In the past US science agencies have cited IPCC findings and predictions, which link increasing average global temperatures with climate change, resulting in extreme weather events increasing in frequency and magnitude. Your explanation of the basic thermodynamic concept of warmer atmospheres holding more water vapor, which you also state "set up" these extreme snow and rainfall events in the "shoulder months", seems to align with the findings in the IPCC reports that attribute global warming to climate change which generates more severe weather events like these. Since your explanation seems to validate the findings of the IPCC are your "attribution scientists" still citing the IPCC and many other well cited global climate science research institutions? If not what resources are you citing? And is there another explanation for the IPCC's prediction of the increasing frequency and magnitude in extreme weather events like storms, floods, hurricanes, tornados and droughts that we are beginning to witness?
