Cool clip! But one hypothesis u have is that CO2 should decreaes 800 years after the end of medieval warmth. If it does (it may do so) we first has to remember we already have a 30 or 40 percent increase. That won't be compensated for. 2nd: If you think less CO2 (which will never be the case compared to natural levels) decrease temperatur, the TGGWS-theory that CO2 is not a big Climate Change force is false. Regarding the sun argument I'm with you!
Q1: I believe you are referring to temperature rise after 1985. This is controversial. Sceptics claim it does not exist, only appears because of the "hockey stick". Even if assumed true, most is due to the oceans because they are emitting CO2 in response to the MWP. So the 30-40% increase, if it exists, will be easily taken up by the oceans as they cool.
Satellites messure atmospheric temp since 1979 more accurate than before. Therefore we knnow we have 0.2-0.3 C increase since the 1970s. Hockey stick don't change that.
More problematic is 1880 to 1979. Up to 1/4 could be Urban heat and up to 40 % land use change. More than half of the increase shall be correct. Good you're thinking!
Q2: I believe you are incorrect. 90-95% of the greenhouse effect is due to water vapour. Only 4% is due to CO2 and its effect flattens off rapidly as the amount of CO2 in the atmosphere rises. This means that TGGWS claim that CO2 is a small greenhouse gas is correct. Nevertheless, it has some greenhouse effect and, whatever it is, will be severely reduced as the oceans cool.
