Physicist Stephen Volz had been working with colleagues at the U.S.’s National Oceanic and Atmospheric Administration for nearly 10 years to produce a new generation of geostationary satellites — instruments that would provide critical observations about atmospheric conditions, climate patterns and weather. But when Donald Trump returned to office in January 2025, this long-term project was thrown into disarray. “This administration canceled three of the five instruments on that program,” Volz, the assistant administrator for NOAA’s National Environmental Satellite, Data, and Information Service, who has been on administrative leave since July 2025, told Mongabay. The cancellations applied to instruments that measured air pollutants, tracked lightning to forecast hurricanes and tornadoes, and monitored ocean color to detect events such as algal blooms, sargassum seaweed surges and salinity changes, according to Volz. “They said, ‘those are all wasted money, they’re climate alarmist, I don’t need air quality, I don’t need ocean color,’” Volz said about the administration’s decision. The axing of this project is just one example of what experts describe as a broad, long-term effort by the Trump administration to weaken NOAA. The long-standing scientific and regulatory agency within the U.S. Department of Commerce has historically been responsible for everything from forecasting the weather and monitoring the climate to managing fisheries and protecting marine mammals. The White House did not respond to Mongabay’s request for comment.

Globally, about half of drinking water and a quarter of irrigation water comes from under the ground. Yet many coastal sites throughout the world are seeing notable declines in their groundwater levels, putting them at risk of saltwater intrusion, a new study says. The study, published April 14 in the journal Nature Water, found that more than 10% of monitored locations showed a significant years-long decline in groundwater levels, indicating a susceptibility to saltwater intrusion, which can render water unusable. Annika Nolte, a data scientist at the University of Bremen in Germany and lead author of the study, said the results amounted to a “warning” and the work offered a “broad global look at the existing risks” while also identifying “specific regions where we should prioritize management and monitoring.” Sections of a cornfield in the eastern United States.

Groundwater’s role as a key source of freshwater makes it essential for human existence, according to co-author Robert Reinecke, a professor of earth sciences at Johannes Gutenberg University Mainz in Germany. “Generally speaking, the availability of drinking water is a prerequisite for people to be able to live anywhere, grow food, and for us to have healthy ecosystems,” Reinecke told German news program Tagesschau.
