Burned out vehicles sit under a burned tree at a residence in Vacaville, California during the LNU Lightning Complex fire on August 19, 2020. - California was in a state of emergency on August 19, 2020 as dozens of fast-moving fires, many triggered by lightning strikes during an extreme heat wave, spread across the north and centre of the state, threatening homes and causing the evacuation of thousands of people. About 20 fires broke out in the area of Vacaville in the northern Bay Area, emergency services said, and were being collectively called the LNU Lightning Complex fire after the intense lightning storm that sparked the conflagration earlier in the week. Scientists predict an increase in such natural disasters and climate-induced issues, should global temperatures continue to spike. PHOTO: JOSH EDELSON / AFP
