Scientists have identified exactly how it is that climate change may increase the likelihood of extreme weather events around the globe. You can read the full details here, but the gist of it is that there are normally what is, in essence, atmospheric ‘waves’ oscillating between the artic and tropic regions, which help mix things up. During recent extreme weather events, those waves were more or less frozen in place, something which climate change may make more likely as the planet is not heating uniformly (the poles heat more than the tropical areas, hence there’s less temperature different between them to drive the oscillations).
