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.
