Geoengineering is getting more and more attention in political discussions as well as research. I am by no means a proponent of any geoengineering scheme I have heard of and the majority of them try to address surface temperature only and therefore do nothing about "the other CO2 problem", aka ocean acidification. I must confess that H. E. Taylor's article a while back went some way in convincing me that like it or not we need to be considering these perilous pathways. He basically makes the compelling argument that we are in fact now, unwittingly or not, geoengineering our global climate…
Don't miss April 19th's APOD, a truly awsome sight! And while on the subject of Eyjafjallajokull and my recent post about it, readers should be aware of a correction on the source site. The best estimate of CO2 is in fact 150,000 tons per day, not 7400, with a possible maximum of 300,000 tons per day. So the graphic is much less compelling, but the story of Joe vs the Volcano is not affected.
