Climate change is ongoing. Both insidious changes such as sea level rise or vector migration and the increase of extreme events in their frequency as well as their intensity are evident. Extensive detrimental impacts and related costs will occur in the targeted +1.5°C World and even more so if we get to +2°C above pre-industrial levels. It is all but sure that we will be able to meet this “Paris agreement” at all. Global greenhouse gas emissions are higher than ever and they increase further. There are first indications of the onsets of several irreversible subsystem changes that may both individually or in cascades cause positive feedbacks leaving us without any further chance to counteract. There is still a small window open for action, yet it requires an immediate and deep transition of the global society.
