Over the past century, global emissions of carbon dioxide from the burning of fossil fuels have risen at an average rate of about 4% per year. If emissions continue to increase at this rate, about how much higher will total emissions be in 2057 than they were in 2010? Using the approximate formula, emissions will increase by a factor of between 2010 and 2057. Using the exact formula, emissions will increase by a factor of between 2010 and 2057.
