Study says carbon dioxide levels rising faster than anticipated
The concentration of carbon dioxide (CO2) in the atmosphere is increasing faster than expected, according to a new study published in Tuesday's edition of the Proceedings of the National Academy of Sciences. The study said that rising levels of CO2, the main greenhouse gas blamed for climate change, threaten to accelerate global warming. The study attributes the change in CO2 levels to increased use of fossil fuels and a decline in the amount of gas being absorbed by the oceans and land. CO2 emissions have increased by an average of 3.3 perc
