Hydrofluorocarbons (HFCs) are one of the most powerful inducers of global warming as they trap thousands of times more heat in the Earth's atmosphere than carbon dioxide (CO2) and remain in it. Its emissions are growing at a rate of 10% per year, especially in developing countries.
From the earliest times, climatic variations shaped the destiny of humanity and human beings reacted by adapting, emigrating and developing their intelligence.
During the last ice ages, ocean levels dropped and men moved across continental bridges from Asia to America and the Pacific islands: Since then, numerous migrations, changes, and also catastrophes have been recorded. Some of these originated in small climatic fluctuations, with centuries of slightly higher or lower than average temperatures, plus prolonged droughts. The best known is the small ice age, recorded in Europe, at the beginning of the Middle Ages, which caused famines, riots and the abandonment of the northern colonies, both in Iceland and Greenland. Man endured weather vagaries for millennia, resorted to his ingenuity to adapt, unable to influence phenomena of such magnitude.
Today it is a scientific fact that the global climate is in danger, altered by human beings, from the Industrial Revolution to the present day, due to the increase in concentrations of greenhouse gases, such as carbon dioxide, methane, nitrous oxides and chlorofluorocarbons. These gases trapped an increasing portion of terrestrial infrared radiation and are expected to increase the planetary temperature by 1.5 to 4.5 ° C (the so-called Greenhouse effect or Global warming).
According to the signed agreement, called the “Kigali Amendment”, the calendar foresees that a first group of developed countries will reduce their production and consumption of HFCs by 10%, at the end of 2019, in relation to the levels of the years 2011 - 2013, and 85% before 2036 and 85% before 2,036.
China, today the second power in the world, and a second group of developing countries plus African countries, should achieve a reduction of 10% with respect to the levels: from 2,020 to 2,022, by the year 2,029, and from 80 % for the year 2,045.
India, Pakistan, Iran, Iraq and the Gulf countries will not begin to decrease them until the year 2,028; they will be to reduce them by 10%, with respect to the period 2,024 - 2,026, in the year 2,032, and by 85%, in the year 2,047.
Global warming is a risk that cannot be allowed to remain hidden. I ask: In which group is La Argentina located or will it be located?
The defense of life is a fight that we must incorporate into our agenda, because it compromises the human condition. We must sensitize the awareness of those who have not yet realized the seriousness of the problem and generate solidarity ties that allow to reverse the current historical trend that will lead towards the abyss of self-destruction as a species, that is, towards the true end of history.
