"In the relatively well-monitored Swiss Alps, however, Huss and his team managed to gather some 10,000 in situ observations that had been made over the past 100 years, and constructed three-dimensional computer models of 30 glaciers. By comparing a time series of daily melt, snow accumulation and ice and snow volume readings of the glaciers with a widely used index of the AMO [Atlantic Multidecadal Oscillation], they teased out the impact of natural climate variability. Although the mass balance of individual glaciers varied, the long-term overall trend followed the pulse of the AMO.....Natural climate variability is likely to have driven twentieth-century glacier shrinkage and thinning in other parts of the world, says Kaser. For example, his own research on the glaciers of Mount Kilimanjaro in Tanzania suggests that their dramatic recession is mainly due to multidecadal fluctuations in air moisture"

It continues to melt around the edges due to warmer ocean currents lapping at its edges, not because of a warmer atmosphere. Using satellite technology, expert scientist Scott Luthcke's research indicates that Greenland possibly has been melting at at a rate that represents only 0.005% to 0.008% of its volume.
What does this really mean? The ice sheet may take some 19,000 years to melt entirely. If the present global cooling trend continues, then it would take longer. ;-) (And scientists remain unconvinced that ice sheets would ever melt entirely based on most recent evidence.)
Putting it into perspective........
"So the next time you read something that breathlessly says.....“If this activity in northwest Greenland continues and really accelerates some of the major glaciers in the area — like the Humboldt Glacier and the Peterman Glacier — Greenland’s total ice loss could easily be increased by an additional 50 to 100 cubic kilometers (12 to 24 cubic miles) within a few years”.....you can say “Well, if it does increase by the larger estimate of 100 cubic km per year, and that’s a big if since the scientists are just guessing, that would increase the loss from 0.007% per year to around 0.010% per year, meaning that the Greenland Ice Cap would only last until May 23rd, 12010.”"
Read here. Global warming alarmists and associated IPCC scientists have made erroneous claims about glaciers worldwide. The basic claim is that glaciers are rapidly melting, adding to rising sea-levels because of human CO2-induced warming. As with almost all of these claims, they shrink to minor issues when proper scientific observation is finally applied.
"The five scientists report that "between 1962 and 2006, Alaskan glaciers lost 41.9 ± 8.6 km3 per year of water, and contributed 0.12 ± 0.02 mm per year to sea-level rise," which they note was 34% less than estimated by Arendt et al. (20002) and Meier and Dyurgerov (2002)...In addition to significantly revising what was previously believed about the magnitude of ice wastage in Alaska and northwest Canada in recent decades, Berthier et al. say their results suggest that "estimates of mass loss from glaciers and ice caps in other mountain regions could be subject to similar revisions," all of which would tend to mitigate against the rapidity with which the world's climate alarmists have long contended earth's mountain glaciers and ice caps were wasting away and thereby contributing to global sea level rise."
Read here. The idiocy of climate alarmist scientists knows now bounds. They will take the flimsiest of evidence, and for purely political reasons, publicize it as a major climate risk due to carbon dioxide emissions. Because mainstream media reporters and editors share the same political agenda as the climate scientists, headlines like this are created:
"Melting icebergs causing sea level rise"
Of course, that "sea level rise" is only 49 micrometers per year, as the scientists explain, which amounts to a 1 inch increase per 526 years. If climate alarmist scientists were not so desperate to politicize every nano-crumb of evidence into a world crisis, this type of information would barely make page 11 of National Enquirer, let alone major metropolitan dailies.
Memo to Judith Curry, the skeptics' favorite climate alarmist scientist: As this sea level rise story indicates, the politicization of climate science problem, and the harm done to true science, is not the result of Senator Inhofe, Marc Morano, and Rush Limbaugh. The original roots of the politicization of climate science, and its continuous maintenance, depends on such luminaries as: A. Gore, T. Wirth, Obama, J. Holdren, P. Erlich, M. Strong, Ted Turner, Paul "You're Treasonous" Krugman, Tom Friedman, P. Jones, B. Santer, Overpeck, M. Mann, K. Trenberth and a large cornucopia of others. If you don't understand the level of politicization expounded by such people, and their true objectives, then read what they have to say.
