As the world continues to struggle with the effects of climate change, energy transition is more important than ever as a key pathway to stopping global warming. But will it be enough? Many serious climate researchers think it won’t be, and urge deliberate attempts to directly alter the Earth’s climate by using a number of technologies, loosely grouped under the heading of geoengineering. But geoengineering has not won much support from the climate and environmental communities, and still struggles to gain enough legitimacy to attract sufficient research funding to attempt serious pilot projects that might tell us whether geoengineering holds real promise as a safe, cost-effective, and powerful tool in a portfolio of climate change mitigation strategies.
So what is the real potential of geoengineering to address climate change? How much would it cost? How risky is it, and what justification might there be for taking that risk? And what sorts of attitudinal shifts might be needed within the climate and environmental communities to embrace geoengineering as one of a portfolio of strategies? We attempt to answer all of those questions and more in this interview with a veteran science journalist and author of a recent book on geoengineering.
