"Permafrost, wetland, wildfire and freshwater emissions could amplify climate change by up to 30%" — Mongabay · Humanitarian & Biosphere
This study quantifies how natural feedback loops—where warming itself triggers additional greenhouse gas emissions from thaw, wetland methane release, wildfires, and freshwater systems—could amplify human-caused climate change by 20–30% by 2100. Using the , the researchers estimate these 'warming-induced emissions' could add 0.2–0.4°C of extra warming, a significant but often omitted factor in climate projections.
The claim is based on a recent study (appearing as a preprint on ESS Open Archive and a PDF on ResearchGate) that uses the well-established MAGICC model. The reporting by Mongabay is secondary and does not cite a specific journal or peer-review status, so the solidity depends on whether the underlying work has been formally peer-reviewed; the preprint stage means the numbers are preliminary but grounded in established modeling methods.
Genuinely new: the Mongabay article and the underlying study were published in early October 2026, with no indication that the material is resurfaced from an earlier year.
