The National Research Council has just issued a report that advocates increased research into 'climate engineering', that is, trying to retard global warming through human manipulation of atmospheric processes (1).
The NRC report on climate engineering is both depressing and upsetting. It is depressing because it essentially admits that we are totally failing in our attempts to prevent climate change through reductions in emissions. It is upsetting because it reflects incredible hubris. Do the originators of the report really think that we can meddle with global atmospheric patterns without huge unintended consequences? Haven’t we learned anything about the unpredictability of technology?
To my mind research funds would be far better spent investigating novel ways to restrain the tidal wave of global population growth. That would certainly impact climate change. The much-vaunted ‘demographic transition’ seems to be sputtering as the UN revises its global population projections ever upward.
