Engineering Earth ‘is feasible’

Wind-powered yacht (J. McNeill)A UK Royal Society study has concluded that many engineering proposals to reduce the impact of climate change are “technically possible”.

Such approaches could be effective, the authors said in their report.

But they also stressed that the potential of geo-engineering should not divert governments away from their efforts to reduce carbon emissions.

Suggestions range from having giant mirrors in space to erecting giant CO2 scrubbers that would “clean” the air.

Such engineering projects could either remove carbon dioxide or reflect the Sun’s rays away from the planet. …

The study stressed that engineering approaches would only have a limited impact, and that efforts should continue to be focused on reducing CO2 emissions.

“(Governments) should make increased efforts toward mitigating and adapting to climate change and in particular agreeing to global emissions reductions of at least 50% on 1990 levels by 2050 and more thereafter,” the authors wrote.

But, they continued, there should be “further research and development” into geo-engineering options “to investigate whether low-risk methods can be made available if it becomes necessary to reduce the rate of warming this century”.
