Some suggestions for how to boundglobal warming conversations in pattern threads:
The earth is warming and it is unprecedented for at least a few thousand years. This I don't think is scientifically deniable. Also, the warming is being driven largely by human activity. I don't think this is scientifically deniable.
What we do from a public policy perspective is very debatable, and that is a political conversation and not for pattern threads.
Climate change is overused as an explanation for what are fairly normal shifts, for example decadal changes in things like the NAO or the EPO. These sorts of shifts would be happening regardless regardless of global warming. A particularly severe individual hurricane, for example, shouldn't be explained as being because of climate change.
Climate change can't be used to explain everything in weather. Pretending that it isn't really happening is at least as ignorant.
The impact of a warming climate on baseline climate norms and how that could affect forecasts, for example the ever-growing Hadley Cell that threatens to take over the world, is relevant to pattern discussion. The notion that hurricanes have more heat energy to work with and thus the hurricane season might be longer and feature more severe hurricanes is relevant, because the warming oceans have more heat content with which to feed hurricanes. TThis last bullet point represents the kind of content I think we should include in the pattern threads when warranted. The prior 4 bullets just provoke political polarization.
