"a moral issue on a par with slavery." In case you don't understand the term, that does not mean "worse than slavery."
Now, is the choice to hasten climate change and risk nearly certain catastrophic results in exchange for short-term profit a moral issue on a par with slavery? I think one can reasonably argue that it is, given the level of disruption to the planet, its people, and its ecosystems. Think of it as you making a choice to be a bit more comfortable right now while upping the odds that your grandchildren will die horribly in 60 years and maybe that makes it simpler.
As for the rest of your shit, it seems much more sensible to pay attention to what scientists who spend their lives studying this stuff have to say rather than some guy quoting Wikipedia on the internet and using dumbass terms like "warmists" that probably originate from talk radio.
