Here's a video I created with Motionleap

I know that once O² levels dropped the large dinosaurs struggled & were on the way out, even if k2 didn't happen 65m years ago. They needed the high O² to power the large frames. This in turn came from high CO² levels or plant food as you say. I have CO² & O² level graphs (random selection) over the past 500m yes. Have a look and see what they tell you.

Interesting. If humans are around millions of yrs longer than the official narrative then our atmosphere suited a larger frame.

They graphs I think really challenge CO² crisis levels concern also.

Nice info as usual A!! How do ppms relate to % of atmos?? Am I right in saying, 10k ppm CO2 = 1% CO2 in atmos.. and 1k ppm O2 = 1% O2 in atmos.... or am I off the mark???

It's a little tricky as the atomic size and occupied space or density of the volume determine %. The % of air at ground level is the same as the top of Everest, but the density of air is much much less. It's about 35% of that at sea level.

Climate crisis scientists tend to ignore relative density being the same % components at both levels

Vertical 0.5 = 50% Atmos 0.1 =10% atmos.... Horizontal axis is Billions of years... Green is best low side and Red is best guess high side... Red feels right

Gotcha - makes sense - so time to apply a bit of common sense to make sense... so might as well harmonise the globe!! to a really really flat flat earth!! with no hills!!! Thus the q for me to make any sense of data is: is CO2 ppm div 10000 to get % atmos at ground level, and Is O2 ppm div 1000 to get % O2 atmos... Anyone have an idea??
