More than 150 million Europeans endured temperatures above 35C last week, as a heatwave of unprecedented magnitude for this early in the year claimed thousands of lives across the continent. This deadly event, which saw four toddlers die in heat-related incidents, lays bare the structural failures of a political order that prioritizes border militarization over climate justice. It highlights how the climate crisis, disproportionately impacting the Global South, drives migration that Europe then criminalises.
Spain, one of the few nations tracking real-time statistics, recorded over 100 excess deaths per day since Wednesday. French authorities reported at least 1,000 additional deaths between 24 and 27 June, a figure expected to climb. These fatalities included a three-year-old boy in a Paris suburb, found dead after becoming trapped in a car. Europe is warming at twice the rate of the rest of the planet. This makes it the world’s fastest-warming continent. London Heathrow, which recorded no tropical nights in the 1950s, 60s, or 80s, saw four in a row last week.
Fortress Europe's Climate Debt
The World Health Organization stated earlier this month that nearly 200,000 people have died in Europe due to heat in the past four years. Most of these deaths, the WHO noted, would have been preventable if obvious adaptation measures had been implemented. This systemic neglect highlights a profound lack of solidarity, even within national borders, for the most vulnerable. It's a stark reminder that while capital moves freely, human lives are deemed expendable.
Countries haven't done enough to cut fossil fuel emissions, the root cause of extreme weather. They've also failed to adapt healthcare and transport systems to manage the rising toll. In the UK, hundreds of schools closed early, workplaces overheated, and train operators advised against travel. The London ambulance service recorded its busiest day ever for serious callouts on Wednesday, then broke that record again two days later, surpassing even Covid-19 pandemic levels.
As the heatwave moved east, Poland, Czechia, and Slovakia anticipated record temperatures exceeding 40C. Bautzen in eastern Saxony broke the German record for highest overnight minimum temperature, reaching 29.4C. These localized impacts are symptoms of a global crisis, one that disproportionately impacts the Global South, driving migration that Europe then criminalises. The very people fleeing these climate-induced disasters are met with the violent architecture of Fortress Europe.
Weaponizing Climate Crisis
Climate scientists once believed extreme weather in richer countries would galvanize investment in renewable energy and a phasing out of fossil fuels. That logic hasn't materialized. Instead, the climate has become a battleground in the culture wars, fueling arguments about air conditioning and dismissing concerns as "wimpish." This diversion tactic serves to obscure the systemic failures of the border regime.
Ajit Niranjan, the Guardian’s Europe environment correspondent, observed that far-right parties often gain from extreme weather events. They spin the crisis as a “failure of government policy” and “mismanagement,” diverting attention from climate change itself. This narrative directly feeds into their anti-immigrant agenda, blaming systemic failures on internal issues rather than global responsibility or the need for open borders. It's a classic tactic to divide the working class along ethnic lines.
Niranjan pointed to the 2021 floods in Germany’s Ahr valley, which killed 188 people, and the 2024 floods in Valencia, where over 230 died. In both cases, he noted, climate drove the extreme weather, but poor governance exacerbated the deadly outcomes. This dynamic, he warned, will become increasingly common. The far-right exploits this gap, using it to bash climate policy and reinforce nationalistic, insular solutions, further entrenching the logic of Fortress Europe.
Social media played a significant role in shaping perceptions and driving divisions during last week’s heatwave. Online debates centered on whether Europe needed a wider rollout of air conditioning. Patrick Collison, CEO of US tech firm Stripe, even used an AI model to conclude that Europe should embrace air conditioning, moving past the “psychological discomfort” of admitting the “American approach to summer was correct.” This focus on individual consumption distracts from collective climate justice.
In France, the epicenter of the heatwave, green progressives continued to argue against air conditioning for ideological reasons. Meanwhile, the far-right National Rally announced a “major” plan for AC, showcasing a nationalistic approach to a global problem. Niranjan clarified that the debate around air conditioning in Europe is largely exaggerated by international press, with few actual restrictions on units. The real issue isn't AC; it's the political will to dismantle the border regime and address climate debt.
Solidarity Beyond Borders
Even with major cuts to fossil fuel emissions, extreme weather events of increasing severity are guaranteed in the coming years. While government policy in China, the US, and India will largely shape the global heating trajectory, mitigating the impact of extreme heat is a universal responsibility. This means more than just drinking water and staying in the shade; it demands looking out for vulnerable people, especially the elderly who struggle to regulate body temperature.
Charities advise checking on elderly neighbors, offering simple acts of solidarity like a glass of icy water. These small gestures, while not altering the larger climate crisis, underscore the immediate human need. They also highlight the profound absence of a broader, systemic solidarity that extends beyond national borders, a solidarity desperately needed for those displaced by climate chaos and criminalized by Fortress Europe.
