For each occasions, you may blame the jet stream – the fast-moving air currents that stream west to east across the globe. In October 2024, the polar jet had buckled, trapping a high-pressure anticyclone system over the UK and a low-pressure system over Spain. That isn’t unprecedented: the jet stream buckles sometimes. However even the informal observer might need seen that climate occasions appear to be lingering longer throughout the northern hemisphere, from Europe to North America. Now, local weather scientists are scrambling to determine whether or not international warming is making the jet stream extra erratic, as some have predicted.
We urgently want solutions. If we don’t get a transparent image of how the jet stream is altering, and what meaning for our climate, we might be dramatically underestimating the acute occasions coming our means. “We really need to keep pushing for an understanding of these extremes,”…
