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 ...
The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 is expected to be 1.4 °C above it. [5]

English: Charts comparing percentages of Earth's surface reaching record temperatures since 1951, comparing records for January, April, July and October, from NOAA data. Source of data for series of charts titled "mm Month - Percent of global area at temperature records - Global warming - NOAA.svg":
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 year 2023 had already been confirmed as the hottest on record, but new data shows an alarming rise in heating towards the Paris Agreement limit. World is dangerously close to a global warming ...
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.
2023 surface air temperatures breached the 1.5 °C threshold for a record number of days. The world breached the Paris Agreement 1.5 °C warming mark for a record number of days. [17] From January to September, the global mean temperature was 1.40 °C higher than the pre-industrial average (1850–1900). [18]
