The quantity of sea ice round Antarctica is at a document low for the top of June, the Met Workplace has stated.

It’s considerably beneath the earlier document, by 1.3 million sq km (501,930 sq miles) – an space greater than 5 instances that of the UK.

Dr Ed Blockley, who leads the forecaster’s Polar Local weather Group, stated: “Antarctic sea ice extent reaches a most across the finish of September and a minimal across the finish of February.

“On the finish of June, the extent of sea ice ought to be constructing to a mid-point between the utmost and the minimal.

“Nonetheless, this 12 months the ice is increasing very slowly with the consequence that the extent is method beneath the long-term (1981-2010) common.

“The annual minimal extent in February 2023 was the bottom since satellite tv for pc information started in 1979, simply over a million sq km beneath the long-term common.

“The present extent is very low: it’s in extra of two.5 million sq km (965,255 sq miles) beneath common for the time of 12 months.”

El Nino, a phenomenon which heats up the japanese Pacific Ocean, combined with anomalous atmospheric circulation patterns round Antarctica, might be stopping ice from recovering through the winter, in response to some specialists.

Southern continent temperatures will proceed to fall as winter continues, which ought to give the ice extra time to increase.

Dr Blockley stated: “It’s too early to invest whether or not ice extent will stay at extraordinarily low ranges.

“There may be nonetheless time this season for the ice to recuperate however given the document lows we now have seen we now have to stay involved concerning the probability of a document low winter most.”

Earlier this month, the dramatic modifications to the polar ice caps brought on by climate change were reflected in a brand new version map of Antarctica and the Arctic.

Produced by cartographers on the British Antarctic Survey (BAS), the flagship printed map wants updating repeatedly to maintain monitor of the quickly altering environments.

In February, scientists issued a warning that Antarctica’s huge Thwaites glacier might push up international sea ranges by half a metre due to its melting ice.

They detected a vital level in Thwaites’ chaotic breakup, “the place it is melting so shortly there, there’s simply materials streaming out of the glacier,” stated robotic creator and polar scientist Britney Schmidt of Cornell College, New York.
