Carbon negative solutions are the only way we can honestly address the integrated and hard challenges posed by the synergy of:  1] Climate disruption; 2] Ocean warming; & 3] Ocean acidification.  All of these problems are driven by too high levels of CO2 in the atmosphere.  Simply reducing the rate at which we add to this existing problem is no solution at all.   After all, if I am a sinner, but now I sin less, I am still a sinner.

The only long term solution requires us to reduce the amount of CO2 in the atmosphere.

This strongly suggests that the Clean Stoves project of the Global Alliance take a broader look at the benefits derived from stoves based on pyrolysis, rather than combustion,  that yield biochar for long term carbon sequestration with substantial other benefits.

If you are not familiar with Ocean Acidification, google will give you many results to follow up on.  Scientific American has been following the ocean acidification problem since at least 2006.  This guide for policy makers is informative and useful.
