Can Arctic warming influence UK extreme weather?

We explore a possible relation between the recent Arctic amplification of global warming and changes in North Atlantic jet stream circulation and UK extreme weather conditions over the last decade. Such a link is supported by some tantalising clues from recent North Atlantic atmospheric circulation changes in summer and winter, but due to multiple factors affecting jet stream variability, we need extended records over at least a further decade to more reliably attribute these changes to global warming.
