The effects of climate change are an increasingly pressing concern in our modern world. Heat waves are just some of the phenomena that are increasing in intensity and frequency, along with tropical storms, hurricanes, droughts, and other extreme weather events that affect the lives of millions of people. To quantify the expected future damage due to these changes, a study published in The Lancet Planetary Health paints an alarming picture.
According to the study, climate disasters of this magnitude are projected to cause up to 152.000 deaths per year in Europe between 2071 and 2100. This alarming figure suggests that two out of every three people living in Europe by the end of this century could be affected by extreme weather events, increasing the likelihood of mortality.
Increase in extreme events
This analysis focuses on studying the various effects of climate change that could manifest in the not-too-distant future. Seven key disasters are identified in the study: heat waves, cold waves, wildfires, droughts, floods, and blizzards.
Awareness about climate change has not yet spread sufficiently around the world. These changes represent one of the greatest threats to human health in the 21st century. As climate disasters become more frequent, the associated risks increase, affecting not only communities but also economic systems and infrastructure.
If urgent measures are not taken to reduce global warming, it is estimated that 350 million Europeans could be exposed annually to extreme weather events by the end of this century.
Forzieri's group conducted a comprehensive analysis, reviewing records of approximately 2.300 climate disasters that occurred in Europe between 1981 and 2010. The results showed the growing vulnerability of the population to these phenomena. Although global targets such as those of the Paris Agreement have been established, even their fulfillment would not be enough to prevent global warming from exceeding 2 degrees Celsius. In this context, heat waves are emerging as the deadliest phenomenon, potentially causing the majority of deaths associated with extreme weather events.
These data are not just alarming numbers; they are a wake-up call to the grave reality we face if we do not act decisively. The future predictions are grim, issuing an urgent call to action.
Impact of climate change on health
Climate change has a direct impact on human health . More intense heat waves can lead to an increase in deaths related to cardiovascular and respiratory diseases. According to the World Health Organization (WHO), climate change is the greatest threat to global health in the 21st century. Its effects manifest themselves through direct impacts, such as heat waves, droughts, and severe storms, as well as indirect impacts that affect food security and water availability.
Furthermore, public health could be threatened by an increase in the spread of emerging diseases resulting from global warming and ecosystem disruption. For example, vector-borne diseases such as dengue and Zika will become more common due to climate change. Malnutrition and the forced displacement of affected populations will also increase significantly as a consequence of food and water insecurity. According to estimates, the deterioration of global health could lead to a significant increase in respiratory illnesses due to declining air quality, exacerbated by climate change.
Water scarcity is also projected to affect nearly 3.000 billion people if temperatures continue to rise. In this regard, we must recognize the interconnectedness of human health, ecosystems, and climate. If water sources are compromised, the ability of communities to survive and thrive will be severely impaired.
The future effects of climate change on health appear to be increasingly worrying, making it crucial to prepare for an increase in diseases as mentioned in our article on the impacts on pregnant women.
Economic effects of climate change
The impacts of climate change are not only ecological and health-related. They also have a devastating effect on the global economy . Businesses are beginning to feel the financial impact of extreme weather events; damaged infrastructure and crop losses are starting to reverberate through regional economies.
Climate change is estimated to push between 32 million and 132 million people into extreme poverty over the next decade. This increase in poverty will be exacerbated by declining agricultural production and rising costs for basic resources such as water. In Europe, increased economic losses due to climate change are anticipated, which will further strain public health and social systems.
One of the most visible economic impacts can be seen in the agricultural sector , as the productivity of key crops such as maize, wheat, and rice is expected to be increasingly affected by extreme weather events, reducing their yields by at least 5% in major producing regions. A 2-degree temperature increase could have even more devastating effects, especially in vulnerable areas such as sub-Saharan Africa and Southeast Asia, where food security will be significantly compromised. This will not only lead to famines but will also disrupt international food markets, impacting economies that depend on agriculture.
As weather events become more extreme, their associated costs also increase. For example, emergency and disaster management, as well as the rehabilitation of damaged infrastructure, are placing a considerable financial burden on governments. Projections suggest that economic losses could become staggering if adequate mitigation measures are not implemented.

Projections for the future
The future of climate change is uncertain, but scientists have established certain scenarios based on current data. The Intergovernmental Panel on Climate Change (IPCC) has indicated that if greenhouse gas emissions continue at the current rate, the average global temperature is expected to rise by 2,3 to 2,7 degrees Celsius by the end of the century. This temperature increase will have disproportionate effects on different regions, intensifying droughts in some areas while causing floods in others.
It is predicted that, if drastic measures are not taken to curb global warming, extreme weather events will become more frequent and severe. Particularly worrying are the reports of Arctic ice melt, which contributes to sea level rise. With a projected increase of up to 6,6 feet by 2100 , many coastal cities could face severe flooding, displacing millions of people from their homes.
Furthermore, climate change will affect the quality of life in regions where climatic conditions have traditionally been stable. Projections indicate that droughts will intensify, increasing competition for scarce resources, while the wildfire season is expected to be longer and more destructive. The interaction between these phenomena creates additional strains on public health and the global economy. In this regard, it is interesting to read about the cities that could disappear due to these changes.
Given these projections, it is essential that nations work together to implement effective strategies to mitigate and adapt to the effects of climate change. This includes the transition to renewable energy, the development of resilient infrastructure, and changes in consumption patterns to reduce the global carbon footprint. Establishing international agreements and local measures will be key to addressing this global challenge.
The future of our planet depends on the decisions we make today. Immediate action can not only alleviate human suffering but also ensure that future generations can enjoy a healthy and livable world.
