heat extremes could become an «emerging feature» of a warmer planet, according to a new study. The new research that reviewed the weather and climate of 2023 also said that many of the extreme events experienced last year are consistent with predictions previously made about a warmer world. Putting the events of the warmest year on record in perspective, researchers said that in a warmer future, more events involving record-breaking hot temperatures occurring earlier in the year, and cyclones exacerbating rainfall extremes are in order.
Change in seasonality of extreme events too is another trend the researchers observed.
«We are seeing extremes appearing in seasons in which they are usually less likely. Heatwaves, for example, appeared in spring 2023 in southwestern Europe, Brazil, Morocco and South Africa,» Robin Clark of the Met Office in the UK, a co-author of the study published in the journal Advances in Atmospheric Science, said.
Further, multiple regions across the world simultaneously experiencing heat extremes could become an «emerging feature» of a warmer planet, the researchers said.
Many regions of North America, southern Europe, northern Africa, and Asia together experienced record-breaking hot extremes in the month of July last year.
The team also found that intense cyclones exacerbated rainfall extremes such as the Libya flooding in September and the North China flooding in July 2023.
They said that an increased occurrences of such events too are in line with projections about the future under
