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.
