Countries including France, Germany, Spain, Switzerland, and Portugal are expected to experience a massive heat wave starting Wednesday, with hot air coming from the Sahara. Temperatures are expected to rise as high as 40 degrees Celsius, or 104 Fahrenheit, this week. The forecast is so intense that one Spanish meteorologist tweeted, “Hell is coming.” Some 15,000 people in France died when temperatures hit similar heights in August 2003. Officials in Paris have already put the city on high alert. Scientists attribute it to global warming and warn of more such heat waves if countries don’t cut their greenhouse-gas emissions soon.

Western Europe is bracing for an intense, dangerous, and possibly even deadly heat wave this week, with temperatures due to soar as high as 40 degrees Celsius, or 104 Fahrenheit. Countries including France, Spain, and Portugal are expecting record-breaking temperatures starting Wednesday, while the rest of the continent is also set to face temperatures much higher than normal. It’s not clear when the heat wave will end. Scientists have attributed the soaring temperatures to the combination of a storm over the Atlantic Ocean and high pressure over central Europe, which is importing hot air from the Sahara.Read more: Paris opened extra swimming pools, set up mist machines – and postponed thousands of school exams – ahead of a killer heat wave looming over EuropeAdvice from @EU_ENV and @eu_echo: By 27 June, the #heatwave is expected to peak, with extreme temperatures all over the continent, with many values over 36°C and locally above 40°C.

High humidity could make it feel like 47 degrees Celsius, or 117 Fahrenheit, the BBC added. Berlin is expecting temperatures as high as 38 degrees Celsius (100 degrees Fahrenheit) by Thursday, the BBC said. Major cities like Frankfurt and Hamburg are also expecting temperatures in the mid-30s Celsius (about 95 degrees Fahrenheit). Most of Spain is expecting temperatures of at least 36 degrees Celsius (95 degrees Fahrenheit) on Wednesday, according to Spanish meteorological agency Aemet. Large swathes of Switzerland are expecting temperatures of more than 30 degrees Celsius from Wednesday, with Geneva predicted to reach 37 degrees Celsius (98.6 degrees Fahrenheit) on Wednesday and Thursday, Switzerland’s national meteorological agency Météo Suisse said. Temperatures in Portugal are expected to hit mid-to-upper 30 degrees Celsius (upper 90s Fahrenheit), and could further rise to more than 40 degrees Celsius (104 degrees Fahrenheit), Axios reported. Parts of Poland are also expected to see temperatures rise to at least 35 to 40 degrees Celsius (95 to 105 degrees Fahrenheit) this week – which is at least 11 to 17 degrees Celsius (20 to 30 degrees Fahrenheit) above normal, The Washington Post reported. Silvia Laplana, a meteorologist at Spain’s state-owned RTVE channel, tweeted images of the forecasted temperatures in the country this week with the caption: “El infierno is coming.” Infierno is the Spanish word for hell.El infierno is coming. pic.twitter.com/j0iGEYF0ge— Silvia Laplana (@slaplana_tve) June 24, 2019 The sudden spike in temperature could be dangerous because people are not accustomed to such high temperatures, which could put them at risk of heat-related illnesses, Axios said. Some 15,000 people across France died following a similarly aggressive heat wave in August 2003, when temperatures in south of France hit as high as 44.1 degrees Celsius (111.4 degrees Fahrenheit), according to France24. Officials in Paris have put the city in high alert, with schools delaying exams, and placing hospitals and care homes on high alert, Business Insider’s Sinéad Baker reported.Read more: How extreme summer heat affects your body and brainAdvice from @EU_ENV and @eu_echo: By 27 June, the #heatwave is expected to peak, with extreme temperatures all over the continent, with many values over 36°C and locally above 40°C.

Experts say climate change is making heat waves more common. Stefan Rahmstorf, a climatologist at the Potsdam Institute for Climate Impact Research told The Associated Press: “This increase in heat extremes is just as predicted by climate science as a consequence of global warming caused by the increasing greenhouse gases from burning coal, oil, and gas.” Heat waves like this will continue to worsen if countries do not cut their greenhouse gas emissions soon, a group of scientists warned in a report published earlier this month.Foto: Tourists at a fountain in front of the Pantheon monument during an unusually early summer heat wave on Monday in Rome.sourceAlberto Pizzoli / AFP / Getty Recent heat waves around the world have already proven to be deadly. At least 36 people have died during a prolonged heat wave in India, which has lasted for more than 30 consecutive days, according to CNN.
