Overlooked Climate Feedback Loops Could Make Global Warming 30% Worse

A new study finds that climate feedback loops — where warming itself triggers additional greenhouse gas emissions — could make global warming roughly 30% worse than current projections suggest. If accurate, that means existing carbon budgets and emissions targets underestimate how fast the planet is heating, with implications for how aggressively governments and industry must cut emissions.

• Warming-induced greenhouse gas emissions are amplifying temperature rise beyond what models account for.
• The study estimates the overlooked feedback loops could increase global warming by about 30%.
• Climate targets and carbon budgets built on current projections may be too lenient.
