Global carbon emissions from fossil fuels reached record levels again in 2023, as experts warned that the projected rate of warming had not improved over the past two years.
The world is on track to have burned more coal, oil and gas in 2023 than it did in 2022, according to a report by the Global Carbon Project, pumping 1.1% more planet-heating carbon dioxide into the atmosphere at a time when emissions must plummet to stop extreme weather from growing more violent.
The finding comes as world leaders meet in Dubai for the fraught Cop28 climate summit. In a separate report published on Tuesday, Climate Action Tracker (CAT) raised its projections slightly for future warming above the estimates it made at a conference in Glasgow two years ago.
As carbon clogs the atmosphere, trapping sunlight and baking the planet, the climate is growing more hostile to human life. The growth in CO2 emissions had slowed substantially over the past decade, the Global Carbon Project found, but the amount emitted each year had continued to rise. It projected that total CO2 emissions in 2023 would reach a record high of 40.9 gigatons.
If the world continued to emit CO2 at that rate, the international team of more than 120 scientists found, it would burn through the remaining carbon budget for a half-chance of keeping global heating to 1.5C (2.7F) above pre-industrial temperatures in just seven years. In 15 years, the scientists estimated, the budget for 1.7C would be gone too.
