Researchers: carbon dioxide emissions hit record in 2011
The New York Times reported that global emissions of carbon dioxide (CO2, the most significant heat-trapping gas in the atmosphere) were at a record level in 2011. Researchers believe the global emissions of carbon dioxide are likely to hit record again in 2012, because efforts to limit emissions seem to be failing.
Due to continued increase of global emissions, the objective of limiting global warming is difficult to achieve.
