Variations in Earth's orbit (Milankovitch cycles)
The Milankovitch cycles are a set of cyclic variations in characteristics of the Earth's orbit around the Sun. Each cycle has a different length, so at some times their effects reinforce each other and at other times they (partially) cancel each other.
Milankovitch Cycles
Past and future of daily average insolation at top of the atmosphere on the day of the summer solstice, at 65 N latitude.
There is strong evidence that the Milankovitch cycles affect the occurrence of glacial and interglacial periods within an ice age. The present ice age is the most studied and best understood, particularly the last 400,000 years, since this is the period covered by ice cores that record atmospheric composition and proxies for temperature and ice volume. Within this period, the match of glacial/interglacial frequencies to the Milanković orbital forcing periods is so close that orbital forcing is generally accepted. The combined effects of the changing distance to the Sun, the precession of the Earth's axis, and the changing tilt of the Earth's axis redistribute the sunlight received by the Earth.
What the G****l W*****g advocates are purposing is that Mankinds burning of F****l F**ls have disrupted the Natural Cycles so much, that the Earth can never recover and keep getting hotter until the the complete extiction of Humans 9AOC says in 12 years.) The Cockroaches, Termites, and Alligators will survive but expect a large die off of spieces.
There is the forgone fact that eventually mankind will become extinct. Whether it is by human activity or Natural Causes the end is coming. Migrations of people living along Coastal Regions will be forced to move inland. Wars, Famine, Panic, and complete breakdowns of Civilization will occur.
Then again, Cooling could plunge us into the next Ice Age and people would be migrating away from the cold down to a warmer region. Again civilizations trying to survive with Nature.

A great post, i have heard about a bit of what you mentioned, Venus l think was like Earth once but got hot, it got real hot, I don't make the association to virgins but many do, and have done so for a long time, the venus fly trap only recently got rebranded as honey trap because the Spies Union came down very hard asking the spy chiefs' for a better working image of their operatives.
But I will go read that article which I posted, I knew about it because I heard NASA was tying the axis drift to man made c*****e c****e.
I watch "PBS Space Time" channel, I think "Is an Ice Age Coming". represents my understanding of the situation up to a point.
At the moment were in a brief interglacial stage that should be a short period compared to the cold period, the warm period we're in is known as the Holocene period which started 11,000 years ago but the cold periods preceding this lasted 7 times longer, that's
a ratio of 1warm year to 7 cold years, this sequence of events began 400,000 years ago.
And I've heard before that we should be going back into a long cold period, but we're getting hotter instead of colder, which is the problem.
Glacial ice cores and ocean sediments tell the story, the oldest ice core trapped gas 800,000 years ago, and our present cycle of ice age chemical and isotopic history dates back to 400,000 yag when something changed the previous pattern.

So a we now represent a warm interlude in the middle of an ice age that is probably being affected by a "non build up" of reflective snow and cooling ocean temperatures.
With Carbon at 400 ppm.+, representing the possible causation of a game changer that could recalibrate the cold moderate equilibrium to be a one way ticket to hell we should be concerned and taking action.
Particularly in view of the Venus example, because the original model that changed 400,000 y.a.g. to be the one we we are blessed with since Earth warmed up 11,000 y.a.g. Is based on snow and ice build up causing cool oceans and massive reflection of heat back into space.
If this cold build up doesn't happen the Mailankovitch climate cycles instead of going from an climate period having a ratio of 12,000 years moderate to 84,000 very cold to become the opposite, hot 12,000 years to extremely hot for 84,000 years.
This interdependence of environmental factors is already well understood with rainfall in Australia affected by the El Nino climate cycle.
I'm not sure if anyone from the scientific community makes this El Nino connection.
