Glaciers Growing Again
Did the CO2 levels drastically drop and I missed the news? Or does this match up with solar cycle activity? Explain to me so I can understand how increasingly higher and higher levels of CO2 resulted in glacier growth instead of increasingly faster melt-offs.

Looks to me like the CO2 theorists have a major contradiction on their hands.


Glaciers in Norway Growing Again


Scandinavian nation reverses trend, mirrors results in Alaska, elsewhere.

After years of decline, glaciers in Norway are again growing, reports the Norwegian Water Resources and Energy Directorate (NVE). The actual magnitude of the growth, which appears to have begun over the last two years, has not yet been quantified, says NVE Senior Engineer Hallgeir Elvehøy.

The flow rate of many glaciers has also declined. Glacier flow ultimately acts to reduce accumulation, as the ice moves to lower, warmer elevations. The original trend had been fairly rapid decline since the year 2000. The developments were originally reported by the Norwegian Broadcasting Corporation (NRK).

DailyTech has previously reported on the growth in Alaskan glaciers, reversing a 250-year trend of loss. Some glaciers in Canada, California, and New Zealand are also growing, as the result of both colder temperatures and increased snowfall.

Alaskan Glaciers Grow for First Time in 250 years


A bitterly cold Alaskan summer has had surprising results. For the first time in the area's recorded history, area glaciers have begun to expand, rather than shrink. Summer temperatures, which were some 3 degrees below average, allowed record levels of winter snow to remain much longer, leading to the increase in glacial mass.

"In mid-June, I was surprised to see snow still at sea level in Prince William Sound", said glaciologist Bruce Molnia. "In general, the weather this summer was the worst I have seen in at least 20 years".

"On the Juneau Icefield, there was still 20 feet of new snow on the surface late July. At Bering Glacier, a landslide I am studying not become snow free until early August." Molnia, who works for the US Geological Survey, said it's been a "long time" since area glaciers have seen a positive mass balance -- an increase in the total amount of ice they contain.

Since 1946, the USGS has maintained a research project measuring the state of Alaskan glaciers. This year saw records broken for most snow buildup. It was also the first time since any records began being that the glaciers did not shrink during the summer months.

50. The Tibetan glaciers may be suffering the same problems as the Andean and Kilimanjaro glaciers
I.E., localized deforestation. In pre-industrial times, water vapor evaporating from the rainforests (which can release just as much H2O as the oceans at times) was swept upslope where it fell as snow and replenished the glaciers on Kilimanjaro and in the Andes year round. Removal of those forests has stopped that mechanism, which now limits snowfall. Glaciers aren't static and require a large amount of new snow every year just to remain stable.

I was reading a paper recently on the Tibetan glaciers which pointed to the same issue. The northerly summer monsoon sweeps across India from the Arabian sea and drops massive amounts of rain onto the Indian subcontinent. Only 100 years ago more than 40% of India was covered in that rainforest, permitting massive amounts of water to radiate back into the atmosphere. Much of that vapor went north, where it fell onto the Himalayas as snow.

Today only 8% of India is covered in forest, and most of that is concentrated in extreme eastern India where it does little to help the Himalayan snowfall numbers. The rest of the forest, including virtually all of the native forest on the subcontinent, has been cleared for farms and cities.

Even if global warming were stopped and reversed today, these glaciers would still melt away.

35. Since becoming hysterically, obsessively concerned about the GW, we have
been using the new kind of light bulbs (replaced the first one we had installed 6 months ago, the date I had written on it was 2004. Been turning the lights off and using little electricity around the house. Hoping maybe we have had an effect enough to give us a bit of extra time to really turn things around.

54. He is snarking you because it is unlikely that we have even reached the climax
of the impact from the pollution from the 50's through the 70's regarding glacial impact.

He is "concerned" that you think it is possible to positively impact GW and glacier growth/demise by the recent and relatively minor changes that have been made regarding energy consumption.

53. was reading yesterday that you could put modern filters on all the coal plants in the world
And you would save 2-3 times what you could save if the whole world stops driving. Too bad a lot of states don't require these filters. NC is currently sueing Tennessee to force their coal plants on the borders to use the new technology.

They are causing a tremendous amount of pollution in Asheville, and western NC.

