That wasn't an issue, but I'm glad we're all cool again (or maybe warm
).

Does CO2 affect climate ? Yep. Maybe in ways we don't even know yet because we focus on others.
Does man create more CO2 ? Yep. That stuff about "volcanos making ore CO2 than us" is a nonsense smokescreen of rubbish.
Do man's other activities affect the climate ? Yep - we have cleared trees to make farmland, dammed or changed the courses of major rivers even connected seas together. We have even removed mountains to make mines for things we can only make into jewelry or store in bank vaults - how mad is that ?
When mankind moves into a wilderness it never improves it.
Has man's creation of CO2 contributed to warming ? Probably, it won't have reduced it any. But then again how much given it has been warmer and colder before ?
So what is being "denied" ? Well it is the missing C in front of AGW - "Catastrophic", or even the sometimes used D for "Dangerous". So lets go with those questions :
Are today's temperatures unusual ? Maybe, we don't know. History suggests not - at least on a questionable local level (MWP / LIA). More open science please.
Has CO2 been higher ? Yep.
Has CO2 been lower ? Yep.
Does CO2 drive temperature ? Maybe. "Basic physics" says yes but evidence suggests only maybe. It also suggests strongly that CO2 follows temp. Needs more open research IMHO.
But what about the 20th Century Rise ? Well it could be CO2 from the Industrial Revolution or it could be warming from the end of the LIA or it could be a combination of both.
But what about the "Pause ?" Well you tell me ? Scientists said when the pause started in 1997 that 16 years would be the limit before the models would be invalid. They chose the start and the parameters, so are the models now invalid ?
