I clearly do. Hitler killed millions of people, not unlike the Black Death or Genghis Khan, but what can you do, life goes on. Climate change is different. Life will absolutely not go on if we don't start handling it. It's an extinction event, and that's not a hyperbole, we are actually in the middle of the Holocene extinction event, also called the sixth mass extinction.
If it weren't for Hitler, World War II might have been over climate policy instead, and there might be no nukes. You gloss over Nth-order effects and cite a single statistic to compare relative damage done to humanity (spoiler alert: what you actually tried to do here is not possible to scientifically do at all - you are pro-science, right?). This tells me that you haven't done any real research on the topic, but are…
Nuclear weapons were inevitable, they are trivial inventions.
Nobody would have fought over climate policy a 100 years ago. Climate change barely received any publicity before James Hansen's testimony in 1988.
