Earth's Melting Glaciers Captured in Stunning Before-and-After Images

Popular

If you don't agree with 97 percent of climate scientists that climate change is real, you should at least believe your own eyes.


The Earth's rapidly rising temperatures has dramatically transformed our landscapes, as you can see quite clearly in these vivid photos of the world's melting glaciers.

The photos appeared in the new paper "Savor the Cryosphere," published in the peer-reviewed GSA Today, a publication of the Geological Society of America. The cryosphere is the Earth's frozen waters.

"We have unretouched photographic evidence of glaciers melting all around the globe," co-author Gregory Baker, adjunct professor of geology at the University of Kansas, said.

"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."

Baker's research career centers on geophysical imaging of Earth's subsurface and geoscience education.

Photographer James Balog, who was featured in the Emmy Award winning climate change documentary, Chasing Ice, contributed photographs from the Extreme-Ice Survey.

Other co-authors of the paper include Richard Alley, an American geologist who was invited to testify about climate change by Vice President Al Gore; Patrick Burkhart of Slippery Rock University; Lonnie Thompson of the Byrd Polar Research Center at Ohio State University; and Paul Baldauf of Nova Southeastern University also contributed to the paper.

The team hopes the paper will raise awareness about the world's melting glaciers.

"We have all heard of the impact of melting ice on sea level rise, but the public also need to be aware that places around the world depend on glaciers for their water and are going to come under increasing stress, and we already see how water shortages lead to all kinds of conflict," Baker said.

"The other critical point often overlooked is that when glaciers melt we're losing these scientific archive records of past climate change at specific locations around the Earth, as if someone came in and threw away all your family photos."

"Glacier ice contains fingerprint evidence of past climate and past biology, trapped within the ice," Baker continued.

“Analyzing ice cores is one of the best ways to analyze carbon dioxide in the past, and they contain pollen we can look at to see what kind of plant systems may have been around. All of this information has been captured in glaciers over hundreds of thousands of years, and sometimes longer—Greenland and Antarctica cover perhaps up to a million years. The more that glacial ice melts, the more we're erasing these historical archives that we may not have measured yet in some remote glaciers, or deep in ice caps, that can tell us the history of the Earth that will be gone forever."

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

Kokia drynarioides is a small but significant flowering tree endemic to Hawaii's dry forests. Native Hawaiians used its large, scarlet flowers to make lei. Its sap was used as dye for ropes and nets. Its bark was used medicinally to treat thrush.

States that invest heavily in renewable energy will generate billions of dollars in health benefits in the next decade instead of spending billions to take care of people getting sick from air pollution caused by burning fossil fuels, according to a new study from MIT and reported on by The Verge.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.

It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
