Global emissions of carbon dioxide from fossil-fuel burning jumped dramatically over the past year, making it unlikely that global warming can be limited to 2 degrees by 2020, which was an international goal set by the Copenhagen Accord in 2009. The National Oceanic and Atmospheric Administration (NOAA) has recorded a CO2 jump by 2.67 parts per million since 2011 which is the second highest greenhouse emissions rise since 1959, when the agency started measuring carbon levels.
