flies over Antarctica to measure icemelt

Ice is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap. …

Antarctica has 90 per cent of the Earth’s ice and 80 per cent of its fresh water. Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica [primarily the antarctic peninsula]. …

However, the picture is very different in east Antarctica …

East Antarctica is four times the size of west Antarctica and parts of it are cooling. The Scientific Committee on Antarctic Research report prepared for last week’s meeting of Antarctic Treaty nations in Washington noted the South Pole had shown “significant cooling in recent decades“.

Australian Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica. …

Ice core drilling in the fast ice off Australia’s Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Centre shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years. The average thickness of the ice at Davis since the 1950s is 1.67m.

A paper to be published soon by the British Antarctic Survey in the journal Geophysical Research Letters is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded.” “Revealed: Antarctic ice growing, not shrinking
