Global warming threatens the health and well-being of a third of the world’s population

“Global warming threatens the health and well-being of a third of the world’s population.” This conclusion, made by climatologists at the University of Exeter, is an alarming warning that our planet is getting hotter and hotter. According to the study, if current levels of greenhouse gas emissions continue and the Paris Agreement is not fully implemented, then by 2100, about a third of the world’s population will live in areas with dangerously hot summer climates.

Human factor

Professor Tim Lenton, one of the authors of the study, notes that “the consequences of global warming are often assessed from the point of view of financiers and economists. For the first time, we assessed the human side of this problem, the price that human health and well-being will pay for human failure in the fight against climate change “.

Causes of Hazardous Hot Zones

Researchers have become interested in how various manifestations of global warming, including further increases in temperatures, more extreme weather events and reduced precipitation, will affect the comfort of life and the ability to live without problems for large numbers of people in the most densely populated regions of the world. To answer this question, scientists analyzed the living conditions of people. Calculations indicated that most of the inhabitants of the planet are concentrated in temperature zones, where two characteristic peaks are observed, about 13 and 27 degrees Celsius. The first includes all the densely populated and most economically productive countries of the temperate climate zone, and the second – the states of South and Southeast Asia, where the monsoonal tropical climate prevails.

How people’s lives will change

It turned out that about 60 million people already now live in temperature zones where dangerously high summer temperatures periodically prevail. According to climatologists, the number of inhabitants of such regions will grow to 3.2 billion (34% of the total population of the Earth in 2100) with partial implementation of the Paris agreements. The implementation of additional commitments to reduce emissions will reduce this figure to 5% of the total number of people on the planet.

Professor Lenton and his colleagues found that many states in the Middle East, South and Southeast Asia, North Africa and South America will be particularly affected by these processes, where average temperatures will become noticeably higher than 29 degrees Celsius by the end of the century.

What do we have to do?

The results of the study show that the fight against climate change is one of the main challenges of our time. It is necessary not only to implement the Paris Agreement, but also to strengthen measures to reduce greenhouse gas emissions. It is also important to take measures to adapt to climate change in order to reduce the impact of its effects on human health and well-being.
