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.
2012 was the second wettest year on record in the UK and the wettest ever in England, the Met Office announced on Thursday.
As Lisa Jackson gets ready to step down as head of the EPA shortly after the president's inauguration later this month, she is being hailed by environmentalists for pushing through the toughest new air and water pollution rules in over two decades, and speaking out on climate change in an administration that has largely avoided confronting the issue head-on.
Fresh water is crucial to human society – not just for drinking, but also for farming, washing and many other activities. It is expected to become increasingly scarce in the future, and this is partly due to climate change.
China and the US are to be the clear focus of the next year of climate change negotiations, following a hard-fought climate conference that ended in Doha on Saturday night.
