At Current (Increasing) Emissions Rates, 1.5C Threshold Of Catastrophic Warming Will Be Surpassed By 2030

Global carbon emissions from fossil fuels are projected to rise to an all-time high this year, with increases expected to accelerate in the United States and European Union but slow in China and India, according to a report published Wednesday evening. At this rate, the authors said, it will take the world four years to pass the 1.5-degree threshold that experts have agreed would constitute catastrophic warming.

The latest Global Carbon Budget report, which measures annually how much carbon is emitted as well has how much the planet absorbs through the land and ocean, paints a bittersweet portrait of planetary warming, the authors said. It underscores how even as parts of the world pivot to renewable energy and decrease their emission rates, the planet is on track to keep heating up. Fossil fuel emissions are projected to rise by 1.1 percent, amounting to 38.1 billion metric tons of fossil carbon dioxide emissions in one year, the report found.

“These findings are in line with recent years, showing a regional shift in fossil fuel emissions but with an overall continuing increase,” said Anna Michalak, founding director of the Carnegie Climate and Resilience Hub at the Carnegie Institution for Science, who studies the cycling and emissions of greenhouse gases.

Also evident in the carbon budget report is how the world’s natural barriers to global warming continue to weaken. Each year roughly half of the greenhouse gases that people emit is absorbed by the earth and the sea. But the planet’s ability to sink some of that carbon appears to be weakening as climate change worsens, said Pierre Friedlingstein, the report’s lead author and a professor at the University of Exeter. Friedlingstein develops global models to try to understand the interaction between climate systems, climate change and the global carbon cycle. “The more warming we have in the future, the less the system is efficient in removing Co2,” he said.
