为什么世界在变暖？
-
0:03 - 0:05为什么世界在变暖？
-
0:07 - 0:10让我们暂时把地球想象成一个温室。
-
0:11 - 0:13每秒钟，大量的能量
-
0:13 - 0:15涌入我们的温室。
-
0:17 - 0:20我们的大气层，玻璃屋顶和墙壁，
-
0:20 - 0:23反射了部分能量，
-
0:23 - 0:26但大部分能量直接穿过并加热了一切。
-
0:27 - 0:30其中大部分热量被释放回太空，
-
0:30 - 0:32使我们保持稳定温暖的温度。
-
0:34 - 0:35但是后来事情变了。
-
0:36 - 0:39人类开始每天排放足够
-
0:39 - 0:41填满数十亿个温室的二氧化碳。
-
0:43 - 0:46那些温室气体是干什么的？
-
0:46 - 0:48它使我们温室的玻璃更厚。
-
0:49 - 0:51较厚的玻璃意味着
-
0:51 - 0:52热量进入空间的速度要慢得多。
-
0:52 - 0:54别忘了，来自太阳的能量
-
0:54 - 0:57仍然像以前一样快速地流入。
-
0:57 - 1:00最后的结果是，地球的温度太高，
-
1:00 - 1:04我们不喜欢，最终，我们会无法在这个星球上生活。
