I think the use of the term 'unequivocal' when discussing this topic is a mistake. Remember, they used to call it 'global warming' until the data proved it was not so they started calling it 'climate change' which is a meaningless term because it is absolutely always true.
Steve Goddard, Judith Curry and many others have challenged some of the things we are told are 'unequivocal' and suffered as a result.
Lots of examples here of bad science being promoted as evidence of global warming/man made climate change. The CO2 lie is one of the worst.
