Tenth consecutive monthly heat record alarms and confounds climate scientists

Another month, another global heat record that has left climate scientists scratching their heads and hoping this is an El Nino-related hangover rather than a symptom of worse-than-expected planetary health.

Global surface temperatures in March were 0.1C higher than the previous record for the month, set in 2016, and 1.68C higher than the pre-industrial average, according to data released on Tuesday by the Copernicus Climate Change Service.
