A group of researchers led by Federal Polytechnic School of Zurich - ETHZ - published the first global analysis focused on future changes in climatic conditions in some cities of the world, as a consequence of global warming. The results were collected in the study entitled "Understanding Climate Change from a Global Analysis of City Analogues", Published on PlosOne.

According to what the experts have highlighted, the climate future that awaits us will not be rosy at all.

I study

The research analyzed over 520 cities, highlighting the high probability that the most representative locations in the world will significantly change their climatic conditions. By 2050, the climate we currently know will be very different. Summer temperatures will be on average 3.5 ° C higher than today, while in winter the thermometers will show 4.7 ° C more. In a similar framework, Milan will become like Dallas, in Texas, while Rome like Adana, in Turkey. The climate of Madrid will be similar to that of Marrakech. Stockholm will resemble Budapest, London to Barcelona, ​​Moscow to Sofia, Berlin to Canberra.

As a general trend, the researchers found that all cities are gradually taking on the characteristics of subtropics. This means that the climate of the locations belonging to the northern hemisphere is becoming increasingly warm and on average more similar to that of cities located about a thousand kilometers further south. Tropical cities, on the other hand, are getting drier.

As explained by the authors, this assessment first of all simplifies the understanding of climate change globally. The study also represents a valuable aid for administrators and planners who can have a vision on the future climatic conditions of their respective cities, thus implementing an effective decision-making process in response to ongoing climate change.

Climate Change: cities in 2050

The research results can be viewed in the appropriate interactive map made by experts.

In 2050 the collapse of ecosystems

2050 seems to be a crucial date for the fate of our planet. A further study conducted in Australia and published by Breakthrough National Center for Climate Restoration has identified precisely in this year the moment in which the various terrestrial ecosystems, from the Arctic to the coral reef, could collapse as a result of the climate crisis.

The picture drawn is more than alarming. The authors predict that 35% of the earth's surface, on which 55% of the world population lives, could be hit for at least twenty days a year by unbearable heat waves; 30% could be destined for desertification; entire areas of the Mediterranean, western Asia, the Middle East, the southwestern United States and the Australian outback could become unlivable. The report also states that cities such as Hong Kong, Mumbai and Bangkok could be abandoned due to thesea ​​level rise. There scarcity of water resources it could affect as many as two billion people, resulting in an inevitable one implosion of world agriculture.

All this, according to the scientists, could lead to at least one billion "climate refugees" and an endless series of wars and famines.

In short, projections for the future do not allow us to sleep peacefully. What will really happen in 2050, if a sudden and responsible change of course is not achieved today?
