The Carbon cycle

Go back two hundred years

The carbon cycle has been occurring for four billion years.  Plants take carbon from the air and store it in themselves. When the plants die the carbon is either composted or trapped underground to become coal. Animals take carbon from plants and become oil in death.

As a result the level of carbon dioxide is the air has been steadily decreasing since life started to flourish.

Present day

We are putting all the carbon back in the air.

Perhaps a good way to explain the complex phenomenon of global warming is just to say we are turning back the clock, rapidly. The earth will find it’s equilibrium again but it might be a bumpy ride.
