From the first IPCC reports in 1990, to today, the IPCC's prognostications about the future became more and more clairvoyant. Yes, it wasn't till the early 2000s that there was enough observed multiple sources of information about man-made climate change that they could say that with 90% (later 99%) certainty, but they made clear the future risk. If you look at the early IPCC reports, they made it clear that CO2 was a greenhouse gas, but at least in the United States, the fossil fuel industry fought tooth and nail and spent huge amounts of money to fight a regulatory classification of it as such. It wasn't until 2009 that was. https://www.youtube.com/watch?v=UVz67cwmxTM https://www.youtube.com/watch?v=UVz67cwmxTM
