Europe faces a future of increasingly common heatwaves, according to the World Meteorological Organization (WMO). These events, driven by the advance of global warming, are on track to become more frequent, intense, and long-lasting.
Impact of global warming on European heatwaves
In the European continent, temperatures have already reached levels typical of midsummer. Switzerland has recorded values close to 38 degrees, while in the United Kingdom they exceed 36 degrees. These extreme conditions increase the risk of droughts and wildfires.
The WMO explains that this early onset of extreme temperatures marks a concerning climate change. Europe is experiencing an irreversible change in its climate, where summer heat peaks are becoming a new normal, surpassing scientific expectations.
A persistent system of high pressures is responsible for blocking fresh air currents while dragging warm air from the African desert. This phenomenon creates an unprecedented vicious cycle of extreme heat.
According to the WMO, due to sustained global warming, extreme weather events will cease to be rare and become common in Europe. The continent is warming faster than the global average, facilitating the occurrence of record temperatures even at the beginning of summer.
This climate change generates significant impacts on public health, agriculture, water resources, and ecosystems, forcing governments to strengthen their heat adaptation strategies.
A key factor is the so-called omega block, a configuration of high atmospheric pressure that persists for days, preventing the arrival of cooler air and favoring the accumulation of heat from North Africa.
The likelihood of Europe experiencing heatwaves increases with the continuity of these blocks, which can last for weeks, raising the possibility of extreme weather phenomena.
Since the great heatwave of 1976, the average temperature in Europe has increased by approximately two degrees. This baseline increase in temperatures makes it easier for current warm events to start from a higher level, setting new records before full summer.
Extreme temperatures not only affect human well-being but also reduce soil moisture and decrease precipitation, increasing the vulnerability of large areas in Europe.
France, for example, is concerned about the growing risk of wildfires, while other countries anticipate water restrictions and damage to heat-sensitive crops. Experts urge Europe to prepare to live with heatwaves, prolonged droughts, and greater health impacts.
The WMO emphasizes that these events are consistent with scientific forecasts, which have anticipated an increase in the frequency of extreme weather phenomena.
In addition to reducing greenhouse gas emissions, urban adaptation, improvement of early warning systems, and protection of the most vulnerable populations are highlighted as essential.
Europe will need to prepare for a future of heatwaves, but the severity of their consequences will depend on the adaptation and mitigation measures implemented in the coming years.
