Greenland Meltwater Amplifies European Heatwaves via Jet Stream Waviness

A recent study published in New Scientist links the influx of meltwater from Greenland to intensified heatwaves across Europe. The research shows that the cooling of the North Atlantic, driven by this meltwater, is creating pronounced waviness in the jet stream. This waviness, in turn, promotes persistent high‑pressure ridging over the continent, trapping hot air and extending the duration of heat events. The findings suggest that as Greenland continues to melt, the frequency and severity of European heatwaves could rise, underscoring the interconnectedness of polar melt and mid‑latitude weather patterns.
