Now we have more information on a cooling factor (tip to Instapundit):
According to a study by the Institute of Catalysis and Environment in Lyon (IRCELYON, CNRS / University Lyon 1) and the Leibniz Institute for Tropospheric Research (TROPOS), the oceans are producing unexpectedly large quantities of isoprene – a volatile organic compound (VOC) – which is known to have a cooling effect on climate. ...

Just remember, it's only a model.
