Billions of people worldwide could die of heat by 2100

In a study published in the scientific journal Nature Sustainability, researchers The world will experience an alarming temperature rise in the coming years. In fact, the climate is expected to rise by about 4.8 degrees, i.e. above pre-industrial levels, by the mid-2100s. Unfortunately this can cause thousands of deaths and the highest death tolls are in India, Nigeria, Indonesia, the Philippines and Pakistan.

The study revealed that if we manage to limit the global temperature rise to the target (1.5 degrees Celsius) set by the Paris climate agreement in 2015, we can drastically reduce the number of people exposed to the dangers of rising temperatures. With the decline, peak heat will only affect about half a billion people out of the estimated total of 9.5 billion people by 2100.

As the research explains, global temperature is already affecting millions of people in different countries: 600 million people live in India; 300 million in Nigeria; 100 million in Indonesia; and 80 million in the Philippines and Pakistan. Right now, A temperature rise of 1.2°C is already causing heatwavesdrought and forest fires in different parts of the planet.

Worrying heatwave engulfing the whole world

“This is a profound redesign of the habitability of the planet’s surface and could potentially lead to large-scale reorganization of where humans live. The costs of global warming are often expressed in financial terms, but our study highlights the extraordinary human cost of not addressing the climate emergency. For 1°C warming, about 140 million people will be exposed to dangerous heatsaid Tim Lenton, lead author and director of the Global Systems Institute at the University of Exeter.

The scientists analyzed the mean annual temperature (MAT) and found that it reached 29°C. Typically, temperatures are described in two distinct regions: the average climate in temperate regions is 13°C; in tropical areas this number rises to 27°C. So the rise to 29°C is already a concern.

To reduce extreme heat events around the world, governments aim to make changes that do not cause adverse effects on the environment, such as the transition of energy to a more sustainable format.

These and other scientific discoveries should serve as a wake-up call for urgent and coordinated global action. The need to reduce carbon emissions and take preventive measures is coming closer than ever. After all, it is not in vain that the protection of our planet and human life is at stake.
