Scientists warn of warmer, eastward shifting supercells in US
A new study in the Bulletin of the American Meteorological Society projects a 6.6 percent rise in supercells and a 25.8 percent growth in the area and time they reach peak strength by century’s end. The pattern shows more frequent nighttime storms in the densely populated Deep South including Alabama, Mississippi and Tennessee, with Rolling Fork cited as a local example. The research uses regional computer models to forecast where and when more violent storms will occur under moderate to severe warming, noting an eastward shift and greater risk to poorer communities with mobile homes. Lead author Walker Ashley and co author Victor Gensini of Northern Illinois University emphasize this is a projected trend, not a single event, though the Mississippi tornado aligns with the pattern.

Renewable energy growth must surge to meet climate goals
IRENA says end of decade push needed as wind and solar accounted for most new power last year. Global renewables hit 40 percent of capacity in 2022, but emissions targets require more than doubling deployment and shifting fossil investments. Substantial investment and aid to developing nations urged.

Global Wind Energy Growth Seen Accelerating in 2023 Explained
The Energy Information Administration projects wind share rising to 12 percent and solar to 5 percent of U.S. electricity from 2022 to 2023, with natural gas stable at 39 percent and coal down to 17 percent. The Global Wind Energy Council cautions that wind can meet only part of demand without storage and grid upgrades, despite 2023 forecasted rapid expansion driven by the Inflation Reduction Act and policy support worldwide.
