On August 10, 2003, the United Kingdom records its first-ever temperature over 100 degrees Fahrenheit. Throughout the month, an intense heat wave scorched the European continent, claiming more than 35,000 lives. August 2003 was the hottest August ever recorded in the northern hemisphere and broke all previous records for heat-related deaths. France was the worst hit, with almost 15,000 victims, followed by Germany, where approximately 7,000 people died. Thousands also died in Spain and Italy. A majority of the victims were elderly, very young, or chronically ill. When a person experiences extreme heat, their bodies can struggle to cool themselves—which can prove especially dangerous in the very old, very young or already ill. If a person’s internal body temperature reaches 104 degrees Fahrenheit, the organs can began to fail and the person can eventually die. The Washington, D.C.-based Earth Policy Institute estimates that more people die every year from heat than floods, tornadoes and hurricanes combined. In addition to directly causing deaths, the extreme heat also caused massive fires. In Portugal, 10 percent of the country’s forests were destroyed and 18 people were killed in the fires. The heat also caused glacial melt, flash floods and avalanches in Switzerland. In July of 2022, temperatures in England topped 104 degrees Fahrenheit, shattering all previously held records in the U.K. Worldwide, July of 2023 was the hottest month ever recorded. Scientists project that, because of global warming, the earth’s average temperature will continue to rise, reaching 42.44 degrees Fahrenheit by the end of the century, a gain of 2.5 degrees. The only way to stop the rise in global temperatures and extreme weather catastrophes is to reduce levels of the carbon-dioxide emissions that contribute to global warming.
