Prof. Schellnhuber: Of course, it is not possible to predict the moment when we will lose control with 100 percent accuracy, although there is a clear and demonstrable trend in this direction that has been caused by human beings. We scientists are even more concerned about the entire planetary machinery rather than simply extreme weather events such as heatwaves or torrential rain. This consists of melting ice sheets (those on Greenland, in the western and eastern Antarctic, Tibetan glaciers, etc.), changing systems of currents in the atmosphere and the oceans (Atlantic thermohaline circulation, Indian monsoon, West African monsoon) as well as the central ecosystems such as the Great Barrier Reef or the Amazon rainforest.** These tipping elements** can be imagined as the vital organs of the Earth as a body. We do not know when one of these organs will give up its function, but when it happens we will have to expect dramatic consequences. And to continue the metaphor: If one kidney fails, that does not necessarily mean the patient will die – but it can set off a dangerous chain reaction. As a result, preventative measures and treatments are called for.
