Book excerpt: The Paris Accords, widely accepted as the key to solving today's climate crisis, set a goal of zero net carbon emissions by 2050. But that's not good enough. The only way to guarantee a livable future is climate restoration, which can reduce greenhouse gases to historic levels. Scientist and entrepreneur Peter Fiekowsky explains the technology and maps a practical path that will let humankind survive and thrive.As Fiekowsky explains in Climate Restoration, this will require removing a trillion tons of excess CO2 from the atmosphere. The good news is that this task, while enormous and technically challenging, is eminently feasible. Scientists and engineers have developed four major technologies for greenhouse gas removal and storage: Ocean iron fertilization; synthetic limestone manufacture; seaweed permaculture; and methane oxidation.Fiekowsky shows that these technologies are safe and practical-and, even more remarkable, that they require little if any government funding, since they can be financed largely through existing markets. For these reasons, they have enormous promise as vehicles for achieving climate restoration.With the global climate crisis continuing to spiral out of control, the time for tough conversations about what it will really take to create a healthy future for humanity is here. Climate Restoration will inspire those conversations and, ultimately, the actions we must take to ensure a livable planet for generations to come.
