All pictures will be able to be found here: el-d0rito.deviantart.com Most future evolution projects take place in the more distant future, over 5 million years away. But life can evolve and change over much shorter timescales. This especially applies after extinction events. Only a few hundred thousand years after the K-Pg extinction, Palaeocene mammals had already become larger than any known Mesozoic mammal. Today, a similar, though as yet less severe extinction event is taking place. Already most of the megafauna that existed for the past several million years have gone extinct, leaving niches open. The only things keeping them open are human activities and time. But history and common sense tell us that at some point in the next thousand years our planetary civilisation will probably collapse, largely eliminating the main factor stopping life carrying on. Fast forward 1 million years, and the 'wild' is again the normal state of the earth. The oceans have risen some 80 metres due to human induced climate change, for the same reason most of the worlds ice is gone too. Several super volcanoes have erupted, and the last remnants of the modern 'concrete jungle' have crumbled. Humans are rare, and are considerably different to 21st century people. They are no longer a significant force effecting the earth. Some groups of animals are identical to those we are familiar with, some are similar but obviously different, and a few are unlike anything found in the modern era. This is the world in 1 million years AD. Edited by El Dorito, Jan 5 2016, 08:55 PM.

I thought it was almost common knowledge that the ice caps were going to melt. Maybe they won't right now, but the earths temperature is lagging behind the temperature it could get to with 400 ppm of CO2 in the atmosphere. Last time there was that much CO2 in the atmosphere there was no Greenland ice sheet or west Antarctic ice sheet, and about 2/3 of the East Antarctic ice sheet was melted in addition. They recently found that the massive Totten glacier of the Wilkes land region of East Antarctica is also grounded below sea level and is melting. The Totten glacier basin drains between 1/4 and 1/3 of East Antarctica. What is often ignored because it is a distant future thing is that much of present Antarctica and Greenland are below sea level, but glacial rebound would push most of that shallow ocean into the deeper ocean basins around it, probably causing a comparitively small but significant additional rise. There are a lot of variables that are often ignored. 1:http://www.theguardian.com/environment/2015/jul/10/scientists-predict-huge-sea-level-rise-even-if-we-limit-climate-change 2:https://nsidc.org/cryosphere/sotc/sea_level.html Totten glacier: https://www.washingtonpost.com/news/energy-environment/wp/2015/10/26/east-antarcticas-biggest-glacier-is-melting-from-below-study-confirms/ |

One issue that I have brought up before on the wiki (though when I brought it up I was being a bit extreme) is that carbon dioxide is not by a long shot the only factor to affect global warming. Remember that last time carbon dioxide was this high, there wasn't enough ice on Earth to reflect sunlight and cool temperatures. In the Pliocene, Milankovitch cycles did not cause the Earth to rapidly cool and warm. In fact, currently Milankovitch cycles seem to be driving the global temperature slightly upwards independent of carbon dioxide since we are nearing the middle of the interglacial. In the future, the effects of carbon dioxide on the atmosphere may be even less if Milankovitch cycles cool the Earth once again. The effects Milankovitch cycles and the like have on glaciations have not been studied very well, but odds are that yes, in the short term we will be having extreme sea level rises. But a 100 meter+ sea level rise in the future is not necessarily called for due to cooling at the end of the interglacial. Edited by revin, Jan 4 2016, 11:31 PM.

Yes I remember that post, was indeed a bit on the extreme side. I know Milankovitch cycles are a factor, but realistically we are doing much more than a 'superficial' increase on top of what is happening naturally we have proof from ice core and soil analysis that the industrialisation of our civilisation has caused CO2 levels to climb by the same amount as it did at the end of the last ice age. I read somewhere that near the start of the Holocene there was an unusual increase in temperature that didn't happen during the previous interglacials, and which has been linked to the start of agriculture. This in itself wouldn't have stopped the ice ages, but it shows that things were a little different this time around. The effects of doubling the CO2 levels in 200 years is even less understood than the way ice age cycles behave. The earths natural processes don't respond quickly enough to be realised until it's too late. Anyway it's not necessarily the CO2 that's the big worry, if it warms up even a little bit it will melt methane saturated permafrost, and destabilise submarine gas hydrate deposits. The last time that happened there was a thermal maximum and extinction event in the oceans, and such an event is within the temperature range predicted if we don't cut CO2 emissions by half before 2040 or something. In a sense we might actually be alive to watch a thermal maximum happen... Edited by El Dorito, Jan 5 2016, 12:25 AM.

