World Has Nine Years to Avert Catastrophic Warming, Study Shows

Nations will likely burn through their remaining carbon budget in less than a decade if they do not significantly reduce greenhouse gas pollution, a new study shows, causing the world to blow past a critical warming threshold and triggering catastrophic climate impacts. To have a chance of keeping global temperature rise within 1.5 degrees Celsius, humanity can release no more than 380 billion tons of carbon dioxide equivalent over the coming decades — an amount equal to about nine years of current emissions, the report says.
