Renewable energy is not replacing fossil fuels as quickly as scientists forecast — leading to a serious underestimation of what still needs to be done to stabilize the world's climate, according to a new analysis.
"Enormous advances in energy technology will be needed to stabilize atmospheric carbon-dioxide concentrations at acceptable levels," said Roger Pielke Jr. of the University of Colorado at Boulder and his colleagues, writing in today's edition of Nature.
The United Nations Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Peace Prize with former Vice President Al Gore, expected that people around the world would be using more renewable energy, reducing global dependence on the fossil fuels
Those gases trap the sun's heat in the atmosphere and have been linked to rising global temperatures.
Instead, people are using more oil, gas and coal than ever before, pumping more carbon dioxide and other greenhouse gases into the atmosphere, said Tom Wigley, a scientist with the National Center for Atmospheric Research in Boulder and a co-author of the Nature article. more...
