Scientists explain melting of Antarctic ice sheet dating back 9,000 years
Scientists have found evidence that between 9,000 and 5,000 years ago, in a period termed mid-Holocene, the East Antarctic ice sheet in Queen Maud Land melted rapidly during the time when the world experienced warmer-than-present summers. They said that this ice sheet sector in East Antarctica was thinner following the end of the last ice age, when massive ice sheets previously covered North America, northern Europe and southern South America. When these ice sheets melted, they raised the sea level by more than 100 metres. For context, if absolutely all of Antarctica's present day ice melted, the seas would rise by 58 metres on average. Sixty per cent of the world's fresh water is bound up in Antarctic ice sheets. "The ice sheet in East Antarctica stores enormous amounts of water. This means that this is the biggest possible source of future sea level rise - up to 53 metres if all of the East Antarctic ice melts - and is seen as the largest source of uncertainties in the future sea

Scientists find microplastics in fresh Antarctic snow for first time
Scientists have found microplastics in freshly fallen Antarctic snow for the first time, which they said has the potential to influence the climate by accelerating melting of ice

Warmer summers threaten Antarctica's giant ice shelves: Study
The study found that total lake volume varies between years by as much as 200% on some ice shelves and by up to 72% across the entire ice sheet, with large differences between ice shelves
