It is increasingly a crazy climate, many glaciers have melted, the snow level has risen, the forests are changing flora, the Mediterranean has been invaded by tropical species, the floods are more frequent and in cities there is an emergency smog.
That the climate has changed , and with it nature, is there for all to see.
It is a global phenomenon that threatens the very existence of planet Earth as we are used to knowing it.
This is why the agreement reached during the UN meeting on climate that took place in Paris in 2015 was defined as of historical importance.
The aim of the agreement is to contain global warming by 2100 below 2 ° C from the pre-industrial era, possibly within 1.5 ° C.
For the first time, all the countries of the planet, rich and poor, old and newly industrialized, have agreed on a gradual reduction of greenhouse gases.
So, is everything all right for this crazy climate?
From the Paris meeting to the one held in 2018 in Poland, little has been done.
The increase in global temperature already “incorporated” in the system of the atmosphere, oceans and ice will however produce changes in the coming decades.
The climatic emergency thus prompted millions of young people to protest in 1769 squares around the world in 2019 .
Inspired by the speech of the 15 year old Swedish Greta Thunberg at the 24th UN Conference, the boys started the movement “Fridays for future” and launched an appeal to the powerful of the Earth:
2018 was the fourth hottest year ever.
And in 2015 the CO2 concentration exceeded the threshold of 400 parts per million, a value that has not been recorded for 800 thousand years.
Desertification, pollution, disappearance of ice and weather-catastrophic events of unprecedented power are already a reality.
Since 1979, when satellites began to keep the Arctic under observation, an ice retreat of 12% per decade has been recorded, with an acceleration in recent years.
In addition, our oceans gobble around 10 billion kilograms of plastic each year, creating disasters along the entire food chain.
According to Mercalli, a heating of 1.5 ° C would also have important consequences, with an increase in intense atmospheric events, loss of half of the coral reefs and agricultural productivity in tropical areas, and the spread of diseases typical of warm regions.
But increasing the temperature by 2 ° C would cause the irreversible collapse of the Antarctic and Greenland ice caps, thawing of the arctic permafrost with further release of greenhouse gases, increase in sea levels of several meters.
In the event of an increase of 5 ° C, there will be a situation that would change the face of the planet, so as to put in doubt the survival of civilization, faced with the collapse of the ecosystems on which food production and the structure of the food depend. ‘economy.
That is why it is essential that the so-called clean energy sources catch on immediately.
The West has a duty to seek new clean sources of energy with the market, industry and science.
Still with an eye to emerging countries, China, India and Latin America must in fact grow without environmental chaos penalizing them.
The only sure thing is that …
… even the most banal of our actions can solve and fight pollution.
Understanding, studying is at the basis of the solution of the ecology problem,
only in this way can solutions be found to change this situation
