How best to chill a hot planet?
A blog post by Wired’s Alexis Madrigal does a great job explaining the results from a new paper by a pair of environmental scientists ranking the geoengineering options for cooling the planet in terms of how much cooling they can do.
My discussions with Ken Caldeira on this make it clear that these are plan B or plan C- they are not what we should be doing now. But the more we delay, the more we may leave ourselves with no other choices.
And if we humans really are in charge of managing global climate, we are going to need some of these tools!
