Since 1850 Switzerland's glaciers convey shrunk yesteryear to a greater extent than or less 50%. The World Glacier Monitoring Service say that this procedure is probable to proceed too that fourscore to ninety percent of glacier H2O ice volume volition endure lost yesteryear 2100.
Swiss paper Tages Anzeiger has visualized the extent of Switzerland's shrinking glaciers inwards the terminal 160 years inwards So Schmolzen buy the farm Schweizer Gletscher inwards 160 Jahren Weg. In a serial of multiple mini maps the paper has mapped the alter inwards size of the country's 38 largest glaciers. These maps demo the size of the glaciers inwards 1850 compared to the size of the glaciers inwards 2010. Each mini map includes information on the surface expanse lost inwards kilometers too equally a percent of the glacier's size inwards 1850.
Nearly all of North America's glaciers are too inwards retreat. The charge per unit of measurement of retreat has increased chop-chop over the terminal few decades too overall each decade sees greater rates of retreat than the preceding one. The National Park Traveler has released an interactive floor map, Glaciers inwards Alaska's National Parks: Monitoring Change, which examines the loss of Alaska's shrinking glaciers.
The map uses satellite imagery to demo the modern achieve of each of the featured glaciers. U.S. Geological Survey topographic maps were used to decide the glaciers' extent inwards the mid-20th century. Orange overlays are used on the map to demo this historic extent. This is so compared to the extent of the glaciers inwards the 21st Century, equally calculated from the almost recent satellite imagery.
Alaska Ice: Documenting Glaciers on the Move is some other Esri Story Map which uses satellite imagery too comparisons of modern & vintage photographs to document Alaska's shrinking glaciers.
The top dog focus of the map is the U.S. Geological Survey's Repeat Photography initiative. USGS has been comparing modern photographs of Alaskan glaciers amongst historical photos, both amongst the same champaign of view. The photographs are compared to document too empathise the changes to glaciers resulting from the changing climate.
The Alaska Ice floor map visits fourteen glaciers inwards the U.S. state. Each glacier tin endure viewed on a satellite map too a modern too historical photograph of each glacier is compared inwards the map sidebar. Of the fourteen mapped Alaskan glaciers alone 2 are nevertheless advancing.
Timelapse - aerial imagery of the Mendenhall Glacier inwards 1991 & 2012
Another interesting means to examine the loss of glaciers is amongst Google Timelapse. Timelapse allows y'all to compare aerial imagery over fourth dimension for whatsoever place on Earth. You tin thence larn into the cite of whatsoever glacier into Timelapse too divulge the effects of global warming for yourself.
Timelapse provides links to the Shirase Glacier too the Columbia Glacier simply y'all tin role the search box to locate whatsoever glacier. You tin thence role Timelapse to search for whatsoever of North America's or Switzerland's glaciers too divulge the highlighted loss of each glacier for yourself, using Timelapse's historical aerial imagery.
