Dear all, Altho I have great respect for John Holdren, there are two issues where we have different opinions. First, he has failed to realize what an enormous technology challenge we face to keep CO2 at an acceptable level through mitigation. Second, he leans towards being against geoengineering.
Alvia gave us the following quote ... > The ‘geo-engineering’ approaches considered so far appear to be afflicted with some combination of high costs, low leverage, and a high likelihood of serious side effects.” In my view, this is wrong in the combined mitigation/geoeng case that I espouse.
