An international coalition of researchers says in a report published this week that the Earth’s vital signs have worsened to the point that “humanity is unequivocally facing a climate emergency.”

This year La Niña returns for the third consecutive winter, and starting in December 2022 through February 2023, NOAA predicts drier-than-average conditions across the South with wetter-than-average conditions for areas of the Ohio Valley, Great Lakes, northern Rockies and Pacific Northwest, according to NOAA’s U.S. Winter Outlook released today by the Climate Prediction Center — a division of the National Weather Service.

Forecasters are predicting a “three-peat La Niña” this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that’s happened only twice before in records going back to 1950.

The number of trout in a southern Oregon stream system showed no decline one year after a fire burned almost the entire watershed, including riparian zone trees that had helped maintain optimal stream temperatures for the cold-water fish.

The U.S. effort to build a domestic supply of clean energy often begins with critical materials produced in far-off — and geopolitically sensitive — countries. Researchers at the U.S. Department of Energy’s Argonne National Laboratory recently contributed to a series of reports aimed at securing America’s clean energy supply chain and minimizing potential disruptions. 

Global fish stocks will not be able to recover to sustainable levels without strong actions to mitigate climate change, a new study has projected.

As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park, a stunning jewel about two hours south of Anchorage.

California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state’s climate-change solution arsenal may be in jeopardy, as new research from the University of California, Irvine reports that trees in California’s mountain ranges and open spaces are dying from wildfires and other pressures – and fewer new trees are filling the void.
