The WMO will finally confirm this in its provisional State of the Global Climate 2023 report, which will be released on November 30 – the opening day of the 28th session of the UN Climate Change conference (COP28) – in Dubai. It posted the NOAA’s findings on micro-blogging site ‘X’ late Wednesday night.
Using several international datasets, the global Met body had last week said that it was by far the warmest October on record, 0.85 degree Celsius above the 1991-2020 average, and 0.40 degree C above the previous warmest October.
“For the calendar year to date, January to October, the global mean temperature for 2023 is the highest on record, 1.43 degree C above the 1850-1900 pre-industrial average, and 0.10 degree C higher than the ten-month average for 2016 (the warmest year on record, so far),” it said.
Referring to average temperature in October which was ranked as the warmest October in the 174-year global climate record, the NOAA on Wednesday said, “Last month was also 2023’s fifth month in a row of record-warm global temperatures… The average global temperature for October was 1.34 degrees C above the 20th-century average of 14 degrees C.”
A report from WMO and the UK’s Met Office had predicted in May that there is a 98% likelihood that at least one of the next five years will be the warmest on record and a 66% chance of temporarily exceeding 1.5 degree C above the 1850-1900 average (safe warming limit under the Paris Agreement) for at least one of the five years.“This does not mean that we will permanently exceed the 1.5 degree C level specified in the Paris Agreement which refers to long-term warming over many years,” said WMO while bringing clarity on the monthly average global temperature rise.Looking regionally, the NOAA’s National Centers for Environmental Information on Wednesday underlined that Asia and South America had their warmest Octobers on record, while Africa, Europe and North America each had their second-warmest Octobers.
