Extreme heat has hit Europe, North Africa, the Middle East and Asia, with temperatures exceeding 40 degrees Celsius (104 degrees Fahrenheit) in many places, causing wildfires and deaths related to heat.
On Friday, the UK Met Office issued its first-ever red ‘extreme heat’ warning for Monday and Tuesday across much of England, including London and Manchester, as temperatures are forecast to exceed 40C, this making it the hottest day on record. The current record temperature in the UK is 38.7°C (101.6°F), recorded in Cambridge on July 25, 2019.
The UK Health Safety Agency has also raised its heat-related health warning from level three to level four as hospitals prepare for a spike in heat-related admissions. Residents were advised to try to stay out of the sun between 11 a.m. (10 a.m. GMT) and 3 p.m. (2 p.m. GMT), drink plenty of fluids and avoid physical exertion.
How is temperature measured
The temperature you see in the news or on your phone’s weather app is based on a network of weather stations positioned around the world.
To ensure accurate readings, weather stations use specialized platinum resistance thermometers placed in shaded instruments known as Stevenson screens at a height of 1.25 to 2 meters (4 to 6 feet) above the floor.
There are two well-known scales for measuring temperature: Celsius and Fahrenheit.
Only a few countries, including the United States, use Fahrenheit as their official scale. The rest of the world uses the Celsius scale named after Swedish astronomer Anders Celsius who invented the freezing and boiling point scale from 0 to 100 degrees in 1742.

The world is heating up
The global average temperature at the Earth’s surface in 2020 is tied with 2016 as the warmest year on record. Collectively, the past eight years have been the hottest since modern record keeping began in 1880, according to NASA.
This annual temperature data is the global temperature record, which tells scientists that the planet is warming.
According to NASA’s temperature record, Earth in 2021 was about 1.1°C (1.9°F) warmer than the late 19th century average.
