Comprehensive Study: Glacier Melt Estimates In Tropics Of South America OVERSTATED BY 10 TIMES! If you compare historical photos of glaciers with those taken more recently, you can see that where there was formerly ice there is now very often nothing but rock. Geographers, however, are less interested in the area covered by a glacier, and more interested in its mass. Researchers from FAU have now investigated all glacial areas in South America in more detail than ever before, from the tropical areas of Venezuela to the subpolar regions of Tierra del Fuego.
Their two major findings are that the highest rate of mass loss is in the Patagonian ice sheet, and that the glaciers in the tropics have lost considerably less mass than previously projected, although this is not the good news which it might appear at first sight. The researchers’ findings have been published in the journal Nature Climate Change. Surveying glaciers is nothing new. The other option is to take gravimetric measurements using satellites. One method for measuring all glaciers Entire glaciers have vanished. The Discovery Of Tree Trunks Under Glaciers 600 Meters Atop Today’s Treeline Date To The Last ICE AGE. By Kenneth Richard on 24. December 2018 Image Source: Ganyushkin et al., 2018 Between 60 and 40 thousand years ago, during the middle of the last glacial, atmospheric CO2 levels hovered around 200 ppm – half of today’s concentration.
Tree remains dated to this period have been discovered 600-700 meters atop the modern treeline in the Russian Altai mountains. This suggests surface air temperatures were between 2°C and 3°C warmer than today during this glacial period. Tree trunks dating to the Early Holocene (between 10.6 and 6.2 thousand years ago) have been found about 350 meters higher than the modern treeline edge. None of this paleoclimate treeline or temperature evidence correlates with a CO2-driven climate.

A stream flows through the toe of Kaskawulsh Glacier in Yukon’s Kluane National Park. In 2016, this channel allowed the glacier’s meltwater to drain in a different direction than normal, resulting in the Slims River’s water being rerouted to a different river system.
DANIEL SHUGAR The Weather Network (who do a decent job on local weather forecasting) are currently raving about Glaciers: You know climate change is getting serious when rivers are resorting to piracy. Canadian geomorphologist Dr. Daniel Shugar and his team headed to the Yukon last year to study changes in the flow of the Slims River, only to find out the river was gone. The Slims, which was fed by the Kaskawulsh glacier, has become the victim of the first case of what’s known as river piracy in modern recorded history. The team’s investigation soon turned up the culprit – the retreat of the Kaskawulsh Glacier, which has been retreating thanks to more than a century of climate warming. What Actually Happened FIG. 3. FIG. 1. Concurrent Warming and Cooling. Rannoch Moor, Scotland This post highlights recent interesting findings regarding past climate change in NH, Scotland in particular.
The purpose of the research was to better understand how glaciers could be retreating during the Younger Dryas Stadia (YDS), one of the coldest periods in our Holocene epoch. The lead researcher is Gordon Bromley, and the field work was done on site of the last ice fields on the highlands of Scotland. 14C dating was used to estimate time of glacial events such as vegetation colonizing these places. Bromely explains in article Shells found in Scotland rewrite our understanding of climate change at siliconrepublic. By analysing ancient shells found in Scotland, the team’s data challenges the idea that the period was an abrupt return to an ice age climate in the North Atlantic, by showing that the last glaciers there were actually decaying rapidly during that period.

Montana had a very cold, snowy winter last year, and this is what Glacier National Park Looks like today Glacier National Park Webcams – Glacier National Park (U.S. National Park Service) Scientists predicted Glacier National Park would be ice-free by 1948. 29 Dec 1923, Page 5 – at Newspapers.com That prediction failed, so they changed the date to 2002. 05 Mar 1952, Page 1 – The Post-Standard at Newspapers.com Then 2020.
No More Glaciers in Glacier National Park by 2020? Then 2044. Climate Change Threatens to Strip the Identity of Glacier National Park – The New York Times The game never ends, they just keep shifting the goal posts. Fifty Years Ago – National Geographic Said The Sun Controls Glacial Behavior. NYT Peddles More Global Warming Science Without Numbers. Recently, I noted the basic pattern of science reporting on global warming, particularly as practiced by The New York Times: feeding you an overall conclusion, illustrated with pretty pictures designed to make you feel like you’ve been given information—but withholding from you the real numbers you would need to actually evaluate and understand the issues.
