At least 22 nations have recorded maximum temperatures of 50 degrees Celsius (122 degrees Fahrenheit). Al Jazeera is An International News Channel that investigates the world’s hottest spots.
Temperatures in many parts of Europe, North Africa, the Middle East, and Asia have risen above 40 degrees Celsius (104 degrees Fahrenheit), causing wildfires and heat-related deaths.
The Met Office in the United Kingdom issued its first-ever red “Extreme heat” warning for Monday and Tuesday across much of England, which includes London and Manchester, as weather conditions are projected to surpass 40 degrees Celsius, making it the hottest day on record.
The current UK record high temperature is 38.7C (101.6F), set in Cambridge on July 20th, 2019. The UK Health Security Agency also raised its heat-related warning label from tier three to tier four, preparing hospitals for an increase in heat-related admissions.
Residents have been recommended to wear sunscreen between 11 a.m. (10:00 GMT) and 3 p.m. (15:00 GMT), drink plenty of liquids, and avoid strenuous physical activity.
How is Temperature Measured?
The temperature you see on the news or in your phone’s weather app is based on a global network of weather stations.
Weather stations use specialized resistance temperature sensors positioned in darkened instruments known as Stevenson screens at a height of 1.25-2 meters (4-6 feet) above the ground to ensure accurate readings. Temperature is measured on two well-known scales: Celsius and Fahrenheit.
Only a few nations, including the United States, use Fahrenheit as their formal scale. The rest of the world uses the Celsius scale, named after Swedish astronomer Anders Celsius, who invented the 0-100 degree freezing and boiling point scale in 1742.
The Maximum Temperature ever Recorded
The map below depicts the hottest temperatures ever documented in each country on the planet. At least 22 countries have recorded maximum temperatures of 50°C (122°F) or higher.
The current highest legally registered temperature is 56.7 degrees Celsius (134 degrees Fahrenheit), which was recorded in California’s Death Valley in 1913. The highest known temperature in Africa is 55 degrees Celsius (131 degrees Fahrenheit), which was recorded in Kebili, Tunisia in 1931.
Iran holds the world record for Asia’s warmest official temperature of 54 degrees Celsius (129 degrees Fahrenheit), which was recorded in 2017.
On August 11, 2021, the highest temperature recorded in Europe was 48.8 degrees Celsius (119.8 degrees Fahrenheit) on the Italian island of Sicily.
Seymour Island in Antarctica noted a maximum temperature of 20.7 degrees Celsius in 2020. (69.3F). Temperatures on the Antarctic Peninsula have soared by nearly 3 degrees Celsius (5.4 degrees Fahrenheit) in the last 50 years, per the World Meteorological Organization (WMO).
The World is becoming Hotter.
In 2020, the earth’s average temperature tied with 2016 for the warmest year on record. According to NASA, the last 8 years have been the hottest on record since contemporary record-keeping began in 1880.
This annual temperature data contributes to global temperature data, which scientists use to make predictions. This yearly temperature data contributes to the global temperature data, which scientists use to determine whether the planet is warming.
According to NASA’s temperature record, the Earth in 2021 was around 1.1 degrees Celsius (1.9 degrees Fahrenheit) warmer than the late-nineteenth-century average.
