A report warns that carbon dioxide levels are set to rise sharply this year as a powerful El Niño intensifies, with the climate pattern expected to weaken carbon sinks and boost emissions. The warning is being shared widely in environmental and science circles, with readers highlighting it as another sign of the escalating climate crisis.

Researchers report that snowstorms are depositing microplastics on remote, high-altitude areas of California's Sierra Nevada mountains. The most common plastics identified in the snowpack were polyethylene and polypropylene, widely used in packaging, along with polyester fibers. The finding shows plastic pollution is now reaching even isolated mountain regions, likely carried long distances through the atmosphere before falling with precipitation.
