Hi Roger, why such an accusation? I dedicate my life to producing scientific evidence on environmental collapse & mass extinction. The paper proves how continued oil burning could be devastating, in line with what you advocate. Open to constructive criticism; read it, find flaws, let me know. Peace

Today’s policy decisions may lead to radically different food security futures. Shifting from conflict and inequality (SSP3-4) to sustainability (SSP1-2) could reduce end-of-century cumulative exposure to novel food crises by >50%.

Bottom line:
Climate change is a major driver of food crises
Socioeconomic choices determine how deadly it becomes
Today’s policies shape tomorrow’s food security.

Under pessimistic pathways, >230 million newborns could face a food crisis within their first year of life. These are not marginal differences—they are orders of magnitude apart.

The burden is highly unequal. Most future food crises are projected in Africa and Asia, with children under 5 making up the majority of first-time exposures.

When combined with population & poverty projections, model's projections depict a stark future:
➤ SSP3–4 (conflict & inequality):>1.1 billion people exposed by 2100
➤ SSP1-2(sustainability & middle-of-the-road): exposure more than halved

I developed a machine learning model using temperature & precipitation data to predict the onset of novel, severe food crises based, the model captures both direct and indirect climate effects on food security—without relying on complex socioeconomic inputs.

Conflict & inequality (SSP3-4) might expose 1.1 Billion people (>600M children, many in their first year of life) to severe food crises. My new paper shows how climate+socioeconomic pathways drive this outcome. nature.com/articles/s41...

Giant corals have survived for centuries — some sheltered in thermal refugia, others enduring repeated heatwaves. But with a looming coralgeddon, even these last giants may not be safe doi.org/10.1016/j.ge...

"would cost >AU$1.6 billion to restore just 10% of degraded coral areas globally (lowest cost/hectare & assuming all projects successful) ... using highest cost estimates, it would be >$26 trillion"
