Uncertainties related to the impact of human activities on climate will decline

An international study, involving French climate scientists, shows that the CO2 contribution to climate disturbance from human activities is increasing, leading in 2030 to a 50% uncertainty in climate sensitivity to these disturbances. It is published online by Nature Geoscience, February 23, 2015.

Current models of climate evolution indicate a global warming due to the greenhouse effect caused by increasing amounts of CO2 into the atmosphere partially offset by cooling due to the presence of paticles. Both CO2 and particles are being emitted by human activities.
