Why is 1.5 degrees such a big deal?
Por que 1,5 grau faz tanta diferença?
00:05
Because to warm our entire planet up by 1.5 degrees Celsius
Porque para aquecer nosso planeta inteiro em 1,5 °C
00:10
requires a lot of heat.
é necessário muito calor.
00:12
All this extra heat melts glaciers, which raise sea levels.
Todo esse calor extra derrete geleiras, aumentando o nível do mar.
00:16
If the ice sheets of Antarctica and Greenland melt completely,
Se as camadas de gelo da Antártida e da Groenlândia derreterem por completo,
00:19
millions of people's homes will be under water.
o lar de milhões de pessoas ficará submerso.
00:22
The extra heat also intensifies weather,
O calor excedente também intensifica o clima,
tornando lugares úmidos mais úmidos,
00:25
making wet places wetter, dry places drier
lugares secos mais secos,
00:28
and increasing the ferocity of storms.
e aumentando a intensidade de tempestades.
00:30
That 1.5-degree increase also won't be distributed evenly.
Além disso, esse 1,5 °C não será distribuído por igual.
00:34
The coldest nights in the Arctic might get 10 degrees warmer.
As noites mais frias do Ártico podem ficar 10 °C mais quentes.
00:38
The warmest days in Mumbai might get five degrees hotter.
Os dias mais quentes de Mumbai podem ficar 5 °C mais quentes.
00:41
Over the past 10,000 years, we've been lucky.
Temos tido sorte nos últimos 10 mil anos.
00:44
Earth's climate was stable and our civilizations flourished.
O clima da Terra ficou estável e a civilização floresceu.
00:48
But as our climate gets more unstable, so will our economies and our societies.
Mas à medida que nosso clima vai ficando mais instável,
o mesmo acontece com nossas economias e sociedades.
00:53
We'll all suffer,
Vamos todos sofrer,
00:55
and the vulnerable will be hit hardest,
e os vulneráveis serão os mais atingidos
00:57
unless we act now.
se não agirmos agora.
