The international community needs to put more effort into stopping negative environmental trends; otherwise the current situation could have disastrous consequences for humanity, Stefan Rahmstorf, professor at the Potsdam Institute for the Study of Climate Change, said.
The analyst warned of mass disasters that could wipe whole cities and islands off the map.
"We are witnessing an accelerated rise of the sea level, which in the long term, if not stopped, will lead to the disappearance of coastal cities and countries. It would be just stupid to rush into the catastrophe at a breakneck speed," the analyst said.
According to Rahmstorf, the first climate warning came 25 years ago, but since then, the trend has not improved.
"For example, in my field of research, climate, we can observe the ongoing serious increase in carbon dioxide emissions, and, consequently, the increase in the concentration of carbon dioxide in the atmosphere, which is now higher than ever over the last 3 million years. All this, consequently, leads to the further growth of global temperatures," Rahmstorf added.
The climatologist, for instance, expects the new German government to take concrete steps that will lead to the implementation of all climate goals.
According to him, the prospects for improvement are relatively high.
"When we talk about climate, first of all, it is necessary to reduce greenhouse gas emissions to zero. The fact that all countries, with the exception of the United States, have realized this is already somewhat a great success," Rahmstorf concluded.
The letter called "World Scientists' Warning to Humanity: A Second Notice" was published in the scientific journal BioScience.
