A cause of some consternation for almost everyone. Except me, maybe.
You see, I'll all for it.
I grew up and live in a semi-arid region, where the only plants that grow naturally are few and work hard for anything they produce which is never enough to sustain even one person per square mile. So the lack of plant life around me as I grew up is a big influence on how I see what the future might be.
I want plants to grow. Everywhere. All the time.
Right now, they don't. They only grow in certain places. Places that are wet. Riverbanks. Coastlines. Irrigated land.
Ever look at a vegetation map? Notice the vast yellow expanses where nothing is growing? That's a problem. A big problem.
It didn't used to be that way. There was a time when plants grew on the surface in sufficient abundance that it was difficult to find dirt. Plants grew on top of plants. It is called the caboniferous period, and existed about 360 - 300 million years ago. That's when the coal beds were deposited. The plants grew in such abundance that the dead plants were buried before they could decay back into carbon dioxide and water, and became coal. There is a lot of coal below ground, and it all used to be plants.
Here's what I want: to recreate, as best we can, the climate of the carboniferous period:
- Average global temperature: 68 °F. Currently: 56 °F
- Oxygen in the atmosphere: 35%. Currently 21%
- Carbon dioxide levels: 1200 ppm. Currently 410 ppm
Carbon dioxide is the key. We need to put it into the atmosphere, which will let global warming heat the oceans, so water will evaporate and also warm the atmosphere (water is a very good greenhouse gas). Then the plants will grow, and oxygen levels will shoot up. The air will be warmer, so we will be wearing less. And that means we need to lose weight, but that will be easy will an abundance of oxygen to help us work out.
As I see it, global warming is a total win for mankind.
