A record-breaking heat wave scorching Europe is so intense it has become visible from orbit. Satellite thermal imagery released today shows vast swaths of the continent glowing red, with surface temperatures far exceeding seasonal norms.

The images were captured by Earth-observing satellites equipped with thermal infrared sensors, which detect heat radiated from the ground. The data reveals a deep red band stretching from Spain through France and into Germany, indicating surface temperatures that have triggered emergency heat warnings across multiple nations.

The heat wave, which began building over the weekend, has shattered records in several cities. Meteorologists are attributing the event to a persistent high-pressure system stalled over the region, trapping hot air and preventing cooling overnight.

This event underscores the growing frequency and intensity of extreme weather linked to climate change. Scientists caution that such heat waves are becoming more common, with Europe experiencing its hottest summers on record in recent years.

However, some researchers note that satellite thermal imagery can be misleading, as it measures land surface temperature—often significantly higher than air temperature—and does not directly indicate human comfort or health risks.
