A recent study from the Potsdam Institute for Climate Impact Research (PIK) predicts that by 2200, even with reduced carbon emissions, Earth could warm by 7°C (12.6°F). This would lead to food shortages due to crops struggling in the heat, flooding from rising sea levels, and frequent extreme weather events like droughts, wildfires, and storms.
The study emphasizes the urgent need for faster carbon reduction efforts, as even low-to-moderate emissions could lead to higher-than-expected warming. Methane emissions, particularly from natural sources like wetlands and landfills, also contribute significantly to warming.
The researchers used a new model to simulate climate scenarios and found that feedback loops, such as wildfires triggered by rainfall, could amplify warming. While reductions in emissions are crucial, the study warns that only very low emission scenarios can meet the Paris Agreement goal of keeping temperature rise below 2°C. The window for achieving this target is rapidly closing, and urgent action is needed to avoid catastrophic climate impacts.
