Top science body calls for geoengineering 'plan B'

Take note: the back-up plan for saving the world is no joke. A major scientific institution has published a comprehensive review of possible ways to engineer the climate to reverse global warming.

The UK Royal Society’s review of geoengineering will make it difficult for governments to ignore the issue. It says that while reducing emissions of greenhouse gases “absolutely” must remain a priority, there is a serious chance that this will not be enough to stave off global warming of 2

“My guess would be that there is a 50-50 chance that we can achieve something with emissions reductions,” says John Shepherd of the University of Southampton in the UK, chair of the Royal Society group behind the report.

If humanity wants to avoid the worst effects of climate change, it must be ready to safely deploy geoengineering methods as and when necessary, the report says. “We are already staring 1.6
