And yes, there's a fast climb, but it's not the only instance in history, look at 800AD, 200AD, and a lot more in the past, it seems to be the way the temp fluctuates, very sharply. If we get back to the 10,000 years chart, do the last 150 years seems off the chart? If anything, it shows that we're cooler than the last 10,000 years.

A graph that starts at 1840 doesn't show the past 10 000 years at all -- in the long view, that's all just a bunch of noise. What happened to the 'completely different picture' that the 10 000 year view held? Here's the 10 000 same graph with some colours https://i.imgur.com/GWhaGCU.png https://i.imgur.com/GWhaGCU.png Blue periods were colder than 2009. Yellow periods were warmer. The past 10 000 years were mostly colder than 2009, and we've only gotten warmer since then. And... precedent isn't the main issue here. Those large bumps have causes. This time, the cause is us. It's up to us [collectively] whether we want this. Maybe the Roman Period's ~-29.75C represents a better climate for humanity than the 1855 levels. That's right around that '2 degree limit' people talk about. If that's a target, it's about time to transition out of making 'as much CO2 possible as fast as possible'.
