Warmists propose that colder Northern Hemisphere winters since 1988 are due to global warming

The Hockey Schtick
"So what's going on here?
Cohen et al. say that "whether the recent colder winters are a consequence of internal variability or a response to changes in boundary forcings resulting from climate change remains an open question." But like most scientists who love to resolve dilemmas, they go on to propose their answer to the puzzle, suggesting that "summer and autumn warming trends are concurrent with increases in high-latitude moisture and an increase in Eurasian snow cover, which dynamically induces large-scale wintertime cooling."
