Just recently read a summary report that conclusively ties surface temperature fluctuations (warming and cooling) to El Nino and La Nina. This is scientific fact and the beyond debate...kinda’ like the Climate Change hoax is “settled science”, which ain’t so settled anymore.
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).
