evidence: Average global temperatures hit nearly 1.3 Â°C above preindustrial levels in 2022 and are expected to reach even higher this year. At current trends, the world could surpass 1.5 Â°C of warming within a decade, if not sooner. Assuming moderate emissions into the future, climate models assessed by the Intergovernmental Panel on Climate Change project a range of warming (orange) by 2100 that is well above 2 Â°C. [...] âWe could effectively hit 1.5 degrees of warming each year for a whole decade before the long-term average passes that mark,â says Zeke Hausfather, a climate scientist at Berkeley Earth, a non-profit organization in California that tracks global temperatures. It wonât stop there. Models that use projected carbon emissions estimate that global temperatures will increase by 2.4â2.6âÂ°C above pre-industrial values by 2100, on the basis of current pledges that countries have made as part of the Paris agreement.