Thing is, there were less than 10 million people on Earth at the start of the Holocene, and even by 5000 BC less than half of the world practiced agriculture. It seems unlikely that such small-scale farming of fairly unchanged plants (corn/maize was domesticated later, and it still wouldn't have had a major effect) would not have a major effect on the environment. In fact, since the plants were not introduced or significantly changed no fertilisers would be used. While it could potentially be linked to farm animals, those were not all that common either. Odds are the sudden spike was due to an unusual variation in the Milankovitch cycles which ended the glaciations in a short period of time. (And humans definitely did not end the glaciations; there's definite consensus that the end of the glaciation caused farming, not the other way around.) I highly doubt that. Even a worst case scenario extreme capitalism and industrialism no alternative energy 'Murcia-dominated society could not cause a literal thermal maximum within the scope of one lifetime. Everything else is fairly valid; it's safe to say there are a lot of unknowns that need to be known to figure out what kind of long-term impact global warming will have on sea levels and temperatures. |

Maybe not in the lifetime of us now, but probably within the lifetime of people born in our lifetime. You might be looking at things a bit too optimistically in some ways. Literally all it would take is a rise of 3 degrees, which is pretty much unavoidable if we don't do something very soon, and all the permafrost and gas hydrate deposits would be destabilised and the whole thing would be out of our control. If you go by CO2 alone, then yes, it wouldn't happen for a few centuries or more, and likely wouldn't happen at all. However most simulations, including 90% or something of publicly released documents, fail to even mention gas hydrate and permafrost methane stores as a serious threat, when in reality it is a much bigger contributed to really rapid climate change than CO2 is.

The thing is that the rapid climate change is going to die down, eventually. I think that we as a species know enough to limit our own carbon dioxide emissions. Even if we don't, that means that we as a species are selfish and likely to kill ourselves within the next few thousand years. A million years in the future, global warming will have had some impact in wiping out species, but the sea levels would not continue to rise 100 meters above the present level. The thing is that the amount of fossil fuels on Earth is also rapidly declining, which means that we cannot even sustain them for over a hundred more years. In that respect, CO2 emissions are already destined to be over. I do agree in the short term things could get fairly bad. But if we manage to survive long enough to have a long term impact, we will have long since abandoned fossil fuels and gotten off this rock anyways. With the beginning of the next glaciation occurring in the next 10 or 20 thousand years, the temperatures will cool down yet more. In the span of a million years, it is unlikely that our 300 or so years of fossil fuels have caused the sea levels to rise 100 meters. Plus, has there been any time in Earth's history that the sea levels has been 100 meters above present? If we were to do this to the environment it might count as the most extreme hothouse environment the Earth has ever seen. |

Weren't sea levels during some parts of the Cretaceous over 100 metres? I'm sure it said sea levels were maybe as high as 120 metres |

I'm not sure, but the what was and was not underwater that far back would've been effected by more than just the water level. Different elevations and continent layouts might make it look like there was more of a different than you would think looking at a map. |

Possibly, but then the sea levels in this project would be close to the highest ever. Also note what Myo said, since during other past time periods there have been higher temperatures and/or carbon dioxide levels. Edited by revin, Jan 5 2016, 07:10 PM.

As I said exactly in my precious post, 300 years of fossil fuels won't do it, but it will warm the earth up just enough to melt frozen permafrost and gas hydrate deposits, as I said twice now. Methane is about 100 times worse a greenhouse gas as CO2, and at that point it becomes a self running machine that we can't stop. As an added 'bonus', after a few years in the air methane is oxidised into yet more CO2, and water vapour. While the effect of this is pretty much unstudied, water vapour is the worst greenhouse gas there is... Maybe the last bit is a bit over the top, but most of it is completely legit. |

Also the idea that we are running out of fossil fuels is a big myth. We have enough fossil fuels to last us for centuries if we can find them. The main problem is that most of them are in the form of oil in the deep sea, where it is hard to get. |

If it makes everyone happy I will change the sea level rise to 80 metres, which is a widely sited number. |

Well if we really want to get technical about fossil fuels, as long as there is life on Earth it can be considered a renewable resource, it just takes a really long time to make them. It's the same way with how solar energy is renewable, but we all know the sun will die eventually. That's not important to this thread, just wanted to say that is all |

I've got a lot in store for the later part of the near future. Just to name a few: An entire order of new marine mammals (well if you go by Linnaean it is anyway but you know what I mean). Giant predatory sharks almost as big as magalodon. Penguin analogue seals because most people go the other way. A family of shark-like marine lizards. Endothermic terrestrial squamates. Flightless predatory birds of some sort. Birds that look like small feathered dinosaurs that are descended from the 'chickenosaurus' experiment, because unexpected is more original. I have more ideas but these are the ones I've thought about and stuff. |
