Why is 1.5 degrees such a big deal?
Per què 1,5 graus resulten tan importants?
00:05
Because to warm our entire planet up by 1.5 degrees Celsius
Perquè escalfar tot el planeta 1,5 graus centígrads
00:10
requires a lot of heat.
requereix molta calor.
00:12
All this extra heat melts glaciers, which raise sea levels.
Tota aquesta calor extra fon les glaceres, i això eleva el nivell del mar.
00:16
If the ice sheets of Antarctica and Greenland melt completely,
Si les capes de gel de l’Antàrtida i Groenlàndia es fonen del tot,
00:19
millions of people's homes will be under water.
l'aigua cobrirà milions de llars.
00:22
The extra heat also intensifies weather,
La calor addicional també fa el temps més extrem,
00:25
making wet places wetter, dry places drier
fa els llocs humits més humits, i els secs més secs,
00:28
and increasing the ferocity of storms.
fa que augmenti la ferocitat de les tempestes.
00:30
That 1.5-degree increase also won't be distributed evenly.
Aquest augment de 1,5 graus tampoc no es distribuirà de manera uniforme.
00:34
The coldest nights in the Arctic might get 10 degrees warmer.
Les nits més fredes de l’Àrtic poden escalfar-se deu graus.
00:38
The warmest days in Mumbai might get five degrees hotter.
Els dies més càlids a Bombai poden augmentar cinc graus.
00:41
Over the past 10,000 years, we've been lucky.
Durant els darrers 10 000 anys, hem tingut sort.
00:44
Earth's climate was stable and our civilizations flourished.
El clima de la Terra era estable i les nostres civilitzacions van prosperar.
00:48
But as our climate gets more unstable, so will our economies and our societies.
Però com més inestable es torna el clima més ho faran l'economia i la societat.
00:53
We'll all suffer,
Tots patirem,
00:55
and the vulnerable will be hit hardest,
i els més vulnerables seran els més afectats,
00:57
unless we act now.
tret que actuem ara.
