Glaciers May Vanish in 'Geologic Instant'

Prehistoric glacier's rapid meltdown could happen again: researchers

(Newser) - New data about a prehistoric Canadian glacier that rapidly vanished is giving scientists a stronger model to predict the radical effects of climate change. It's very possible that the same conditions could quickly shrink today's larger ice sheets in Greenland and Antarctica, prompting sea levels to soar in a "...

Argentine Glacier Grows Despite Global Warming

(Newser) - Argentina's Perito Moreno glacier is one of only a few ice fields worldwide that have withstood rising global temperatures. Nourished by Andean snowmelt, the glacier constantly grows even as it spawns icebergs the size of apartment buildings into a frigid lake, maintaining a nearly perfect equilibrium since measurements began more...

Radar Reveals Antarctica's Hidden 'Alps'

Mapping expedition uncovers 'Alps' that show how ice sheet was formed

(Newser) - Scientists using radar to map what lies beneath two miles of Antarctic ice have discovered a landscape similar to Europe's Alpine region, the BBC reports. The sharp peaks and deep valleys surprised researchers who expected the area to have been ground much flatter by shifting ice. Researchers believe the findings...

Study Predicts Rising Seas in Northeast

(Newser) - Increases in sea level caused by climate change could be dramatically larger than the world average in the densely populated Northeast, LiveScience reports. A new study shows that the melting Greenland ice cap and ocean dynamics will push 12 to 20 more inches of water toward New England and Canada...

In Alaska, Melting Glaciers Cause Land to Rise

Glaciers receding 30 feet each year

(Newser) - Around Juneau, Alaska, climate change is causing an unexpected problem, the New York Times reports: As glaciers melt, the land is rising away from the sea. The change—10 feet in about 200 years—is enough to dry up local streams and wetland habitats, and is the result of land...

World's Rivers Running Low: Study

(Newser) - The world’s rivers are drying up as climate change worsens and the demand for water increases, the BBC reports. Researchers studying 925 major waterways—from the Ganges to the Colorado—found significantly less fresh water flowing into oceans in 2004 than 50 years earlier. If the trend continues, the...

Swiss-Italian Border Moves as Glaciers Melt

Alpine borderlines changing along with the climate

(Newser) - The rapid melting of Alpine glaciers has prompted Swiss and Italian authorities to redraw the border between the two nations, the Independent reports. Authorities believe the border will need to be moved by hundreds of feet in some places as glaciers have shifted and permafrost has disappeared, changing the course...

Global Warming Will Buoy East Coast Sea Level

Altered Atlantic current means higher flood risk from Boston-DC

(Newser) - The effect of climate change on Atlantic currents will boost the threat of flooding along the US East Coast more than glacial melting alone, a study predicts. New York, Boston, and Washington, DC, are expected to experience more shoreline encroachment and have higher risk of storm surges as changing currents...

Alps Artifacts Offer Clues to Climate Change

Ancient objects emerge as Swiss glacier melts

(Newser) - A melting glacier in the Swiss Alps has revealed hundreds of ancient artifacts, providing valuable information about both history and climate change through the ages, AFP reports. The area was walkable only during warm periods when the glacier receded. “The site itself is the most important find because we...

Scientists Spot Crack at Top of the World

Northern Hemisphere's largest floating glacier breaking up

(Newser) - A huge crack—seven miles long and a half-mile wide—has opened in a northern Greenland glacier as an 11-square-mile chunk of ice appears to be breaking off. The phenomenon is occurring in the Northern Hemisphere's largest floating glacier, once thought largely immune to the effects of global warming, reports...

Initial swelling causes 'river tsunami'; global warming blamed

(Newser) - Melting ice in a remote Chilean lake caused it to swell and suddenly empty, creating a “river tsunami,” the AP reports. Water from a melting glacier filled the lake and tunneled through the ice, emptying into a nearby river.

Glacial Melt Hit Record in '06

Study finds glaciers lost an average of 4.9 feet of ice

(Newser) - Glaciers shrank an alarming average of 4.9 feet in 2006, the UN Environment Program says—a dramatic difference from ice loss numbers in the ‘80s and ‘90s, when glaciers lost an average 11.8 inches a year. UNEP’s director pointed to "many canaries in the...

Ancient Antarctic Volcano May Be Linked to Warming

Scientists make 'unique' discovery beneath continent's massive ice sheets

(Newser) - The discovery of what scientists are hailing as the first evidence of a volcanic eruption under Antarctica’s massive ice sheet may be linked to climate change, the BBC reports. British researchers, who discovered evidence of a volcano by analyzing radar data from an air survey, believe the eruption likely...

Earth at 'tipping point' of irreversible catastrophe: UN chief Ban Ki-Moon

(Newser) - The last and most forceful of a series of UN reports on climate change unveiled today urges swift action to avoid "abrupt and irreversible" damage to the environment. Melting glaciers will cause a rapid rise in sea levels, wiping out vulnerable species and destroying water and food supplies for...

Melting Alaska, Tourist Hot Spot

Visitors flock to see climate change first-hand

(Newser) - Tourists traditionally head to Alaska for cruises and fishing, but for a growing number, it’s a global warming pilgrimage. Heating up five times faster than anyplace else, Alaska has drawn politicians, scientists, and now tourists to see the melting future, the Christian Science Monitor reports. “This has immediate...

5 Last-Ditch Plans to Save Earth

Crank up your ingenuity and combat climate change the MacGyver way

(Newser) - If reducing emissions was Plan A to save the earth from global warming, these plans from Popular Science would be more like Plan ... Z:
  1. Make more Arctic ice—out of saltwater.
  2. Cool the oceans, which feed storms with warm water, by sucking up cold water from the ocean floor with

Global Warming Protesters B-r-r All on Glacier

(Newser) - Hundreds of naked people bared all on a Swiss glacier to protest global warming yesterday. The arresting demonstration was photographed by New York artist Spencer Tunick, known for his photos of nude gatherings, as temperatures hovered around 50 degrees.

Frozen DNA Survives After 8 Million Years

Microorganisms from Antarctica look like Martian data

(Newser) - Scientists have nixed the notion that glaciers are lifeless blocks of ice by thawing chunks containing Antarctic organisms and watching them successfully divide on their own, the Los Angeles Times reports. The study suggests that these microorganisms, ranging from 100,000 to 8 million years old, could yield DNA and...

Asian Brown Cloud is melting Himalayan glaciers

(Newser) - An enormous cloud of smog over southern Asia threatens 2 billion people with flooding and drought, a new study shows. The "Asian Brown Cloud" is melting Himalayan glaciers, the Times of London reports, and the resulting floods will menace heavily populated downstream areas. And the cloud's driving up temperatures...

A crack in the ice wall's to blame, scientists say

(Newser) - A Chilean lake that mysteriously went missing between March and May was a casualty of global warming, says the lead scientist investigating its disappearance. Melting glaciers created a stream of water that cracked one of the lake's ice walls, sending the water pouring into an adjoining fjord and, eventually, out...
