The world’s climate could be hijacked by a rogue country or wealthy individual firing small particles into the stratosphere, claims a warning that comes not from a new Hollywood movie trailer but a sober report from the World Economic Forum (WEF).
The deployment of independent, large-scale “geoengineering” techniques aimed at averting dangerous warming warrants more research because it could lead to an international crisis with unpredictable costs to agriculture, infrastructure and global stability, said the Geneva-based WEF in its annual Global Risks report before the Davos economic summit later this month. It also warned that ongoing economic weakness is sapping the ability of governments to tackle the growing threat of climate change.
“The global climate could, in effect, be hijacked. For example, an island state threatened with rising sea levels may decide they have nothing to lose, or a well-funded individual with good intentions may take matters into their own hands,” the report notes. It said there are “signs that this is already starting to occur”, highlighting the case of a story broken by the Guardian involving the dumping of 100 tonnes of iron sulphate off the Canadian coast in 2012, in a bid to spawn plankton and capture carbon.