In the meantime, your political commentary regarding skeptics is ludicrous and self-serving. If you want the politicization to stop, hold your nose and go talk (complain) to your alarmist overlords.
Read here. U.S. government climate "experts" predicted that Arctic sea ice would melt to nothing because of the CO2-induced "unprecedented" (not) warming. As with almost all climate predictions emanating from U.S. climate scientists, nature is proving them wrong.
Why are U.S. climate scientists always so wrong? Are they just incredibly stupid? Nope, that's not the case - it's more venal than that. Simply put, their research funding (and salaries) provides the necessary incentive to mislead and lie about the global warming "crisis." Like all humans, scientists can be corrupted too.

Read here. Great article regarding the wild and irresponsible predictions by "experts" about the Arctic sea ice extent (or lack of) made over the last decade. Simply summarized, for political and funding reasons, scientists made claims about melting sea ice, based on models that were designed to predict melting sea ice in the first place -- it's a simple as that. No IPCC scientist or government expert predicted, nor any climate model, that the polar sea ice would actually expand as the chart below shows. Consensus "science" and climate models present a united front in documenting why both are worthless.
At the end of the article is a rationale, scientific explanation of what happened to cause the melting Arctic sea ice from a non-hysterical scientist, unlike those representing the IPCC and the NSIDC. (click on image to enlarge)
A few "expert" quotes from the article -
2007: "And Serreze, "concerned at the accelerated annual loss of Arctic ice", was predicting that the entire polar region, including the North Pole, could witness a total summer melt by 2030."
2007: "He and his team were offering "modelling studies" that indicated northern polar waters could be ice-free in summers within just 5-6 years, putting the complete disappearance of summer ice at 2013."
2008: "Serreze was back in the fray in June 2008, offering 50-50 odds that the North Pole would be ice-free that summer, "a first in recorded history", he claimed. And, even if it didn't happen that year, it was "just a matter of time"."
2008: "With predictions mounting that the 2008 melt could surpass the "extraordinary 2007 record low", in the August, Serreze was talking to Reuters, telling them that last year's record was blamed squarely on human-spurred climate change. "No matter where we stand at the end of the melt season it's just reinforcing this notion that Arctic ice is in its death spiral," said Serreze."
2009: "the NSIDC, this time in the form of Walt Meier, a research scientist, was saying that the Arctic Ocean "will" be effectively ice free sometime between 2020 and 2040, although it is possible it could happen as early as 2013."
2009: "another study was claiming that: "virtually all the sea ice in the Arctic will have melted during the summer months by 2037, and that it may even disappear as soon as the summer of 2020." The survey was carried out by scientists from the US National Oceanic and Atmospheric Administration (NOAA) and the University of Washington in Seattle "using the six most sensitive computer models of the Arctic region."
Read here. Two researchers review the Antarctica evidence from the last thirty years and come to conclusion that it's not going to be disappearing anytime soon.
"Over the course of the past three decades, Tedesco and Monaghan report that the continent-wide snow and ice melting trend was, in a word, "negligible." And they say that during the 2008-2009 austral summer, scientists from the City University of New York and the U.S. National Center for Atmospheric Research observed that snow and ice melt was, in a few more words, "a record low for the 30-year period between 1979 and 2009," or as they alternatively describe it, they say it was "a new historical minimum."
Read here. Based on satellite observations, the sea ice extant has been increasing at a rate close to 1% per year. Researchers speculate that ozone has caused increase but a climate model suggests growth is within natural climate variability. The CO2-AGW theory predicts that Antarctica should be warming and the sea ice pack should be shrinking.
"The only thing we can conclude at this point in time, therefore, is that for some still-unproven reason, and in spite of the supposedly unprecedented increases in mean global air temperature and CO2 concentration that the planet has experienced since the late 1970s, Antarctica sea ice extent has stubbornly continued to just keep on growing."
Read here. As Earth's climate has cycled through changes over the geological time, Greenland has faithfully recorded the changes. The glaciers and ice sheets responded accordingly, thus confirming that major climate change (including melting glaciers) will occur whether CO2 levels are low or high.
