Even as Earth sets new heat records, humanity this year is pumping 330 million tons (300 million metric tons) more carbon dioxide into the air by burning fossil fuels than it did last year.
This year the world is on track to put 41.2 billion tons (37.4 billion metric tons) of the main heat-trapping gas into the atmosphere. It’s a 0.8% increase from 2023, according to Global Carbon Project, a group of scientists who track emissions. Several United Nations reports say the globe must cut emissions by 42% by 2030 to possibly limit warming to an internationally agreed-upon threshold.
