Scientists warn that over the course of this century, the regions of the earth that too hot for humans will triple, mainly due to the increase in temperatures. From an increase of 0.5 °C compared to the pre-industrial levels could make about 35% of land areas inaccessible to people over 60, while at 2°C of global warming an area equivalent to that of the United States will be affected. The transition to renewable energies is therefore crucial.
The most important thing in brief
- The to hot regions for people will be by the end of the century triple.
- At 2°C Global warming will be an area that the United States corresponds to be uninhabitable.
- Approximately 35% of land areas inaccessible be for older people.
- Extreme conditions require one Preparation on the inevitable Climate change.
Regions that are too hot for humans will triple over the course of this century
According to recent studies, scientists predict that if current global warming trends continue, the regions of our Earth that are becoming too hot to support human life will triple over the course of this century. These alarming forecasts are based on an expected increase of 0.5°C compared to pre-industrial levels, underscoring the urgency of taking action on this global challenge. When the temperature is around 2°C increases, an area equivalent to that of the United States will be declared uninhabitable due to excessive heat.
Impact on older and vulnerable populations
The consequences of this phenomenon are not limited to a simple increase in temperatures. Approximately 35% of the land area will become inaccessible to people over 60, who are particularly vulnerable to heatwaves. Since the rise in global temperatures is already 1.5°C has reached, the danger for the population in these regions, especially for older people, whose resilience to heat is often impaired, is becoming ever greater.
Heat limits at 4 °C warming
It is also predicted that so-called “incompressible” Heat limits up to 40% of the land surface will be affected if there is a warming of 4°C comes. These borders would lead to inhumane climatic conditions, making some areas completely uninhabitable. Regions like that Gulf of Persia and the south of the United States are already experiencing extreme heatwaves, highlighting the tragic realities of climate change.
The threat of unsurvivable heat
Scientists have critical thresholds for what they consider “unviable” Heat refers to identified, characterized by body temperatures within less than six hours 42°C exceed. This poses a significant risk to human security, particularly in areas where supporting infrastructure, such as cooling and access to water, is inadequate. The need for a transition to renewable energy sources therefore becomes crucial to limit global warming and its effects.
Access to cooler environments
It is also crucial to ensure people have access to cooler environments to escape the extreme heat. Research shows that well-designed cities with green spaces and infrastructure that lower local temperatures can help mitigate this problem. This requires thoughtful urban planning and concerted efforts to transform our communities into livable havens in the face of increasingly extreme weather.
Preparation for extreme climatic conditions
Climate change requires rigorous preparation for increasingly dangerous external conditions. These include water management strategies, strengthened health systems to protect vulnerable groups, and increased awareness of how to deal with the effects of extreme heat. As science warns of the increasing risks of climate change, it is essential to take immediate action to strengthen the resilience of our societies in the face of this colossal challenge.
