evidence: Temperatures rising ‘more exponentially’ Several months ago, there was a projection among the scientific community that warming would hit around 1.3 degrees in 2023, said Liz Bentley, chief executive of the UK’s Royal Meteorological Society. That prediction has been "annihilated," she said, as temperature records fell on the regional, national and international levels around the world, including daily and monthly records. [...] "If you look at climate projections, when we expect to see temperature changes of close to 1.5 degrees Celsius, indeed it has come sooner than many would have expected," Bentley told CNN. "We’ve definitely seen an acceleration towards that, rather than it being a kind of linear progression. It feels like it’s rising much more exponentially."