5. At least as far as Alaska is concerned,
Edited on Sun Nov-30-08 01:43 PM by Blue_In_AK
we've been told that we're in a period of "Pacific decadal oscillation," http://jisao.washington.edu/pdo/ which I think has something to do with how the earth is tilted on its axis, and that we should expect perhaps up to 40 years of cooler weather than we've experienced in the past few decades. I also read that our cooler summer (which was pretty miserable really) and ocean temperatures helped bring the fish back off the coasts of Oregon and Washington. If we here in Alaska have to suffer through gray, rainy, cold summers to restore the balance of nature, I'm okay with it, although I was kind of liking that global warming thing while it lasted. :)

Precipitation patterns may change, wind and ocean currents may change... a lot will happen besides warming.

51. They are equally accurate
What causes the Climate Change? That would be the increased heat captured in the modified alberio. So which came first or did they come together (heat capture vs. climate change)?

So why is one more accurate than the other? It's like calling it a car crash or was it a collision?

And too, modest ice accumulation in a few spots on the globe is at this time statistically insignificant.

9. The best explanation I could give would be that
there's a difference between local warming and global climate change. In other words, some areas of the entire system can sometimes buck the overall trend.

Another thing to consider is that fluctuations do not necessarily mean that there is not a trend. As an analogy, someone can be losing weight over the course of a year, but still have days where they gain a pound or two.

56. This is the Infamous North Atlantic Oscillation
A possible occurrence but some models that I have seen actually predict a warming to override the effect of the thermocline modulation. Clouds (jet contrails) may have another wild card that is still not fully predicted.

13. Local conditions fluctuate with local weather patterns.
A cold summer in Alaska or a warm winter in Boston or a busy hurricane season in the Gulf of Mexico do not prove or disprove anything.

You have to take a look at what's happening world-wide over decades to really be able to say anything. I'm sure this won't stop the denialists from citing this as "proof" that global warming is a hoax, however.

By the way, why would you think this says anything about the cause of global warming? And why do you use the expression "CO2 Theorists"? I think I smell an agenda... My apologies if I am wrong.

14. I'm not a climatologist but
but I do have some formal education in thermodynamics and planetary atmospheres.

So glacier mass has built in some places again? I'd like to see better evidence, but not surprising, really. An average rise in global temperature of, say, 0.9 degrees C represents a huge addition of heat to the global system. (Kinda like heating a swimming pool ... takes a lot of power to raise water temperatute by 1 degree.) But average figures tell us nothing about have that energy transfers within the system. That requires detailed measurement and analysis.

As the energy of the system rises, the modes of energy transfer between its components will change. For example, polar ice melts, allowing more of that energy to go into raising water temperates in the arctic and freshening North Atlantic sea water. As salinity drops and additional, ocean currents may be expected to shift in course, speed, depth, etc. Ocean currents are major conveyors of heat energy so these shifts can be expected to have effects on local weather. Thus raising the average temperature of the planet can cause increases in snow accumulations in some regions, at least for a while.

A look at the data suggests disturbing (if you are invested in high energy technology civilization) shifts in the energy transfer mechanism of the atmosphere and oceans. It is difficult to predict exactly how these will work out and what the new equilibrium will look like. Part of the problem with that is the vast array of positive feedback mechanisms that warming has triggered. There are those (and I tend to believe them) that think the effect of the postive feedback now represents a bigger "signal" to the system than human the effects of human activity. In short, the global warming deniers have succeeded in stringing things out until the opportunity for preventative action has passed.

Congrats, guys.

Unfortunately for most of us, we won't enjoy the outcome, nor the unknown number of transitions we will experience before a new equilibrium is achieved. As the climate changes, there will be "winners and losers". Places we like will and have invested in will become inhospitable, and places previously undersireable will become prime real estate. Food supplies will become increasingly strained. The geopolitical and strategic implications of all this are difficult to predict, but it is likely that the pressures that produce conflict are going to increase. So in addition to weird weather, rapid changes in climate that stress infrastructure (especially with regard to water supplies) , and increasing presssure on people to move across defined boarders, we are likely to see more wars.

Hey, but what the hell. We made a fast buck off old technology. We could have done better for future generations but screw 'em. We had a good time and lived high on the hog. No worries, mate.

