While greenhouse gases continue to cause temperatures to rise, a reduction in low-cloud cover over land serves as a natural brake: study.

As people in Los Angeles went through the day on January 6, 2025, NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) sensor performed hourly east-to-west scans of North America. 

Salt pollution in freshwater is a growing global concern.

By editing the polymers of discarded plastics, chemists at the Department of Energy’s Oak Ridge National Laboratory have found a way to generate new macromolecules with more valuable properties than those of the starting material.

As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to “geoengineer” climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect.

Wildfires increasingly threaten public drinking water systems, but guidance on how to address damage to these systems from a wildfire has been insufficient, conflicting or inaccurate. 

Carbon dioxide is accumulating in the atmosphere faster than ever before, putting hopes of limiting warming in jeopardy.

Longer, more diverse rotations of crops fertilized with livestock manure have many environmental benefits, but carbon sequestration isn’t one of them, according to a new study led by Iowa State University researchers.

Construction materials such as concrete and plastic have the potential to lock away billions of tons of carbon dioxide, according to a new study by civil engineers and earth systems scientists at the University of California, Davis and Stanford University. 

As part of an international project consortium, TU Graz has developed new measurement techniques and methods to measure emissions from category-L vehicles in realistic operation and to determine corresponding limit values.
