The medieval warm period and following "little ice age" are not even visible on the xkcd graph, that's how small they are compared to massive recent changes. You're looking at micro trend with a magnifying glass and macro trend with a distorting lens if you think the medieval events are anywhere close to what's happening. No recorded climate change happened as fast as the current one, there have been wilder changes but they happened over centuries, not decades
Saying climate always changed so it's ok is like saying you'll die eventually so it's ok if you die tomorrow
> better understand that climate has always changed and will continue to change.
I think virtually no one ever argued against that: https://skepticalscience.com/print.php?r=48
