Our Biggest Challenge - melodysheep.mp3

[00:01.220] 【David Attenborough】: We are a flexible and innovative species
[00:05.501] and we have the capacity to adapt and modify our behavior
[00:09.760] Now, we most certainly have to do so if we're to deal with climate change.
[00:15.690] It's the biggest challenge we have yet faced.
[00:20.162] 【Bill Nye】: The same thing that keeps the Earth warm
[00:23.495] CO2
[00:25.901] May make the Earth too warm
[00:29.521] It holds in heat
[00:31.818] Methane, Chloroflourocarbons, water vapor and
[00:34.553] Carbon dioxide - they all trap heat
[00:37.079] Methane, Chloroflourocarbons, water vapor and
[00:39.456] Carbon dioxide - they all trap heat
[00:41.694] 【Isaac Asimov】: It is important that the world get together
[00:45.878] To face the problems which attack us as a unit
[00:52.597] 【Richard Alley】: The evidence is clear
[00:55.614] 【Nye】: The globe is getting too warm
[00:57.912] 【Alley】: We can avoid climate catastrophes
[01:00.868] We can do this
[01:02.539] 【Nye】: We can change the world
[01:04.465] 【Alley】: Science offers us answers
[01:07.373] To these huge challenges
[01:09.146] 【Nye】: It's one global ecosystem
[01:11.498] 【Alley】: We can do this
[01:13.402] 【Nye】: We can change the world
[01:19.387] Every single thing every one of us does
[01:24.557] Affects everybody all over the world
[01:27.561] It's one global ecosystem
[01:30.635] Warm, wet, cold or dry
[01:32.573] Climates all start in the sky
[01:35.710] Warm, wet, cold or dry
[01:38.117] Climates all start in the sky
[01:40.768] When the CO2 is high, the temperature is high
[01:43.890] Moving together in lock step
[01:46.071] When the CO2 is low, the temperature is low
[01:48.893] Moving together
[01:51.368] 【Isaac Asimov】: It is important that the world get together
[01:55.921] To face the problems which attack us as a unit
[02:01.605] 【Richard Alley】: The evidence is clear
[02:04.287] 【Nye】: The globe is getting too warm
[02:07.235] 【Alley】: We can avoid climate catastrophes
[02:09.613] We can do this
[02:11.444] 【Nye】: We can change the world
[02:13.927] 【Alley】: Science offers us answers
[02:16.990] To these huge challenges
[02:18.421] 【Nye】: It's one global ecosystem
[02:21.125] 【Alley】: We can do this
[02:22.773] 【Nye】: We can change the world
[02:27.032] 【Richard Alley】: Our use of fossil fuels for energy is pushing us towards a climate
[02:30.582] unlike any seen in the history of civilization
[02:33.468] Adding carbon dioxide to the atmosphere
[02:36.739] Warms things up
[02:39.602] The rise in CO2
[02:41.776] Comes from burning fossil fuels
[02:44.621] When you burn them, add oxygen
[02:47.545] That makes CO2 that goes in the air
[02:50.167] We're reversing the process by which they formed
[02:54.997] 【Asimov】: We're talking about something
[02:58.118] That affects the entire Earth
[03:00.427] Problems that transcend nations.
[03:05.559] 【Isaac Asimov】: It is important that the world get together
[03:10.071] To face the problems which attack us as a unit

[03:21.601] 【Alley】: We can avoid climate catastrophes
[03:24.192] We can do this
[03:26.359] 【Nye】: We can change the world
[03:28.515] 【Alley】: Science offers us answers
[03:31.532] To these huge challenges
