Map showing reduction of stored groundwater in the U.S. Southwest, April 2002 - September 2023. Gravity measurements from the GRACE series of satellites show that the decline in water levels in the Great Basin region from April 2002 to September 2023 has most severely affected portions of southern California (indicated in red). Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest.

NASA satellites find record snow didn’t offset Southwest U.S. groundwater loss – “In years like the 2022-23 winter, I expected that the record amount of snowfall would really help to replenish the groundwater supply. But overall, the decline continued.”

By James R. Riordon 17 June 2024 (NASA GSFC) – Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data [Snowfall Replenishes Groundwater Loss in the Great Basin of the Western United States, but […]

Climate change made killer heat wave in Mexico, Southwest U.S. even warmer and 35 times more likely – “The changes we have seen in the last 20 years, which feels like just yesterday, are so strong”

By Seth Borenstein 20 June 2024 WASHINGTON (AP) – Human-caused climate change dialed up the thermostat and turbocharged the odds of this month’s killer heat that has been baking the Southwestern United States, Mexico and Central America, a new flash study found. Sizzling daytime temperatures that triggered cases of heat stroke in parts of the United States were […]

“Catastrophic flooding” in Upper Midwest U.S. prompts evacuations as record-breaking heat wave broils the West and mid-Atlantic – “The river rose to historic levels that we’ve never seen here before”

By Dalia Faheid 23 June 2024 (CNN) – Millions of people across the US are still trudging through a record-setting heat wave that is shifting to the Mid-Atlantic, while many Americans – including in New Mexico, Iowa, Minnesota, and South Dakota – contend with “catastrophic” flash flooding this weekend. Here’s the latest: Flooding threat in northern […]

Heat-related deaths in the U.S., 1979-2023. A heat wave in July of 2023 contributed to a higher recorded death toll — about 2,300 people in total — than historic heat waves in 1980 and 1995. Data: National Center for Health Statistics, CDC Wonder. Graphic: M.K. Wildeman / AP

2023 set record for U.S. heat deaths, killing in areas that used to handle the heat – “We can be confident saying that 2023 was the worst year we’ve had since we’ve started having reliable reporting on that”

By Seth Borenstein, Mary Katherine Wildeman, and Anita Snow 31 May 2024 (AP) – David Hom suffered from diabetes and felt nauseated before he went out to hang his laundry in 108-degree weather, another day in Arizona’s record-smashing, unrelenting July heat wave. His family found the 73-year-old lying on the ground, his lower body burned. Hom […]

Extreme heat in North America, Europe, and China in July 2023 made much more likely by global warming – Without human-induced climate change these heat events would have been extremely rare: China heatwave would have been a 1 in 250-year event, and max heat like in July 2023 would have been virtually impossible in the U.S./Mexico region and Southern Europe

25 July 2023 (World Weather Attribution) – Following a record hot June, large areas of the US and Mexico, Southern Europe and China experienced extreme heat in July 2023, breaking many local high temperature records. July 2023 saw extreme heatwaves in several parts of the Northern Hemisphere, including the Southwest of the US and Mexico, […]

A wet winter won’t stave off the Colorado River’s water cuts – “There are discussions going on but they’re not making much progress. The level of distrust and animosity is really remarkable.”

By Joshua Partlow 3 April 2023 GRAND JUNCTION, Colorado (The Washington Post) – The abundant snow in the Rocky Mountains this year has been a welcome relief, but is not enough to overcome two decades of drought that has pushed major reservoirs along the Colorado River down to dangerous levels, Camille Calimlim Touton, the commissioner […]

Drought has reduced the water level in Lake Mead so much that Southern Nevada Water Authority's original water intake valve in Lake Mead -- in service since 1971 -- was visible above the water line in April 2022. The original intake is no longer in use since it cannot draw water. Photo: Southern Nevada Water Authority

Lake Mead plummets to record low, exposing original 1971 water intake valve – Dead man found in barrel at lake bottom, authorities say more bodies likely to turn up – “This is a crisis. This is unprecedented.”

By Stephanie Elam 29 April 2022 (CNN) – The U.S. West is in the grips of a climate change-fueled megadrought, and Lake Mead — the largest manmade reservoir in the country and a source of water for millions of people — has fallen to an unprecedented low. The lake’s plummeting water level has exposed one of the reservoir’s original water […]
