Photographic Proof of Climate Change: Time-Lapse Images of Retreating Glaciers
1 of 13
A team of scientists has put together photographic "proof" of climate change, revealing time-lapse photo couplets, or before/after images, of retreating glaciers. Their research and photos are published online March 30, 2017 in the journal GSA Today.
"We have unretouched photographic evidence of glaciers melting all around the globe," study co-author Gregory Baker, a geologist at the University of Kansas, said in a statement. "That includes the ice sheets of Greenland and Antarctica — they're reduced in size. These aren't fancy computer models or satellite images where you'd have to make all kinds of corrections for the atmosphere. These are simply photos, some taken up to 100 years ago, and my co-authors went back and reacquired photos at many of these locations. So it's just straightforward proof of large-scale ice loss around the globe."
Take a look for yourself.

Columbia Glacier - BeforeThe Columbia Glacier, which is located on the southeastern coast of Alaska, is called a tidewater glacier, meaning it flows directly into the sea, according to NASA's Earth Observatory. In 1794, British explorers surveyed the glacier, showing its nose (called the terminus) jutted out to the northern edge of Heather Island, near the mouth of Columbia Bay, the Earth Observatory reported. "The glacier held that position until 1980, when it began a rapid retreat that continues today," said the Earth Observatory. This image shows the glacier in 2009.
