Recent work has suggested that sections of the West Antarctic ice sheet are already rapidly retreating, raising concerns about increased sea-level rise; now, an ice-sheet model is used to simulate the mass loss from the entire Antarctic ice sheet to 2200, suggesting that it could contribute up to 30 cm of sea-level rise by 2100 and 72 cm by 2200, but is unlikely to contribute more.
Retreating glaciers over the last 14,000 years caused a population explosion among Adelie penguins – a trend that could continue as Antarctic ice shrinks further thanks to global warming.
Major, long-term environmental changes are projected in the Southern Ocean and these are likely to have impacts for marine predators such as the Adélie penguin (Pygoscelis adeliae). Decadal monitoring studies have provided insight into the short-term environmental sensitivities of Adélie penguin populations, particularly to sea ice changes. However, given the long-term nature of projected climate change, it is also prudent to consider the responses of populations to environmental change over longer time scales.
NEW DELHI: A startling new report by Nasa scientists suggests that the Antarctic ice sheet may actually be expanding, growing every year, despite a warming globe!
MIAMI: Melting ice in West Antarctica is a major concern for global sea levels, and a key area may already be unstable enough to unleash three meters of ocean rise, scientists said Monday.
The U.N.'s weather and climate agency said on Thursday there was no cause for alarm about a record-size hole this month in the ozone layer, that shields life on earth from the sun, as it should shr
A jump in global average temperatures of 1.5 degrees Celsius to 2 degrees Celsius will see the collapse of Antarctic ice shelves and lead to hundreds and even thousands of years of sea-level rise,
