Climate Change Triples Frequency of Atmospheric Wave Events

Climate change is making extreme summer weather more frequent and intense. A new study finds that quasi-resonant amplification (QRA) wave events — linked to heatwaves, floods, and droughts — now occur three times as often as in the 1950s, driven by rapid Arctic warming and a weakening jet stream.
