Those expanding ones must be some more who got their AGW exclusion permits

Geneva, 25Feb09
(AP) Glaciers in Antarctica are melting faster and across a much wider area than previously thought, a development that threatens to raise sea levels worldwide and force millions of people to flee low-lying areas, scientists said Wednesday.
Researchers once believed that the melting was limited to the Antarctic Peninsula, a narrow tongue of land pointing toward South America. But satellite data and automated weather stations now indicate it is more widespread.
The melting also extends all the way down to what is called west Antarctica, said Colin Summerhayes, executive director of the Britain-based Scientific Committee on Antarctic Research.
That's unusual and unexpected, he told The Associated Press in an interview.
By the end of the century, the accelerated melting could cause sea levels to climb by 3 to 5 feet - levels substantially higher than predicted by a major scientific group just two years ago.
Making matters worse, scientists said, the ice shelves that hold the glaciers back from the sea are also weakening.
The report Wednesday from Geneva was a broad summary of two years of research by scientists from 60 countries. Some of the findings were released in earlier reports.

No, that is the preliminary discussions with the press from this group of scientists;
IPY 2007-2008
The papers will be published later in peer reviewed journals, and are the evidence collected is already being reported on in such meetings as the AGU's fall meeting in 2008.
Hey what do you know? They haven't exactly been monitoring but they found volcanic activity.
hmmm, turn stove on water gets hot....

This map of the Arctic Ocean shows the Gakkel Ridge, Nansen Basin, Lomononsov Ridge, and the proposed cruise track of the icebreaker Oden. Credit: Jack Cook/WHOI. New evidence deep beneath the Arctic ice suggests a series of underwater volcanoes have erupted in violent explosions in the past decade.
Hidden 2.5 miles (4,000 meters) beneath the Arctic surface, the volcanoes are up to a mile (2,000 meters) in diameter and a few hundred yards tall. They formed along the Gakkel Ridge, a lengthy crack in the ocean crust where two rocky plates are spreading apart, pulling new melted rock to the surface.

From the same article;
With news this week that polar ice is melting dramatically, underwater Arctic pyrotechnics might seem like a logical smoking gun. Scientists don't see any significant connection, however.
"We don't believe the volcanoes had much effect on the overlying ice," Reeves-Sohn told LiveScience, "but they seem to have had a major impact on the overlying water column."
The eruptions discharge large amounts of carbon dioxide, helium, trace metals and heat into the water over long distances, he said.
The research, detailed in the June 26 issue of the journal Nature, was funded by NASA, the National Science Foundation and WHOI.
Would Senate testimony by an MIT professor be helpful?

Some say it because of soot. That would explain China. You don't burn dirty coal do ya?
Why are other glaciers expanding? That seems to fly against AGW being the cause, heh?
Nice try, but all the glaciers are melting except for a few in Norway.
Why is Venus hotter than Mercury?
mercury has no atmosphere.
are you auditioning for "are you smarter than a 5th grader"?
good luck.

Well, you are half right.
Because Venus has an atmosphere that is mostly CO2.
So even though Venus receives 25% of the heat from the sun that Mercury does, Venus is hotter.
Venus has an extremely dense atmosphere, which consists mainly of carbon dioxide and a small amount of nitrogen. The atmospheric mass is 93 times that of Earth's atmosphere while the pressure at the planet's surface is about 92 times that at Earth's surfacea pressure equivalent to that at a depth of nearly 1 kilometer under Earth's oceans. The density at the surface is 65 kg/m³ (6.5% that of water). The enormously CO2-rich atmosphere, along with thick clouds of sulfur dioxide, generates the strongest greenhouse effect in the solar system, creating surface temperatures of over 460 °C.[22] This makes Venus's surface hotter than Mercury's which has a minimum surface temperature of -220 °C and maximum surface temperature of 420 °C, even though Venus is nearly twice Mercury's distance from the Sun and receives only 25% of Mercury's solar irradiance. Because of the lack of any moisture on Venus, there is almost no relative humidity (no more than 1%) on the surface, creating a heat index of 450 °C to 480 °C.
Studies have suggested that several billion years ago Venus's atmosphere was much more like Earth's than it is now, and that there were probably substantial quantities of liquid water on the surface, but a runaway greenhouse effect was caused by the evaporation of that original water, which generated a critical level of greenhouse gases in its atmosphere.[23

That's not even true. Data @ NASA GISS: Surface Temperature Analysis: August 2007 Update and EffectsFurther the ground temperature is "adjusted" with no explanation of why or what the adjustments are or how they were arrived at.
