200 and something years may seem too much to mankind, but for the Mother Earth is just a glimpse.
Actually, historically that was just around the corner for the mini-ice age that we suffered after the last time the Icelandic volcanoes had some indigestion. Right after the medieval warm period.
Wish an actual climate change mod existed. A "Mother Gaia is having a fit of pique and guess what, it's now warmer/colder, deal with it" sort of affair

Would be fun to have to adapt when all your wineries have to be closed because it gets too cold, but you've now got better fur resources as all the furry critters migrate south to avoid the really cold stuff further up north. Then when you've got your economy going as the fur emporium of the word, things warm up again
When it gets cold, plains turn to tundra, tundra to ice, grassland to plains. With only a thin belt around the equator staying in grassland and jungle. Also, coast becomes bogs/wetlands, and ocean becomes coast.
Then, during a particularly warm period, you have the reverse, with some normally coastal land tiles becoming inundated (marsh? bog?), and you need to build a flood-control system in any cities on those tiles or lose them.
