Tobis: Ok, so maybe CO2 isn't warming the air lately, but it is allegedly causing “the wrong air at the wrong time” to be delivered to large areas

Global Warming Does Not Cause Climate Change | Planet3.0
Carbon dioxide (CO2), on the other hand, while freely exchanged between the ocean and the atmosphere, requires a very long time to exit the system. Conceptually, it is not a terrible approximation, on the timescale of a human lifespan, to say that it doesn’t go away at all; at least not on its own...Each of these was associated with a phenomenon called “blocking” wherein the the stream develops huge, sluggish meanders, delivering  to some large area. There is considerable evidence that this phenomenon has become more prevalent in recent years.
[Regarding Tobis' claim that CO2 "requires a very long time to exit the system"]: Segalstad CO2 Experiment Video - YouTube
This video shows that a candle floating on water, burning in the air inside a glass, converts the oxygen in the air to CO2. The water rises in the glass because the CO2, which replaced the oxygen, is quickly dissolved in the water. The water contains calcium ions Ca++, because we initially dissolved calcium hydroxide Ca(OH)2 in the water. The CO2 produced during oxygen burning reacts with the calcium ions to produce solid calcium carbonate CaCO3, which is easily visible as a whitening of the water when we switch on a flashlight. This little kitchen experiment demonstrates the inorganic carbon cycle in nature. The oceans take out our anthropogenic CO2 gas by quickly dissolving it as bicarbonate HCO3-, which in turn forms solid calcium carbonate either organically in calcareous organisms or precipitates inorganically. The CaCO3 is precipitating and not dissolving during this process, because buffering in the ocean maintains a stable pH around 8. We also see that CO2 reacts very fast with the water, contrary to the claim by the IPCC that it takes 50 - 200 years for this to happen. Try this for yourself in your kitchen!
