This paper argues that the IPCC has oversimplified the issue of uncertainty in its Assessment Reports, which can lead to misleading overconfidence. A concerted effort by the IPCC is needed to identify better ways of framing the climate change problem, explore and characterize uncertainty, reason about uncertainty in the context of evidence-based logical hierarchies, and eliminate bias from the ...

It may be that they are so profoundly concerned about the perils of global warming that the darkest possible picture is painted in order to secure urgent action.

Humanity is facing a set of existential challenges, including the handling parallel and interconnected crises climate change biodiversity loss. In an effort to address these international bodies like Intergovernmental Panel on Climate Change (IPCC) Science-Policy Platform Biodiversity Ecosystem Services (IPBES) have been created. These are producing series reports that compile scientific inform...

The IPCC has traditionally used words (e.g., ‘likely’) in place of numbers (‘70% chance’) to communicate risk and uncertainty information. Th...
