Geoengineering won't curb sea-level rise : Nature News
[Richard Alley, a glaciologist and climate researcher at Pennsylvania State University] "We don't really have an ice-sheet model that we trust," says Alley, noting that, in addition to global warming, glaciers react to local and regional changes in winds, ocean temperatures and ocean circulation. "In many ways," he says, "this large advance serves to show how far we have to go before climate modelling of geoengineering is really good enough that useful regional projections could be made to guide decision-makers."