"Even in ice-cold Greenland, Holocene temperatures followed much the same temporal pattern
observed in other parts of the world, as did the advance and retreat
modes of its local glaciers, with maximum glacier extensions occurring
during the coldest period of the current interglacial (the Little Ice
Age). As a result, it was only to be expected that once the
millennial-scale oscillation of temperature bottomed out and began to
rise again, the result would be a significant warming and recession of
local glaciers, irrespective of anything the air's CO2 content might do..."
Read here. It's just not intuitive to think that a period of global cooling would result in a time of greater ice melt but that's exactly what happened during the 'cooling' 1950's, as peer research has now discovered. More recently, the global warming alarmists keep bemoaning the large 2007 ice melt, and predicting the warming will soon bring us ice-free Arctic waters. Interestingly, the recent greater ice melt has happened whilst the Earth cools. Why does cooling seem to cause Arctic melting? Future science research will hopefully explain.
And, we should note that there's a science truism that every politician, Hollywood celebrity, and mainstream press reporter/pundits should be forced to repeat 3 times prior to opening their mouths while their brain is disengaged: "The science is NEVER settled." Yes, a good dose of critical skepticism would save so many of these left/liberal types from the constant humiliation of moronism.
Read here. As the mainstream press has popularized, Earth's polar regions are supposed to warm and the sea ice area is supposed to shrink. Why? Because climate models predicted it, and reporters and pundits just accept 100% all climate model predictions, without a sliver of reservation. As with most other climate predictions though, over the last several decades the CO2-based climate models have been spectacularly wrong regarding the South Pole. Actual peer-reviewed research based on empirical evidence confirms this.
Read here. Earth's climate is constantly changing as it oscillates from one extreme to another. As the researchers documented, this oscillation also affects the Arctic area and its sea ice. During ancient periods, the earth was a lot warmer and produced periods where Arctic sea ice decline was substantial.
"Since the change in sea-ice cover observed at the end of the 20th century (which climate alarmists claim to be unnatural) was far exceeded by changes observed multiple times over the past several thousand years of relatively stable atmospheric CO2
concentrations (when values never strayed much below 250 ppm or much
above 275 ppm), there is no compelling reason to believe that the
increase in the air's CO2 content that has
occurred since the start of the Industrial Revolution has had anything
at all to do with the declining sea-ice cover of the recent past..."
Read here. From the "science is never, ever settled department," new peer-reviewed research does in depth study on glaciers' retreat and find it's due to enhanced solar radiation.
"Snow and ice melt was stronger in the 1940s than in recent years, in spite of significantly higher air temperatures in the present decade. An inner Alpine radiation record shows that in the 1940s global shortwave radiation over the summer months was 8% above the long-term average and significantly higher than today, favoring rapid glacier mass loss."
Read here, here and here. Arctic sea ice is affected by a number of powerful forces other than air temperatures. Although polar sea ice could have disappeared for short spans during the very warm summers in the past, the present Arctic sea ice condition remains quite large, even at its minimum during the summer months. For a historical perspective of the melting Arctic sea ice saga, this is an excellent piece. And despite the climate "expert predictions" that the South Pole sea ice would also soon disappear, since 1979 nothing could be further from the truth as 2009 was a record sea ice extent year.

Read here, here, and here. From the bowels of Climategate, we've learned of the corruption and treachery of a group of high level climate scientists. We also learned of their insufferable arrogance, which may be the ultimate climate forcing that has led to investigations for some. Often this arrogance is presented in terms of "consensus," when in reality there is no such thing in climate science. One of the supposed areas of "consensus" is in the field of glaciers - "there all melting and will soon disappear"! As the above linked articles indicate, the science of glaciers is in its infancy and it is dynamic. New discoveries are being made all the time, which keeps upsetting the current thinking.
Despite the new science that indicates glaciers aren't as in dire danger as hyped, the IPCC continues to insist that their old science is correct. It's not only the individual climate scientist that is arrogant.
Read here. As every climate alarmist and pundit states, and most journalists will blindly parrot, glaciers across the world are shrinking and disappearing because of human CO2-caused global warming and/or climate change, take your pick. Per usual, the alarmists and the MSM press are wrong, as not only the Russian glaciers show, but also the glaciers in Norway and Alaska.
