The Great Debate UK
Ahead of a U.N. summit in Copenhagen next month, scepticism is growing that an agreement will be reached on a global climate treaty to replace the Kyoto Protocol, due to expire in 2012.
The protocol set targets aimed at reducing greenhouse gas emissions, which are believed to be responsible for the gradual rise in the Earth’s average temperature. Many scientists say that reducing carbon dioxide emissions is key to preventing climate change.
“If the goal is to stop warming then geo-engineering solutions are worth considering because they are far cheaper, probably much more do-able and easily reversible,” Dubner told Reuters before a talk at the Royal Society for the encouragement of Arts, Manufactures and Commerce in London.
