The coming Super El Niño could push a hotter world towards food crisis

Spoiler alert: Read this before repeating the recent claims. (A good, long write up investigating the thin sources behind the claims.)

David Spratt @djspratt.bsky.social · 10/08/2026

The claim that four billion people could die in a 3°C warmer world has become a powerful climate narrative. But what does the science actually support, and where does evidence end and speculation begin? www.climatecodered.org/2026/08/coul...

Could Four Billion People Die at 3°C?

Any sane foreign policy would put climate risks, not China, at centre stage. Australia’s security policy settings are focused on geopolitical rivalry, while far greater systemic risks – especially climate disruption – receive little strategic attention. johnmenadue.com/post/2026/04...

As we collectively work to get political systems to understand the need for urgent #climate interventions, is an assumption that such processes are fit for purpose? Are climate policy-makers capable of understanding the risks and acting rationally on that basis? johnmenadue.com/post/2026/04...

Has climate policy-making gone completely off the rails?

Planning to “adapt” to 3°C of warming risks normalising catastrophic outcomes - and avoiding the urgent task of deep, immediate decarbonisation.

Great @scitalkofficial.bsky.social episode with @djspratt.bsky.social on what's wrong with our climate policy makers. David suggests some just don't (want to) get the problem. And I totally agree.

Will Australia's new National Climate Risk Assessment – more omission than commission? johnmenadue.com/post/2025/08... Will it describe full spectrum of climate risks Australians will face, or be marred by a poor approach to risk analysis, bureaucratic incompetence and a limited vision?
