David Boutt, UMass Amherst (from The Conversation) About two-thirds of the U.S. is in some stage of drought in late spring 2026, yet at the same time the country has been seeing more intense downpours. It might seem contradictory, but both are symptoms of rising global temperatures. The reason has to do with the water cycle. Water influences every aspect of our lives through a…

[PDF] [Cited by] “Recent record-hot years have caused discussion over whether global warming has accelerated. Previous analysis found acceleration (i.e., increase in warming rate) has not yet reached a 95% confidence level, given natural temperature variability. We remove the estimated influence of three main natural variability factors:…

Background: “Critics have long claimed that variable renewables are too unreliable: The wind doesn’t always blow, and the sun doesn’t always shine. But evidence shows that intermittency concerns are now generally unfounded. Ten proven carbon-free balancing methods already make high-renewable grids reliable and economic in many countries. One of those methods, batteries, costs 96% less today than it did in 2010. BloombergNEF finds that battery-firmed solar and…

Renee Obringer, Penn State and Dave White, Arizona State University (from The Conversation) When a drought turns into an urban water crisis, a city’s first step is often to limit lawn watering and launch a campaign to encourage everyone to conserve. It might raise water-use rates or offer incentives for installing low-flow devices. While demand management techniques like these have had a lot of success…

Multiple studies from different regions around the world show bird and insect populations declining precipitously. Are these declines connected? What has caused them? And what are the consequences for human society? Would it be possible for us to help birds and insects flourish again? See the research … References: *Leroy, F., Jarzyna, M. A., & Keil, P. (2026).

Michael Wysession, Washington University in St. Louis (from The Conversation) The past three years have been the world’s hottest on record by far, with 2025 almost tied with 2023 for second place. With that energy came extreme weather, from flash flooding to powerful hurricanes and severe droughts. Yet, by most indicators, the planet should have been cooler in 2025 than it was. So, what happened,…

Shuang-Ye Wu, University of Dayton (from The Conversation) A powerful storm system that stalled over states from Texas to Ohio for several days in early April 2025 wreaked havoc across the region, with deadly tornadoes, mudslides and flooding as rivers rose. More than a foot of rain fell in several areas. As a climate scientist who studies the water cycle, I often get questions about…

Earth’s climate is changing rapidly. No, it is not a hoax, not a projection for the future, not a scare tactic from whatever political or advocacy group that you or your favorite politician may not like. In our lifetimes, it has changed–generally growing warmer and often dryer, with daily weather more prone to extremes–winds, rain, snow, cold, heat, more destructive storms leading to more extensive…
