Bought both expansions for Civ VI, even though it turns out you only actually need Gathering Storm.
Bit odd that my first completed game felt, despite plenty of cutscenes showing natural disasters, fairly normal with little overall impact from climate change for my civilisation. It was weird that I was pretty far behind on the science victory track and still managed to win, when the one in the lead refused for whatever reason to do the final task faster than one light year per turn.
The diplomacy victory condition is probably the most interesting addition and better than what I remember in Civ V where it was all based on city states liking you. The best narrative aspect of climate change is being the one to pump out tonnes of emissions and riding to the rescue for natural disasters that you've helped cause. Whether that's intended as a comment on international efforts to combat climate change I don't know.
I like the addition of the history timeline, as playing as Robert the Bruce gave me these:
