WEBVTT FILE 1 00:00:00.645 --> 00:00:03.535 Why does climate change matter? 2 00:00:05.049 --> 00:00:06.506 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. 31 00:01:29.656 --> 00:01:34.227 NASA.
