Back in the aughts, a specific prediction of flooding in the NYC subway system in a decade was made. And then in 2012, Hurricane Sandy hit the area, flooding the subway, completing that prediction. It's now 2023 and NYC is flooding again.
Or how about wildfires turning the sky orange. Fire existed before global climate change, but it's made the fire season longer and fires more frequent. Fires in Canada made the sky's orany for much of the North Eastern US. It's pretty hard to ignore the sky being the wrong color.
Objectively, yes, things have happened.
