As we remind ourselves of the historical decision at last year's Climate Summit in Paris, we can keep global warming at 1.5 °C, if we really want it. This year's first Meeting of the Parties to the Paris Agreement (CMA1) in Marrakesh, Morocco, came up with the first practical steps on how to achieve that. Let's not be fooled, more than that is needed. We need serious commitment and action starting with speeding up renewable energies, ocean protection and cleaning up the act of mobility, including the shipping industry.
