Even before summer officially begins, signs are mounting that large swaths of North America, Europe and Asia will be gripped by intensifying heat waves, flooding and storms, according to climate scientists and meteorological forecasters cited by Bloomberg. “I’d expect to see further instances of extreme to record-shattering downpours and flood events in regions prone to heavy precipitation during the warm season,” said Daniel Swain, climate scientist at UCLA. In the U.S., Bloomberg reports that heat domes forming across the western and central regions could trap high temperatures in place, while jet stream distortions downstream may lock in rain systems, triggering widespread flooding. Meanwhile, Paul Pastelok of AccuWeather warned that “the bends in the jet stream may increase the threat of derechos” — long-track severe thunderstorms — across the Midwest and Northern Plains, potentially inflicting billions in damages. In the Atlantic, warmer ocean temperatures are raising the risk of a more intense hurricane season, with Texas and the Gulf Coast particularly exposed, Bloomberg noted.
The report also highlighted severe infrastructure and agricultural stress:
- 89 million Americans across three power grids are at elevated risk of electricity shortfalls this summer, per the North American Electric Reliability Corp.
- Intensifying drought in the Corn Belt may impact corn, soybeans and wheat, and could cause Mississippi River levels to fall, disrupting barge traffic.
In Europe, persistent high-pressure systems are expected to reduce rainfall, increasing drought risks and suppressing wind energy generation — a trend that earlier in the year saw record-high solar output but low wind yields.
Bottom line according to Bloomberg: “The Northern Hemisphere’s summer hasn’t officially started, but signs are already piling up that... [it] will be pummeled by record heat and other weather extremes.”
