Without descending into sensationalism, the subject is too serious for that, it is not clear that governments are recognizing the seriousness of the problem before it is too late. Not only do we not lessen our emissions, but it is almost certain that we will quadruple. In this case, far from being fanciful, unfortunately, the temperature increase of 8 degrees (estimate of the Met Office Hadley Centre).
In this case, according to experts, our planet would experience temperatures similar to those that existed there 40 million years ago. At that time, the polar ice caps were not permanent and sea levels were 12m higher than today. Needless to say that many countries would be engulfed.
The Hadley Centre is already planning by 2080 if nothing is done, climate change concern:
* 50% decrease in rainfall over the Tropics (Tropical Africa, Southeast Asia, Australia). The U.S. will also see a decrease in rainfall
* Elevated sea levels in Europe, Indonesia, Ganges Delta
* Ice cover that extends over northern Europe and parts of England
