Computer models show geoengineering schemes would be futile to prevent climate change. Researchers from the Helmholtz Centre for Ocean Research Kiel, Germany, say the most that could be expected is a temperature drop of 8%. But that’s not the half of it; the potential side effects would be potentially disastrous. Two of the five methods considered could not be safely stopped, say scientists. Two methods could be stopped if the irrigation needed to grow the trees were stopped, they say. CO2 mitigation seems to be the most effective way to stop climate change, say researchers.”]
