Carbon dioxide (CO2) levels in the atmosphere have risen 35% faster than expected since 2000, says a study.International scientists found that inefficiency in the use of fossil fuels increased levels of CO2 by 17%.
The other 18% came from a decline in the natural ability of land and oceans to soak up CO2 from the atmosphere.
About half of emissions from human activity are absorbed by natural "sinks" but the efficiency of these sinks has fallen, the study suggests.
