Using emissions data from 2004 and 2006, they determined that commercial aircraft emissions were responsible for eight percent of total surface warming since records began in 1850. The situation in the Arctic is more extreme. Research showed that between 15 to 20 percent of warming in this region was caused by commercial aircraft.
