Unprecedented Heat Wave Sweeps Antarctica, Scientists Discover

Scientists have discovered the most intense heat wave ever recorded on Earth, occurring in March 2022 near the eastern coast of Antarctica. Temperatures spiked 70 degrees Fahrenheit (39 degrees Celsius) above normal, with researchers on-site experiencing unusually warm conditions. The heat wave was attributed to a combination of natural variability and the warming climate, with unusual winds allowing warm air from southern Australia to move to East Antarctica. While the complete role of climate change is still being investigated, the study suggests that it only increased the heat wave by 2 degrees Celsius, but by the end of the century, it could boost such events by an additional 5 to 6 degrees Celsius. The occurrence of more heat waves in a warmer world could have significant impacts on the Antarctic ice sheet.
