Hundred-Year Repair

The book's central timeline argument: that the work of solving climate change unfolds across roughly a century, from approximately 2027 through 2130. The Hundred-Year Math refers to the specific arithmetic underlying that timeline. 37 gigatons of annual CO₂ emissions today driven to zero by 2050, followed by removal of approximately 2,000 gigatons of legacy carbon by 2130, financed at scale by roughly $3 trillion per year flowing from the fuel rent dividend.
