For the last few months, Europe’s smoldering heatwave has been wreaking havoc across the region, causing destructive wildfires, severe droughts, and thousands of deaths.

The EU’s record-breaking temperatures are making headlines around the world, as experts worry these extreme heatwaves could be the region’s new normal.

Europe's heatwaves

Given the volume of coverage on the topic, we sifted through dozens of articles and Twitter threads (so you don’t have to) and complied a list of the five major things to know about Europe’s smothering heatwave.

1. High temperatures are shattering records

Temperatures have been hitting all-time highs across the region.

On Monday, July 18, dozens of towns across France reported record-breaking temperatures of up to 42°C (107.6°F). In the same week, the U.K. experienced its hottest day on record at 40.3°C (104.5°F), breaking Britain’s previous record of (38.7°C) 101.7°F that was set back in 2019.

The heat in London was so unprecedented, the city’s national rail service issued a warning to the public, urging passengers to stay home and only travel if necessary. Some major rail lines were even closed for parts of the day on Tuesday, July 19.

2. Europe is feeling the heatwave burn

The smoldering heat is fueling disastrous wildfires across the continent. As of July 20, an estimated 1,977 wildfires have blazed across the region in 2022—almost 3x the average amount, according to historical data from the European Forest Fire Information System.

Mediterranean countries have been hit particularly hard, with thousands of people in Portugal, Spain, and France evacuating their homes.

3. Going with the (low) flow

Along with the devastating wildfires, Europe’s heatwave is also causing a series of droughts across the region.

While most European cities have at least one river or lake crossing their urban landscape, these rivers and bodies of water are at risk of drying out. For instance in early July, Italy’s Po River was experiencing a drought so severe, that the country’s government issued a state of emergency in five different regions.

4. Energy demands are creating an awkward situation

Last year, Europe set ambitious goals to cut 55% of its greenhouse gas emissions by 2030.

But, in the wake of a global energy crisis, many European countries have put their green transition plans on hold as they turn to “dirtier” fuels like coal to keep their economies running business-as-usual. This timing is a tad awkward, considering the fact the region is currently ablaze with record-breaking temperatures that experts believe are human-induced.

The aforementioned “low flow” on many European rivers are also impacting hydroelectricity and even nuclear electricity generation, as too little water is available for cooling purposes.

On the bright side, at least Germany has made some progress in the realm of renewable energy—on July 17, the country generated a record-breaking amount of electricity from solar panels.

5. Climate change is a factor, but heatwaves are complicated

Experts claim that climate change is playing a part in these record-breaking heatwaves. Around the world, global surface temperatures have risen by about 1.0°C (1.8°F) since the 1850s, and scientists claim this temperature increase has been indisputably influenced by human activity.

However, there may be other factors that are influencing these extreme heatwaves. While the exact specifics are difficult to nail down due to the variable nature of the climate, a recent study published in Nature Communications found that Europe’s escalating heatwaves could be partly attributed to changing air currents, which are blowing hot air from North Africa to Europe.

The bottom line

At least 1,500 lives have been lost so far amidst this record-breaking heatwave. And since temperatures are expected to remain high across the region for at least another week, this figure will likely increase.

European homes are generally not well equipped for exceptionally high temperatures, and since the continent has the oldest median age of any region, its population is particularly susceptible to the negative effects of extreme weather.

Livelihoods are also being impacted by the extreme weather. Temperatures are drying out soil, which is creating poor growing conditions for corn farmers in France, Romania, and Spain, the region’s top corn producers.

Long story short—Europe’s heatwave is having disastrous effects on its economy and infrastructure, as well as the overall wellbeing of the region’s population.
