Some media rank climate engineering as an important news event of 2012.
UnderwaterTimes.com: Geo-Engineering Against Climate Change: Seeding The Oceans With Iron May Not Address Carbon Emissions
„Previous estimates of cost fail to recognize the economic challenge of distributing low concentrations of iron over large areas of the ocean surface and the subsequent loss processes that result in only a small net storage of carbon per square kilometer fertilized.“

„This paper argues that there is an urgent need for the international community to establish a governance framework to control geoengineering experimentation and implementation. All proposals currently under discussion are likely to have some adverse, possibly severe, impacts on ecosystems or climate“

„One idea, touted by permaculturist Mark Shepard, is to change the farming paradigm away from annual crops to perennial crops.[nbsp] The concept of replanting crops every year is the norm in farming culture, but we don’t often stop to ask if that is the most efficient and environmentally friendly methodology.“
The article discusses mitigation and adaptation against CE.
