Why is 1.5 degrees such a big deal?
Porque é que 1,5 grau é um problema tão grande?
Because to warm our entire planet up by 1.5 degrees Celsius
Porque, para aquecer o planeta inteiro em 1,5 grau Celsius,
requires a lot of heat.
é preciso imenso calor.
All this extra heat melts glaciers, which raise sea levels.
Todo este calor extra derreterá os glaciares,
o que fará subir o nível da água do mar.
If the ice sheets of Antarctica and Greenland melt completely,
Se os mantos de gelo da Antártida e da Gronelândia derreterem na totalidade,
millions of people's homes will be under water.
as casas de milhões de pessoas ficarão debaixo de água.
The extra heat also intensifies weather,
O aquecimento extra também intensifica o clima,
making wet places wetter, dry places drier
tornando mais húmidos os locais húmidos, mais secos os locais secos,
and increasing the ferocity of storms.
e aumentando a ferocidade das tempestades.
That 1.5-degree increase also won't be distributed evenly.
Este aumento de 1,5 grau não será distribuído uniformemente.
The coldest nights in the Arctic might get 10 degrees warmer.
As noites mais frias do Ártico poderão ficar 10 graus mais quentes.
The warmest days in Mumbai might get five degrees hotter.
Os dias mais quentes em Bombaim poderão ficar cinco graus mais quentes.
Over the past 10,000 years, we've been lucky.
Ao longo dos últimos 10 000 anos, temos tido sorte.
Earth's climate was stable and our civilizations flourished.
O clima da Terra manteve-se estável e as nossas civilizações prosperaram.
But as our climate gets more unstable, so will our economies and our societies.
Mas, à medida que o clima fica mais instável,
o mesmo acontecerá com as nossas economias e sociedades.
We'll all suffer,
Todos sofreremos,
and the vulnerable will be hit hardest,
e os mais vulneráveis serão os mais afetados,
unless we act now.
a menos que atuemos já.
