Can carbon capture and storage save the climate from the consequences of fossil fuel burning? This in-depth report from Scientific American surveys global efforts to eliminate climate impacts from power generation. Without such technology, it will be extremely difficult for the world's largest emitters—China, U.S., the European Union and India—to combat climate change and produce the energy to power the global economy. As an environmental journalist since 1999, I have been covering climate change for a decade now. From the failures of previous negotiations, I have witnessed firsthand the critical role technology will play in solving the problem of excess greenhouse gas emissions as well as making climate change politically possible to solve.
