Housing and Development Newsletter Using state-of-the-art climate model simulations available from NCAR, the researchers analyzed the climate under various combinations of climate influences from 1920-2100, allowing them to isolate individual effects and their impacts on extreme fire weather risk. According to the study, heat-trapping greenhouse gas emissions (which started to increase rapidly by mid- 20th century) are the dominant contributor to temperature increases around the globe. By 2005, emissions raised the risk of extreme fire weather by 20% from preindustrial levels in western and eastern North America, the Mediterranean, Southeast Asia and the Amazon. The researchers predict that by 2080, greenhouse gas emissions are expected to raise the risk of extreme wildfire by at least 50% in western North America, equatorial Africa, Southeast Asia and Australia, while doubling it in the Mediterranean, southern Africa, eastern North America, and the Amazon. ....
E-Mail When the Thomas Fire raged through Ventura and Santa Barbara counties in December 2017, Danielle Touma, at the time an earth science researcher at Stanford, was stunned by its severity. Burning for more than a month and scorching 440 square miles, the fire was then considered the worst in California s history. Six months later the Mendocino Complex Fire upended that record and took out 717 square miles over three months.

The disturbing trend sparked some questions for Touma, who is now a postdoctoral researcher at UC Santa Barbara s Bren School for Environmental Science & Management. ....
