✈️🚆🛣️ Ever wondered why your summer travel gets delayed?
Extreme heat isn’t just uncomfortable — it can literally break the systems we rely on to move around.

As climate change drives more intense and frequent heatwaves, transport networks around the world are struggling to keep up:

🔥 Airports:
High temperatures reduce lift, forcing planes to lighten loads or wait for cooler conditions. Yes, heat can keep a plane on the ground.

🔥 Railways:
Metal rails expand and sometimes buckle in extreme heat. Overhead power lines can sag. Trains must slow down, and delays pile up.

🔥 Roads:
Asphalt softens, concrete cracks, and road surfaces deform — meaning repairs, closures, and even more travel chaos.

Unless transport systems adapt to rising temperatures, we’ll see even more delays, disruptions, and breakdowns in the years ahead.

🌡️ Extreme heat is shaping the future of travel — and it’s time to prepare.
