The most intense heat waves in history

Heat waves blaze across Europe, US, and Asia, July marks hottest days on record for entire planet

18/07/23 | StarsInsider

LIFESTYLE Extreme weather

The globe is warming up, with summers getting hotter every year.

The beginning of July was the hottest week on record for the planet as a whole, according to the World Meteorological Organization, and blisteringly high temperatures are being reported across the world in Europe, the US, and Asia, breaking records on multiple continents. Millions of people in the South of the US have endured weeks of a heat wave, and in places like Spain, Greece, and Canada, wildfires are raging. At the same time, torrential rains have inundated parts of Japan, China, South Korea, and India, upending the lives of millions and causing flash floods, landslides and power cuts. The heat is wreaking havoc on the world in ever clearer evidence of the climate crisis, and might be the worst our planet has seen yet.

If you remember, June 2018 was one for the history books. The Northern Hemisphere was hit by many heat waves, affecting Europe, Asia, Africa, and North America. The earth's surface temperature was the fourth highest in 140 years. Scientists claim that air currents slowed down, trapping areas of cloudless high pressure. According to the World Meteorological Organization, climate change is to blame for the high temperatures, which have a huge effect on mankind. Elderly people have an increased mortality, while crop yields suffer. Meanwhile, the Baltic sea saw its biggest algae bloom in decades, poisoning water around the world.
