A derecho swept through parts of Iowa, South Dakota, Nebraska, Illinois, and Minnesota on July 5. South Dakota experienced fallen power lines and trees from wind gusts higher than 90 mph. Huron and Miner, states in South Dakota, had wind gusts higher than 95 mph. The derecho that swept intense wind through the Midwest may be linked to climate change.
The derecho on July 5 is a progressive derecho, a summertime-occurring derecho fueled by an area that is hot, dry, and contains strong winds. A similar occurrence happened in August of 2020 when a derecho with extremely high winds hit over 700 miles in 14 hours across the Midwest destroying crops, homes, trees, and more. Meteorology professor at the University of Northern Iowa Alan Czarnetzki said, after the 2020 derecho, human-induced warming of the planet’s surface can increase the likelihood of stronger derechos.
After the derecho on July 5, scientists also say climate change can increase the intensity of storms like derechos. According to NASA, as the air continues to warm from climate change, other storms including hurricanes may also be affected, creating heavier rainfall and stronger wind.
In 2021, the world’s surface temperature was 1.51 degrees Fahrenheit warmer than the 20th century average of 57 degrees Fahrenheit.
