Antarctica Experiences First Known Heat Wave

Scientists have recorded Antarctica's first documented heat wave, warning that animal and plant life on the isolated continent could be drastically affected by climate change. Australian Antarctic Program researchers recorded the heat wave event at Casey research station in East Antarctica during the 2019-2020 southern hemisphere summer. Findings by the team were published in the Global Change Biology journal on Tuesday, with authors warning that the changes could affect global weather patterns. Between January 23 and 26, a research team at Casey — directly south of Perth in western Australia — recorded the highest maximum and minimum temperatures ever seen at the base. During the period, minimum temperatures were higher than zero degrees Celsius (32 degrees Fahrenheit) while the maximums peaked above 7.5 degrees. On January 24, the Casey team recorded a record high temperature of 9.2 degrees Celsius, 6.9 degrees higher than the station's mean maximum. Read more...
