Benefits of enhanced weathering for surface ozone and crop production. Credit: Nature (2025). DOI: 10.1038/s41586-024-08429-2 A new study reveals that implementing enhanced weathering (EW), the practice of adding crushed basalt to soils, with U.S. agriculture could remove between 160 and 300 million metric tons of carbon dioxide (CO2) from the …

3D ocean model shows ocean acidification moving deeper as atmospheric emissions increase
Global mean sections of the absolute state of the marine CO2 system in 2014 and changes from 1800 to 2014. Panel rows distinguish the saturation state of aragonite (Ωarag). Credit: Science Advances (2024). DOI: 10.1126/sciadv.ado3103 A pair of environmental physicists at the Institute of Biogeochemistry and Pollutant Dynamics, ETH Zurich, …
Atmospheric observations in China show rise in emissions of a potent greenhouse gas
Emissions of SF6 in China. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-46084-3 To achieve the aspirational goal of the Paris Agreement on climate change—limiting the increase in global average surface temperature to 1.5 degrees Celsius above preindustrial levels—will require its 196 signatories to dramatically reduce their greenhouse gas (GHG) emissions. Those …
Climate change isn’t producing expected increase in atmospheric moisture over dry regions: Study
Credit: Pixabay/CC0 Public Domain The laws of thermodynamics dictate that a warmer atmosphere can hold more water vapor, but new research has found that atmospheric moisture has not increased as expected over arid and semi-arid regions of the world as the climate has warmed. The findings are particularly puzzling because …
Farmers and ranchers in the Southwestern US face challenges due to human-induced atmospheric warming
Map of study region and extent of 2020 drought. The study region is shown in black, encompassing portions of Utah, Colorado, New Mexico, and Arizona. Extent of USDM drought classifications for 29 December 2020 are shown as well. Credit: Earth’s Future (2023). DOI: 10.1029/2022EF002943 The American Southwest has always been …
Study sheds light on toxicity of atmospheric particulate matter pollution
Aerosol chemical measurements and sample collections were conducted at the SEARCH network site at Jefferson Street in Atlanta, Georgia. Credit: Georgia Institute of Technology Each year, exposure to airborne particulate matter known as PM2.5 (particles with a diameter smaller than 2.5 micrometers) leads to millions of premature deaths worldwide. Organic …
New finding provides better understanding of oceans’ capacity to absorb atmospheric carbon dioxide
Satellite PIC and location map. August satellite-derived Particular Inorganic Carbon (PIC; mg CaCO3 m-3) climatology (2002-2017) and location of C-DisK-IV stations (black crosses) and long-term sediment trap studies (orange/pink crosses). Large black crosses show the location of Niskin bottle rosette, plankton tow, and floating sediment trap sampling sites at C-DisK-IV …
