News Stories relating to "glacier"

Scientists have been concerned for many years that the collapse of a continental glacier on Greenland or the Antarctic could result in a rapid and dangerous rise in sea levels, and now the surprising condition of an Antarctic glacier has seriously increased that concern.
A group of international scientists recently led a two month-...

Climatologists have discovered that West Antarctica is warming TWICE as fast as they previously thought it was.
This unexpectedly big increase adds to fears the ice sheet will thaw, causing the sea level to rise and drown coastal cities all over the world. West Antarctica holds enough ice to raise world sea levels by 11 feet if it...

We didn't really know--until now. The ocean, which has risen an average of 8 inches since 1900, should rise another 3 feet or so by 2100, but without an accurate record of where we started, we can't know if the melting starts to speed up or (hopefully) slow down.
On the Climate Central website, Michael D. Lemonick quotes researcher...

One of the world's leading ice experts has predicted the final collapse of Arctic sea ice in summer months within four years. That's earlier than the Earth's predicted demise in December of 2012
, but it could be a major cause of it.
In the September 17th...

NASA doesn't just search for life on other planets
, its satellites also search the Earth for evidence of melting glaciers. Their "IceSat," which uses lasers to measure the thickness of ice, has discovered that Arctic ice is vanishing 50% faster than expected--at a...

When it comes to climate change
, the answer is probably "no." Unknowncountry.com's Climate Watch
warned that extreme summer ice melt this year will be accompanied by methane outgassing that will, in...

The Arctic is melting
, but not everyone is worried--in fact, it's opening up large reserves of oil and minerals that are causing a "cold rush" by various countries who want to mine the area. It may even lead to a new "cold war:" The US recently...

A study of hailstones has found large numbers of bacteria at their cores. It turns out that the bacteria help create the snow and hail, since their coating of protein causes water to freeze at relatively warm temperatures. In fact, bacteria works so well that it's used in snow-making machines.

The 6.3 magnitude earthquake that struck Christchurch, New Zealand on Feb. 22 demonstrates the vulnerability of urban centers with important lessons for the US. And a 30 million ton block of ice sheared off a New Zealand glacier just minutes after the violent earthquake there. Civil engineer Thomas D. O'Rourke says, "Some reasons for the...

While most glaciers are melting
at an alarming rate, one of them is growing bigger--ALSO as a result of climate change
. Hotter summers may actually slow down the melting rate of glaciers. Researchers have learned that...

Greenland's ice sheet, which could be a major cause of rising sea levels, melted at a record rate
in 2010. And a look at an ice field atop the highest mountain in the eastern European Alps suggests that the glacier may hold records of ancient climate extending back as much as a...

And gives birth to a BIG one! - An "ice island" four times the size of Manhattan has calved from a glacier in Greenland. The last time the Arctic lost such a large chunk of ice was in 1962.
The Petermann Glacier, the parent of the new ice island, is one of the two largest remaining glaciers in Greenland that terminate in...

Glaciers are melting at an alarming rate, threatening to raise sea levels and drown coastal cities. Now a German geologist has developed a method to slow down, or even stop, the melt.
Researcher Hans-Joachim Fuchs wants to install fans on melting glaciers that will blow cold air from the glacier onto the dissolving ice, slowing down (or...

The rate at which glaciers are melting all over the world has more than doubled, and some of the biggest melts are occurring in mountain ranges in Europe, not in the Arctic or Antarctica, where you would expect most of it to be happening.
BBC News quotes UN Under Secretary Achim Steiner as saying, "There are many canaries emerging in the...

Word has just leaked out that the ice sheet that covers Greenland is melting. This means we could face a rise in sea levels that will flood huge areas in the world?s most populated regions, according to a report by the United Nations Intergovernmental Panel on Climate Change (IPCC). Dozens of countries may be wiped off the map.
