00:00:18,800 --> 00:00:20,455

The Arctic maximum was

2

00:00:20,455 --> 00:00:23,523

14.33 million square kilometers.

3

00:00:23,733 --> 00:00:26,793

That is the lowest maximum

4

00:00:26,793 --> 00:00:28,361

we have in our records

5

00:00:28,366 --> 00:00:30,800

that goes back to 1979.

6

00:00:33,000 --> 00:00:35,000

The Arctic maximum

7

00:00:35,000 --> 00:00:38,366

represents the end of the winter ice growth seasons.

8

00:00:38,366 --> 00:00:40,307

So the record low maximum

9

00:00:40,307 --> 00:00:42,976

that we see there this year indicates

10

00:00:42,966 --> 00:00:45,745

a warming climate where the ice is not growing

11

00:00:45,745 --> 00:00:48,281

as much as we normally would see

12

00:00:48,266 --> 00:00:50,950

and it continues the downward trend

13

00:00:50,950 --> 00:00:52,666

in the Arctic sea ice.

14

00:01:04,466 --> 00:01:06,732

The Antarctic sea ice reached

15

00:01:06,734 --> 00:01:08,266

an annual minimum extent of

16

00:01:08,266 --> 00:01:11,066

1.98 million square kilometers.

17

00:01:13,100 --> 00:01:15,000

This was the second lowest extent

18

00:01:15,000 --> 00:01:16,600

in our satellite record.

19

00:01:20,166 --> 00:01:24,500

With the Arctic sea ice reaching its lowest maximum

20

00:01:24,500 --> 00:01:28,633

and the Antarctic reaching its second-lowest minimum,

21

00:01:28,633 --> 00:01:30,900

the global sea ice extent

22

00:01:31,433 --> 00:01:34,400

reached a record low in our satellite record.

23

00:01:49,233 --> 00:01:51,266

The Arctic and Antarctic

24

00:01:51,266 --> 00:01:54,500

both being very low for their time of year

25

00:01:54,500 --> 00:01:57,083

is yet another indication of

26

00:01:57,083 --> 00:02:01,453

the long term changes in climate that we’re seeing globally,

27

00:02:01,466 --> 00:02:03,500

but are particularly

28

00:02:03,500 --> 00:02:06,266

showing up and showing up faster and earlier

29

00:02:06,266 --> 00:02:07,700

in the polar regions.
