well if we're throwing degrees in -- i did an mphil in climate change (by research) while i was at liverpool school of architecture. the thesis set out on the premis that agw was a given and we needed to produce an architecture fit for the impending change. however, my tutor encouraged me to investigate how trustworthy that premis was. to cut a long story short my conclusion was: climate change is happening, whether that be a warming or an eventual cooling i'm not sure, but anthropogenic influence on the climate is almost certain. and my major concern is the belief that technology can save us. during the 70's when an impending ice age was assumed the US congress discussed funding for crushing the Rockies (the mountain range) into dust so that it could be burnt in ovens to release the CO2 to induce GW so that an iceage would be post-poned - thats a very scary use of technology. I think we would all agree that we cannot arrogantly believe AGW can be resolved simply by inventing something or that we as a species have no detremental affect on the planet.
