Why is 1.5 degrees such a big deal?
なぜ1.5℃がそれほど重大なのでしょう?
00:05
Because to warm our entire planet up by 1.5 degrees Celsius
地球全体の気温を1.5℃上昇させる熱は
00:10
requires a lot of heat.
莫大な量であるからです
00:12
All this extra heat melts glaciers, which raise sea levels.
この過剰な熱は氷河を解かし 海面を上昇させます
00:16
If the ice sheets of Antarctica and Greenland melt completely,
南極大陸とグリーンランドの氷床が 全て解けてしまえば
00:19
millions of people's homes will be under water.
何百万人もの家が 水面下に沈んでしまうのです
00:22
The extra heat also intensifies weather,
さらには過剰な熱が 極端な天候を生じ
00:25
making wet places wetter, dry places drier
湿潤地の降水量は増え 乾燥地はより乾燥します
00:28
and increasing the ferocity of storms.
そして嵐はさらに激しさを増します
00:30
That 1.5-degree increase also won't be distributed evenly.
この1.5℃の気温上昇の影響は 不均等に現れます
00:34
The coldest nights in the Arctic might get 10 degrees warmer.
北極地方では最も寒い日の 夜の気温が10℃高くなり
00:38
The warmest days in Mumbai might get five degrees hotter.
ムンバイでは最も暑い日の日中の気温が 5℃高くなるかもしれません
00:41
Over the past 10,000 years, we've been lucky.
過去1万年間 我々はラッキーだったのです
00:44
Earth's climate was stable and our civilizations flourished.
地球の気候は安定しており 文明が栄えることができました
00:48
But as our climate gets more unstable, so will our economies and our societies.
しかし気候がより不安定になれば 経済も社会も安定を失います
00:53
We'll all suffer,
今すぐ行動を起こさなければ
00:55
and the vulnerable will be hit hardest,
誰もが被害を被りますが 一番ひどい目に遭うのは弱者です
00:57
unless we act now.
