00:57 New Iceberg Forms in Antarctica as Slab Breaks off Glacier Scientists aboard the British Antarctic Survey ship witnessed the dramatic moment a huge slab of ice broke off the William Glacier on Anver Island on the northern tip of Antarctica.

At a Glance A research base on the Antarctic Peninsula recorded a high of 65 degrees Fahrenheit Thursday.

This topped the all-time record for continental Antarctica, set in 2015.

A nearby station also set a February monthly record on Thursday.

A research station in Antarctica measured what could be the continent's all-time record high temperature, pending later verification.

Esperanza Base, an Argentine research station on the Trinity Peninsula, measured a high temperature of 65.1 degrees Fahrenheit on Thursday.

According to Argentina's National Meteorological Service, this is the warmest temperature on record anywhere on the continent , topping the previous record of 63.5 degrees from March 24, 2015.

The nearby Marambio Base also recorded the warmest February temperature on record Thursday, soaring to 60.4 degrees, smashing the previous February monthly record – 56.8 degrees – from Feb. 24, 2013, according to Etienne Kapikian, a meteorologist with Meteo France.

These temperatures will likely be investigated by a committee of the World Meteorological Organization. If confirmed, they would be accepted as new continental records for Antarctica.

"Everything we have seen thus far indicates a likely legitimate record, but we will of course begin a formal evaluation of the record once we have full data from SMN and on the meteorological conditions surrounding the event,” the WMO's Weather and Climate Extremes rapporteur, Randal Cerveny, told the Associated Press, referring to the acronym for Argentina’s weather service.

Even in mid-summer, temperatures typically don't stray far above or below freezing along the Antarctic Peninsula. High temperatures over the previous week at Esperanza Base ranged from about 33 to 44 degrees.

"The record appears to be likely associated (in the short-term) with what we call a regional 'foehn' event over the area," Cerveny told the AP, defining it as a rapid warming of air coming down a slope or mountain.

This 65-degree high temperature Thursday was roughly equal to the average high on Feb. 6 in Houston, San Diego, and Tallahassee, Florida.

The Antarctic Peninsula extends northeastward into the warmer Southern Ocean about 600 miles south-southeast of the tip of South America, Cape Horn.

According to the National Snow and Ice Data Center, the peninsula has warmed 4.5 degrees Fahrenheit since 1950.
