Satellite image of Sau Reservoir captured on March 3, 2023, by Landsat 9.Satellite image of Sau Reservoir captured on March 4, 2024, Landsat 8.The large reservoir in Catalonia shrank to 1 percent of capacity in March 2024.Three subsequent years of record low precipitation have taken a toll on northeastern Spain’s Catalonia region. Satellite images show one of the region’s largest reservoirs dried to a trickle in March 2024.Historical Drought Patterns and Current ImpactAccording to the Meteorological Service of Catalonia,…

The world just experienced its hottest January on record, but that wasn't the only new record it set, the European Union's Copernicus Climate Change Service (C3S) said on Thursday.For the first time, the global temperature pushed past the internationally agreed upon warming threshold for an entire 12-month period, with February 2023 to January 2024, running 1.52 C, according to C3S.Last month surpassed the previous warmest January, which occurred in 2020, in C3S's records going back to 1950.Every month since June has been…

The European Space Agency’s (ESA) spacecraft, the Mars Express, has located a Martian water reservoir that is almost two miles deep. The reservoir is made up of water ice, which, if melted, could cover the entire planet in a layer of water 1.5 to 2.7 meters deep, the ESA estimates.This reservoir is the most ice ever found in the equatorial area of Mars, the ESA says, and future studies of the surface of the Red Planet, as well as the area where these reservoirs are, could help provide more insight into Mars’s…

After a year of record-breaking wildfires across Canada and the hottest temperature ever recorded on Earth, it likely comes as no surprise that 2023 was the hottest year on record.According to the European Union's Copernicus Climate Change Service (C3S), 2023 was 1.48 C warmer than the pre-industrial average from 1850-1900, beating out 2016's record of 1.25 C.

Carbon storage has been a key focus in recent years to draw down natural and anthropogenic sources of carbon dioxide and help the fight against global warming, and particularly focuses on terrestrial forests and soils, as well as wetland mangroves and seagrasses.…

Satellite image of Lake Powell acquired on September 23, 2022, by the Operational Land Imager 2 on Landsat 9.Satellite image of Lake Powell acquired on October 20, 2023, by the Operational Land Imager on Landsat 8.A wet winter in western states provided a short-term reprieve to the decades-long drought in the reservoir.After falling to record lows in early 2023, water levels in Lake Powell—the second-largest reservoir in the United States—rebounded in the summer of 2023. Above-average snowmelt from the Rocky Mountains…

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has found that SARS-CoV-2, the virus causing COVID-19, has widely spread within the U.S. white-tailed deer population, possibly transmitted from humans to deer, where it mutated and potentially transmitted back to humans. The findings are part of a study involving the surveillance of over 11,000 white-tailed deer.USDA’s APHIS research indicates that <span class="glossaryLink" aria-describedby="tt"…
