If you question the IPCC:s doomsday models doesn't mean that you are denying environmental problems. Same as the whole world who locked down because of Neil Fergussons botched covidsim model.

He’s studied the effects of natural events like volcanic eruptions and how they have helped to balance planerary temperature. Solar geoengineering is an interesting possibility, by no means the only way to mitigate the effects of atmospheric carbon. I have seen no hysterics in his argument, just a search for truth.
