The optimal outcome for climate change is a 1.6°C temperature increase.

The defining goal of climate policy over the past decade – limiting global warming to 1.5°C above pre-industrial levels – is now almost certainly unattainable. Limiting temperature rise to 1.6°C represents the best-case scenario for climate action, with the hope of using technologies to remove carbon dioxide from the atmosphere to return temperatures to 1.5°C later this century.

“It's impossible to achieve 1.5°C without overshooting.” Christoph Bertram A researcher at the Potsdam Climate Institute in Germany said, “Without a doubt…
