MAMMOTH LAKES, CA - JULY 28: An aerial view of a forest killed by carbon dioxide near drought-shrunken Horseshoe Lake which may again release deadly levels of the greenhouse gas carbon dioxide, on July 28, 2022 near Mammoth Lakes, California. During a series of earthquakes in 1989 and 1990, magma movement opened underground cracks that began releasing Carbon dioxide (CO2) gas that killed a nearby section of forest. The invisible, odorless and tasteless gas is heavier than air and tends to settle over the lake and in snow, and could quickly prove deadly to humans in large amounts. The overwhelming majority of climate-effecting greenhouse gas emissions by humans is carbon dioxide. (Photo by David McNew/Getty Images)

Warming temperatures are creating 'zombie forests' in California

A fifth of conifer forests in California’s Sierra Nevada mountains are now in places that are too hot for them – meaning they may not regrow if wiped out by wildfire or disease
