In the absence of significant greenhouse gas (GHG) mitigation, many analysts project that atmospheric concentrations of species identified for control in the Kyoto protocol could exceed 1000 ppm (carbon-dioxide-equivalent) by 2100 from the current levels of about 435 ppm. This could lead to...

This study examines the paradox that the path of realized global warming by a given year is linear in cumulative emissions of carbon dioxide even though the corresponding eventual equilibrium warming is only logarithmic in atmospheric concentration. It then provides parameters for this linear...
