as you might recall its weather extremes that are the change in climate. we had a pretty ordinary winter until August when it suddenly burst into spring.
I noted the equally sudden change from summer extreme drought in 2019 to wet subtropical rain in Jan 2020. the northern hemisphere had been going ok but from Jan 2020 they began having extreme heat. I don't think air currents move south to north generally but I kinda looked like the hot southern hemi air had moved north and stayed there for 4 years while we had cooler, wetter weather for that duration.
with this sudden shift fro winter to spring in early August I'm suspecting we're in for one hell of a summer.
clearly global warming is having the effect expressed by the physics of the carbon cycle, not by modelling which is imo unreliable.
have a look at the Copernicus LINK. sea ice in north and south is clearly trending down fast.
