We'll probably enter the era of experimental geoengineering pretty soon, I would imagine.

I think at some point in the very near future it would be better off face facts, avoid ag run off and tackle climate change rather than implement more hacks.

I can't help but think all the suggested hacks around climate change are a bad option. We never expected that burning fossil fuels would have such a potentially catastrophic effect on our environment. I imagine that many of the solutions will have similar unintended consequences.

Actually we did expect that. 160-odd years ago, people started to suspect trouble ahead and many decades ago, the writing was clearly on the wall, scientifically speaking.
