Forest Dieback Undercuts Carbon Targets

Climate‑driven tree mortality (drought, heat, pest outbreaks) is already reducing national and regional land carbon uptake; counting on historical sequestration rates is therefore a risky mitigation assumption. Policymakers must treat forest sinks as variable assets—stress‑tested, diversified (mixed species), and explicitly discounted in near‑term carbon budgets. — If forests can no longer be relied on to sequester planned amounts of CO2, nations must tighten emissions caps, revise accounting rules, and fund active adaptation (reforestation with diversity, fire/pest management) to avoid systematic target shortfalls.
