A FLASHBACK ARTICLE
Artificial clouds to reflect away sunlight, creating colossal blooms of oceanic algae and the global use of synthetic carbon-neutral transport fuels are just three of the climate transforming technologies in need of urgent investigation, according to leading scientists. The eminent group argue that, with governments failing to grasp the urgent need for measures to combat dangerous climate change, radical – and possibly dangerous – solutions must now be seriously considered.
The idea of engineering on a planetary scale in a bid to control climate has been around for more than 50 years but, to date, has remained on the fringes. The potential for dramatic and beneficial change has hitherto been outweighed by the risk of unexpected side-effects in the complex climate system, with global consequences. Now, in a special edition of the journal Philosophical Transactions of the Royal Society, climate scientists and engineers have brought together the latest research and issued a call for a far-reaching assessment of a raft of geo-engineering techniques.
