Here in New England I’ve witnessed “most” of what Mother Nature can throw at you. I’ve experienced a range of summer conditions, including “hot, humid” summers, cool summers, Wet summers (catastrophically), and drought summers, where reservoirs and people’s wells are nearly dry.
Winters, the same, cold winters, not so cold winters. Lots of snow, not so much snow.
Human lifespans are to short to comprehend changes that can occur over the course of centuries. I would not deny that human activity can play a role in the climate, but the science of climate has become so politicized that anyone questioning certain tenants are labeled deniers. But it’s not about “saving the planet”, it’s about who will control the masses when people will “own nothing and be happy”.
“Civilizations depend on reliable aboundant energy. When it needs to be rationed by the powers in charge it becomes another milestone on “The Road to Serfdom”.
