Warning: I am not a climate scientist. However, I have to disagree that humanity has to leave the planet, or that it's impossible to fix. I will agree that it's very unlikely to be fixed or mitigated to a decent amount before disaster happens, but that's because of politics and human stupidity, not because it's not possible. More CO2 in the atmosphere doesn't have to equal higher average global temperatures. CO2 hold…
In the article mentioned by parent comment, they suggest extracting CO2 from atmosphere and storing it somewhere safe. There is (at time of article's writing) no technology capable of doing so. I guess it is would be "safer" than creating a "solar shade"? I am not a climate scientist either..
How much energy will this require?
How will we generate it?
Will generating that energy produce CO2 or other problems?
What resources are we going to need (chemicals, etc.)?
How are we going to extract or produce them?
How much energy is that going to require?
How are we going to produce that energy?
Will generating that energy produce CO2 or other problems?
Conservation of Energy is an ass. It does not care one bit. Which means we can't solve a problem with less energy than what went into creating it in the first place.A common misconception is that humanity added a bunch of CO2 in a couple of hundred years. That's not true. It took millions, if not billions of years. Sure, in therms of use using petroleum, yeah, we did it in a couple of centuries. However, the reality of this fuel is that it took billions of years to create. THAT is what we burned; billions of years of stored energy.
That was the other revelation I had during my research. We are looking at this with the wrong time scale. In a couple of hundred years we burned millions or billions of years worth of stored energy. And to clean-up that mess you need far more energy than what it took to produce the mess in the first place.
Imagine how many trees, plants, animals and solar energy went into creating the petroleum we burned. That's the start of the scale of the problem we are trying to fix. In other words, we can't fix it. Not without making a much larger mess.
