Abstract
There are three emerging areas of research that we believe hold promise for helping to understand and mitigate the impacts of climate change. Although they stem from diverse fields of inquiry, we believe their effects are tightly coupled. These concern the following: (1) the role of soils in climate stability and their potential for significant, permanent, and viable carbon sequestration of up to 10 gigatons per year, (2) the role of ocean anoxia as a predecessor to extinction episodes, and its troubling rise in today's seas, and (3) the role of algae eating fish, such as menhaden, in controlling estuary eutrophication and rapid expanse of ocean "dead zones". Seen together, these three areas of research show that restoring degraded soils while putting a moratorium on the fishing of algae eaters, may in fact be the most efficient way to reduce atmospheric CO2 to below dangerous levels (350 ppm) while avoiding perilous trigger events, such as ocean anoxia. These measures can be achieved without great sacrifice or cost, and in a fashion that supports improved yields, reduced environmental impacts, and new sustainable economies.