Lockwood, Mike and Fröhlich, Claus (2007) Recent oppositely directed trends in solar climate forcings and the global mean surface air temperature. Proceedings of the Royal Society A, 463, (2086), 2447-2460.

Abstract

There is considerable evidence for solar influence on the Earth’s pre-industrial climate
and the Sun may well have been a factor in post-industrial climate change in the first half
of the last century. Here we show that over the past 20 years, all the trends in the Sun
that could have had an influence on the Earth’s climate have been in the opposite
direction to that required to explain the observed rise in global mean temperatures.

16. Depending on greenhouse gases, we may end the ice ages or trigger the next one
A open Arctic Ocean is consistent with increased precipitation in Alaska, Canada, Greenland, Scandinavia and Siberia. This causes cool summers over the northern continental land mass, incomplete melting of the snowfall, and increased glaciation.

So melting of the Arctic Ocean ice would normally trigger the next Ice Age, with the consequent regrowth of the North American, European and Siberian ice sheets.

This continues until the sea levels go down, northward currents from the Atlantic to the Artic diminish, and the Arctic Ocean freeze over.

On the other hand, if we have put enough greenhouse gases into the atmosphere, the atmospheric warming may prevent the ice shields from forming and we will go back to a climate similar to before the ice ages began about 6 million years ago.

22. Out of 32 Norwegian glaciers measured, 3 grew; 24 shrunk
Edited on Sun Nov-30-08 03:45 PM by muriel_volestrangler
Which tells us a lot about how 'Daily Tech' is willing to distort things to get their agenda across.

Here's the Norwegian page they've linked to: http://www.nrk.no/nyheter/1.6322673

And here's the results of Google translation:

Senioringeniør Hallgeir Elvehøy in the Norwegian Water Resources and Energy Directorate (NVE) said that the NTB in a note to the message that brefronten in 22 of 32 surveyed glaciers in Norway have pulled back in the past year.

- If pålagringen of snow on the glaciers continues, the withdrawal stop or brefrontene again move forward, "said Elvehøy.
He said that NVE is not yet done the calculations that will tell how much the glaciers that glacier, ski and Svartisen added on the last two years. But it is clear that this development does not apply in Jotunheimen glaciers, and in northern Norway no other glaciers than Svartisen.

Better translation will be appreciated, of course, but luckily the people at NVE write their web pages in English too:

Results 2008

Thirty-two glaciers were measured in 2008, eight glaciers in North-Norway, and twenty-four glaciers in South-Norway. Twenty-four glaciers retreated.

Fåbergstølsbreen in Jostedalen in Luster retreated 60 meters, and Brenndalsbreen in Stryn retreated 56 meters. Bondhusbrea, a western outlet from Folgefonna ice cap in Kvinherad retreated 50 meters. At three glaciers the measurements indicated advance. This is partly adjustments to relatively large changes last year. Five glaciers had only minor changes (+/- 2 meters). Mean annual length change was 14 meters. Measurements were resumed at three glaciers - Tunsbergdalsbreen in Jostedalen which was monitored between 1900 and 1965, and Trollkyrkjebreen (measured 1944 - 1974) and Finnanbreen (measured 1950-1974) at Trollstigen in Møre & Romsdal.

23. West Antarctic Glaciers Melting At 20 Times Former Rate, Rock Analysis Shows
http://www.sciencedaily.com/releases/2008/02/080229075228.htm

Boulders the size footballs could help scientists predict the West Antarctic Ice Sheet's (WAIS) contribution to sea-level rise according to new research.

Scientists from British Antarctic Survey (BAS), Durham University and Germany's Alfred Wegener Institute for Polar and Marine Research (AWI) collected boulders deposited by three glaciers in the Amundsen Sea Embayment -- a region currently the focus of intense international scientific attention because it is changing faster than anywhere else on the WAIS and it has the potential to raise sea-level by around 1.5 metres.

Analysis of the boulders has enabled the scientists to start constructing a long-term picture of glacier behaviour in the region. An urgent task is to put recent ice sheet changes into a historical context, and determine if these are part of a natural retreat since the end of the last glacial period (about 20 thousands years ago), or if they are a result of recent human-induced climate change.

Lead author Dr Joanne Johnson of BAS says, "Until now we didn't know much about the long-term history of this part of the West Antarctic Ice Sheet because the region is incredibly remote and inaccessible. Our geological findings add a new piece to the jigsaw and will be used for improving computer models -- the most important tools we have for predicting future change."

