Global Warming

wendeldouglas3 — 2014-12-17 18:33:31 UTC

+ Every single day, 70 million tons of carbon dioxide are released into our world's atmosphere.

+ 2008 saw the second-lowest summer Artic sea ice ever recorded since satellites began keeping

track in 1979, at 1.74 million square miles.

+ The warmest years on record have been in the past 10 out of 12 years.

+ Ships for the first time can sail along the Northwest Passage above North America.

+ Artic summers could be ice-free by 2040.

+ 82% of glaciers have disappeared in Glacier National Park, Montana.

+ 500,000 cubic miles of ice would be lost if either of the rapidly melting ice sheets in Greenland

or Antarctica completely melted.

+ 20 Million tons of ice per day are lost by only one of the glaciers in Greenland

+ Over a hundred million people will be displaced by just a 1-yard rise in sea levels

+ Sea levels will rise by 20 feet if either the Greenland of West Antarctica Ice Sheets completely melt - 40 feet if both melt.

North West Passage

The North West Passage is now passable due to melting glaciers.
