From sucking carbon straight out of the air, to geoengineering our atmosphere to physically block out sunlight, to planting more than a trillion trees, the options may seem futuristic or tough to implement.

But as time runs out on conventional solutions to climate change, scientists are asking the hard questions: Can new, sometimes controversial, solutions really work? And at what cost?
