Did god create man-kind to produce CO2 and save the earth?

As a non-believer, this is a strange post, however since I realised that the Carboniferous period nearly saw the first collapse of life on earth – and we were only saved by dry rot fungus – I’ve realised the earth was heading toward another calamity before humanity came along and (for the meantime) to save planet earth.
But first some basic biology. Plant need CO2 to grow. And without CO2 there would be no plants, and without plants there would be no animals, and without animals or plants there would be none of us humans.

So, lets review the evidence of CO2 over geological time. Above is a graph showing CO2 and temperature. As you can see there is no correlation between temperature. However what we also see are two very distinct minimums of CO2 level. The first occurred around 350million years when it is thought that plants evolved that produced Lignin. This is a hard material, and whilst it allowed plant to grow much taller and resist attack by fungi, but it had the huge problem, that it was so resistive that plant material was not decomposed by the then fungi. The result was that plant material started to pile up, forming huge geological deposits we call “Coal”. The problem as we can see is that all this plant material locked up carbon and prevented it being turned into CO2. And as a result CO2 levels – the essential plant food of life – collapsed.
Then around 250million years ago, it appears that “dry rot” fungi developed that had evolved a means to decompose lignin. This massively boosted CO2 levels –  we then go into the age of dinosaurs.
However, from around 180million years ago, we start seeing the second collapse of CO2 until around 20million years ago we reach the second CO2 desert period. That didn’t look to be a problem until I started looking at ice-cores.
If you’ve studied climate, you will be familiar with the ice-age cycle:

The plot above shows the regular “heartbeat” of the ice-age cycle which we tend to think as “normal”. However, if we look at a measure giving us a longer view, the current 100,000 year cycle is far from normal. Before the current 100,000 year there was a period of around 1million years with around 40,000 year cycle, and before an even shorter/more irregular cycle.
Indeed, what seems to be happening is that the “heartbeat” of the ice-ages is slowing down. The interglacials such as we live in now, are in the overall scheme of things pretty short periods. And one seems to happen is that there is a rapid period of warming causing the world to come out of glaciation – that period last a few 10s of thousands of years – and then the planet slowly sinks back down in the dry cold period of glaciation.

Could the CO2 desert be causing current glaciation

So, far no one has come up with a clear understanding of how the glaciation cycle works. And although I’ve previously suggested a few mechanisms, from CO2 triggering plant grow – which then leads to more water vapour (a powerful greenhouse gas) to gas release from volcanoes directly heating the earth through increased air pressure, I’m yet to be convinced I’ve found the answer.
However, it does seem possible that the reason we have entered this glaciation period is a result of the “CO2 desert” conditions the world is currently experiencing. Indeed, if you believed the global warming alarmism – you would have to believe the drop in CO2 was causing the cooling.
And so if you were an alarmist – you would have to believe that all that CO2 being tied up in geological processes was gradually killing the world.
For it does seem that the world’s “heartbeat” has been slowing and if the 100,000 year cycle were to have lasted just over 1millino years as the 40,000 year cycle did before, then we were not short off what could have been the last “heartbeat” before the earth was forever held in the icy grip of a perpetual ice-age. One which would only get worse and worse as more and more CO2 were tied up until we had a snow-ball earth devoid of life.

God

So, if I were religious – it would look to me that “God had created man-kind to save the world”. That is to say – the whole intention of “God” would appear to have been to create human civilisation to unlock all the CO2 that had been caught up in carboniferous coal deposits and thereby keep this wonderful planet going for a few 100million years more.
