The sun controls the climate of all its planets. Man-made-climate-change is an outright LIE.
The truth is that climate is a long-term chaotic system that has limits to its predictability. There is not even a way to fully test it under the scientific method. We know that it changes constantly, but we don’t know all the causal factors. We can’t just say “C02 does it” like idiots or Democrats. The science is far from certain.
