Friends who relocated in southern Utah from LA told me temperatures have been down to minus 20 to minus 30 for the past several nights, and people who were born and raised there say it’s never ever been that cold.
I was in minus 30 weather once in Vermont, plus there was a strong wind, which makes it life threatening weather to be sure. My friends well head froze so they have no water except snow melt or driving in to town, and neighbors all around them have burst pipes. (Water expands when it freezes which causes pipes to expand and sometimes split. Then when it gets above freezing, you have leaky pipes. Not good.)
This same freezing weather wreaked major damage on California crops too. Global warming doesn’t mean everything gets hotter, it can also mean abrupt and severe weather changes of all kinds.
