1
00:00:05,638 --> 00:00:06,690
Well, according to NASA's

2
00:00:06,690 --> 00:00:10,410
records, 2022 is tied
for the fifth warmest on record.

3
00:00:10,643 --> 00:00:11,428
And collectively,

4
00:00:11,428 --> 00:00:14,781
the last nine years have been the warmest
since modern recordkeeping began.

5
00:00:15,198 --> 00:00:18,651
Temperatures
in 2022 were about 1.1 degrees Celsius

6
00:00:18,651 --> 00:00:22,489
or about 2 degrees Fahrenheit
above the late 19th century average.

7
00:00:22,706 --> 00:00:25,975
And while that may sound
like a small number, just small changes

8
00:00:25,975 --> 00:00:29,162
in temperature
can have big impacts around the world.

9
00:00:34,250 --> 00:00:36,169
So what we see with with climate change,

10
00:00:36,169 --> 00:00:38,004
with the temperatures
that we're already experiencing,

11
00:00:38,004 --> 00:00:42,175
this 1.1 degrees Celsius or 2 degrees
Fahrenheit, we're already seeing impacts.

12
00:00:42,175 --> 00:00:45,361
So we see declines in the extent
and mass of Arctic sea ice.

13
00:00:45,595 --> 00:00:48,748
We see increases in sea level
and we see more extreme events

14
00:00:48,748 --> 00:00:52,802
like heatwaves and wildfires,
more changes in precipitation patterns

15
00:00:52,802 --> 00:00:56,823
that lead to more droughts and floods
and heavy precipitation events.

16
00:00:57,057 --> 00:00:58,591
So we're seeing these these changes

17
00:00:58,591 --> 00:01:02,846
in our Earth system
already driven by climate change.

18
00:01:06,683 --> 00:01:06,950
So we

19
00:01:06,950 --> 00:01:10,019
use the vantage point of space
to observe the Earth from space.

20
00:01:10,019 --> 00:01:12,572
We can see all of the Earth
and we can measure different things.

21
00:01:12,772 --> 00:01:15,692
So each of our satellites
is designed to measure something different

22
00:01:15,692 --> 00:01:16,609
about the planet.

23
00:01:16,609 --> 00:01:20,513
And so what we can see are things like
vegetation, changes in the massive ice

24
00:01:20,513 --> 00:01:24,901
sheets, clouds and precipitation, carbon
dioxide and much more.

25
00:01:24,984 --> 00:01:27,003
And we've been observing the planet
for decades.

26
00:01:27,003 --> 00:01:27,570
So we can see

27
00:01:27,570 --> 00:01:31,291
not just the state of the Earth today,
but also how it's changed over time.

28
00:01:31,608 --> 00:01:35,161
The most recent satellite
we launched, SWOT, which NASA launched

29
00:01:35,161 --> 00:01:38,832
in December, shows us surface
water and ocean topography.

30
00:01:38,848 --> 00:01:40,100
So it can, it's going to be able
to tell us

31
00:01:40,100 --> 00:01:42,318
how much water
is running through rivers and lakes

32
00:01:42,318 --> 00:01:44,938
and also give us more information
about ocean circulation.

33
00:01:45,121 --> 00:01:48,324
And oceans play a really important role
in climate change in that they absorb

34
00:01:48,324 --> 00:01:51,528
a lot of heat and carbon
and so will give us more information

35
00:01:51,528 --> 00:01:55,348
about their potential
to do so in the future.

36
00:01:59,219 --> 00:02:02,188
So what we're seeing is increases
in temperatures have continued.

37
00:02:02,188 --> 00:02:05,542
So over the last nine years, the warmest
since modern recordkeeping began.

38
00:02:05,875 --> 00:02:06,993
We know that the changes

39
00:02:06,993 --> 00:02:10,680
that we've experienced so far are driven
by greenhouse gases from human activity.

40
00:02:10,947 --> 00:02:14,701
And what science tells us is that future
warming will depend on future emissions.

41
00:02:14,901 --> 00:02:18,271
And if temperatures continue to rise,
we'll see more of these impacts

42
00:02:18,271 --> 00:02:20,306
and extreme events
that we're experiencing today.

43
00:02:20,306 --> 00:02:24,527
So more heatwaves, more wildfires,
more droughts and heavy precipitation

44
00:02:24,527 --> 00:02:28,047
events in the future with more warming.

45
00:02:32,268 --> 00:02:36,322
So 2022 is what scientists
and meteorologists call a La Niña year.

46
00:02:36,573 --> 00:02:39,209
And in general, La
Niña years are cooler than average.

47
00:02:39,442 --> 00:02:42,662
But 2022 is still tied
for the fifth warmest

48
00:02:42,662 --> 00:02:45,899
and among the nine warmest years on record
because of climate change.

49
00:02:46,316 --> 00:02:49,219
So we are seeing increases in temperature
now that

50
00:02:49,219 --> 00:02:52,338
continue into the future.

51
00:02:56,125 --> 00:02:57,577
