Glacier National Park might presently need a new name .
The Montana park has 26 mention glaciers today , down from 150 in 1850 . Those that rest are typically mere remainder of their former frozen ego , a new gallery of before and after images reveals .
Glaciers Disappear in Before & After Photos
All argumentation about global thawing aside , now is a clip of clear retirement by age - old Methedrine packs in many locations around the world . Some retreat just a few inch or feet per year , but others aremeltingfaster than a nose candy cone in Texas .
80 feet per day
Montana might not be the first place that comes to mind when you recall of glacier . Elsewhere , however , the situation is similar .
The Columbia Glacier in Prince William Sound , the world ’s fastest - dissolve glacier , slides into the ocean at a rate of 80 invertebrate foot per Clarence Day . This tidewater glacier is up to 3,000 feet duncical , but it has thinned up to 1,300 infantry in place during the past 25 years , and researchers say it ’s stretching like taffy . Each class , it dump 2 cubic miles of ice into the sound .
InGreenlandit ’s not rare now for glacier to recedeseveral milesin one yr .
Fast or tedious , the melting is unremarkably a gradual process compared to , say , a glut , rushing river . But sometimes glaciers can dampen to the point where they of a sudden , and noisily , collapse . One dramatic example of a ready break is theLarsen B ice shelfinAntarctica(this collapse also unwrap a surprisingly thrivingunderwater earth ) .
Along with glacial thawing , permafrost around the globe isturning to mush , cause basis to plainly collapse .
All this melting might extend one to think thatland is being freed up , but a raw study suggests just the contrary . Melting glaciers , a resultant role ofglobal thaw , could causesea levelsto rise as much asthree metrical foot per 100 , submerging coastal realm .
summer in parts of the Arctic could beice freein the next 100 days , which could prove daunting for the existence of polar bears .
Closer to home
chicken feed in Glacier National Park is also disappearing .
In 1997 the U.S. Geological Survey set about the Repeat Photography Project in the Montana park to compare how glaciers have changed over the last century . lensman returned to fix where old - timekeeper had remove photos long before they could peradventure have think their scientific time value . Locating these advantage point was the slick part of the project , as some required panoptic off - lead tramp .
The before and after pictures [ Gallery ] released this hebdomad are dramatic — all that remains of some glaciers are braggart puddle . Others have simply faded out to expose bare mountainside . The images were conduct at similar times of year under similar conditions .
Based on the pictures and global recession rates , scientist prefigure that the parking lot will be glacier free by 2030 .
Whileglobal warminggets most of the blame for glacier niche , soot pollutionfrom automobiles and industrial chimney might also play a function . clear , shiny chicken feed reflects sunlight and remains cool . But dirty , soot - covered ice absorbs more warmth from the sunshine , causing a glacier to meld more rapidly .

Glacier fact
About 10 percentage of Earth ’s country is covered with glacier .
During the last Ice Age , glacier covered 32 percent of land .
Glaciers store about 75 percent of the world ’s fresh pee .
Antarctic water ice is more than 2.6 miles ( 4,200 time ) thick in some areas .
If all body politic ice melted , sea level would rise approximately 230 human foot ( 70 meters ) worldwide .
