A lengthening crack is threatening to cause an Antarctic ice shelf to collapse

A lengthening crack is threatening to cause an Antarctic ice shelf to collapse About 10 to 12 percent of the Larsen C Ice Shelf is expected to break off during such an event, leaving the larger ice shelf even more vulnerable to melting from increasing air and ocean temperatures.The iceberg and ice shelf melting would not, however, increase sea levels, since the ice is already resting in the ocean, like an ice cube in a glass.

NASA, SpaceX, and Virgin Galactic dominate the news: this week in space

NASA, SpaceX, and Virgin Galactic dominate the news: this week in space His legacy as a combat pilot, spaceman, senator, and loving family man will succeed him, along with the John Glenn Research Center in Cleveland.Godspeed, John Glenn.

The Terra Nova expedition: An ambitious and ill-fated attempt to reach the South Pole

The Terra Nova expedition: An ambitious and ill-fated attempt to reach the South Pole In 1910, British explorer Robert Falcon Scott embarked on an ambitious expedition to Antarctica, aiming to explore uncharted wastelands, conduct scientific studies and above all else, become the first person to reach the South Pole.Ernest Shackleton had come within 100 miles of the pole the previous year, and Norwegian explorer Roald Amundsen also had his sights set on reaching it first.

Startling aerial video reveals massive crack in Antarctic Ice Shelf

Startling aerial video reveals massive crack in Antarctic Ice Shelf The crack is expected to give rise to one of the largest icebergs on record, sometime within the next few months, though the precise timing of the breakup is unclear.Researchers from Project MIDAS, led by Swansea University, have reported several rapid elongations of the crack in recent years.

Here's what the Ice Age tells us about future sea level rise

Here's what the Ice Age tells us about future sea level rise Glaciers in Greenland, Antarctica and other areas have been melting rapidly in recent years due in part to increasing ocean temperatures.They also used Bassis' mathematical model for describing how ice reacts to air and ocean temperatures, and the implications for sea level rise.

'Ring of fire' solar eclipse will blaze across the Southern Hemisphere

'Ring of fire' solar eclipse will blaze across the Southern Hemisphere A "ring of fire" eclipse will be visible from the Southern Hemisphere on Sunday morning, although anyone can catch the spectacle live via the space site Slooh.It happens when the moon slides in between the sun and the Earth but doesn't completely block the sun, as would a total solar eclipse.

Antarctica has way more penguins than scientists thought, which is great, because penguins

Antarctica has way more penguins than scientists thought, which is great, because penguins Millions more Adélie penguins may be marching across Antarctica than earlier counts suggested.Nearly six million of the tuxedoed penguins may live in East Antarctica, more than double the previous count of 2.

Earth just had its second-warmest February since 1880

Earth just had its second-warmest February since 1880 Last month was Earth's second-hottest February on record since at least 1880, NASA and the National Oceanic and Atmospheric Administration (NOAA) recently reported.In February 2017, the average global temperature was 1.

NASA photos capture a strange new crack in a massive Greenland glacier and we're all probably doomed

NASA photos capture a strange new crack in a massive Greenland glacier and we're all probably doomed A mysterious crack has been spreading across a giant Greenland glacier, and it's raising concerns that part of the floating ice shelf could splinter off into the ocean.The new chasm appears in the center of the glacier's floating ice shelf — the tongue of ice that extends into the water from the grounded glacier on land.

Stunning underwater footage shows serene whale's-eye view of Antarctica

Stunning underwater footage shows serene whale's-eye view of Antarctica Scientists are diving deep off the coast of Antarctica to help protect whale feeding areas.But they're not jumping into the frigid Southern Ocean themselves.

Even penguins marched (well, waddled) for science

Even penguins marched (well, waddled) for science What's better than clever protest signs?On Saturday, as thousands of people joined the March for Science worldwide, a group of penguins waddled in solidarity at the Monterey Bay Aquarium in California.

Big tires and jet fuel helped this Hyundai Santa Fe cross Antarctica

Big tires and jet fuel helped this Hyundai Santa Fe cross Antarctica It may be named for a city in the sunny American Southwest, but the Hyundai Santa Fe has proven its mettle in some colder conditions.A modified Santa Fe crossed Antarctica, making it the first passenger car to do so, according to Hyundai.

The sea would swallow these cities under an 'extreme' scenario

The sea would swallow these cities under an 'extreme' scenario Until recently, it seemed that we would be able to manage global warming-induced sea level rise through the end of the century.Recently, the National Oceanic and Atmospheric Administration (NOAA) published an extreme high-end sea level rise scenario, showing 10 to 12 feet of sea level rise by 2100 around the U.

Antarctica's Blood Falls mystery has been solved

Antarctica's Blood Falls mystery has been solved We may finally have an explanation for a red waterfall in Antarctica that has puzzled visitors and researchers since its discovery in 1911.Blood Falls may owe its rusty, bloody color to salty water that has been trapped under the Taylor glacier for more than 1 million years.

A rift that's about to cleave off a massive iceberg has a sibling, and that's no good

A rift that's about to cleave off a massive iceberg has a sibling, and that's no good Using a highly-sensitive European Space Agency satellite known as Sentinel-1, scientists have been tracking the progress of a lengthening and widening crack across the floating Larsen C Ice Shelf.However, while progress of the main rift seems to have slowed, scientists have spotted a "new branch" of the rift heading toward the ice front, where the ice shelf meets the sea.
