The Earth’s forests, soil and oceans are reaching their critical limits to naturally store carbon, as decades of climate change take their toll, according to a new analysis. The annual 10 New Insights in Climate Science report warns weaker land carbon sinks, threaten to derail emissions projections and accelerating global warming at the same time. The study highlights how forests and soils in the Northern hemisphere are reaching critical limits and are increasingly affected by wildfires and permafrost thawing. The new report is a joint initiative of Future Earth, The Earth League, and the World Climate Research Programme. “The possibility that natural sinks are weakening at the current level of warming underscores the urgent need to accelerate both emissions reductions and carbon removal,” the report states. It also adds even the oceans are soaking up less carbon dioxide, while more frequent and intense marine heatwaves take their toll.
