“The problem is we don’t know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books—mine included—because it looked clear-cut, but it hasn’t happened,” Lovelock said.
Still lying for the cause. No one with half a brain thought that atmospheric dynamics were well known 20 years ago.
The first IPCC report was made public in 1990. The supplementary report was in 1992--twenty years ago. James Hansen launched his hoax on Congress in 1988.
