Technically we are still in the last Ice Age, until the poles are free if ice, we are still in it.

Changing the goal posts. Nice.

[@paulkysar6207]

​@@Encephalitisifynot really, it's a fact.

[@revolutionaryhamburger]

@@Encephalitisify For 90 percent of its existence, Earth was ice cap free. Greenland has ancient trees and elephant bones buried under the ice sheet. Antarctica once was cover in jungles. Earth today is much colder than normal.

A single-celled organism being able to crash the whole world's ecosystem sounds more familiar when you consider that single-celled organisms were the most complex life form on the planet at the time. The most complex life form on the planet still has the ability to crash the planet's ecosystem.

I would have thought it was a near certainty, the last ice age only ended about 10,000 years ago and it's cyclical

[@harrietharlow9929]

It generally is cyclical, but because of climate change that date has been put off several thousand years. Normally, from what can be ascertained, an interglacial has generally lasted 10,000-12,000 years.

[@rogerwilco1777]

Yeah.. basically a 10-15k yr cycle.. but the earth doesnt 'completely' freeze over in those times.. like 30% or more of the planet.. 100% has only happened about two times in earths history.. (one of those lasting 15million yrs).. The rapid acceleration since the 1970's is well beyond the natural scale., so if we're cant figure it out, then we might trigger another one of those snowball earth situations and there will be no safe zone for any human, or most of life as we know it, for potentially millions of years.

[@jpjh8844]

well that is because you were misinformed!

[@MarinCipollina]

The cyclical ice ages are a separate cycle than the prior examples of a snowball Earth we're being asked to consider. The snowball (Or slushball if you prefer) were much rarer events, happening mayb as many as 3 times in the past history of the planet. 2.20 billion years ago in one example, 650 million years ago ini a subsequent example and I did not hear mention of any time frame suggestion for the third snowball example. The more typical and less severe more typical ice age glaciations happen at roughly 80k - 100k year periods.

Straight to the comments .

[@mamasimmerplays4702]

"The ability to convert carbon dioxide into oxygen using the sun's energy" misses completely what plants actually do. They convert carbon dioxide and water into sugars, using the sun's energy, and then use these sugars to grow. Oxygen is released by this process as a waste product. They're not trying to produce oxygen any more than a gold mining company is trying to produce tailings dams. It's just a waste product they're dumping in the ecosystem and hoping someone else will clean it up for them.

[@CJ_Ludwig501]

This isn't an argument for or against the snowball earth theory, but Professor Alan's argument against the theory is flawed. Wind isn't the only mechanism that would create ripple effects on the sea floor. Water currents also create ripples on the sea floor, and those are created by the Coriolas Effect and tides.

"it's unlikely that mankind will be around to witness another snowball Earth" That statement leaves a lot to ponder. Is the author saying that we are unlikely to survive or that we will all be living on other planets? Today, we have a much greater hope and need to be an interplanetary species. A million years is a long time for any species to survive. Yet, we are extraordinary creatures of intelligence and ingenuity. I believe we will survive for much longer.

[@mamasimmerplays4702]

Do we have evidence from more than one location for each episode? It's not inconceivable for ocean currents to carry icebergs along a particular path fast enough that they get to the equator before they melt if the world is in normal ice-age conditions - it doesn't need to be full snowball. Also, the presence of dropstones in multiple layers kind of proves that the ice was routinely melting at this location - which is not full snowball anyway.

[@PeterDClack...]

There is plenty of science explaining the snowball earth ice ages. But whoever wrote this show couldn't be bothered finding out.

[@DVR01]

I would like to witness the 2nd Ice-Age will happen where these details would happen for many years to come, for example, while we'll all make the best of everything: 1. Each and every last wrestling company and their Pay-Per-View shows, including the WWE (the World Wrestling Entertainment) and WrestleMania, would each end up with literal-zero fans in attendance, where it is like having the shows to each and every one of the fans 2. All animals, including the marine and mini ones, each had to be vaccinated with anti-freeze by many camouflaged-drones’ needleless syringes to avoid extinction and become adapted to the powerful second ice-age while being fed by veterinarians 3. Like the COVID-19, everybody had to be inside their homes and would order drinks and food online and then delivered, live-action movies and series, including Doctor Who, were to be released online early while others being filmed had changed to be winter-snow themed while many voice actors and actresses at films and series, Anime included, would still voice their respective characters from their homes, famous bands, musicians, singers, and rappers would perform at-home concerts 4. Every last freight and minor passenger trains, each with snowplows, were still in service while flights and cruises would be cancelled until Anti-Freeze will work on each vehicle 5. Schools, Colleges, Universities, Trials, Funerals, Weddings, etc. would instead take place online 6. Many outdoor live shows, including Dick Clark's New Rockin Eve, would be altered Etc.

Most understand that, particularly the scientists who study it. What's new is emissions from human activity - not weather or climate. A species with a massive population that's literally reshaped the surface of the planet. But you don't need to be a scientist to understand that introducing new factors in a relatively closed system will have abnormal effects on the cycles in said system. Life in all its different evolutionary forms has been affecting systems on this rock for millions of years, for good and for bad. Those that didn't adapt died out. The planet doesn't need saving. You do, especially with that comfortable delusion you're living in.

These scientists go on about carbon dioxide and methane warming the atmosphere but I hear nothing about air pressure. Has it decreased? During warmer periods millions of years ago atmospheric pressure may have been much higher and hence the temperatures. It hasn’t been discounted that the recent global warming has been caused by undersea volcanoes heating sea surface temperatures, water vapour and world temperatures.

This was posted 7 days ago. The bacteria was in a battle. The first forms of life couldn’t photosynthesise then new forms of life that spread through the sea and changed could photosynthesis,they produced oxygen as waste. Oxygen was a killer to the old forms of life and so on and so on until the earth balanced out. In between all this it caused ice ages. I watched a documentary about how the first forms of life was in a battle and the gasses,oxygen ect. It was the atmosphere because of all the gasses and dying life forms that caused the ice ages.

But no pterosaurs. An older life form that had been evolving much longer. Didn't make it when it had a longer run so must have not been able to adapt like feathered critters did. In fact the feathers might be the answer. Ability to fly, ability to have warm clothing. Some factor doomed the pterosaurs, which might have been feathers.

Poles shifting only completely this time and of course it's still over a matter of time. But south pole will become North Pole and the north pole will become the south pole.

[@HepCatJack]

They've happened before. They can happen as often as every 10 thousand years or so and as infrequently as every 50 million years or more. We can see evidence of magnetic polarity reversals by examining the geologic record. When lavas or sediments solidify, they often preserve a signature of the ambient magnetic field at the time of deposition.

@@HepCatJack North and South Poles have shifted yes like normal but they haven't shifted in totality entirety of the physical north and south poles. I'm not sure how to write it so you can grasp or fully comprehend what I'm saying but this is my last attempt at it since it's a complete waste of my time trying to explain it to you. I usually just explain to the people who really want to know not some random person who may be one of those types of people that wants to be right all the time or strictly fact driven even though not everything in life is factual or science based knowledge. The key is " entirety ". The poles have never shifted in their entirety, but yes they have reversed and shifted as normal but not in their entirety. Have a good day.

Nature would have already have made this occur by now. Weather modification has been active for decades, with the first Military conflict involving such technology, taking place during the Vietnam era in the USA's history. Truth about Global Warming and mini Ice Age's occuring, relating to evidence from Milinkovic cycles, doesn't cater for the fact that our weather is artificially controlled and has been for a long time.
