Why does climate change matter?

NASA

3

00:00:06,506 --> 00:00:08,541

We Asked a NASA Scientist.

4

00:00:08,541 --> 00:00:09,909

Well, it's happening.

5

00:00:09,909 --> 00:00:13,179

We look at the Earth from space

and we measure it on the ground.

6

00:00:13,179 --> 00:00:16,049

And what we see is that the planet's

climate is changing.

7

00:00:16,449 --> 00:00:20,420

The last years have been the warmest

since modern record-keeping began.

8

00:00:21,421 --> 00:00:22,622

It's serious.

9

00:00:22,622 --> 00:00:25,492

Even a little change

in temperature can have big effects.

10

00:00:25,492 --> 00:00:27,494

And we're seeing

some of those effects now.

11

00:00:27,761 --> 00:00:29,329

Sea levels are rising.

12

00:00:29,329 --> 00:00:34,534

We're seeing more extreme events like

heatwaves and heavy rainfall and wildfire.

13

00:00:34,801 --> 00:00:38,271

And we know that a lot of those effects

are going to increase with more warming.

14

00:00:38,371 --> 00:00:41,941

These changes are impacting decisions

that some people make every day,

15

00:00:41,941 --> 00:00:46,646

like a farmer thinking about what crops to grow

or a homeowner thinking about flood risk.

16

00:00:47,280 --> 00:00:48,548

But there's hope.

17

00:00:48,548 --> 00:00:51,818

There are scientists at NASA and around

the world that are researching this.

18

00:00:51,851 --> 00:00:54,754

We know more about our planet

than we have ever before,

19

00:00:54,888 --> 00:00:56,656

and we learn more every day.

20

00:00:56,656 --> 00:00:58,792

So we know why climate is changing.

21

00:00:58,892 --> 00:01:02,762

We know that it's due to increasing

greenhouse gases from human activity.

22

00:01:02,896 --> 00:01:05,732

We also have tools that can help us better understand

23

00:01:05,732 --> 00:01:08,001

and better prepare for future climate change.

24

00:01:08,414 --> 00:01:13,073

So we develop computer models that help us understand how much it might change in the future.

25

00:01:13,173 --> 00:01:16,810

And we're also developing technologies

here at NASA and around the world

26

00:01:16,810 --> 00:01:21,381

that can help us limit future warming or respond

to the warming that we're experiencing.

27

00:01:22,015 --> 00:01:23,983

So why does climate change matter?

28

00:01:23,983 --> 00:01:25,085

It's real.

29

00:01:25,085 --> 00:01:27,821

It's serious, and it's here.

30

00:01:27,821 --> 00:01:29,656

We Asked a NASA Scientist.
