Malta’s Heatwaves: The Silent Killer

Imagine this: Malta’s sun, usually a welcome friend, turns into an invisible foe. Last summer, temperatures soared to 41°C in Żebbuġ. It was a heatwave, but it wasn’t the sunburns that should worry us. It was the silent killer lurking in the shadows.

Heatwaves: The Invisible Threat

Heatwaves, like the one that gripped Malta in 2021, are more than just uncomfortable. They’re deadly. According to the European Environment Agency, heatwaves cause more deaths than any other extreme weather event. Yet, they’re often overlooked, their victims often unseen, their cause often misunderstood.

Malta’s Heatwave Hotspots

Not all parts of Malta feel the heat equally. Urban areas like Birkirkara and Sliema, with their concrete jungles, can be up to 5°C hotter than rural areas like Dingli or Mgarr. This ‘urban heat island’ effect makes life harder for the elderly, the sick, and the poor, who often live in these hotspots.

Take St. George’s Square in Valletta, for instance. Its lack of greenery and shade makes it a heat trap. Last summer, temperatures here reached 45°C. Imagine sitting in that square, your body struggling to cool down, your life at risk, and no one around to notice.

Heatwaves: The Silent Killer

Heatwaves don’t just kill through heat exhaustion. They exacerbate existing health conditions. They trigger heart attacks, strokes, and respiratory problems. They cause dehydration and heatstroke. They even increase the risk of dementia. And they don’t discriminate. They affect everyone, but the vulnerable – the elderly, the young, the sick – suffer the most.

But here’s the thing: heatwaves aren’t natural disasters. They’re man-made. Climate change is making them hotter, longer, and more frequent. And Malta, with its Mediterranean climate, is one of the most vulnerable countries in Europe.

So, what can we do? We can start by acknowledging the threat. We can check on our neighbours, especially the elderly. We can plant more trees, create more green spaces. We can demand better urban planning, more shade, more cooling systems in public spaces. We can push for stronger climate action.

Because heatwaves are silent killers. But we don’t have to be silent about them. We can raise awareness. We can demand change. We can save lives.
