A group of high-profile scientists, economists, and business leaders has called on world governments to launch an Apollo space program–style effort to limit climate change to no more than a 2°C rise in temperature above preindustrial levels through more research into carbon-free energy production. Governments that sign on to the proposed Global Apollo Programme, described in a report released today, would commit to spend at least 0.02% of gross domestic product on energy research so that renewable technologies—principally wind and solar—become cheaper than coal in 10 years.
The report was authored by six members of the U.K. House of Lords, including Astronomer Royal Martin Rees and economist Nicholas Stern, as well as David King, a former U.K. government chief scientific adviser. The effort will require an international commission to avoid duplication of effort and identify bottlenecks in development, the authors note. King told BBC he expects the project to launch in November.
