The Stratospheric Metronome of Global Weather Is Fading Under Global Warming

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “The disappearing quasi-biennial oscillation under sustained global warming” by Luo et al. (2026). Luo et al. (2026) examines the potential permanent disappearance of the Quasi-Biennial Oscillation (QBO), a major atmospheric cycle, due to prolonged global warming. Using CMIP6 climate models and high-emission scenarios, the study finds that... Continue Reading →
