This is a video posted on social media by a man in France as record-breaking heatwaves hit across Europe.

According to World Health Organization (WHO) statistics, more than 1,300 people have died in Europe so far as the "omega heat dome" phenomenon, which traps hot air for extended periods, strikes the continent.

It is estimated that in France alone, there have been over 1,000 more deaths than the average for a typical summer.

As the heat dome moves eastward, damage is continuing to spread across Central and Eastern Europe.

The WHO Director-General stated on social media that "since June 21, there have been over 1,300 excess deaths related to the record-breaking heatwave in Europe."

Excess deaths refer to the difference between the number of deaths expected during a specific period based on historical statistics and the actual number of deaths that occurred.

The WHO Director-General pointed out that "heat stress is called a 'silent killer,'" adding that "homes, workplaces, and schools in Europe were not designed for such temperatures."

As tens of millions of people across Europe spent the weekend in deadly scorching heat, warnings have emerged in some countries that the death toll could surge and healthcare systems could become paralyzed.

In particular, Germany, the Czech Republic, Hungary, and Poland are reported to be suffering severe damage from the heatwave.

In Germany, temperatures in the central-eastern region reached 41.5°C (107°F) on June 27, marking the third consecutive day of record-breaking high temperatures. The Czech Republic also broke its record for the highest temperature for two days in a row, with the northern city of Doksany reaching 41.1°C (106°F).

The WHO Director-General warned, "Due to climate change and global warming, heatwaves that used to occur once in a generation are now happening almost every year," adding that "Europe is the fastest-warming continent on Earth, heating up twice as fast as the global average."
