A new study shows hot, dry and windy weather that fuels extreme wildfires has nearly tripled worldwide in 45 years.

A quick scientific study finds that human-caused climate change increased the likelihood and intensity of the hot, dry and windy conditions that fanned the flames of the recent devastating Southern California wildfires.

Here's what experts say is turning Southern California's speedy wildfires into a deadly urban conflagration that is defying the calendar.

Forecasters say the only break much of America can hope for anytime soon from eye-watering dangerous smoke from fire-struck Canada is brief bouts of shirt-soaking sweltering heat and humidity from a southern heat wave that has already proven deadly.

Gavin Newsom said the amount of land scorched by the August Complex is larger than all of the recorded fires in California between 1932 and 1999. Since the beginning of the year, more than 8,200 California wildfires have scorched “well over 4 million acres” or 6,250 square miles, the California Department of Forestry and Fire Protection said Sunday in a statement. Numerous studies have linked bigger wildfires in America to climate change from the burning of coal, oil and gas. Scientists say climate change has made California much drier, meaning trees and other plants are more flammable.
