Global warming makes tropical soils leak carbon dioxide

Tropical forest soil warmed in experiments to levels consistent with end-of-century temperature projections released 55 percent more CO2 than control plots, exposing a previously underestimated source of greenhouse gas emissions, ...

A warming California sets the stage for future floods

By the 2070s, global warming will increase extreme rainfall and reduce snowfall in the Sierra Nevada, delivering a double whammy that will likely overwhelm California's reservoirs and heighten the risk of flooding in much ...

How airplanes counteract St. Elmo's Fire during thunderstorms

At the height of a thunderstorm, the tips of cell towers, telephone poles, and other tall, electrically conductive structures can spontaneously emit a flash of blue light. This electric glow, known as a corona discharge, ...

Peatland carbon and nitrogen stocks vulnerable to permafrost thaw

Northern peatlands hold large stocks of carbon and nitrogen and thus play a key role in global climate dynamics. However, their vulnerability to climate warming is uncertain, due in part to a lack of spatially explicit, observation-based ...
