In between waves of voters I'm reading "After Geoengineering" by Holy Jean Buck, and, holy cow, the author embeds these delightful fiction vignettes in between chapters on the various methods of #CarbonSequestion.
I *love* it. Such a delightful way to break up content. Reminds me of ASU's "City of Light" collection.
@derek@sunbeam.city"But what does the peer-reviewed science say about the potential of #soil #CarbonSequestration approaches? The principles behind soil carbon sequestration are sound and fairly well understood. To grasp its potential, we have to understand the depleted state of soils today. Soils are vast reservoirs of carbon: they hold three times the amount of CO, currently in the atmosphere, or almost four times the amount held in living matter. But over the last 10,000 years, agriculture and land conversion has decreased soil carbon globally by 840 gigatons, and many cultivated soils have lost 50 to 70 percent of their original organic carbon. Intensive crop cultivation can reduce soil carbon by 25 to 50 percent in just thirty to fifty years. The good news is that this can be reversed."
"When it comes to afforestation, #RegenerativeAgriculture, biochar, and blue carbon, #ClimateChange may actually be the least compelling reason to take many of these actions. We should complex forests for their #biodiversity benefits, establish #agroforestry because it increases farmer resilience, recycle crop residues in order to create a #CircularEconomy, improve #farm information systems to help $farmers, and take care of the #soil so as to avoid dead zones in the oceans—and much, much, more. #Climate benefits are a fantastic bonus to these efforts, but the current magnitude of emissions overwhelms what these sinks can address during this century. We are deluding ourselves if we think this can be the only response to the disaster faced by people and species around the world."
"Natural climate solutions should be pursued with all the energy we can muster, and they really can make a contribution. But if we genuinely care about lessening climate impacts, curbing sea level rise, or saving species, other measures will also be needed."
@derek I strongly agree with the doubtful assessment of "this carbon sequestration tech is going to save the world". There's so many other enviro (and other) problems that are highly problematic.
Still am somewhat in awe of the potentials for carbon drawdown, soil repair and improved plant growth via charcoal/biochar.
The historic precedents where its presumed human production of char has led to amazing soils!

P i p @derek yes!! 
I can't stand the climate change deniers who decide that because they think climate change isn't real, no environmental protection and actions should be taken. Absolute excuses! There are so many reasons it's overwhelming
