A paper was published in 2013[1] that reconstructed intermediate water temperatures (IWT) for an area of Indonesian waters around the Makassar Straight and the Flores Sea. The study includes two reconstructions, one at 500 m depth and another at 600 m to 900 m depth in an effort to show how Pacific IWT ha sbeen affected by high latitude source waters. The reconstruction somewhat predictably found that during the HTM, average IWT in this area were warmer than in 1970. Given the misuse of this paper by contrarians (see below), I think it best to quote directly from the paper so you can see precisely what this paper is actually about. The early Holocene warmth and subsequent IWT cooling in Indonesia is likely related to temperature variability in the higher-latitude source waters. To assess the mechanisms that caused these hydrographic variations, we estimate down-core salinities and densities for the 500- and 600- to 650-m depths. A temperature-salinity-density plot suggests that althoug...

GMST Anomalies (1850-2022) Data for global mean temperatures from 2022 have come in, and depending on the dataset, 2022 was either the 5th or 6th warmest year on record - some say 2015 was cooler, and some warmer. The following graph from Zeke Hausfather shows how GMST stacks up with recent years in the BEST dataset. BEST Anomaly Ranking   2022 was also the warmest La Niña year on record, despite being a stronger La Niña year than 2018 and 2021. The following is the list of anomalies, all set to deviations from the 1951-1980 mean. Where I was able to find them quickly, I included the 95% CIs for each anomaly.
