In order to ensure that the climate does not flip to a situation where human life would be drastically reduced, we need to keep warming under 2 degrees. To do that we need to restrict release of climate gasses into the air. Stopping the burgeoning of fossil fuels is one major part of that. But there is some wiggle room, we could maybe burn a little more……. The question is, what are we going to burn it doing?
If you ask me, ( a few do), I would say we need to use it to create sustainable communities that are far less dependent on transportation of goods to and from them. These communities need to have their own renewable sources of energy, and be designed so food and fiber production is carried out close by without the need to burn fossil fuel.
The diagram below explains how much is left. Anyone got a detailed idea of what we could do with it?
