"There are various tipping mechanisms and cascade effects that some researchers conclude could create far more rapid change scenarios than we now accept."

Where fast climate change has happened in the past it accepted and acknowledged amongst climate scientists, but then no-one is listening to them. Read modern climate science papers.


"The science is far from perfect"

All science is far from perfect, that's why we do research. In the case of climate science this statement is one frequently trotted out by deniers and is misleading. We have solid data on the rapid change of the climate, and we understand any of the reasons for climate variability in the past, and this is not what we are experiencing.


"A scientist, you say? Talking like that?"

Huh?
