The argument

About this talk

Presented at the Darebin Climate Emergency Conference in Melbourne and published by the City of Darebin.

David Spratt argues that climate change is already dangerous, and that the warming projected in the wake of the 2015 Paris Agreement poses a threat to human civilisation unless the pace and scale of action increases radically.

The presentation reviews recent observations, projected warming and impacts on key features of the climate system, and examines how the understatement of climate risk has become embedded in the way scientific research is communicated and translated into policy. It closes by setting out parameters for returning to a safe climate.

The signal

Key takeaways

01

Credit where it is due

This talk was recorded and published by the City of Darebin. MEER links to the official recording rather than reposting it.

02

The tail of the risk distribution matters

For an existential threat, planning around the mid-range projection leaves the most consequential outcomes unaddressed.

03

Scientific reticence shapes policy

Cautious framing in research communication travels into policymaking, where it reads as reassurance rather than uncertainty.

04

Post-Paris warming is not safe

The pathways implied by current pledges remain far from the conditions in which human societies developed.

05

A safe climate is a definable goal

Spratt argues for stating the target in physical terms and working back to the pace and scale of action it requires.
