Arctic and Antarctic have Simultaneous heat Wave
Both of Earth’s polar regions recently experienced unprecedented simultaneous heat waves that caused temperatures to briefly skyrocket to never-before-seen heights in some areas. While experts say such extreme temperatures cannot be solely attributed to climate change, the unusual phenomenon is nonetheless “dramatic” and “alarming.”
In Antarctica on Friday (March 18), the average temperature was 8.6 degrees Fahrenheit (4.8 degrees Celsius) warmer than average. The highest recorded temperature was 44.6 F (7 C) at the coastal Zucchelli Station on Terra Nova Bay. The biggest temperature difference was recorded at Concordia Research Station, located more than 10,000 feet (3,000 m) above sea level, where researchers measured a peak temperature of 10 F minus 12.2 C), which is 70 F (nearly 40 C) above the seasonal average at the station.
In the Arctic, the average temperature on the same day was 6 F (3.3 C) higher than normal, and in certain areas near the North Pole temperatures rose by 50 F (30 C) above normal.
It is very uncommon to see high temperatures across both polar regions at the same time because they have contrasting seasons; as spring arrives in the Northern Hemisphere, the Arctic is just starting to thaw while Antarctica is beginning to freeze after months of summer melt.
