C02 and methane have nothing to do with ice ages. CO2 rises as the oceans warm, just like a warm soda looses its carbonation. Thus CO2 trails temperature increases.

@@Jc-ms5vv Study more science. CO2 is plant food and crop yields are at all time highs. Plants require heat which is why they are grown in greenhouses. You must be able to reason.

@@thegeneralist7527 photosynthesis starts to drastically slow down at 104f. We’re pumping c02 into the atmosphere ten times faster then the petm extinction event. Compare previous mass extinctions to the rate of this one. When we lose the arctic ice we’ll lose the ability to grow crops at scale. sTuDY MoRe ScienCe

Of course, many things are currently unknown. Of what scientists have found, the thermohaline circulation has much to do with the Ice Age.

The notion that cold oceans drive ice ages is interesring but opposite to science. In fact it is the other way around: ocean currents temperate the climate. The cold carried by currents is leaking, there's no exponential change. Here's the real physics. An ice age that covers land with ice requires at the same time oceans very warm to produce sufficient clouds and to transport them over lands - and lands very cold to make it not rain, but snow, and to keep it frozen and add to the ice mass. If the whole globe had cooled down, the oceans would have frozen and lands would have been ice-free. There's no known mechanism that leads to a CO2 concentration difference between oceans and lands, a so drastic to have the ice age effect. The "great CO2 impact" includes the loop: way more CO2, a little warmer oceans, more convection, more clouds, more greenhouse MOSTLY BECAUSE OF CLOUDS, more CO2 from oceans. The CO2 itself has a so little effect, if all CO2 disappeared from the atmosphere, the temperature wouldn't drop more than 1 degree. The small changes in CO2 we observe have a negligible effect. And the same about methane etc. Low clouds build up from a warm moist air convection - they weren't there when it was warming up, but when they're in the sky, they are responsible for MOST of the greenhouse effect. This is why the mornings are cloudless, but the noons are clouded by cumuluses, and this is why the cloudy night is warm and the cloudless is not. The low clouds are incapable of creating and ice age, because they depend on the warm air. They are stuck in the loop: less low clouds - more heat from the Sun - more convection - more low clouds - less heat from the Sun - less convection - less low clouds. The heat stuck below these clouds is leaking out: you can't have a perpetuum mobile of it, you can't have an exponential change. The elephant in the room are clouds in high atmosphere. They don't let the Sun warmth in, and they cool the Earth down - just like volcano or nuclear dust. High clouds concentrate around particles present there: the ionized cosmic dust makes the difference between the warm and very cold periods. The weaker the Sun and Earth magnetosphere, the more particles get through, the more high clouds, the colder it gets. They are responsible for "nuclear winter" looking events. The exponential cooling stops when the cosmic influx drops down. Please don't fake-darken your voice - I bet your natural, relaxed one sounds way better. Your presentation was a lot of work - superb graphics!

All rain falls as snow … it’s only when it reaches warm enough air it melts into rain.

@@ulazygit good point about Low clouds and High clouds being different! The CO2 related IR absorption takes place to a great extent, 90% or so, in the first 30 meters above ground; I read somewhere. Another factor to be considered is that more mol_mass "CO2" is absorbed in the ocean water than in the atmosphere, it is a chemical equilibrium balance; and then come the green plants, doing their thing!! CO2 < ----> CaCO3, Calcium carbonate, CalciumHydrogenCarbonate in the water!

CO2 is not a factor in either global cooling or warming. Global warming and cooling have always preceded (avg. 600yrs) large increases and decreases, respectively, in atmospheric concentration of CO2. CO2 changes are a result, not a cause, of global temperature changes.
