Global carbon dioxide emissions, including those from burning fossil fuels, are set to hit a record high this year, pulling the world further off course from averting more destructive climate extremes, scientists said on Wednesday. The Global Carbon Budget report, published during the UN’s COP29 climate summit in Azerbaijan, said global CO2 emissions are set to total 41.6-billion metric tons in 2024, up from 40.6-billion tons last year.
