Reminder from Hansen et al (April 2026) “We infer that 2026 is likely to be the warmest year in the period of instrumental data, based on a physics-based approach with identifiable assumptions. This approach may help us learn something in 2026 about the mechanisms of climate change.” https://www.columbia.edu/~jeh1/mailings/2026/2026GlobalTemperature.2026.04.30.pdf
