National Geographic reports:

Scientists have measured what is likely the highest temperature ever on Antarctica: 63.5 degrees Fahrenheit (17.5 Celsius).The measurements were made last Tuesday at Argentina’s Esperanza Base, on the northern tip of the Antarctic Peninsula, according to the meteorological website Weather Underground. The previous hottest known temperature on the continent was 62.8°F (17.1°C), recorded at Esperanza Base on April 24, 1961.

The Weather Underground called last week’s temperatures a “remarkable heat wave,” although they occurred during the end of the austral summer, when Antarctic temperatures are typically highest.

The temperature has yet to be certified as an official record for the continent by the World Meteorological Organization.

It’s hard to draw much conclusion from a single temperature record, cautions Gavin Schmidt, a climate scientist with NASA’s Goddard Institute for Space Studies in New York City. Last year Antarctica also logged a record cold temperature, he notes.

And what does our Senate Majority leader say to the world about the undeniable climate change that has been observed by 99 % of scientists?

“Considering that two-thirds of the U.S. federal government hasn’t even signed off on the Clean Power Plan and 13 states have already pledged to fight it, our international partners should proceed with caution before entering into a binding, unattainable deal.”