I can’t overstate how important this is. There is no science without numbers. Science can’t get by on qualitative descriptions. If you say the average global temperature in 2016 was “higher” than in 2015, that’s not science. It could be a lot higher or a little higher. It could be a number that is enormous, or it could be a number that is literally insignificant. (And if they don’t tell you the number, guess which of those it is likely to be.) But reporters at The New York Times think you’re too dumb to understand that. Now they’re at it again. We can already suspect this is a long-term, natural decline. Climate Craziness of the Week: ‘feminist glaciology’ in the climate change context.
I’ll probably be labeled a misogynist pig for even bringing this paper to the attention of our readers, but there are just some things that just deserve to be called “crazy”. When I first saw this, I thought it might be a parody, or an old April Fools joke. Sadly, no. The abstract from this publication Progress in Human Geography reads: Glaciers, gender, and science: A feminist glaciology framework for global environmental change research Abstract Glaciers are key icons of climate change and global environmental change. Source: h/t to Richard Saumarez Like me, you are probably wondering what a “feminist glaciology framework” is Oh. The funding source didn’t surprise me: The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work is based upon work supported by the US National Science Foundation under grant #1253779.
Like this: Scientists find missing piece in glacier melt predictions. Stanford scientists have revealed the presence of water stored within a glacier in Greenland, where the rapidly changing ice sheet is a major contributor to the sea-level rise North America will experience in the next 100 years. This observation – which came out of a new way of looking at existing data – has been a missing component for models aiming to predict how melting glaciers will impact the planet. The group made the discovery looking at data intended to reveal the changing shape of Store Glacier in West Greenland. But graduate student Alexander Kendrick figured out that the same data could measure something much more difficult to observe: its capacity to store water. The resulting study, published in Geophysical Research Letters, presents evidence of glacier meltwater from the surface being stored within damaged, solid ice.
"All of our predictions of sea-level rise are missing this meltwater component," Schroeder said. A different perspective More information: Yasmina M. Alpine Glaciers Shrank Thousands Of Feet During NASA’s Coldest Years On Record. Himalayan Glacier Loss Is Due To Many Factors. Many news outlets have reported the very interesting finding detailed in Science Advances that ice loss from Himalayan glaciers has doubled in the past 40 years.
Using data from modern satellites and from declassified images taken by the US Hexagon series of spy satellites in the 1970s and 80s the researchers find that for 1975 – 2000 the mass loss was 4 billion tonnes per year increasing to 8 billion for 2000 – 2016. Some of these reports have responsibly said that Himalayan glacier ice-loss is due to many factors, others leave it implied that it is all due to man-made climate change. Changing patterns of monsoon precipitation (see here, here and here) together with the melting of glaciers, poses a significant threat to the freshwater supply to the densely populated regions downstream (see here, here and here) Poorly Understood Natural Variability As ever in science, and it’s especially true for climate change, things are somewhat more complicated than many reports indicate.
Global Cooling Causes Glaciers To Shrink. Glaciers shrunk thousands of feet in the late 19th century, as temperatures cooled towards NASA’s fake coldest years on record. The famous glaciers of the Rhone have shrunk several thousand feet in the Inst 20 years; considerably more than 100 ft a year. A number of the well-known glaciers are also shrinking at about the same rate, and the fact is established that these reminders of the great glacial period are certainly disappearing. 16 Aug 1902 – Alpine Glaciers Disappearing. – Trove Data.GISS: GISS Surface Temperature Analysis: Analysis Graphs and Plots NASA’s record cold also made the Northwest Passage open in 1904. TimesMachine: March 9, 1907. Ice sheets may melt rapidly in response to distant volcanoes – JunkScience.com. Claim: melting of glaciers on one side of the globe can trigger disintegration of glaciers on the other side of the globe. Claim: ‘temperature, not snowfall, driving tropical glacier size’, but Climategate emails suggest otherwise | Watts Up With That?
