Q I still haven’t had explained to me how the seasonal variations in CO2 concentration create the seasons.
A Well, first of all you have to forget all that stuff about the spinning Earth being tilted at an angle of twenty-something degrees to the ecliptic, and cooling during its Northern winters, warming during its summers. Forget about the Sun. Or better still, think of the Earth as being flat.
Think instead about CO2 in the atmosphere. During summer, when plant photosynthesis is maximum, plants absorb CO2 from the atmosphere, and reduce its levels, and thus reduce global warming, resulting in a subsequent cold winter. During winter, when plant photosynthesis is at a minimum, CO2 levels tend to rise, resulting in global warming - and the subsequent warm summer.
See. Quite easy to explain.
You’ll probably want to know about anthropogenic seasonal variation too. That is, how humans manage to create the seasons. And this happens because, during winter, humans tend to light fires to keep warm, and these fires generate CO2, which causes global warming, and results in warm summers. During these warm summers, humans stop burning fires, and the excess CO2 is absorbed by plants, reducing atmospheric CO2 concentrations, and bringing global cooling, and the subsequent winter.
The result, as I’m sure you’ll see, is that the seasonal cycle of spring-summer-autumn-winter is entirely created by human activity, and if humans would simply stop burning fires in winter, this seasonal variation would vanish, and terrestrial surface temperatures would remain more or less constant.
Convinced? I’m sure you are. If you want to save the world from the endless cycle of the destruction of the creation, all you have to do is to not turn on your heating system when temperatures fall 10 or 20 degrees C below zero. It would also help if you stayed outside, and didn’t wear any clothes, or ate anything. You know by now that it makes no sense to do stupid things like that, right?
LOL
Save the planet; stop exhaling.
