Scientists have coaxed back to life moss that had been frozen on an Antarctic island for more than 15 centuries.
Researchers at NYU found that in the current warm phase of the tropical Atlantic oscillation, a change in wind patterns pushes warm air aong the Antarctic Peninsula.
Breakup of the shelves can accelerate the flow of continental ice to the sea, contributing to sea-level rise, and the Antarctic shelves 'are melting too fast,' the study's lead author says.
Two different areas of Antarctica tell two very different stories about how climate change might be affecting ice melt. The data appear to confirm that climate change impacts can be very local.
Average temperatures in West Antarctica rise 4.3 degrees since 1950s. The region's warming is nearly twice as much as expected and one of the most rapid on the planet.
Centuries before fossil fuel emissions began warming the globe, Antarctica was heating up, indicates a new research published in Nature.
Rapid warming of the Antarctic Peninsula is bringing temperatures close to the warmth that followed the end of the last ice age, says lead researcher Richard Mulvaney, a paleoclimatologist with the British Antarctic Survey.
A humongous rift located under West Antarctica that provides a channel for warm ocean water to creep toward the interior of the ice sheet could be accelerating ice loss, say scientists.
Researchers at the Woods Hole Oceanographic Institution have found that melting sea ice could lead to dramatic declines in populations of emperor penguins.
A population of chinstrap penguins in Antarctica has seen a 36 percent decline since 1991, in what researchers say is a consequence of declining krill populations.
