Earth’s climate is out of balance: the planet has been warming since industrialization began, because CO2 increasingly collects in the atmosphere. Even an immediate stop of all emissions would not bring global warming to a sudden halt, reveals a study by Thorsten Mauritsen, Research Group Leader at the Hamburg-based Max Planck Institute for Meteorology, and his colleague Robert Pincus, a scientist at the University of Colorado in the US: in this case, in addition to previous warming of 0.8 degrees Celsius, another 0.3 degrees Celsius would be added by the end of this century alone.
