Global carbon emissions rising rapidly - study

SINGAPORE (Reuters) - Global carbon emissions rose rapidly in 2007, an annual study says, with developing nations such as China and India now producing more than half of mankind's output of carbon dioxide, the main gas blamed for global warming.

The Global Carbon Project said in its report carbon dioxide emissions from mankind are growing about four times faster since 2000 than during the 1990s, despite efforts by a number of nations to rein in emissions under the Kyoto Protocol.
