Europe braces for another heatwave as forecasters predict record-breaking temperatures this week
Sam Meredith | @smeredith19
Published 6:01 AM ET Tue, 23 July 2019CNBC.com
  • Much of Europe was engulfed in a sweltering heatwave from the end of June into early July, with temperatures climbing to 44.3 degrees Celsius in France's southern Vaucluse region.
  • Forecasters now expect to see another bout of extreme heat across the continent over the coming days.
  • "The U.K. will experience another pulse of high temperatures this week, with the possibility of records being broken for not only July but also all-time records," Paul Gundersen, chief meteorologist at the Met Office, said in a press statement on Monday.

The temperature in France on June 28 surpassed 45 degrees Celsius (113 degrees Fahrenheit) for the first time as Europe wilted in a major heatwave, state weather forecaster Meteo France said. Another bout of extreme weather is expected later this week.
Europe is set to endure its second record-breaking heatwave in as many months this week, with temperatures expected to climb close to and above 40 degrees Celsius (104 Fahrenheit) in several countries across the continent.
It comes after soaring temperatures worldwide made last month the hottest June ever recorded, prompting some climate groups to warn of an "ecological emergency."
Much of Europe was engulfed in a sweltering heatwave from the end of June into early July, with temperatures climbing to 44.3 degrees Celsius in France's southern Vaucluse region.

And forecasters now expect to see another bout of extreme heat across the continent over the coming days.
Wildfire risk
Meteorological service Meteo France has predicted temperatures in Paris could exceed 41 degrees Celsius on Thursday, with "absolute heat records" under threat in several cities across the country.
The French capital has never seen the mercury climb above 41 degrees Celsius. The current record of 40.4 degrees Celsius was recorded back in 1947.
The rise in extreme weather, which has been linked to an intensifying climate crisis, has made the wildfire season in Europe longer and more dangerous.
The Copernicus Climate Change Service (C3S), which is tasked with providing comprehensive climate information for the EU, has warned another anticipated period of scorching heat will amplify the wildfire risk, particularly across France, Spain and Portugal.
The CS3's Emergency Management Service (EMS) has reportedly issued the highest threat level for forest fires across almost all of France and Spain, with "high" or "very high" threat levels forecast for large swathes of Portugal, Italy, Belgium and Germany.

In the U.K., the Met Office has said the July-high temperature of 36.7 degrees Celsius and the U.K. temperature record of 38.5 degrees Celsius could both be tied or surpassed on Thursday.
"The U.K. will experience another pulse of high temperatures this week, with the possibility of records being broken for not only July but also all-time records," Paul Gundersen, chief meteorologist at the Met Office, said in a press statement on Monday.
"The weather setup is broadly similar to the pattern that brought high temperatures to much of continental Europe at the end of June," Gundersen said.
Belgium, the Netherlands and Luxembourg could also see all-time high temperatures this week, with highs of 39 degrees Celsius seen across all three countries.
July could be the warmest month ever measured on Earth
The latest continental weather warnings come after data collected by C3S showed global average temperatures for June 2019 were the highest on record for the month.
The data showed the global average temperature was 0.1 degrees Celsius warmer than the previous June record, set in 2016.
"This is significant," climate scientist Michael Mann said via Twitter last week, responding to data from Nasa also showing that last month was the hottest June ever recorded.
"But stay tuned for July numbers. July is the warmest month of the year globally. If this July turns out to be the warmest July (it has a good shot at it), it will be the warmest month we have ever measured on Earth," Mann said. (Parentheses in the quote are his).

PARIS — Europe suffered a second devastating heat wave on Thursday, with life-threatening temperatures breaking records across the continent.
The latest heat wave is one of the most intense on record, shattering all-time highs on Wednesday in Belgium, the Netherlands and Germany. Some of these stood for only one day and were beaten on Thursday, when temperatures climbed even higher from France north into Britain and eastward to Germany.
London and Paris sweltered through their hottest days on record, with numerous other cities likely to see their highest temperatures since data collection began.
Temperatures in the French capital reached a jaw-dropping 108.3 degrees Fahrenheit (42.4 Celsius) shortly after 3 p.m. local time, according to Météo-France, the national weather service, breaking the previous record of 104.7F (40.4C) set in 1947.

“No one is safe in such temperatures,” said Agnès Buzyn, France’s health minister. “This is the first time that this affects departments in the north of the country . . . populations that are not accustomed to such heat.”
“Heat waves are a serious problem for older and ill people,” Anton Hofreiter, leader of Germany’s Green Party in parliament, told Der Spiegel. He said Chancellor Angela Merkel’s government was not doing enough to support those affected and cited France as a role model.

