"One of the key primary reasons against geoengineering is seen as the risk associated with tinkering with the atmosphere for fear of creating unexpected side effects. The argument goes like this: the coupled atmosphere ocean system is highly complex. Therefore, it is impossible to attempt to alter one facet of the system to combat climate change without inadvertently disrupting some other part of the system."

"Wherever you stand on geoengineering — whether you think it’s our only chance of survival or a fast track to extinction — we should at least consider the idea. As I argued last year, just studying geoengineering could teach us a lot about the climate and just talking about it could ease some lingering political tensions around climate change."

"Geoengineering has fomented plenty of controversy as a means of avoiding the risks of climate change. As the argument goes, long-term plans to mitigate climate change, such as the agreement reached at the COP21 talks in Paris last month, cannot happen fast enough to prevent this global warming car-crash from occurring."

"It’s not about implementing a scheme to cool the planet tomorrow—it’s about giving future generations the information they need to make a smart choice."
