A professor from Concordia University's Department of Geography, Planning and Environment, along with colleagues from Victoria and the U.K. have found a direct relationship between carbon dioxide (CO2) emissions and global warming.
The team, lead by Damon Matthews, used a combination of global climate models and historical climate data to show that there is a simple linear relationship between total cumulative emissions and global temperature change, according to the Concordia University press release.
Matthews and his colleagues show that each emission of carbon dioxide results in the same global temperature increase, regardless of when or over what period of time the emission occurs.
For every tonne of CO2 that is emitted there will be an increase of 0.0000000000015 degrees of global temperature change.

According to the study, we must restrict total carbon emissions, from now until forever, to little more than half a trillion tonnes of carbon, or about as much again as we have emitted since the beginning of the industrial revolution.
