Predictive assesments, so far in form of analogies, have been made: Because the solar motion in the next decades will be chaotic, lower and longer solar cycles (with irregular length), ocurrence of
huge volcanic events and a decrease of global surface air temperature can be expected.
Not exact matches
I've sometimes thought that global cataclysms like the largest
volcanic eruptions would disrupt the glacial records by many years, like Oruanui eruption c. 26500bp, as these would induce unrecorded behavior in weather and other things, f.e. the
huge ash deposits might decrease the albedo so much a local melting
event happens.
Then throw in massive
volcanic eruptions and
huge continent wide brush fires caused by volcanoes or meteor showers (both theories I have seen in the literature) and you have many
events that could cause climate disruption on a large scale.
