Right. But what causes El Nino and La Nina ? There is no significant extra visible light energy arriving from the sun to cause El Nino warming. If they claim it is CO2 caused, why is it cyclic and what causes a lowering of temperature (La Nina).
Not being flippant, but you’ll have to ask God what causes El Nino and La Nina. Even large scale glacial stages that last for thousands of years are related to a multitude of constructive and destructive interferece cycles.
