For years, Canadians were told that catastrophic climate scenarios justified virtually any policy imposed in the name of emissions reductions. In agriculture and food, this translated into mounting costs across the supply chain, escalating industrial carbon pricing, and a policy environment increasingly disconnected from affordability and competitiveness.

Now, quietly, the scientific conversation is evolving.

CHARLEBOIS: Canada’s costly climate gamble on food needs to end Back to video

A recent paper published in Geoscientific Model Development, tied directly to the next generation of UN-backed climate modeling for the IPCC’s upcoming assessment cycle, suggests that some of the most extreme warming scenarios used for years are no longer considered plausible. The infamous SSP5-8.5 pathway, often portrayed publicly as a “business-as-usual” future, assumed an explosion in coal consumption, extraordinarily high fossil fuel dependence, and emissions trajectories that increasingly diverged from economic and technological realities.

In plain English: some of the world’s leading climate scientists are now acknowledging that humanity is unlikely to follow the catastrophic path that dominated climate communication for much of the last decade.

Yet Canadian policy, especially in agri-food, still behaves as though we are one harvest away from Mad Max.