Twenty of France’s administrative departments — from Paris north toward the English Channel — were placed on the highest possible alert level.
Elisabeth Borne, France’s minister of sustainable development, urged citizens to cancel or postpone all unnecessary travel during the heat wave, expected to last until Friday. The SNCF, France’s state-owned railway company, allowed customers to exchange or cancel free of charge any Thursday travel to the 20 northern regions particularly affected.

In Belgium, where the government activated a “code red” alert over the hot weather for the first time, some regional trains were likewise out of service because the equipment could not stand the heat.
The mercury in Belgium hit 103.8F on Wednesday, the hottest since records began to be kept in 1833, and temperatures were expected to be even hotter on Thursday.
Punishing heat — in historic cities largely without widespread air conditioning, especially in homes — has become Europe’s new normal.
In much of Europe, air conditioning has often been seen as a luxury, and even an American-style indulgence. But that is changing, said Sacha Gaillard, a technician with Les Bons Artisans, a French company that, among other things, installs air conditioners.

“We are in a situation where people cannot live,” he said, noting that the company’s air conditioning business across France has increased exponentially in the past five years. “[People] can’t sleep at their apartments. Air conditioning is no longer a comfort. It’s a necessity. It’s as if people had no heat in winter.”
Despite the widespread misery during these increasingly frequent heat waves, however, there is still resistance to the view that air conditioning is a necessity. Some still see air conditioning primarily as a threat to the environment — precisely the wrong response to crippling heat waves triggered by climate change.
There also bureaucratic concerns. Many residential buildings in cities such as Paris are centuries old and are historically classified landmarks. Their facades cannot easily be altered without the express permission of city hall or an architectural union under the auspices of the Culture Ministry.

“Nine times out of 10, you’re not allowed to drill through the walls,” said James Devlin, a British man who runs James’Clim, an air conditioning installation service in Paris. He said that because the restrictions in Paris are extensive, most of his installations take place in the suburbs and surrounding area.
“If it’s not a listed building, they’re still very restricted. You don’t have a place to put the unit on the exterior,” he said.
There is also the price: For a family-sized Paris apartment of roughly 100 square meters, or 1,070 square feet, Devlin said that installing air conditioning could cost from 12,000 to 16,000 euros ($13,300 to $17,700). Even so, in the last five to six months, he said, he has had an installation almost every day. On Wednesday, the first day of the intense heat, he received more than 40 calls for consultations.

In the meantime, cities are coordinating impromptu measures for residents to cool off. Paris, for instance, has designated air-conditioned rooms in each arrondissement, or district, as well as outdoor swimming areas and parks that stay open around the clock.
In Europe, a historic heat wave is shattering records with astonishing ease, may hasten Arctic melt

Long-term, human-caused climate change makes extreme-heat events like this one more likely to occur, more severe, and longer-lasting, according to numerous scientific studies.
For example, a recent scientific analysis, which has not yet been published in a peer-reviewed science journal, showed that the early-summer heat wave in Europe was at least five times more likely to occur in the current climate than if human-caused warming had not occurred.

Globally, 2019 is on its way to being one of the top five hottest years since record-keeping began in the late 19th century. And in part because of the hot weather in Europe, July may rank as the hottest month on record. June 2019 was already the hottest June to date.
The cause of this heat wave is a large area of high pressure, known as a “heat dome,” that has temporarily rerouted the typical flow of the jet stream and allowed hot air from Africa to surge northward. This weather feature is unusually intense, allowing for all-time temperature records to fall at the hottest time of year, when such records are usually so high they are difficult to topple.
The weather pattern responsible for this heat event is similar to the one that brought record heat to parts of Europe in late June into early July. However, this one is going to migrate northeast into Scandinavia, breaking records in Norway and Sweden late this weekend, and then it may go on to elevate temperatures across the Arctic Ocean, accelerating the melting of an already anemic sea ice cover.

The rising temperatures also heated up the political climate.
German news magazine Der Spiegel reported on a plan by the Green Party — which has become a major political force partially due to its push to decrease emissions and combat climate change — to prepare Germany for future heat waves. In its policy paper, Green Party officials propose a “right to home office” for all employees and a “right to be given the day off in case of excessively hot weather” for employees working outside.
The heat wave coincided with a visit of Swedish climate activist Greta Thunberg to France earlier this week. She addressed the National Assembly on Tuesday, delivering a speech that triggered calls for boycotts from right-wing politicians.

“You don’t have to listen to us,” Thunberg said in her address, “but you do have to listen to the science.”

A Giant 'Heat Dome' Over Europe Is Smashing Temperature Records, And It's on The Move

BY ANDREW FREEDMAN, THE WASHINGTON POST

JULY 25, 2019

A historic heat wave is bringing unprecedented temperatures to Western Europe, and is poised to expand northeastward to Scandinavia and into the Arctic by late this weekend.

