For years climate change deniers have brought up the argument of sea ice expansion to challenge the theory that the world is warming. But an international team of researchers found that the mysterious phenomenon may have an explanation: natural variability. Australia and U.S. climate scientists believe that they have evidence that the thickening and expansion of sea ice in the Antarctic are … [Read more...]
Scientists Use Fake Chick to Study Shy Penguins
Emperor penguins are highly sensitive animals. When scientists attempt to personally assess the penguins’ health status, anxiety sets in, disturbing the heart rate and other important indicators. Yvon Le Maho of the University of Strasbourg in France conducted a team which came up with a method to avoid getting too close to the shy animals in Adelie Land, Antarctica. The team constructed a … [Read more...]
Magnetic Pole Reversal Threatens Earth
Although magnetic field shifts are considered to be old news, it may not be so far-fetched to believe that a pilot looking down at the plane controls might suddenly realize that the magnetic North is located somewhere over Antarctica. According to scientists, approximately 800,000 years ago, the magnetic north had indeed hovered over Antarctica and their calculations estimate that a flip could be … [Read more...]
Romanian-American Scientist Discovers Microbial Life in Antarctic Ice Sheet
A diverse ecosystem has been discovered by a team of scientists in an icy lake located underneath the Antarctic ice sheet. The single celled organisms that the researchers have discovered are apparently completely independent from sunlight. Published in the journal “Nature”, the article showed a triumph of engineering and science after the team of scientists dedicated more than 10 years and $10 … [Read more...]
Sea-level likely to Rise at faster as Ice Melts in Antarctica: Australian Study
An Australian research team has found that the sea level is likely to rise at much faster rate than predicted earlier. The researchers hold climate models responsible for the surge in the sea levels as they say the models have failed to account for the disruptive effects of stronger westerly winds. The recently concluded studies on Antarctica ice sheets have suggested the giant glaciers of … [Read more...]
Emperor Penguins More Adaptable To Climate Change to Find New Breeding
A new study released this week led by the University of Minnesota found out that emperor penguins, at least, may be more adaptable than previously expected. It turns out that these penguins are more willing to locate in the face of changing temperatures. Earlier it was thought that the emperor penguin were philopatric that means they return to the same spot, every year to nest and that they are … [Read more...]
Antarctic basin melting faster than estimated
A new study published in Nature indicates that Antarctica's melting glaciers has launched so many icebergs into the ocean, the fastest pulse being the, 1A, 14,600 years ago that it has raised the sea level 6.5 feet (2 meters) in just 100 years. The results are the first direct confirmation for dramatic melting in Antarctica's past. Researchers at UC Irvine and the Jet Propulsion … [Read more...]
Collapsing of Parts of West Antarctica Ice Sheet Has Begun
Antarctica's Thwaites Glacier is losing tens of feet, or several meters, of ice elevation every year. An alarming situation regarding the beginning of the long-freighted collapse of the West Antarctic Ice Sheet has been raised by two scientists. It hit off a centuries-long process that could raise sea levels by as much as 15 feet. "There's been a lot of speculation about the stability of … [Read more...]
Coastal chaos likely as East Antarctica ice sheets Melts, Irreversible Slide
In a glaring exposure, the scientists have found that the vast ice sheets of East Antarctica could begin an irreversible slide into the sea due the rising temperatures and global warming. The melting of ice sheets in East Antarctica may cause an unstoppable process of global coastal destruction, scientists cautioned. It is noteworthy, East Antarctica collectively holds enough water to raise … [Read more...]
Climate change disrupts ocean dynamics in Antarctica
Researchers at McGill University, Canada suggested that heat from the depths of the ocean is being trapped under the Antarctic ice shelf and this could be another effect of climate change. In the 1970s, researchers in Antarctica found an open body of water just like the of New Zealand within, within an ice pack in the Southern Ocean’s Weddell Sea. Eric Galbraith, co-author of the study said, … [Read more...]
