Unexpected Antarctic Glacial Melt Could Cause Sudden Sea Level Rise

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-...

More Melt Than Ever

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...

The Bottom of the Earth is in Trouble Too

Greenland isn't the only place where glaciers are in trouble: While the TOP of the Earth is melting, the BOTTOM of the Earth--the Antarctic--is in trouble too. The polar regions are the most sensitive places...

It's an Invasion

It's like a scene out of a sci-fi movie--thousands, possibly millions, of king crabs are marching through icy, deep-sea waters and up the Antarctic slope. We've had invasions of ants, stinkbugs and (most recently...

Secrets Beneath a Lake

For 15 million years, a frozen lake has been hidden deep beneath Antarctica’s frozen crust, possibly concealing prehistoric or unknown (and perhaps dangerous) life. (NOTE:...

The Bottom of the Earth is Disappearing

?and it's our fault - No matter how cold this winter has been, the truth is: The world is getting warmer. Scientists studying climate change have long believed that while most of the rest of the globe has been getting steadily warmer, a large part of Antarctica?the East Antarctic Ice Sheet?has actually been getting colder. But...

Huge Antarctic Ice Shelf Collapses

Recently pictures of "frozen waves" from the Antarctic have been floating around the internet, pretending to show that it's so cold down under that ocean waves are literally freezing as they break. The reality is that it's summer in the southern hemisphere, and it has been so hot that Adelaide, Australia has experienced a once in 3,000 year...

Mysterious Continent

Antarctica hasn't always been ice free in times of global warming but alas, it's certainly melting now. Parts of the ice sheets covering Antarctica are melting even faster than predicted. NASA scientist James Hansen says that we have to hold our greenhouse gas emissions to 350 parts per million carbon dioxide in the atmosphere. The problem is,...

Antarctica Threatened by Global Warming?And Visitors

The melting ice sheets in Antarctica are a major news item. However, Antarctica is having a lesser-known problem as well: it has become a new tourist destination. The bacteria from the feet of thousands of visitors could cause ecological devastation in the area.

Almost 15,000 tourists a year visit this pristine wilderness area, arriving...

Glacier Collapse Not Due to Global Warming?

The collapse of a giant glacier 10 times the size of Manhattan near Antarctica last week is a natural occurrence and has not been induced by global warming, according to the British Atlantic Survey (BAS). "From the size of it, 41 nautical miles long and four nautical miles wide, it sounds as though it is a normal 'calving' event from the ice...

Another Huge Iceberg Calves in Antarctica

Satellite images from the National Oceanic and Atmospheric Administration (NOAA) have detected another in an increasing series of massive icebergs which have broken off the continent of Antarctica. The new iceberg measures roughly 47 miles by 4.6 miles, or almost ten times the area of Manhattan.

The breakdown of the Antarctic ice sheet,...

Antarctic Penguins Starving to Death

Tens of thousands of penguins are starving to death in Antarctica because a vast iceberg has devastated the regional food chain. The B15 iceberg, which covered about 4,400 square miles when it calved in March 2000, has blocked much of the Ross Sea, preventing the growth of microscopic plants known as phytoplankton that are crucial to the entire...

Ice Shelf Collapse May Cause Antarctica Starvation

As parts of Antarctica are fall into the sea, new satellite data shows that these dramatic changes are affecting the growth of small organisms important to the local food chain. Icebergs that have broken off from the Ross Ice Shelf have caused a 40 percent reduction in the size of the 2000-2001 plankton bloom in one of Antarctica's most...

Sea Levels Rose 200 Feet in Past--It May Happen Again

A massive and unusually abrupt rise in the sea level that occurred about 14,200 years ago was caused by the partial collapse of ice sheets in Antarctica, a new study has shown. In less than 500 years at the end of the last Ice Age, this event caused the Earth's sea level to rise about 70 feet. That?s about four times faster than sea levels were...

Most of Antarctica May Soon Disappear

Tim Naish, of the New Zealand Institute of Geological and Nuclear Sciences, warns that Antarctic?s huge ice shelves may break up completely as the global climate warms. The recent collapse of the Larsen B Ice Shelf in Antarctica was ?a wakeup call to expect more collapses,? he says and believes that such collapses have ?a dramatic effect on...

Huge Piece of Antarctica Floats Away

A piece of the Antarctic ice shelf the size of Delaware has shattered and separated from the continent in the largest such event in 30 years. The Larsen B shelf on the eastern side of the Antarctic Peninsula has fragmented into small icebergs.

Researchers predicted in 1998 that several ice shelves around the peninsula were doomed...

Coastlines After Ice Collapse

Scientists think there is just a one in 20 chance that the West Antarctic Ice Sheet (WAIS) will collapse in the next 200 years. The WAIS is crucial to future sea levels, because if all the ice melts in this region, it could raise ocean levels by several feet.

The West Antarctic Ice Sheet contains about 13% of all the ice in Antarctica,...