24. Antarctic Glaciers Melting Rapidly
http://www.livescience.com/environment/050421_glacial_retreat.html

A new study of glaciers in a portion of the Antarctic finds 84 percent of them have retreated over the past 50 years in response to a warmer climate.

The work was based on 2,000 aerial photos, some taken in the 1940s, and satellite images. The climate in the region has warmed by more than 4.5 degrees Fahrenheit (2.5 Celsius) in the last 50 years, the scientists said.

"The widespread retreat of the glaciers on the Antarctic Peninsula over the last 50 years was largely caused by climate change," said David Vaughan of the British Antarctic Survey in Cambridge. "Are humans responsible? We can't say for sure, but we are one step closer to answering this important question."

The findings mirror similar changes seen in other parts of the Antarctic and in the Arctic, too.

25. In regards to CO2 historically...
I don't know about recently, but large and I mean LARGE influxes of CO2 (and other gases like SO2, sulfur dioxide) into the atmosphere are usually the result of a massive volcanic eruption. The result is an influx of CO2 into the atmosphere which works to refract light on a global level causing seasonal planetary cooling. Depending on the size of the eruption, it could last for a couple of months or a few years. Supervolcano explosions could cause it to last a century or more. I'll give an example below of an eruption that caused such world cooling, the most present one that I can remember... Krakatoa, 1883.

26. Glaciers in southern Alps shrinking at alarming rate (New Zealand)
http://economictimes.indiatimes.com/Earth/Global_Warming/Glaciers_in_southern_Alps_shrinking_at_alarming_rate/rssarticleshow/3493349.cms

Glaciers in the southern Alps have lost 2.2 billion tonnes of permanent ice in a year since April 2007, the fourth highest annual loss since monitoring began.

For the past 32 years, the New Zealand based National Institute of Water & Atmospheric Research (NIWA) has been surveying 50 glaciers in the southern Alps, using a small fixed wing aircraft, to record the height of the snow line at the end of summer

NIWA principal scientist Jim Salinger said photographs taken on this year's survey showed the glaciers had lost much more ice than they had gained during the past glacier year, reports Sciencealert.com.

"As a result of La Niña conditions over New Zealand, more easterlies, and warmer than normal temperatures, there was less snowfall in the southern Alps and more snowmelt.

27. Melting Swiss Glaciers Threaten Alps
http://www.planetark.com/dailynewsstory.cfm/newsid/28158/story.htm

Hot summers in the 1990s in particular, prompted a glacier melt-down which has outpaced previous forecasts. It could impact tourism and cause more environmental hazards such as flash floods, scientist Frank Paul said.

"It is amazing what huge masses of ice have been lost," he told Reuters in a telephone interview. "Every hiker in the Alps knows about it: the changes in recent years have been dramatic."

While Swiss glaciers shrank a meager one percent in the 12 years to 1985, they lost some 18 percent of their area in the 1985-2000 period, the research showed.

This suggests they are melting faster than earlier estimates which put the loss at 30 percent between 1980 and 2025.

http://query.nytimes.com/gst/fullpage.html?res=9805E3DA1039F937A15752C1A9649C8B63

From the top of this snow-capped peak 17,400 feet up, the surrounding Royal Range looks as healthy as ever: deep, glittering snow and a thick covering of glaciers as far as the eye can see.

But as Eulalio Gonzales, a veteran mountain guide, surveyed from the craggy peak overlooking Bolivia's windswept highlands, all he saw were remnants, fading and shrinking fast.

This mountain's glacier, boasting the world's highest ski slope, has been melting so steadily that scientists predict its demise in a decade. The Zongo glacier on the nearby mountain of Huayna Potosi is retreating by 10 yards a year.

On a third peak, the 18,000-foot Condoriri, the glacier that supplies the largest reservoir in the Bolivian highlands is shriveling so fast that scientists fear a scarcity of drinking water in the decades to come.

30. Didn't you get spanked enough in your Global Warming Swindle post?..
At least your idiotic series of climate change denial posts gives more posters the opportunity to laugh at you.

