What caused Pleistocene to start around 2 million years ago which had periodic glacial interglacial periods?30-01-2019 18:48 | |

Was it because of lowered CO2 level due to fossilization of plants? https://en.wikipedia.org/wiki/Pleistocene Edited on 30-01-2019 18:50 |

Huh? As the ice retracted due to the Milankovitch Cycles and the Solar Cycles and the fact that during an Ice Age there is little to no humidity in the atmosphere and hence NO CLOUDS, plants life grows rapidly. Over the eons this has reduced our original atmosphere of 40% CO2 to 0.04% CO2. As the ice sheets retreated, what was left behind was extremely heavy forest. This supported very large animals. As these heavy forests used more and more CO2 out of the atmosphere they started to die off due to the rather inefficient use of the carbon. So as the CO2 levels dropped more and more heavy forest was replaced with thinning forest and then with grasslands such as the Great Plains and the African Savana. These supported only smaller animals though some animals were able to evolve to present conditions such as the much heavier and large Mammoth evolving into today's Elephant. And the African elephant being threatened with reducing forest for which it is designed. As the atmosphere returns to "normal" temperatures oceanic water solubility for CO2 reduces and CO2 is released into the air by the oceans which cover 70% of this Water Planet of ours. What man is doing by using fossil fuels is releasing the imprisoned carbon back into the atmosphere where it belongs. It could be argued that man COULD release too much into the atmosphere with his over-population of the globe. But studies show that man strikes a balance with nature at certain population densities compared to his own comfort - families used to be large in order to support their aging members. With the wealth of the globe due to easy access to energy, they no longer need that and every country that reaches this level of comfort indeed greatly reduces family size. Mother nature, or God if you prefer, knows what is going on and can and will reach a balance in which the man generated CO2 is in balance with that plants use. |

The cycling of the glacial-interglacial periods during the pleistocene was definitely correlated with Milankovich cycles, but those cycles also occurred before the glacial-interglacial sequence began. The most accepted explanation for why he glacial-interglacial sequence began has to do with plate tectonics, with the last necessary event being the closure of the connection between the Atlantic and Pacific oceans where Panama is now. That would have altered ocean circulation. Most accepted explanation, but maybe not the correct one. The really slow drawdown of atmospheric carbon dioxide since the Cambrian by the burial of the remains of organisms was also a necessary factor, no doubt. |

Wake Actually, large families were traditionally the result need for cheap labor, alcohol, and lack of birth control. Back when currency was still worth more than the paper it was printed on, life was hard work, people grew much of their own food, raise stock, basic transportation was walking, or horses. People did their own construction, repairs, and maintenance. The more kids you had, the less work a parent had to do, many of the daily chores could be put off on the kids. You don't get a choice on gender, well not back then anyway. Don't really understand how it's a choice now, but a lot of that progressive liberal stuff doesn't make sense. Anyway, you need a few kids, and a couple of backups couldn't hurt either, since there were accidents and illness, and ObamaCare hadn't been invented yet. Actually, most did their own healing, best they could, and could only hope to get to a doctor, if something serious happened. What do you think adults did, before cell phones, cable TV, video games, internet pornography? Besides, there is a genetic need to breed, spread your seed. The more offspring you produce, the more that will survive, to contribute your attributes to future generation. We aren't that different from any other species, in that regard. |

