1 00:00:04,770 --> 00:00:10,480 In 2018, California was already in its 6th consecutive year of drought 2 00:00:10,480 --> 00:00:16,630 setting the stage for the Camp Fire, the most destructive fire in California’s history. 3 00:00:16,630 --> 00:00:19,050 4 00:00:19,050 --> 00:00:22,470 The fire burned an area larger than the city of Chicago 5 00:00:22,470 --> 00:00:26,650 and destroyed 14,000 buildings. 6 00:00:26,650 --> 00:00:30,120 We usually think of climate change in the context of more flooding 7 00:00:30,120 --> 00:00:32,000 more intense hurricanes, 8 00:00:32,000 --> 00:00:34,440 and rising sea levels. 9 00:00:34,440 --> 00:00:36,880 But some areas of the world are forecasted to 10 00:00:36,880 --> 00:00:40,650 get drier and hotter as the climate warms up. 11 00:00:40,650 --> 00:00:42,170 Fire needs two things: 12 00:00:42,170 --> 00:00:47,140 enough fuel and fuel that’s dry enough to catch fire. 13 00:00:47,140 --> 00:00:51,500 More droughts probably mean more fire as vegetation dries out. 14 00:00:51,500 --> 00:00:54,670 However, if those droughts continue for a long period, 15 00:00:54,670 --> 00:00:56,080 like a megadrought, 16 00:00:56,080 --> 00:00:58,650 it can actually mean less fire. 17 00:00:58,650 --> 00:01:04,020 Because without plants, fires may run out of fuel to burn. 18 00:01:04,020 --> 00:01:06,770 But this actually isn’t a new problem. 19 00:01:06,770 --> 00:01:12,000 A recent study conducted by two NASA scientists was the first to provide evidence 20 00:01:12,000 --> 00:01:16,630 that human-generated greenhouse gas emissions were influencing drought patterns 21 00:01:16,630 --> 00:01:19,950 as long ago as the early 1900’s. 22 00:01:19,950 --> 00:01:22,170 NASA’s push to understand our past 23 00:01:22,170 --> 00:01:25,340 is in large part driven by the need to predict our future 24 00:01:25,340 --> 00:01:28,180 …to stay one step ahead of fires. 25 00:01:28,180 --> 00:01:31,870 To do this, researchers create models that not only help 26 00:01:31,870 --> 00:01:35,820 firefighters better predict where and how a fire might spread, 27 00:01:35,820 --> 00:01:40,980 but also help forest managers know when a planned burn is safe. 28 00:01:40,980 --> 00:01:46,460 NASA scientists monitor both freshwater and fires constantly, 29 00:01:46,460 --> 00:01:49,770 from space, the air and the ground, 30 00:01:49,770 --> 00:01:54,450 collecting short- and long-term data as Earth’s climate continues to change. 31 00:01:54,450 --> 00:01:59,180 Looking to the future, models are one of the best tools we 32 00:01:59,180 --> 00:02:04,140 have to prepare for changing drought and fire seasons around the world. 33 00:02:04,140 --> 00:02:11,765
