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 […]

For shrinking Mississippi River towns, frequent floods worsen fortunes – “Everybody’s gone. This is a ghost town.”

By Michael Phillis, Jim Salter, and Camille Fassett 11 June 2024 WEST ALTON, Missouri (AP) – Devastating flooding, driven in part by climate change, is taking an especially damaging toll on communities that once thrived along the banks of America’s most storied river. Flooding has pushed people out of their homes near the Mississippi River at […]

Global number of extreme wildfires, 2003-2023. The analysis of satellite data showed the number of extreme fires had risen by more than 10 times in the past 20 years in temperate conifer forests, such as in the western U.S. and Mediterranean. Data: Cunningham, et al., Nature Ecology & Evolution, 2024. The most extreme wildfires are in the top 0.1 percent of fires by radiative power, identified from 21 years of satellite data.

Climate crisis driving exponential rise in most extreme wildfires – Frequency of extreme events doubled from 2003 to 2023 – “This is the effect of what we’re doing to the atmosphere, so action is urgent”

By Damian Carrington 24 June 2024 (The Guardian) – The climate crisis is driving an exponential rise in the most extreme wildfires in key regions around the world, research has revealed. The wildfires can cause catastrophic loss of human life, property and wildlife and cause billions of dollars of damage. Scientists say this is climate […]

2024’s violent tornado season has been one of the most active on record

By William Gallus 26 June 2024 (The Conversation) – Spring 2024 was unnerving for people across large parts of the U.S. as tornado warnings and sirens sent them scrambling for safety. More than 1,100 tornadoes were reported through May − a preliminary number but nearly twice the 30-year average at that point and behind only 2011, when deadly […]

Number of unique book titles challenged in the U.S., 2000-2023. The number of titles targeted for censorship surged 65 percent in 2023 compared to 2022, reaching the highest levels ever documented by the American Library Association (ALA). The numbers show efforts to censor 4,240 unique book titles in schools and libraries. This tops the previous high from 2022, when 2,571 unique titles were targeted for censorship.