still learning wrote:Tai Hai Chen wrote: I would expect your last answer to be correct. Plants started growing very rapidly after the formation of the Earth. But with a CO2 level of 40% of the atmosphere animal life could not exist even in bacterial stages. Over eons of time growing plants could not rot and reconvert to atmospheric CO2 completely due to the only means to do so were molds and parasitic plants. This allowed vast amounts of plants to become buried with incomplete reversion. With each plant that was buried under layers of other plants more and more CO2 was removed from the atmosphere. Remember that CO2 is the combination of one atom of carbon and two atoms of oxygen. In this early atmosphere the ground pressure of the atmosphere was a lot higher than today because CO2 is a heavy molecule. So with a CO2 density that high the levels of nitrogen near the ground were low and the levels of CO2 were probably very high with minimal mixing. So CO2 was worked out of the atmosphere to the levels at which animal life could exist. Bacteria evolved into reptiles and reptiles evolved into small and relatively minor mammals. Then we had the first major extinction event. This is thought to have been either a large meteor strike of a super-volcano that essentially stopped all plant life and hence caused the reptiles to starve to death if they weren't freezing to death from all of the Sun's emissions being held to the far upper reaches of the atmosphere and radiating back into space instead of warming the hard surface of the Earth. All through this time animals were converting carbon from their food supply - plants - and their O2 intake from the atmosphere back into CO2. So after the age of high CO2 levels the Earth began to find a balance of plants converting CO2 into oxygen and vented into the atmosphere and using the carbon as buildihg blocks for the plant tissue and animals converting O2 into CO2 and therefore having to have an input of carbon to arrive at these conversions. But every day slightly more plants were buried to not reconvert to atmospheric gases and the carbon of their forms became fossil fuels. Animals consume hydrocarbons to have materials to generate energy to find more hydrocarbons. Hydro-carbons of different types are the building blocks of all Earth's life. Well, 99.999999% of them. They have discovered some deep sea life forms that are silicon based. But these could not evolve because the elemental interconnections of silicon are far too few. |

Plants are fairly complex, doubt they were the first life forms. Likely it was bacteria, or similar single-cell critters. Then, maybe molds and fungus, sort of in between plant and animal. Everything else evolved, by being better at feeding off the environment, or better at not being the meal, least long enough to reproduce. There is also the biblical explanation, the big guy in the sky, experimented some, before planting the garden, and creating mankind. The big flood was to get rid of some of the weirder or stuff, and get a fresh start, for his better work. Then, there's the extraterrestrial origin of life. Either some space aliens stopped by, partied for a while, and left a few seed-soaked towels and sheets behind. Or, a chunk of a destroyed inhabited planet slammed into our planet, leaving so DNA behind. |

If, and only if, a theory is able to withstand such tests intending to destroy it, and those tests are definable, specific, and produce a specific result, then that theory can stand on more than just a simple circular argument. It is now a theory of science. Science does not use supporting evidence at all. It is only interested in conflicting evidence. The theory itself is all the support a theory of science needs. No theory of science is ever proven. Indeed, no theory at all in an open functional system is ever proven. Religions are best defined by their common properties. All religions are based on some initial circular argument, with arguments extending from that. In Christianity, for example, that initial circular argument is that Christ exists, and He is who He says He is. All other arguments in Christianity stem from that initial circular argument. The other name for the circular argument is 'faith'. Hence, I refer to those that believe in 'global warming' or 'climate change' to be members of a religion. A fundamentalist style religion at that.

HarveyH55 wrote: Certainly it is a guess. But an educated one. We know that the Early atmosphere was composed of Nitrogen and CO2 and we can tell the ratios by geological estimations from the sorts of rocks that formed. We can also tell much by knowing the compositions of the atmospheres of Venus and Mars. Venus has an atmosphere of over 95% CO2 and Mars the same. We know that the Nitrogen from the formation is still in the atmosphere because it is an inert gas. So the percentage of other more active gases can be approximated fairly closely. Remember that above I noted that when you have a very high percentage of a heavy gas and a light one that the heavy gas would not mix well with the lighter one. This means that the surface levels of CO2 were much higher than that at the tropopause. From an approximated atmospheric level of 40% CO2 I would estimate the surface levels of about 60%. Also Oxygen was nearly non-existent as we also can tell from geological studies. This means that NO animal life even as low as bacteria could exist. While today after eons of time we do have bacteria and other one cell organisms that can exist in very high CO2 atmospheres this is from millions of years of evolution under very heavy competition. As I said, a theory yes, but an educated one. |
