Any attempts to engineer the climate are likely to result in "different" climate change, rather than its elimination, new results suggest. Prof Ken Caldeira, of Stanford University, presented research at a major conference on the climate risks and impacts of geoengineering. These techniques have been hailed by some as a quick fix for climate change.

But the impacts of geoengineering on oceans, the water cycle and land environments are hotly debated. They have been discussed at a meeting this week of 12,000 scientists in Vienna. Researchers are familiar with the global cooling effects of volcanic eruptions, seen both historically and even back into the deep past of the rock record. With this in mind, some here at the European Geosciences Union General Assembly ( http://www.egu2015.eu ) have been discussing the possible worldwide consequences of pumping sulphate aerosols into the stratosphere to attempt to reflect sunlight back into space and cool the planet.

    I suppose I do have something to add after all. We create a lot of CO2 because that is a consequence of activities which are core parts of our societies. Any consideration of cost and benefit is completely absence from the superficial observation that paleoclimate data is "not perfect". Rather, we should be asking is it good enough, especially with the built-in bias to exaggerate the effects of anthropogenic global warming, to make global policy decisions on that affect everyone? No, it isn't.
