Summary

Description
English: Changes in global surface temperature from 1880 to 2023 (black line) relative to 1850–1900 average. Annual data from NASA here: https://climate.nasa.gov/vital-signs/global-temperature/. IPCC anomaly is 1.09 C average from 2011 to 2020 as per IPCC AR6 WG1 SPM pp5 A.1.2, so NASA data is offset to that number. Data does not go back to 1850 as datasets differ from 1850 to 1880 for NOAA, others (NASA starts in 1880, and all tend to agree from that point forward). 20-year LOWESS smooth matched to 20 year moving average as per IPCC AR6 standard for determining current warming levels. Natural influence based on CMIP6 climate model simulations of the temperature response to natural drivers only (solar and volcanic activity, green). Colored shade shows the "very likely" range of simulations. Source: IPCC AR6 WGI, Figure SPM.1b, p. SPM-7. See File:Global Temperature And Forces.svg for a version without Fahrenheit.
