Fig. 2: Recent global mean surface temperature anomaly evolution in HadCRUT5.
From: 2023 temperatures reflect steady global warming and internal sea surface temperature variability
a Annual means, and corrections from the SST pattern quantified via a Green’s Function. 2023 and 2016 stand out as having notably strong positive SST pattern corrections. b–d Similar, for previous strong SST correction years (1952, 1969, 1998). e Monthly correction factors, for 1950–2023 (box-and-whisker) and the selected strong correction years. The box shows the 5–95% range, and the whiskers show the max/min range. f Annual correction factors, for CMIP6 (box-and-whisker), and HadCRUT5 (1950–2023). Strong correction years are shown in colours.
