Japan has just seen itself through its hottest July recorded since 126 years ago, reported The Asahi Shimbun.

This is the second consecutive year of record-breaking temperatures for Japan.

This year, the average July temperature was 26.22°C, the highest ever since 1898 from when such data was first available.

According to the Japanese Meteorological Agency (JMA), temperatures reached 2.16°C higher than average, topping last year’s July record of 1.91°C above average.

The cause behind the heat is said to be due to a strong high-pressure system in the Pacific Ocean, westerly winds bringing in warm air, and global warming. 

Heatstroke alerts issued

As a precautionary measure, heatstroke alerts have been issued by the JMA for 38 of Japan’s 47 prefectures, according to The Japan Times. 

As temperatures soared, data drawn from the Japan’s Fire and Disaster Management Agency (FDMA) showed that 12,666 people were transported to hospitals in the week of Jul. 22 to Jul. 28 alone due to heat-related illnesses.  

On Jul. 7, six people died from heatstroke in Tokyo, and temperatures reached over 40°C in Shizuoka prefecture.

The Mainichi and The Guardian previously reported that the surge in heat-related illnesses have stretched local hospitals to their limits.

This led to the Japanese Association for Acute Medicine to revise its three-level classification of heatstroke severity to a four-level one, with a "most severe" category to be added later this year. 

For now, the heat is expected to continue through August and beyond, The Asahi Shimbun reported the head of the JMA's climate information division’s forecast team, Masayuki Hirai as saying.

Extreme heat across the globe 

It is not just Japan that has been experiencing extreme heatwaves. Record-breaking temperatures have been observed all over the world. 

In Barcelona, Spain, temperatures have peaked at 40°C, the highest in at least 110 years of records.

Likewise, Bangkok, Thailand experienced a wave earlier this April that killed 30 individuals. 

According to the European Union’s Copernicus Climate Change Service which has tracked global weather patterns since 1940, the world saw its hottest day on Jul. 21 this year. 

The International Labour Organisation reported that heat alone is estimated to kill almost half a million people a year.
