Global Glacier Retreat

[mlawren7]

This is great sci-fi, but in fact the world's glaciers have not been doing that.

[JessFromMead]

Since 1900 to today Of course the glaciers would have moved back. If the temperature of the world goes down just by a few degrees, We could enter an Ice Age. and the worlds been in a constant warm cold cycle according to Geologists. Dont questions Earths histroy, it will kick you in the ass

Why won't you report that only one side of antarctica is breaking, the other side and most of the continent and associated glaciers are actually getting colder and the ice thickening? Why won't you report that mankind only contributes 3% of greenhouse gasses? Why won't you report that carbon dioxide is no more of a pollutant than oxygen? Why do you keep saying global warming when true science shows the world is cooling down? Why won't you report that ...

damn you global warming!!!!

This is gross and insipid.

[AnonymousWhitePerson]

During the Triassic period the CO2 level was 6 times that of today. During the Carboniferious, 3 times that.

[WaxItYourself]

@AnonymousWhitePerson Well gee. I guess the world would be a mighty fine place then if atmospheric CO2 concentration was 2400ppm. Of course we'd have to look past the fact that the top level of CO2 that is safe for humans is 1000ppm and some people feel light headed in a 600ppm atmosphere. But of course your awesome knowledge of science outdoes realty doesn't it?

[AnonymousWhitePerson]

To make it appear that these Glaciers Melted, they simply Zoomed out, making it appear to have receded in 80 years.

A perfect example of this deception is at 0:34 to 0:36.

[tastybrain]

@AnonymousWhitePerson You are a retard. Anyone can see that there is no zooming by looking at the rocks in the landscape which is framed exactly the same.

[MrBigwong]

Are any of these near Yosemite?

[brianwlevine]

awesome. i'm using this for a class on climate change, thank you!

[liOVERLOADil]

You get an F.

[utoobsta]

Excellent video, but were the photos taken at the exact time of year as the old photos?

[xeniacolours]

Some are some are not. As the mass of glaciers does not change much due to seasonal effects the exact time of recording would be interesting but of no importance to the trend shown.

Oh it is so sad!

[laguschiu]

A video that makes it really clear the raising of temperature. A video really exceptional!!! Thanks from Luciano!!!

Wonderful video!! Thank you so much for putting this on youtube.

An estimated 1.5 to 2 billion people in Asia (Himalayan region) and in Europe (The Alps) and the Americas (Andes and Rocky Mountains) depend on river systems with glaciers inside their catchment areas. In areas where the glaciers are melting, river runoff will increase for a period before a sharp decline in runoff. Without the water from mountain glaciers, serious problems are inevitable.
