‘We Are Climbing Rapidly Out of Humankind’s Safe Zone’: New Report Warns Dire Climate Warnings Not Dire Enough

Climate Change (IPCC)—has been at the forefront of warning humanity about the processes and dangers of human-caused global warming, there has been simply too much “reticence and caution” that has led researchers to downplay the most “extreme and damaging outcomes” that lurk beneath their publicly stated findings and pronouncements.

While this has been understandable historically, given the pressure exerted upon the IPCC by political and vested interests, it is now becoming dangerously misleading with the acceleration of climate impacts globally. What were lower probability, higher-impact events are now becoming more likely.

This is a particular concern with potential climatic tipping points – passing critical thresholds which result in step changes in the climate system – such as melting polar ice sheets (and hence increasing sea levels), permafrost and other carbon stores, where the impacts of global warming are nonlinear and difficult to model with current scientific knowledge.

The extreme risks which these tipping points represent justify strong precautionary risk management. Under-reporting on these issues is irresponsible, contributing to the failure of imagination that is occurring today in our understanding of, and response to, climate change.

“Either we act with unprecedented speed,” Spratt and Dunlop conclude, “or we face a bleak future.”