33. Africa's glaciers gone by 2025 - American Geophysical Union
http://news.mongabay.com/2006/0515-agu.html

Fabled equatorial icecaps will disappear within two decades, because of global warming, a study British and Ugandan scientists has found. In a paper to be published 17 May in Geophysical Research Letters, they report results from the first survey in a decade of glaciers in the Rwenzori Mountains of East Africa. An increase in air temperature over the last four decades has contributed to a substantial reduction in glacial cover, they say.


The Rwenzori Mountains--also known as the Mountains of the Moon--straddle the border between the Democratic Republic of Congo and the Republic of Uganda. They are home to one of four remaining tropical ice fields outside of the Andes and are renowned for their spectacular and rare flora and fauna. The mountains' legendary status was set during the second century, when the Greek geographer Ptolemy made a seemingly preposterous but ultimately accurate statement about snow-capped mountains at the equator in Africa: "The Mountains of the Moon whose snows feed the lakes, sources of the Nile."

The glaciers were first surveyed a century ago when glacial cover over the entire range was estimated to be 6.5 square kilometers <2.5 square miles>. Recent field surveys and satellite mapping of glaciers conducted by researchers from University College London, Uganda's Makerere University, and the Ugandan Water Resources Management Department show that some glaciers are receding tens of metres each year and that the area covered by glaciers halved between 1987 and 2003. With less than one square kilometer of glacier ice remaining, the researchers expect these glaciers to disappear within the next twenty years.

Richard Taylor of the University College London Department of Geography, who led the study, says: "Recession of these tropical glaciers sends an unambiguous message of a changing climate in this region of the tropics. Considerable scientific debate exists, however, as to whether changes in temperature or precipitation are responsible for the shrinking of glaciers in the East African Highlands that also include Kilimanjaro and Mount Kenya." Taylor and his colleagues found that in the Rwenzori Mountains since the 1960s, there are clear trends toward increased air temperature without significant changes in precipitation.

34. Western Canada's Glaciers Hit 7000-Year Low
http://www.sciencedaily.com/releases/2007/10/071030092705.htm

Tree stumps at the feet of Western Canadian glaciers are providing new insights into the accelerated rates at which the rivers of ice have been shrinking due to human-aided global warming.

Geologist Johannes Koch of The College of Wooster found the deceptively fresh and intact tree stumps beside the retreating glaciers of Garibaldi Provincial Park, about 40 miles (60 km) north of Vancouver, British Columbia. What he wanted to know was how long ago the glaciers made their first forays into a long-lost forest to kill the trees and bury them under ice.

To find out, Koch radiocarbon-dated wood from the stumps to see how long they have been in cold storage. The result was a surprising 7000 years.
"The stumps were in very good condition sometimes with bark preserved," said Koch, who conducted the work as part of his doctoral thesis at Simon Fraser University in Burnaby, British Columbia. Koch will present his results on Wednesday, 31 October 2007, at the Geological Society of America Annual Meeting in Denver.

Don't think for a second that global warming has been solved.

some grow, some shrink
nature seeks to balance disruptions

global warming could indeed trigger an ice age

globally though, ice is still shrinking

44. There are trends within trends, of course.
If there is a major global warming trend caused by CO2, there will still be trends within that larger trend, just as there are cold days in the summer and warm days in the winter.

Going back a millenium to the great medieval warming trend, there were still years that were colder than average, and years that were hotter, but overall the warming trend raised the climate's temperature overall.

Just as I argued against increased hurricane activity over the last few years proving global warming, I'll argue against short-term glacial activity as disproving it. The scientific models account for all this. Any argument over whether man-made GW is happening needs to concentrate on the science, not on anecdotes.

63. It is something intrinsic to the Bushie-Nazi mentality. They LOVE lying and spying.
Let's say an inordinate love of those things.

And, though I have no idea about the OP and would not venture a guess, some Bushies have, yes, posted thousands of posts and then ripped their mask off.

Silverhair (I think that was his name, it was quite awhile ago) strikes me as one, but he never hid his Bushie asshollery very well. I always suspected him.

But he was one Bushie who REALLY loved lying and spying. He did post thousands of posts, and even though he wasn't very good at hiding his asshollery, he did fool a lot of people.

Anyway my point is that such things have happened before, though I mak no speculations about the OP, as I have not read enough of his posts (or any of them, before this one).
