If all signatory countries to the Paris Climate Agreement achieve their voluntary climate targets for 2030 (Nationally Determined Contributions, NDCs), the planet would warm by 2.6 degrees by 2100. This is the result of a new calculation by the Climate Action Tracker (CAT), which was published on Thursday at COP29. Last year, the CAT had still reached 2.5 degrees of warming, and 2.4 degrees the year before.
