Why is 1.5 degrees such a big deal?
Pourquoi 1,5 degré est-il décisif ?
00:05
Because to warm our entire planet up by 1.5 degrees Celsius
Parce que réchauffer toute la planète de 1,5 degré celsius
nécessite beaucoup de chaleur.
00:10
requires a lot of heat.
00:12
All this extra heat melts glaciers, which raise sea levels.
Cette chaleur supplémentaire fait fondre les glaciers
et monter le niveau de la mer.
00:16
If the ice sheets of Antarctica and Greenland melt completely,
Si les calottes glaciaires de l'Antarctique et du Groenland
00:19
millions of people's homes will be under water.
fondaient complètement,
des millions de maisons seraient inondées.
00:22
The extra heat also intensifies weather,
La chaleur supplémentaire accentue les climats extrêmes :
00:25
making wet places wetter, dry places drier
les zones humides sont plus humides, les zones sèches, plus sèches,
00:28
and increasing the ferocity of storms.
et la férocité des tempêtes s'amplifie.
00:30
That 1.5-degree increase also won't be distributed evenly.
De plus, cette augmentation de 1,5 degré ne sera pas répartie uniformément.
00:34
The coldest nights in the Arctic might get 10 degrees warmer.
Les nuits les plus froides de l'Arctique pourraient se réchauffer de 10 degrés
00:38
The warmest days in Mumbai might get five degrees hotter.
et les jours les plus chauds à Mumbai, de 5 degrés.
00:41
Over the past 10,000 years, we've been lucky.
Ces 10 000 dernières années, nous avons eu de la chance.
00:44
Earth's climate was stable and our civilizations flourished.
Le climat de la Terre était stable
et nos civilisations ont prospéré.
00:48
But as our climate gets more unstable, so will our economies and our societies.
Mais l'instabilité croissance du climat
va rendre nos économies et nos sociétés de plus en plus instables.
00:53
We'll all suffer,
Nous allons tous souffrir
00:55
and the vulnerable will be hit hardest,
et les plus vulnérables seront les plus affectés
00:57
unless we act now.
à moins que nous agissions maintenant.
