New climate model says 2° target not out of reach if….

The Hamburg scientists say there is a direct connection between the melting of the Arctic sea ice and global warming

Scientists from the  Hamburg-based Max-Planck-Institute of  Meteorology and the German Climate Computing Centre have calculated that the 2° limit for global warming could still be kept to. However, it would require immediate drastic reductions in carbon dioxide emissions.  So what’s new? I hear you say. The new element is the model the scientists are using. The  new model developed by the Max-Planck-Institute using the high-powered computer capacity of the Hamburg centre integrates additional factors into its simulations for the 21st century, including the complex carbon cycle and dynamic role of vegetation, and compares numerous climate models from around the world with each other.The simulations indicate that if the CO2 concentration continues to rise as it is doing, we will be facing not only a considerable rise in temperature, but also an increase in the speed of ocean acidification.
