The idea is that climate change doesn’t merely increase the overall likelihood of heat waves, say, or the volume of rainfall — it also changes the flow of weather itself. By altering massive planet-scale air patterns like the jet stream

.. But when the Arctic warms up faster than the equator does — which is part of the fundamental definition of global warming, and which is already happening — the jet stream’s flow can become weakened and elongated. That’s when you can get the resultant weather extremes.
.. What the new study is saying is that in summer, in particular, this can occur... explain how enhanced high-latitude warming trends may trigger remote weather impacts,” he said.
