Changes to temperature and rainfall could shave half a year from the average life expectancy, research found, with women and people in developing countries hit disproportionately.
Strictly, the WMO found that the annual average global temperature was 1.45 degrees Celsius higher than pre-industrial levels. They consolidated six leading datasets used for monitoring global temperatures, all of which ranked 2023 as the warmest year on record. The datasets included those developed and maintained by space and meteorological agencies in the US - NASA and NOAA - along with those in the UK, Europe and Japan, before arriving at their conclusions regarding the year 2023.
Analysis follows that of the EU s climate change service Copernicus earlier this week which showed each month from June to December being the hottest corresponding month on record.
