2023 Temperatures Reflect Steady Global Warming and Internal Sea Surface Temperature Variability

B. H. Samset, M. T. Lund, et al.

In 2023, temperatures soared to unprecedented levels, raising questions about accelerating warming and aerosol cooling. Research conducted by Bjørn H. Samset, Marianne T. Lund, Jan S. Fuglestvedt, and Laura J. Wilcox reveals that these extreme temperatures are closely tied to sea surface temperature influences and internal variability, highlighting the complex interplay between natural variability and human-induced climate change.
