"At last—a global plan that actually adds up."—James Hansen, former director, NASA Goddard Institute for Space Studies The world must reach negative greenhouse gas emissions by 2050 to avoid the most catastrophic effects of climate change. Yet no single plan has addressed the full scope of the problem—until now. In The 100% Solution, Solomon Goldstein-Rose—a leading millennial climate activist and a former Massachusetts state representative—makes clear what needs to happen to hit the 2050 target: the manufacturing booms we must spur, the moonshot projects we must fund, the amount of CO2 we'll have to sequester from the atmosphere, and much more. Most importantly, he shows us the more prosperous and equitable world we can build by uniting the efforts of activists, industries, governments, scientists, and voters to get the job done. This is the guide we've been waiting for. As calls for a WWII-scale mobilization intensify—especially among youth activists—this fully illustrated, action-oriented book arms us with specific demands, sets the stakes for what our leaders must achieve, and proves that with this level of comprehensive thinking we can still take back our future.
