1,5 graden - TEST Grootouders voor het Klimaat TEST
Poster 1,5 graad

1,5 graden

1,5 oC 

Het woord 1,5 raakt steeds populairder. Iedereen praat over de 1,5 meter samenleving. Goed om even stil te staan bij die andere 1,5: de opwarming van de aarde met maximaal 1,5 graad, zoals afgesproken in het Akkoord van Parijs.

Hoe staat het met de opwarming?
Het jaar 2019 was het op een na warmste jaar sinds het begin van de waarnemingen: ongeveer 1 graad boven de periode 1850-1900 (het gemiddelde van alle land- en zeeoppervlakken). In Europa was het zelfs het warmste jaar ooit. Metingen over de maand maart in 2020 laten mondiaal een opwarming zien van ca 1,1 graad zien t.o.v. het gemiddelde over de maand maart in de periode 1900-2000. We zijn dus hard op weg om de 1,5 graad te passeren in de loop van deze eeuw, wellicht zelfs al over een jaar of tien.

Waarom is 1,5 graad als maximum belangrijk?
Hoe groter de opwarming, hoe ernstiger de effecten van klimaatverandering zullen zijn. Het Intergovernmental Panel on Climate Change van de Verenigde Naties (IPCC), dat de wetenschappelijke kennis samenvat, heeft op een rij gezet wat het verschil in de effecten van klimaatverandering is tussen een wereld die 2 of 1,5 graad warmer is. Kort samengevat: bij 2 graden opwarming zal alle koraal op de wereld verdwijnen, bij 1.5 graad kunnen we nog 10-30% redden; bij 2 graden elke 10 jaar een ijsvrije poolzee, bij 1,5 graad eens per 100 jaar; bij 2 graden krijgt een derde van de wereldbevolking te maken met extreme hittegolven, bij 1,5 graad blijft dat beperkt tot 10%; bij 2 graden worden 50% meer mensen geconfronteerd met watertekorten (en dus bedreigingen van voedselzekerheid) dan bij 1,5 graad, en de meest kwetsbaren zijn vooral arme mensen in ontwikkelingslanden; bij 2 graden zal het biodiversiteitsverlies 2 tot 3 keer groter zijn dan bij 1,5 graad; bij 2 graden is er een grote kans dat, over een periode van honderden tot duizenden jaren, al het ijs op Groenland en Antarctica afsmelt, met een zeespiegelstijging van tientallen meters tot gevolg, bij 1,5 graad kan dat voorkomen worden.

Dus minimaal 1,5 meter en maximaal 1,5 graad!
