Some solutions and challenges listed.
Our opening battles in the war on climate change need engineers to work on the many existing technologies that can massively scale up. As already illustrated with wind, solar, and batteries, such scale-ups often bring dramatic drops in costs. Other industrial sectors require technological revolutions to reduce emissions. If you experiment with your own mix of climate-mitigation techniques using the En-ROADS interactive climate tool, you’ll see how many options you have to max out to change our current trajectory and achieve 350 ppm CO2 levels and a global temperature rise of no more than 1.5 °C.
