Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
From January to September, the global mean temperature was 1.40 °C higher than the pre-industrial average (1850–1900). [18] January 2023 was the seventh warmest on record – 0.25 °C warmer than the normal but 0.33 °C cooler than January 2020. [19] In July, the global average temperature was 17.32 °C (63.17 °F). [20]
English: Chart showing changes in global average surface temperature annually during the month of September Uploader's note: Tentatively, uploader envisions this chart as being specific to the time period ending in 2023, designed for use mainly in articles about 2023 in particular.
The global average covers 97-98% of Earth's surface, excluding only latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT, some areas with land above 1500 m altitude. The hemispheric averages are over the northern and southern hemispheres 0 to +/-85 degrees. The gridded data provide an almost global temperature map. [3]
The following is a list of weather events that occurred on Earth in the year 2023. The year saw a transition from La Niña to El Niño, with record high global average surface temperatures. The several weather events which had a significant impact were blizzards, cold waves, droughts, heat waves, wildfires, floods, tornadoes, and tropical cyclones.
HadCRUT3 is the third major revision of this dataset, combining the CRUTEM3 land surface air temperature dataset with the HadSST2 sea surface temperature dataset. First published in 2006, this initially spanned the period 1850–2005, but has since been regularly updated to 2012. Its spatial grid boxes are 5° of latitude and longitude.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
17 May: the WMO Global Annual to Decadal Climate Update projected that the chance of global near-surface temperature exceeding 1.5 °C above preindustrial levels for at least one year between 2023 and 2027 is 66%, though it is unlikely (32%) that the five-year mean will exceed 1.5 °C. [123]
