Soon, those 60 will not be able to live by a third of the Earth (literally)

IN December 2015196 countries signed the Paris Agreement in which they promised to take the necessary measures to prevent an increase in global temperature Above 2ºC Compared to pre -industrial levels. In fact, if possible, the goal should be 1.5 ºCThe field unfortunately, last year the first 1.5ºC was exceeded, and experts believe that if measures are not ultimately, it will be impossible to fulfill the Paris Agreement. The consequences will be a lot and very serious, but one of the most terrible is the fact that the third of the surface of the Earth of the planet will be unpleasant for People over 60 years old.

This is the conclusion of a study recently published in Nature reviews the Earth and the environment From the hand of the team of scientists from several British and American research centers. In this study, they analyzed the death of heat, which occurred at different points in the planet, how they developed as Climate change and to what extent they affect People over 60 years old.

It is well known that older people are more sensitive to heat. But we are not talking about people too old, but adults who, in most cases, can have an excellent quality of life when they have a place to fulfill it. That is why these data are so horrified.

The effect of heat waves on health

People are animals Homeotermes. This means that we can maintain a more or less constant body temperature regardless of Environmental temperature. It does not matter if there is 0ºC or 40ºC. As far as possible, our body remains Between 36ºC and 37ºC.

In the case of environmental heat, this is possible thanks to our Cooling systems The body that includes several phenomena. The most important is sweating, which consists of release through the skin of a liquid, consisting mainly of water. Once on the surface of the body, it evaporates. In order for water to move from liquid to gaseous, it needs heat, so it removes it from the body, reducing its temperature. All this happens in parallel with Expansion of blood vesselsEspecially those who are closer to the surface of the skin. Thus, it is preferred that more bleeding flows, therefore, more heat to extract sweat. Both phenomena work together.

Unfortunately, when the heat is too high, these mechanisms are not supplied. Therefore, body temperature He rises Above the limits to which our body is not adapted. In addition, the expansion of blood vessels can lead to a decrease in low voltage, and excessive sweating can cause dehydration. To top it off, if the environment is very wet, Sweat cannot evaporateSince the air is already too loaded with moisture, so effective cooling is not achieved.

All this leads to celebrities Heat blowsWhat can be much more dangerous in children and the elderly, since their cooling systems can be slightly weakened. Those who over 60 can begin to suffer from the consequences, although the older and more damaged have their health, the serious they will be.

What is currently 60 years old?

It is estimated that heat kills at least Half a million people year. However, WHO warns that this figure should be very underestimated and that it could be 30 times MayThe host in places such as Africa or South Asia, the temperature is so high that many people can die from the heat, but are not registered as such. In some cases, it may also not be known that this was the real reason.

In the current study, it is calculated that Between 1994 and 2023 An increase in temperature and humidity led to 2% of the Earth’s surface Be dangerous for people over 60 years old. In addition, it was proved that these 2% have been achieved quickly in recent years. And also that since the planet heats up, it becomes more irritable.

In fact, in accordance with their modeling, if the global 2ºC passes, it will be a third of the earth’s surface of the world, which will no longer be able to place these people for more than 60 years. An even larger number will be dissatisfied with the elderly.

In accordance with the one who, by 2030 1 out of 6 people It will be over 60 years all over the world. Therefore, these data are the most alarming.

If people over 60 years old also do not worry, who will do this?

Currently, one of the people over 60 in the world, Donald TrumpThe procedures began for the United States to leave the Paris Agreement. Some of the magnates who are behind the most polluting companies, for example Jeff Bezos or Amansio OrtegaThey also exceed this age. Elon Musk He is only 7 years after reaching her. It is true that money can allow a person to live everywhere. However, since this is worsening, there will be fewer places where you can run.

This is all that we worry about what is happening. But, first of all, this should be damaged by those who have already overcome or approached their sixth decades. Because they may not touch them, but they can imagine that those who come behind, when they are age and do not find a place for life.
