the science is advancing. it's just the media doom porn and political manipulation. we are definitely heading for a cooldown. not in our lifetimes tho, probably maybe up to 1000 years or so.
what is more pressing and growing more certain is that there is a magnetic reversal coming, the earth's magnetic field is being interfered with and there is also good evidence for the idea that it could cause a catastrophic slip of the earth's crust to match the new magnetic field orientation emanating from the rest of the galaxy.
this slip could explain what happened in the time of Noah, and it generally does often lead further to a large number of big rocks forming after the sun has a giant burp caused by its own magnetic field reorienting to the new phase. then those rocks hit everything and stir up a lot of dust, and meanwhile earthquakes and volcanoes fill the atmosphere with dust and shade the sun.
there is of course much differing theories about it but i'm convinced that the global flood did happen, too many disconnected societies reported similar events, and 12000 years ago very old stories about "fiery dragons streaking across the sky" and the sun turning blue and "evil" and people dying. these all fit with the superflare/micronova scenario, and the geomagnetic shift is definitely happening.

the one thing for sure, that you can see easily looking at that path of the magnetic north, is that it's accelerated in the last 400 years how fast it moves.
when this happens, the magnetic shield of the earth stops working and a lot more energy from space and the sun gets into the atmosphere, which usually leads to more storms, rain, earthquakes and volcanoes. and if it does go towards the current equator, then it is even worse than that - much of the habitable parts of the planet will be exposed to a lot of ionizing radiation as well on top of all the rest, meaning that there will be mass die-offs of forests and people will die (most often from radiation sickness and cancer).
there is a whole slew of discoveries around magnetic pole orientation preserved in the volcanic formed rocks that eruptions happened more frequently during this time, and further, it is this periodic increase in radiation and CMEs that causes a massive jump in the amount of Carbon 14 which completely destroys the validity of carbon dating, because some of the fossils (probably all) form during times of high solar flare and low protection from plasma flying away from the sun that the concentrations of C14 are massively increased during a short period. thus you can't use C14 ratios as a reliable measure of time because we haven't fully characterised the deposition rate of it.
the 6000 years of earth thing probably is a reference to a periodic reversal and even, if you think of the first chapter of genesis, it could describe the situation from the beginning of the global flood (after all the crust shifts, and all the land is inundated) and then slowly over days, first, the water starts to part over the land, the clouds clear on the second day, third day, then the fish and animals crawl out from their holes in the high ground, and so on and so on. possibly genesis specifically is describing what happened 12000 years ago, and then after that, we have adam, and then 6000 years ago noah. also, it was not long after that, that sodom and gomorrah got hit with probably meteors and similar catastrophy on babylon. i do think that the global pole shift does happen every 6000 years though, and for about 1000 years after it, everything is bad, cold, cloudy, and nasty stuff falling out of the sky.
