Read here. IPCC climate scientists claim that increases/decreases of CO2 are the Earth's principal driver in climate change. Study after study proves that this claim is absolutely wrong. The coral areas surrounding the Tahitian islands have recorded pre-history climate change and the corals indicate CO2 changes are irrelevant. The prediction failures of IPCC climate models can be blamed on the incorrect model assumption that CO2 change is a "cause," not an "effect."
