Cirrus clouds might not be playing the positive feedback role in global warming that most scientists assumed. (Less of them around may mean a welcome negative feedback.) Possible good news gets the smallest of media attention, though.
Meanwhile, Planktos wants to try more ocean iron fertilization, but are getting threats from environmentalists and criticism from many others.
I don't know, seems to me to be rather hypocritical to be both in a panic about global warming and also oppose full assessment of possible alleviation measures.
