Hottest day on record in Antarctica as temperature hits 18 degrees
Some 87% of glaciers along west coast have retreated over the past 50 years

The continent of Antarctica has experienced its hottest temperature on record, with a research station provisionally recording 18.3 degrees.
The reading beats the previous record on the earth’s southernmost continent of 17.5 degrees in March 2015, according to the Argentine station Esperanza, which collected the data.
The tweet reporting the news from Argentina’s meteorological association was shared by the United Nations’s World Meteorological Organisation (WMO).
The Antarctic Peninsula, the northwest tip near South America, is among the fastest warming regions on earth, with temperatures rising almost 3 degrees over the past 50 years, the WMO said.
Some 87 per cent of the glaciers along its west coast have “retreated” over those five decades and have shown an “accelerated retreat” in the past 12 years, it added.
He told the paper: “The reading is impressive as it’s only five years since the previous record was set and this is almost one degree centigrade higher. It’s a sign of the warming that has been happening there that’s much faster than the global average.
“To have a new record set that quickly is surprising but who knows how long that will last? Possibly not that long at all.”
Esperanza, located near the northern tip of the Peninsula, has been collecting data since 1961.
The reading breaks the 2015 record for the Antarctic continent, defined as the main continental landmass and adjoining islands by the WMO.
The record for the Antarctic region — defined as all land and ice south of 60 degrees latitude — is 19.8 degrees recorded on Signy Island in January 1982, the WMO said. – PA