Read here. Better equipment and better science finds that West Antarctic ice sheet is not melting nearly as fast as NASA was stating. Plus, the scientists confirmed the ice sheet has been melting over 20,000 years since the last ice age. Who would have thunk? Global warming "consensus" can be counted on to be non-settled science.
Read here. The MSM, and its major science reporters, has a long history of not even achieving a low level of objectivity and honesty in their global warming and climate change coverage. As an example of this low standard of reporting, a 2009 major climate condition has gone totally unreported (as of October 27, 2009) by the mainstream media - Antarctica is not melting - as global warming alarmists claim. Thank goodness though, the Revkin's of the world are reporting Arctic polar science in a much more complete and serious manner. For most citizens, this type of "reporting" by the press has become a joke, which has not reflected well on the major news outlets. (click image to enlarge)
Read here, here, here, here, and here. Climate alarmists and green organizations have fabricated stories about Himalayan glaciers melting due to human CO2 in order to raise contributors' donations. Like all other global warming and climate change hysterical claims, the actual science and truth point to culprits other than CO2.
Read here, here, here, here, and here. For all the CO2-causes-warming alarmist hysteria emanating from bureaucrats, politicians, the MSM and Hollywood celebrities about the Arctic, one would think climate researchers would have published numerous studies directly linking human-CO2 to Arctic warming/melting. Instead,.....
Read here. All the MSM hysteria about Greenland melting just does not jive with the scientific peer-researched studies. Global warming is not affecting southwest Greenland based on 220+ years of data. Like almost every previous study, this study confirmed that temperatures were warmer during the 1930's.
Read here and here. "Science" reporters have a penchant for reporting that Antarctic and Greenland ice sheets will soon collapse into oceans, resulting in flooded coastal areas and drowned islands. Experts say collapse is not only nonsense, it's impossible for for some very basic science reasons.
Read here and here. The usual suspects, AP and NYT, hype the Arctic global warming scare angle instead of discussing the actual history and science particulars. Plus, minimizing the advanced technology angle that makes the difficult possible.
Read here, here, here, here, here, and here. Multiple research efforts have determined that a combination of natural climate forces (Arctic Oscillation, North Atlantic Oscillation, Transpolar Drift Stream, cyclical flow of atmospheric energy around Arctic Circle) have created a warming environment in the Arctic area. The research also confirms that it has been warmer in the Arctic prior to this current period. Read here about 1944 ship journey via Northwest Passage. The image below is another testament to previous Arctic warming. (click to enlarge)
Read here. Reporter claims Greenland ice mass loss is over 300 gigatonnes per year, when it's actually been trending about 12 gigatonnes/year. Of course, if he was correct, there would have been a noticeable world sea level rise but that has not happened. And, the fact that Antarctic ice mass growth offsets Greenland's loss is conveniently glossed over.
Read here. Couple this with Greenpeace admission that "Arctic ice would disappear by 2030" was a "mistake" (an exaggeration of a speculative prediction), plus the news that polar bears are prospering this summer, and it really becomes obvious: global warming alarmists have no clue what they speak of and any prediction coming from their mouths should be ignored.
Synopsis: Human CO2 not the cause of glaciers melting - glaciers melted before human CO2.
Source here. "Glaciers around the world are continuously advancing and retreating, with a general pattern of retreat since the end of the Little Ice Age. There is no evidence of a increased rate of melting overall since CO2 levels rose above their pre-industrial levels, suggesting CO2 is not responsible for glaciers melting."
For years (decades?), climate alarmist scientists have been claiming
oceans were rising with "unprecedented" speed due to human-caused
global warming. These scientists claim that because of all the melting
sheets, due to human-caused warming, the sea levels are rising
at an accelerated pace and
will continue to so - up to a 20 foot rise by the end of the century is
predicted. If this accelerated sea level rising is happening as
claimed, then it should be evident across the world. Fortunately, the
sea rise at Maloy, Norway is averaging about a third of a foot per century. This is just but one
example of ocean facts countering sea-rise
alarmism hype - more to follow. (On average, recent satellite
measurements put global ocean level increases at 3mm/year or 1
