Follow me through some thought on the matter.
It's 3.5 billion years ago, and I visualize the young Earth, with a somewhat fainter star.
The Earth is very young and it has an atmosphere, without oxygen. This means life as we know it doesn't exist. We would be looking at a barren
planet, without life, there wouldn't be forests that removed carbon from the atmosphere, and without life in the seas, that would photosynthesize
light. The natural way our oceans stock carbon from the atmosphere, isn't functioning yet...
So all carbon, and other gases around, would not be processed into the Earths recycling system yet.
The planet was still very active, it just finished forming after a pretty chaotic start, that caused our planet to get so hot, that it melted again.
So we got a lot of heat, from the interior of the planet, that was probably venting out into the atmosphere, a lot more often, and in unimaginable
large scale events. All released gas, from the period, would stay part of the atmosphere, until life started dumping oxygen in the air, and carbon
would get stocked in the rock, oceans, and soils of the planet, with the death of all living things, every remains of life that, will become stuck
somewhere, is what is responsible for all carbon deposits on Earth.
Then there is the Moon, that was in a much closer orbit. The Moon is still getting further away fom us every year. The tides would be a lot stronger,
and they would pull the water, miles further into land and back. The higher gravity, would also cause much more stress, to the geological structures
at the time, causing it to be more active, producing more quakes and volcanic eruptions, from all the added energy, that is released from higher
gravity of the Moon, on the Earths crust.
So we got a number of reasons for higher readings of carbon in the atmosphere. More geological activity, and a much hotter interior of the planet,
that can all cause more heat, stay trapped in the early atmosphere.
So... What do you think ?
There should be a math guy, who can calculate the separate effects, and the amount of heat that would add, into our atmosphere.
Eventually the balance was right, we are living proof of that.
