The world needs to employ lower-carbon energy sources such as renewables and natural gas to break dependence on fossil fuels and limit temperature increases, says the Intergovernmental Panel on Climate Change in its latest report. Separately, developing countries need assistance to help them develop economies powered by sustainable, less carbon-intensive technologies, aid groups say.
France's desire to withdraw troops from Mali is being thwarted by a rise in rebel insurgents, writes John Irish. "A sporadic insurgency coupled with a slow process in negotiating with disenfranchised Tuareg separatists in the north, who have vowed to remain armed until they have certain guarantees, may also scupper [French President Francois] Hollande's plans," Irish argues.
Negotiators at the UN climate talks in Mexico are trying to break the gridlock over agreement by extending the responsibility for cutting greenhouse gases to developing countries. Currently only wealthy countries must curb carbon emissions from 2008 to 2012.
Governments are investing in rail as a less carbon-intensive transportation method, with development and advertising campaigns emphasizing rail as a greener -- and faster -- choice. China is investing heavily in a nationwide high-speed rail network. Europe likely will boast faster point-to-point travel by rail than by air over certain routes by 2020.
Although India has said until recently that developed nations must bear the brunt of carbon-emissions cuts to prevent catastrophic climate change, recent pledges from the U.S. and China to cut carbon emissions and reduce carbon intensity have inspired India to follow suit -- or at least put pressure on India to comply. The government might announce a new carbon-intensity target, which would reduce the amount of carbon emissions relative to India's economy.
