Study: Remaining CO2 budget for 1.5 degrees is almost used up

The CO2 budget still available to the world if global warming is to be limited to 1.5 degrees with a 50 percent probability has probably halved in the past three years. This is the conclusion of a recent study by an international research network. It was recently published in Earth System Science Data and presented at the UN Climate Change Conference SB 58 in Bonn.
