But I do note that he is a scientist who worked on the reef and he completely disagrees.
I additionally note that he was pretty aggressively silenced and his livelihood taken away, "unfairly" according to the courts. I worry that this is how you get to 99% - crushing dissent through intimidation, and not debating? He says he only spoke up because he was so close to retirement age, and he was only able to achieve a legal win because of crowdfunding. Most other scientists are not in that position - the consequences of speaking up would appear terrifying.
Dunno, maybe he is a complete crank, but you can see how it might give a dispassionate observer pause for thought and a bit of discomfort.
