from the article > "Climate has always changed, and weather is always variable, due to complex, powerful natural forces," Legates said.
it sure doesn't sound like he is "denying climate change", rather he disagrees with the theory that human activity is the main cause of climate change. With the replication crisis going on, I don't mind scientists who question the results of some research as long as those scientists follow the scientific method.
What happened to scientific opinions?
