UNAIR NEWS – A powerful heatwave has gripped Europe since June 2025, prompting the closure of thousands of schools and claiming numerous lives. By early July, the death toll had risen to an estimated 2,300. In response to this crisis, Wahid Dianbudiyanto, S.T., M.Sc., a lecturer in Environmental Engineering at Universitas Airlangga’s Faculty of Science and Technology (FST), shared his perspective on the phenomenon.
While Europe has experienced recurring heatwaves over the past three to four years, Dianbudiyanto emphasized that this year’s event stands out as abnormal when viewed in a longer historical context. The current heatwave has shattered temperature records and caused substantial environmental disruption, he noted.
Natural forces and climate change at play
Dianbudiyanto explained that although no single definitive study has pinpointed the cause of this year’s extreme heat, two primary factors are likely at work: natural weather systems and climate change. A strong high-pressure system originating from North Africa has trapped hot, dry air over Western Europe, significantly elevating temperatures.
This weather pattern has eliminated natural cooling in drought-stricken regions. In addition, above-average sea surface temperatures in the Mediterranean have worsened the heat conditions on land. Minimal cloud cover has also contributed, allowing more sunlight to reach the surface and intensify the heatwave.
Another contributing factor is human-induced climate change. “Research shows that global warming—driven by greenhouse gas emissions—has increased the Earth’s average temperature. As a result, heatwaves are becoming more frequent and more severe. It’s highly likely this heatwave is a natural event worsened by climate change,” Dianbudiyanto stated.
Currently pursuing his Ph.D. in Belgium, Dianbudiyanto said the heat is taking a physical toll. Many buildings across Europe lack air conditioning, as they were never built to handle such extreme temperatures.
Environmentally, the heatwave has heightened the risk of wildfires and prolonged drought. It has also led to spikes in electricity consumption as people rely more heavily on air conditioning, which may contribute to further carbon emissions.
Indonesia’s growing vulnerability
Dianbudiyanto warned that regions outside Europe—including Southeast Asia—could face similar heatwaves in the future. He urged the Indonesian government to take proactive steps by developing action plans aimed at mitigating the potential impact. Strengthening healthcare infrastructure, investing in renewable energy, and integrating climate-friendly urban planning are among the strategies he recommended. He also stressed the importance of public education and regulations for outdoor workers.
For the public, Dianbudiyanto offered simple but effective safety tips. “Stay updated with weather forecasts, drink plenty of water, avoid outdoor activities during peak heat hours, use air conditioning or fans, wear light clothing, and regularly check on vulnerable individuals like the elderly and children,” he advised.
