Some Antarctic ice shelves have GROWN in the last 20 years despite global warming - Daily Mail

During the late 20th century, high levels of warming in the eastern Antarctic Peninsula led to the collapse of the Larsen A and B ice shelves in 1995 and 2002, respectively. .

There was then a period when some ice shelves in the eastern Antarctic grew in area, despite global warming. .

During the late 20th century, high levels of warming in the eastern Antarctic Peninsula led to the collapse of the Larsen A and B ice shelves in 1995 and 2002, respectively. There was then a period when some ice shelves in the eastern Antarctic grew in area (shown with a +).

The team of researchers from Cambridge University, Newcastle University, and New Zealand's University of Canterbury found that 85 per cent of the 870 mile-long (1,400km) ice shelf along the eastern Antarctic Peninsula 'underwent uninterrupted advance' between surveys of the coastline in 2003-4 and 2019.

Dr Frazer Christie, from Cambridge's Scott Polar Research Institute (SPRI) and the paper's lead author, said: 'We've found that sea ice change can either safeguard from, or set in motion, the calving of icebergs from large Antarctic ice shelves.

'Regardless of how the sea ice around Antarctica changes in a warming climate, our observations highlight the often-overlooked importance of sea ice variability to the health of the Antarctic Ice Sheet.'.

In 2019, Dr Christie and his co-authors were part of an expedition to study ice conditions in the Weddell Sea offshore of the eastern Antarctic Peninsula.

However, since 2020 there has been an increase in the number of icebergs breaking away from the eastern Antarctic Peninsula

If all the ice sheets were to melt due to global warming, Antarctica would raise global sea levels by at least 183ft (56m)

Using Nasa satellite imaging, researchers found that the oceanic phenomena cause Antarctic ice shelves to melt while also increasing snowfall.
