Interesting thing is, they make no mention of reforestation. That is part of what went wrong to begin with. Still taking place in places across the planet. I can't count the number of times I've seen houses on streets with nary a tree in sight.
To me it is just so obvious that there is supposed to be a layer of canopy that shields the soil from the harsh sunlight so that water won't evaporate and dry up all the living carbon protected by it.
Humans who only see the value of clearing away that canopy and replacing it with buildings/pavement/infrastructure are missing the function of a living layer of carbon-absorbing organic material and its sediments.
It would be so easy to restore climate if we would just give the soil back to tree roots and the fungi and other soil flora that sustain them and clean groundwater as it filters down into aquifers.
The Earth has a natural carbon cycle that sucks carbon out of atmospheric CO2, deposits it in living organisms, and then gradually condenses their sediments underground.
We want to dig it all up, burn it to extract the energy, and then suck it back out of the atmosphere artificially, which will obstruct the long process of restoring fossil fuel deposits so future generations will inherit the same natural resources that pre-industrial humans did.
We never think about how something artificial will age and eventually break down into junk. We fail to value nature's amazing capacity to heal and regenerate into a renewed/rejuvenated state. Human-made systems wear out and have to be rebuilt by humans, but natural ecosystems simply decompose their own detritus and turn it into fertilizer for the next generation using nothing but water, sunlight, and amazingly complex DNA processes that make all the enzymes necessary to do the work at the nano-scale.
It's so ironic that humans are fascinated by nano-engineering, yet most fail to appreciate how nature nano-engineers a totally sustainable biosphere in the absence of human effort and/or digging up and burning fossil fuels for power.
