Aquecimento global

"To achieve the planetary boundary of 350ppm, the global economy needs to be carbon-neutral by mid-century and carbon-negative thereafter. Meeting this target means we all — greens included — need to start thinking like engineers. This is a huge industrial building project, converting the energy basis of civilization from fossil fuels to a variety of cleaner sources. If we do it right, it will not be a burden or a cost to the world's economy, but a source of enormous potential future growth, innovation and job creation."
Mark Lynas, in The God Species
