Daily US Times: A global analysis has found that the number of extremely hot days every year when the temperature reaches 50C has doubled since the 1980s.
The extreme temperature also now happens in more areas of the world than before, presenting unprecedented challenges to our health and to how we live.
The BBC analysis has found that the total number of days above 50C has increased in each decade since 1980. On average, temperatures passed 50C about 14 days a year between 1980 and 2009, while the number rose to 26 days a year between 2010 and 2019.
In the same period, 45C temperatures and above occurred on average an extra two weeks a year.
Dr Friederike Otto, associate director of the Environmental Change Institute at the University of Oxford, said: “The increase can be 100% attributed to the burning of fossil fuels.”
Extreme temperatures become more likely as the whole world warms.
High temperatures can be deadly for humans and nature, and cause major problems to roads, buildings and power systems.
The 50C heat happens predominantly in the Gulf regions and in the Middle East.
After the record-breaking heatwave of 49.6C in Canada and 48.8C in Italy this summer, researchers have warned that days over 50C will happen elsewhere unless we cut fossil fuel emissions.
Dr Sihan Li, a climate researcher of Oxford, said: “We need to act quickly. The faster we cut our emissions, the better off we’ll all be.”
