Technically referred to as sedaDNA – for sedimentary ancient DNA – the recovered samples are likely to prove useful in the ongoing efforts to understand how climate change could affect Antarctica in the future.
Eastern Antarctica has recorded exceptionally high temperatures in March, more than 30 degrees Celsius above normal, say experts.
A swarm of crab-like creatures were found 1,600 feet under the Antarctic ice in a freshwater river, signifying an unexplored ecosystem.
Totality was visible only in Antarctica on early Saturday, experienced by a small number of scientists experts and adventure tourists.
With this, Antarctica has now become one of the fastest-warming regions in the world - registering a rise of almost three degrees Celsius in the last 50 years.
The massive chunk of ice floating in the Weddell Sea was first spotted on May 13 2021, measuring approximately 170 km long and 25 km wide, it boasts a surface area of 4,300 sq km and is currently the world's largest iceberg.
A giant iceberg, larger than the size of most European cities, has broken away from Antarctica. Scientists had been expecting a huge chunk of ice to break away for almost a decade after the first "vast cracks" had formed.
The Ozone hole over the Antarctica continent has become unprecedentedly deeper and larger in the last 15 years, the latest finding of the World Meteorological Organization has shown. It has reached its peak of at 24 mil square km.
Scientists believe that immense quantities of methane are stored under Antarctica’s seafloor. They don’t know the leak’s cause, but global warming probably isn’t to blame, since the Ross Sea has not yet warmed significantly.
Temperature data shows that the desolate region has warmed at three times the global warming rate over the last three decades up through 2018, the South Pole's hottest year on record.
A recent study found that, in the last three decades, the region has warmed at three times the global rate, with an increase of 0.61°C per decade.
A team of scientists drilled into the ground near the South Pole to discover that 90 million years ago Antarctica was once home to a swampy rainforest and had average temperatures around +11C.
In nearly three decades, Denman Glacier has already retreated some five km and lost over 250 billion tons of ice. In the worst case scenario, the damage could be much greater.
The island—named Sif after the goddess of Earth and the wife of thunder god Thor—is big enough for satellites to spot from space but had previously been hidden under ice. Climate change is likely to blame for the reveal.
On February 6, 2020, weather stations recorded the hottest temperature on record for Antarctica. Thermometers reached 18.3 C (64.9 F). During the warming event, around 1.5 square km of snowpack became saturated with melt water.
