Question

Atmospheric CO2 concentration by the year 2100 will be 476, and the average temperature increase over preindustrial levels will be 2.5 degrees celsius. If all things remain the same except we stop increasing the input of CO2 to the atmosphere now (year 2016), atmospheric CO2 concentration will be 464 ppm by the year 2100. The average temperature increase compared with preindustrial levels will be 2.3 degrees celsius.
