Climate also doesn't change in macro over a lifetime.
It's very real, but the notion that it's changing over a 5 year period is nonsense.
things aren't "shutting off".
Looking back at the amount of snowfall I saw as a kid and the amount of snowfall I see now in my 30s, or at the number of hot summer days ... I find it hard to claim that climate is not changing over a lifetime. 20 years isn't even a lifetime, that's like 1/4th of a lifetime
Maybe climate is more stable wherever you live
I refer you to: https://xkcd.com/1732/
Huh? Sudden events are a very real part of larger processes like evolution and climate change. A volcano eruption, a meteor impact, or a drought year, or the ceasing of a current can absolutely have massive implications on larger systems.
Wishful thinking...
I wonder how people like you end up so hostile to experts.
I am old enough to have witnessed how the climate has completely changed in Europe, where I live.
In the same place where I live now, when I was young there was permanent snow cover for 3 to 4 months.
During the last 10 years, there have been years with no snow and in the others a little snow has been present for 3 or 4 days of a year, when it melted the second day after falling.
I have not used again my winter boots and my winter jackets for the last 15 years or more.
This is really a huge change during less than a human lifetime.
