Why is 1.5 degrees such a big deal?
Hvorfor har 1,5 grader så mye å si?
00:05
Because to warm our entire planet up by 1.5 degrees Celsius
Fordi å varme opp hele planeten med 1,5 grader
00:10
requires a lot of heat.
krever mye varme.
00:12
All this extra heat melts glaciers, which raise sea levels.
All den ekstra varmen smelter isbreer, som hever havnivået.
00:16
If the ice sheets of Antarctica and Greenland melt completely,
Hvis isen på Antarktis og Grønland smelter helt,
00:19
millions of people's homes will be under water.
vil millioner av folks hjem være under vann.
00:22
The extra heat also intensifies weather,
Den ekstra varmen gjør også været mer intenst,
00:25
making wet places wetter, dry places drier
så våte steder blir våtere, tørre steder blir tørrere
00:28
and increasing the ferocity of storms.
og stormer øker i voldsomhet.
00:30
That 1.5-degree increase also won't be distributed evenly.
Økningen på halvannen grad vil heller ikke være spredt jevnt.
00:34
The coldest nights in the Arctic might get 10 degrees warmer.
De kaldeste nettene i Arktis kan bli ti grader varmere.
00:38
The warmest days in Mumbai might get five degrees hotter.
De varmeste dagene i Mumbai kan bli fem grader hetere.
00:41
Over the past 10,000 years, we've been lucky.
I løpet av de siste 10 000 årene har vi vært heldige.
00:44
Earth's climate was stable and our civilizations flourished.
Jordas klima var stabilt og våre sivilisasjoner blomstret.
00:48
But as our climate gets more unstable, so will our economies and our societies.
Men når klimaet blir mer ustabilt, blir også økonomien og samfunnet det.
00:53
We'll all suffer,
Vi vil alle lide,
00:55
and the vulnerable will be hit hardest,
og de sårbare vil bli rammet hardest
00:57
unless we act now.
om vi ikke handler nå.
