The WMO provisional State of the Global Climate report confirms that 2023 is set to be the warmest year on record. Data until the end of October shows that the year was about 1.40 degrees Celsius (with a margin of uncertainty of ±0.12°C )above the pre-industrial 1850-1900 baseline. The difference between 2023 and 2016 and 2020 - which were previously ranked as the warmest years - is such that the final two months are very unlikely to affect the ranking.
