The late Sherwood Rowland, Nobel Laureate, said upon accepting the prize:
"What's the use of having developed a science well enough to make predictions if, in the end, all we're willing to do is stand around and wait for them to come true?"
This is a question I would like to ask every scientist who is doing research that proves tropospheric ozone is damaging trees and crops. They prove it over and over again! Of course, the same could be said for climate.
This interview with David Wasdell dates from 2007. He explained back then, in the most genial and pleasant fashion, that climate predictions forged through political consensus in the IPCC process weren't nearly as dangerous as reality - and that it was urgent that we stop emitting greenhouse gases before tipping points put earth on track for runaway warming.
