"No such thing as climate change" ,,,,,, You are demonstrably wrong there. Climate does change. There is a wealth of historical evidence to demonstrate that. What we haven't managed to do is work out the science of what makes it change well enough to know with any certainty what percentage of the change 0% to 100% is due to human activity.
Anyone who claims either 0% or 100% with religious fervour is almost certainly wrong.
