00:00:05,030 --> 00:00:09,030

Around the globe, sea levels are rising.

3

00:00:09,030 --> 00:00:13,030

Greenhouse gas emissions cause our planet to warm, and

4

00:00:13,030 --> 00:00:17,030

Earth’s oceans absorb about 90% of the excess heat.

5

00:00:17,030 --> 00:00:21,030

As ice melts at the poles and high in the mountains, and the molecules

6

00:00:21,030 --> 00:00:25,030

of ocean water expand, the seas are making their way onto land.

7

00:00:25,030 --> 00:00:29,030

Since 1880, sea levels have

8

00:00:29,030 --> 00:00:33,030

risen about 8 to 9 inches. But the seas don’t rise uniformly.

9

00:00:33,030 --> 00:00:37,030

Some places are at higher risk for flooding, and

10

00:00:37,030 --> 00:00:41,030

sea levels are rising faster as time passes. Right now,

11

00:00:41,030 --> 00:00:45,030

sea level is rising about 3.3 millimeters a year, 30

12

00:00:45,030 --> 00:00:49,030

percent faster than in 1992.

13

00:00:49,030 --> 00:00:53,030

Here at NASA, we’re using satellites, like the new Sentinel-6 Michael Freilich,

14

00:00:53,030 --> 00:00:57,030

along with ships and airplanes, to study the processes

15

00:00:57,030 --> 00:01:01,030

driving sea level rise and the effects of rising waters.