[UPDATE: and it’s not just Climategate email, see the analysis by McIntyre added below – Anthony ] From Dartmouth College and the irascible Lonnie Thompson of OSU, who still ‘publicly’ thinks in PR that Kilmanjaro and Peru’s Quelccaya glaciers are affected by temperature, not sublimation due to lack of precipitation. See below for the Climategate email that makes nonsense of the temperature claim made in the press release below. Also of note is Thompson’s claim that “PERUVIAN GLACIER MAY VANISH IN FIVE YEARS” made on February 15, 2007, and it was still there in 2012 by this photography.
Temperature, not snowfall, has been driving the fluctuating size of Peru’s Quelccaya Ice Cap, whose dramatic shrinkage in recent decades has made it a symbol for global climate change, a Dartmouth-led study shows. The study appears in the journal Geology. The research, which was funded by National Science Foundation, includes Dartmouth College, the University of Cincinnati and Penn State University. 5315.txt. Correlating CO2 And Glacial Cycles. Climate scientists acknowledge that CO2 follows rather than leads temperature, but they insist that feedback loops drive the transitions from glacial to interglacial conditions.
Glacial cycles and carbon dioxide: A conceptual model Let’s see if that makes any sense, by making a few observations. New Antarctic Ice Core Data Ice ages begin when CO2 is at a maximum. Ice ages end when CO2 is at a minimum. Both are the exact opposite of global warming theory.Sometimes temperatures rise quickly at 320 PPM CO2. Sometimes temperatures fall quickly at 320 PPM CO2Sometimes temperatures rise quickly at 200 PPM CO2. None of these observations are consistent with the idea that CO2 drives temperature. If CO2 was the temperature control knob, it would be impossible to either start or get out of an ice age. End of Ice: Voodoo Science Himalayan Glacier Crisis Rises from the Dead. Guest essay by Eric Worrall If you thought the “Voodoo Science” Himalayan glacier crisis died when its main backer, former IPCC head and alleged sex pest Rajendra Pachauri was forced to resign, think again; the glacier crisis is back.
A third of Himalayan ice cap doomed, finds reportEven radical climate change action won’t save glaciers, endangering 2 billion peopleAt least a third of the huge ice fields in Asia’s towering mountain chain are doomed to melt due to climate change, according to a landmark report, with serious consequences for almost 2 billion people.Even if carbon emissions are dramatically and rapidly cut and succeed in limiting global warming to 1.5C, 36% of the glaciers along in the Hindu Kush and Himalaya range will have gone by 2100.

IPCC Brand Science™ – extrapolating 10 himalayan glaciers to speak for 54,000 – meanwhile Himalayagate 2 is evolving over the Stern Report. The reports, presented at the UN climate change talks in Durban were brought together by the the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD). One three year study, funded by Sweden, found that of 10 glaciers measured in the region all are shrinking, with a marked acceleration in loss of ice between 2002 and 2005. “…funded by Sweden” Does anyone care to place any bets on WWF and/or Greenpeace involvement in this?
I’m sure Donna Leframboise will take a good look into this one. Meanwhile, here’s all the reason you need not to trust anything the IPCC says. This comment left on our open thread today from Roger Knights is about as growing into Himalayagate 2 as you can get: Three Strikes Against the IPCC’s Asia Group (By Roger Knights) (Summary: This post points out the cherry picking of quotations by the IPCC’s Asia group to spice up its widely publicized claim that 3/4 of a billion Asians were at risk of water shortages from glacier-melt.) Why? 1. (Errata) IPCC admits error on Himalayan glacier melt fiasco. But…there’s that word again, “robust” used in the context of error admission. Now all we need is an apology from Chairman Dr. Rajenda Pachauri for statements that claims that this error existed were “arrogant” and “voodoo science“. Will he give one? His track record suggests it is doubtful. UPDATE: It seems Dr. Angry Pachauri threatens to sue UK daily This is the best thing that could happen, as it will mean independent discovery.
IPCC statement on the melting of Himalayan glaciers1 The Synthesis Report, the concluding document of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (page 49) stated: “Climate change is expected to exacerbate current stresses on water resources from population growth and economic and land-use change, including urbanisation. This conclusion is robust, appropriate, and entirely consistent with the underlying science and the broader IPCC assessment.
