.. the real risk of geoengineering is not some Hollywood-style catastrophe, but complacency. A cheap way to delay the effects of warming risks undermining the need to rapidly reduce emissions, and going down that path would risk locking our children into a dependency where even stopping the process becomes too expensive to contemplate...

SO2 declines have contributed ~25% of recent warming and driven recent acceleration. The impact of additional SO2 emissions on cloud formation diminishes as emissions increase, meaning that reductions in SO2 over areas with low background sulphate concentrations, such as the ocean, could result in a proportionately larger warming effect than in highly polluted areas, such as south Asia.

Carbon Brief provides an updated analysis of when the world will likely exceed the Paris 1.5C limit

Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.

Alors que le réchauffement de la planète est en passe de dépasser le seuil de 1,5 °C, éliminer le carbone de l’atmosphère tout en réduisant les émissions s’avère crucial, explique, dans une tribune au « Monde », le spécialiste du climat Zeke Hausfather.

Bomen planten is essentieel in de strijd tegen de klimaatverandering, maar CO2 uit de lucht halen en permanent opslaan in de ondergrond is minstens even belangrijk. De ene methode vervangt de andere niet, want ze hebben een totaal ander doel, schrijven internationale klimaat- en natuurexperten.

Les médias affirment souvent que le monde est confronté à un “réchauffement déjà acté pour l’avenir” en raison des émissions passées, ce qui signifie que des températures plus élevées sont “verrouillées”, “sur les rails” ou “inévitables”, quels que soient les choix de société pris aujourd’hui.

The best available evidence shows that, on the contrary, warming is likely to more or less stop once carbon dioxide (CO2) emissions reach zero, meaning humans have the power to choose their climate future.
