New timeline of deadliest California wildfire could guide lifesaving research and action
On a brisk November morning in 2018, a fire sparked in a remote stretch of canyon in Butte County, California, a region nestled against the western slopes of the Sierra Nevada mountains. Fueled by a sea of tinder created by…
Climate change: Erratic weather slows down the economy
If temperature varies strongly from day to day, the economy grows less. Through these seemingly small variations climate change may have strong effects on economic growth. This shows data analyzed by researchers from the Potsdam Institute for Climate Impact Research…
Variable weather makes weeds harder to whack
URBANA, Ill. – From flooded spring fields to summer hailstorms and drought, farmers are well aware the weather is changing. It often means spring planting can’t happen on time or has to happen twice to make up for catastrophic losses…
Arctic stew: Understanding how high-latitude lakes respond to and affect climate change
To arrive at Nunavut, turn left at the Dakotas and head north. You can’t miss it–the vast tundra territory covers almost a million square miles of northern Canada. Relatively few people call this lake-scattered landscape home, but the region plays…
California’s rainy season starting nearly a month later than it did 60 years ago
WASHINGTON–The start of California’s annual rainy season has been pushed back from November to December, prolonging the state’s increasingly destructive wildfire season by nearly a month, according to new research. The study cannot confirm the shift is connected to climate…
