The glacier has lost about 2 km of its length since 1844 (Geovista PDF). The 23-metre Athabasca Falls is not very high by Canadian Rockies standards, but the size of the river makes it one of the most powerful falls to be found in the mountain national parks. Between Whitecourtand Athabasca , the Athabasca River is joined by the Pembina River and Less… We can't have it both ways. There is a good article at Yale 360 on this. Meanwhile, scientific papers had this to say: "During the hot summer of 2003, reduction of an ice field in the Swiss Alps (Schnidejoch) uncovered spectacular archaeological hunting gear, fur, leather and woollen clothing and tools from four distinct windows of time: Neolithic Age (4900 to 4450 cal. [Rob P] - "It is sometimes said" is hardly a sound starting point. A vast river of ice that’s been steadily retreating for 150 years, it and the much smaller Dome Glacier straddle one of the region’s great peaks: Mount Snow Dome (elevation 3,456 m). Perhaps if you listened to experts, who have thought through the issues, you would have different ideas than when you listen to deniers who do not think of the consequences of their actions. IMO, those "bus tours" caring people so spoiled and so thoughtless about their envirinmental destruction, that even mankind AGW fades in comparison.

Note that the dating discrepancy between my account above in the abstract quoted in this paper was due to a redating of the oldest remains after this 2007 paper was published. The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies. And one could argue that once the glaciers are gone, we'll be back to the same point: no net melting of glaciers, just the seasonal snowpack. Consider this: If summer river flows are dependent on glacial meltwater, then those flows would have been lower before the 1800's, assuming there was roughly no net melting of the glaciers then. In North America, the most visited glacier is the Athabasca Glacier, one of six glaciers that spill down the Canadian Rockies from the Columbia Icefield in western Canada. The Icefield Centre is about 64 miles (103 kilometers) from Jasper and 53 miles (185 kilometers) from Banff. Melting glaciers, smaller snowpacks that melt earlier in the year as well as increased demand for water in the N American West, all combine to cause a supply problem. Think through your suggestions so that they make sense. Perhaps I'm wrong about what was supposed to be conveyed? [PS] fixed link - though I am not quite sure of the relevance of a station that is nearly 100km away and 2400m lower. You are positioned at the Toe of the Athabasca glacier. Hence the initial premise of your argument does not hold. Other articles where Athabasca Glacier is discussed: Columbia Icefield: General description: …skyline at the head of Athabasca Glacier, with parts visible as ice cliffs on Snow Dome, Mount Kitchener, and Mount Stutfield. Hidden crevasseshave le… For RCP 2.6 (the low-emissions pathway), glaciers will contribute 125mm (63-181) to sea-level rise (SLR); for RCP 8.5 (the high-emissions pathway), 185mm (95-255). I suppose there is one question worthy of asking - What did happen to the "Green Alp" theory? Moderator `in your reply to Johannesrexx@1 you said:"though I am not quite sure of the relevance of a station that is nearly 100km away and 2400m lower". Athabasca Glacier Facts. I'm really disappointed that those "tours" are still continuing and are not banned yet, which is a symbolic mirror image of the emissions continuing unconstrained. If you want to take a joyride on the glacier, book a tour with the Ice Explorer. The Athabasca Glacier spills down from the Columbia Icefield, an area of ice so massive that you could fit the entire population of North America on it with each person getting at least a square metre of space. NASA monthly data for Banff here. The fact that the station referred to is lower might indicate it has a higher temperature readout than the temperature at the glacier. It's not all about glaciers. Hopefully the moderators will accept one more temperature discussion. (2014), showing the increasing anthropogenic influence on glacier melt. Back to the Athabasca glacier, and the melting of glaciers in the Rockies: I wonder when (or if) the current trends will significantly affect river flows heading west through Alberta. Situated across from the Icefield Centre, its ice is in continuous motion, creeping forward at the rate of several centimeters per day. The global sea level trend through the mid-late Holocene effectively rules out global temperature approaching anything like modern-day. There are two parking lots. • The Athabasca Glacier is one of the most accessible (and thus, busiest) glaciers in North America. In these areas it rains a lot in the winter and spring and little in the summer. and 2790–2590 b.c. 2020 on course to be warmest year on record, Skeptical Science New Research for Week #45, 2020, Solar is now ‘cheapest electricity in history’, confirms IEA, On climate clock, it's parts per million, not minutes, that matter most, 2020 SkS Weekly Climate Change & Global Warming Digest #45, 2020 SkS Weekly Climate Change & Global Warming News Roundup #45, COVID-19 put U.S. back on track with reneged Paris targets, Skeptical Science New Research for Week #44, 2020, CSLDF: Model Language for Scientific Integrity Policies, How you can help to keep Climate misinformation on Twitter in check, Most glaciers are rapidly disappearing all over the world, likely to disappear altogether by mid-century, http://www.wolframalpha.com/input/?i=mount+athabasca+temperature, most of the world's glaciers are diminishing. The Athabasca Glacier One of the six glaciers fed by the vast Columbia Icefield, at six kilometres long and a kilometre wide, Athabasca is renowned as one of the most accessible on the planet. It is just possible to make out some people walking on the glacier on the left-hand side.Click for big. The Columbia Icefield sits astride the continental divide and is 125 square miles full of fields of ice or almost the size of Seattle or Philadelphia! Visitors who return to the glacier a few years after their first visit will notice the change wrought by warming temperatures. The Athabasca Glacier is one of the most accessible “fingers” coming down from the giant Columbia Icefield, the largest icefield in the Rocky Mountains. It is only reasonable to conclude that such widespread phenomena have a common cause, even if you cannot definitively prove causality in particular instances. "Estimating the glacier contribution to sea-level rise for the period 1800–2005." Ashton, if you read the comments (4,5,6,8) you will see that there are other weather stations closer by and others in the region with longer and more complete records than the Jasper station referred to by Jrexx. In Jasper National Park visitors have the rare opportunity to hike on the surface of a glacier, the Athabasca Glacier. 3510–3350 b.c. I visited Athabasca in 1998 and when I saw this 4WD vehicle on huge, mining truck-like wheels full of tourists, whizzing past me, I felt disgusted at its noise and smell of diesel. The Athabasca Glacier in the Canadian Rocky Mountains is probably the easiest glacier in the world to access by car. Visitors who return to the glacier a few years after their first visit will notice the change wrought by warming temperatures. I don't think his argument leads us to the conclusion johannesrexx intends. Perhaps johannesrexx could provide more data to support his claims to show they were not cherry picked. The glacier currently loses depth at a rate of about 5 metres (16 ft) per year and has receded more than 1.5 km (0.93 mi) and lost over half of its volume in the past 125 years.
