Maybe related to Q’s “watch the water” drops? Water has waves.
I honestly don't have a clue, but it's not outside the realm of probability. Is Q letting us in on a close held secret? I don't know. I only know from my own personal research that the earth periodically goes through major geological and climate changes on pretty much a regular basis. No one is alive to tell us what all took place. I have a feeling they were pretty destructive/major events. We're due for another ice age and we're seeing signs, like CO2 increases that ice core samples show occur around these periods.
This is a link to a site run by an uncredentialed individual that is actually pretty informative and probably more accurate than most academia/government connected sites pushing global warming agenda for the bucks, etc.
