Medicine & TechnologyA part of Antarctica that scientists once thought to be safe from climate change is now showing signs of instability, and the loss of this ice could lead to the rising sea levels around the world.
Antarctica is a truly massive continent. At over 5 million square miles, the whole of the US could fit securely within its borders. It boasts the highest, driest, coldest, and windiest landscape of all seven continents. And the fact that it is losing ice is nothing new. It's the rate at which parts of the continent are melting that is raising new concerns.
The last intact section of one of Antarctica’s giant ice shelves is weakening fast and will likely disintegrate in the next few years, contributing to a further rise in sea levels, NASA said in a new study.
Though it may be hard to imagine life abounding in the frigid tundra that is Earth’s Antarctica, that doesn’t mean that life cannot exist there. Recent studies looking into the develop and sustainability of life in the frozen wasteland has developed promising results in showing that life may too exist on other exoplanets or exomoons further out in space that may share a similarly cold surface. But in a new study published this week in the journal Nature Communications, researchers with the University of Tennessee Knoxville have discovered a series of underground lakes that could harbor life—pointing ever-more towards the possibility of life far off from what humans can withstand.
Times are tough for the massive ice sheets of Antarctica these days with the latest report that the giant floating ice shelves that form a fringe along the continent's coast are beginning to melt and deteriorate much faster than scientists once believed.
Surviving an Ice Age may sound like an easy task for a penguin. However, a new study of how climate change has affected emperor penguins over the last 30,000 years found that only three different populations of penguins survived during the last ice age, and the Ross Sea in Antarctica was likely the refuge for one of the populations.
What could be worse than living on a frozen tundra, you ask? Experiencing the world in only two tastes has got to be pretty rough. And when you’re noshing down on fish day in and day out, only being able to taste things that are salty or sour has got to be a bummer too. But sadly, this is the life of the penguin.
In a surprising twist, scientists drilling through 2,500 feet or 740 meters of ice in Antarctica have stumbled upon a colony of fish, crustaceans and jellyfish inhabiting the cold and dark recesses of the barren Antarctic sea floor.
While past research has described the specie in great detail, a new study has found that Antarctic seals may be using the Earth's magnetic field as a natural GPS while hunting.
As impending threats of “climate change” and “ecological disaster” have loomed over international affairs this year, to the point that even the United Nations spearheaded a campaign and led a summit to discuss future changes that may amend for some of humanity’s grave mistakes, new research published this week in the journal Geophysical Research Letters looks to a place much colder than our metropolises for evidence of a rapidly shifting climate.
Looking for a way to observe king penguin colonies in the ice fields of Antarctica, researchers led by Yvon Le Maho from the University of Strasbourg, France developed a fluffy little rover shaped in the image of a penguin chick so that they could get an up-close view of the male penguins’ nesting behaviors.
In Antarctica, much of life and history is swept away or covered completely by ice and snow. Even in the face of unending change, the surface appears timeless and constant, even though it sets the stage for some of the most tragic stories south of the equator.
The Antarctic ice is host to very little life, yet often researchers find that beneath the frozen surface we find remnants and a record of our past. Core ice samples not only reveal atmospheric concentrations of particular molecules in ancient skies, giving us a view of how the Earth’s climate has changed over eons even before the arrival of man, but also sometimes reveals a view of our own history on the icy sheet. This week, after more than a century since it was written and lost in a tragic expedition, the preserved journal of explorer George Murray Levick was found by researchers who recovered the photographic treasure from a casing made entirely of ice.
