Forecast puts possible global warming by 2100 at up to 5.7°C
Global temperatures could rise by as much as 5.7°C by the end of this century, according to a forecast discussed in a climate science explainer.
The explainer is by Masahiro Watanabe, a professor at the University of Tokyo’s Atmosphere and Ocean Research Institute.
It focuses on how much hotter Earth may become by 2100.
The 5.7°C figure is presented as a possible maximum, not a certain outcome.
The difference matters because it shows that forecasts describe a range of possible future warming.
The available information does not explain what assumptions produce that maximum or give details of the other forecasts.
It does not say what action or next step is planned.
