Well, nobody said there's rule that says reality has to align with how we would like things to be.
The problem is greater than that. I urge you to read the paper and look at the data. We are talking about planetary scale issues here, which means solving the problem in 50 or 100 years by forcing it (chemically or whatever) is far more likely to kill all life on this planet than to fix anything at all.
And, so, sadly, 100% renewable --which is impossible-- and reforestation will not do it either.
First of all, aside from the fact that 100% renewable --again, global, planetary scale-- is impossible, we already know that, if we did that, atmospheric CO2 levels would continue to rise exponentially. That's the paper I linked to in my comment.
That leaves reforestation. So, we start with atmospheric CO2 continuing to rise exponentially and want trees to fix it.
Here's the other dose of reality, which comes from a simple question:
How did the planet "fix it" on its own when we were not around?
Simple:
- Trees grew
- Storms, cyclones, hurricanes, rain
And it took 50,000 to 100,000 years for that to drop atmospheric CO2 by 100 ppm. Again, please, don't take my word for it, I'm just another delusional moron, go look at the data and challenge that. I'd be very interested in learning I am wrong and how.
The other question is:
How did the planet cause CO2 levels to rise?
Simple:
- Massive continental scale fires burning for tens of thousands of years
Look at what's going on in Australia. Even with all of our technology we can't stop it. I have no idea how much CO2 got injected into the atmosphere so far but it can't be trivial. Now imagine that at a global scale, with massive country and continent scale fires raging unimpeded. That's how the planet did it.
Which brings me back to the reforestation issue. Yes, we need to restore the Amazon and other areas. What we've done is criminal. However, we are not going to fix the problem in 100 years by doing this. We can't.
The other danger is, once again, fires. If we plant trees on every available square meter --assuming that was possible-- we would be creating massive amounts of fuel for fires much larger than what we are seeing in Australia. In other words, just planting trees isn't a solution at all, and doing it without an understanding of the dangers involved could kill more life on earth than the alternatives.
It's a very difficult problem. I don't claim to have any solution. All I know is that we are not discussing the truth. All we have are two religious camps, one saying it isn't real and the other saying we have to destroy entire economies to fix it in 50 years. Both are crazy.
