Antarctic sea ice at file low for finish of June, says Met Office
It is 1.3 million sq km (501,930 sq miles) beneath the earlier low file for this time of yr, an quantity that’s greater than 5 instances the floor space of the UK.
Dr Ed Blockley, who leads the Met Office’s Polar Climate Group, mentioned: “Antarctic sea ice extent reaches a maximum around the end of September and a minimum around the end of February.
“At the end of June, the extent of sea ice should be building to a mid-point between the maximum and the minimum.
“However, this year the ice is expanding very slowly with the consequence that the extent is way below the long-term (1981-2010) average.
“The annual minimum extent in February 2023 was the lowest since satellite records began in 1979, just over one million sq km below the long-term average.
“The current extent is extraordinarily low: it is in excess of 2.5 million sq km (965,255 sq miles) below average for the time of year.”
Scientists imagine that El Nino, a cyclical phenomenon which warms the tropical jap Pacific Ocean and impacts air temperatures worldwide, and anomalous atmospheric circulation patterns round Antarctica, might be stopping the ocean ice from recovering as a lot because it often does in winter.
Temperatures on the southern continent will proceed to fall as winter advances which can give the ice extra time to increase additional.
Dr Blockley mentioned: “It is too early to speculate whether ice extent will remain at extremely low levels. There is still time this season for the ice to recover but given the record lows we have seen we have to remain concerned about the likelihood of a record low winter maximum.”
