A single cold snap is no more evidence for climate change than it is against global warming. The earth is huge, climate is chaotic and oscillatory with large variance, you need many data points over, at a minimum, decades (though centuries or millennia may be more appropriate) to determine with certainty that the climate is changing.
- GVIrish 6y agoThis cold snap is due to the polar vortex destabilizing and pushing arctic air down South. Normally the polar vortex stays stable and that arctic air oscillates at higher latitudes. But with warmer temperatures in the higher latitudes that stability has been disrupted and a large part of the vortex air has been pushed South. The arctic is warming much faster that the rest of the planet, so these events will probably become much more common. Other sorts of extreme weather events are also going to become more common with climate change Some explainers on the polar vortex: https://www.carbonbrief.org/qa-how-is-arctic-warming-linked-to-polar-vortext-other-extreme-weather https://www.carbonbrief.org/qa-how-is-arctic-warming-linked-...
