In recent days, hundreds of deaths have been reported due to the intense heat waves that hit countries such as Canada and the United States . According to a report from the Province of British Columbia, in Canada, there are 486 sudden deaths in the last 5 days , while in the United States there are 80 . In fact, last Tuesday, June 29, a temperature of 49 ° C was recorded in Lytton. This is the highest recorded temperature in Canadian history.
These facts alarm the international and scientific community, because in the last decade it has been anticipated that by 2050 cities could reach a temperature of 50 ° C in summer, but 29 years before we are reaching those temperatures. So what temperature will we have at in 2050?
What can we expect?
The intense heat waves not only show the destruction to planet Earth that we have caused as a species and climate change as a consequence, but they also show how much the human race can withstand. And it is that, no matter how prepared we try to be, the human body has needs and limits that cannot always be satisfied or respected. Experts consider that the ambient temperature that a human being can withstand is a maximum of 55 ° C. It is believed that at 60 ° C a human being can live as little as 10 minutes before dying from extreme dehydration.
In that order of ideas, if in 2050 the common thing will be for the temperature in summer to reach 50 ° C, then the hundreds of deaths could turn into thousands and it could even be talk of a health crisis.
Why will we get to that point?
We have all heard about climate change, but very seldom do we reflect on why it is, its consequences and what we can do to stop it. We leave this task to environmentalists, politicians and the scientific community. The problem is that as long as what is being talked about in these circles does not seem practical in the real world, the problem will continue to grow and there will be less and less time to do something about it.
Calculations suggest that, if currently 50% of the world's population lives in cities, in 2050 this percentage will increase to 80% . The saturation of the population in this type of space produces strong climatic changes. The outlook is so worrying that some studies have even pointed out that the climatic conditions in which some cities will find themselves are currently non-existent.
Let us remember that among the main causes of climate change are greenhouse gases and high pollution. Although in recent years the international community has sought treaties and agreements to stop these environmental crises, the bureaucratic nature of these matters slows down processes and reduces the time available to make real and practical the actions that can be taken from the field. legal and political. However, individual changes can also make some improvements.
