This image is an example of the retreat of ice due to global warming. The climatic changes are habitual in the History of the Earth, and mark our evolution. We all descend from a small group of men who survived an Ice Age during the Pleistocene. There are also climatic changes in our recent history.
Between the 10th and 15th centuries there was a global warming that ended the ice of Greenland (in fact, Greenland means "green land"). It is the so-called medieval optimal climate. It favored crops, resources increased and the population grew. It helped society to prosper throughout the Middle Ages and enter the Renaissance.
From the 16th to the 19th centuries, the weather cooled again and the Little Ice Age entered. There is talk of years in which there was no summer in Europe.
Since the mid-twentieth century, global warming is accelerating climate change. Human performance is one of the causes. The use of fossil fuels breaks the natural carbon cycle. Excess CO2 pollutes the atmosphere, damages the ozone layer and increases the greenhouse effect. Radiation cannot escape and the temperature rises.
Perpetual ice and snow melt, sea level will rise and wide coastal areas will disappear. Droughts will bring famine and mass migration. Many species will become extinct and the ecosystem's balance will be broken. The current climate change will condition our future.
