USA – MARIPOSA, Calif. (AP)
Fire investigators say gunfire caused a wildfire near Yosemite National Park that destroyed 131 structures, including 63 homes, last month.
The California Department of Forestry and Fire Protection said Friday that a gun fired on public lands caused the wildfire that burned 127 square miles (331 square kilometers) on July 16.
The fire, which prompted evacuations in several areas including the town of Mariposa, destroyed 63 homes and 67 other buildings.
CalFire is offering a $2,000 reward for information about the person responsible for starting the fire.
An international team of climate researchers from the US, South Korea and the UK has developed a new wildfire and drought prediction model for southwestern North America. Extending far beyond the current seasonal forecast, this study published in the journal Scientific Reports could benefit the economies with a variety of applications in agriculture, water management and forestry.
Over the past 15 years, California and neighboring regions have experienced heighteneddrought conditions and an increase inwildfire numbers with considerable impacts on human livelihoods, agriculture, and terrestrial ecosystems. This new research shows that in addition to a discernible contribution from natural forcings and human-induced global warming, the large-scale difference between Atlantic and Pacific ocean temperatures plays a fundamental role in causing droughts, and enhancing wildfire risks.
“Our results document that a combination of processes is at work. Through an ensemble modeling approach, we were able to show that without anthropogenic effects, the droughts in the southwestern United States would have been less severe,” says co-author Axel Timmermann, Director of the newly founded IBS Center for Climate Physics, within the Institute for Basics Science (IBS), and Distinguished Professor at Pusan National University in South Korea. “By prescribing the effects of man-made climate change and observed global ocean temperatures, our model can reproduce the observed shifts in weather patterns and wildfire occurrences.”