Once above the Arctic Circle, the weather system responsible for this heat wave could accelerate the loss of sea ice, which is already running at a record lowfor this time of year.



First, residents of Paris, London, Brussels, Amsterdam, Munich, Zurich and other locations are suffering through dangerously high temperatures on Wednesday and Thursday.

Already on Wednesday, all-time national heat records in the Netherlands, Belgiumand Germany had fallen, right on the heels of a late June heat wave that broke similar records in France and other countries.

The German meteorological agency noted that Wednesday's national record of 104.9 degrees Fahrenheit (40.5 Celsius) may last just a day before being broken on Thursday.

It's difficult to beat all-time heat records in mid-July, considering this is the hottest time of year. It's even more unusual to beat these records by a large margin, which is what is occurring now.

For example, Paris is likely to exceed 100 degrees Fahrenheit (37.8 Celsius) on Wednesday by a few degrees, and break its all-time high temperature record of 104.7 degrees Fahrenheit (40.4 Celsius) by up to 3 degrees Fahrenheit on Thursday, with a forecast high of 108 Fahrenheit (42.2 Celsius).

The city's all-time high temperature record has stood since 1947.

Multiple all-time records were set elsewhere in France on Tuesday, both for daytime highs and hot nighttime low temperatures.



The UK Met Office is predicting that the country's all-time national heat record of 101.3 degrees Fahrenheit (38.5 Celsius) will be broken Thursday.

In addition, national heat records in Germany, where the mark to beat is 104.5 degrees Fahrenheit (40.3 degrees), could be set this week as well.

Heat of this intensity constitutes a significant public health threat, particularly for vulnerable populations like outdoor workers, the elderly, young children, those with compromised immune systems and anyone lacking the means to cool down.

In most of the cities currently affected, people lack air conditioning at home and in many public buildings and transit systems.


In London, where the record of 100.1 degrees Fahrenheit (37.8 Celsius) may be broken on Thursday, the subway system is not air conditioned throughout its network, leading some tube stations to see temperatures skyrocket well above 100 degrees Fahrenheit on platforms, and remain stifling aboard trains.

The average high in London for this time of year is 74 degrees Fahrenheit (23 Celsius).



The heat is the result of a massive area of high pressure, also referred to as a heat dome, that is forcing the jet stream to divert around, it like a large detour in the sky. This is drawing hot air northward from the Sahara Desert, and keeping cooler maritime air at bay.

The upper air weather pattern formed by this resembles the shape of the Greek letter Omega, and meteorologists refer to it as an Omega block, since such features can be slow to dislodge.

Eventually, the high pressure area responsible for this heat wave is forecast to slide northeastward and park itself over Scandinavia and migrate north into the Arctic. As it does so, it could set records for the intensity of the high pressure area so far north at this time of year, and is likely to lead to heat records in Sweden, Norway, and Finland.

Right now, Arctic sea ice extent is at the lowest level on record for this time of year. Weather conditions during the Arctic melt season are a crucial factor in determining whether ice extent hits a record low in September or just misses it, as the past few seasons have done.



A heat dome over the Arctic, following unusually mild conditions throughout much of the Arctic Ocean during the melt season so far, could ensure a new and ominous record will be set this year.

All weather is now occurring in an atmosphere that has been substantially altered by human activities, particularly the addition of large quantities of carbon dioxide, methane and other greenhouse gases from burning fossil fuels and land use change.

This has caused global average temperatures to increase by about 1.8 degrees since around the dawn of the industrial revolution, and in fact, 2019 is on its way to being one of the top 5 hottest years since instrument records began in the late 19th century.

Climate studies have consistently shownthat heat waves are becoming more common, severe and longer-lasting as the global average surface temperature warms. In other words, heat waves are now hotter than they used to be, making it easier to set all-time records.

The Met Office, for example, reports that the UK is now experiencing "higher maximum temperatures and longer warm spells" than it used to.

"The hottest day of the year for the most recent decade (2008-2017) has increased by 0.8°C above the 1961-1990 average. Warm spells have also more than doubled in length - increasing from 5.3 days in 1961-90 to over 13 days in the most recent decade (2008-2017). South East England has seen some of the most significant changes, with warm spells increasing from around six days in length (during 1961-1990) to over 18 days per year on average during the most recent decade," the Met Office stated in a research report.

A different study published earlier this year found a record-breaking summer heat wave in Japan during 2018 "could not have happened without human-induced global warming".

And a recent rapid attribution analysis, which has not yet been published in a peer-reviewed science journal, showed that the early summer heat wave in Europe was made at least five times more likely to occur in the current climate than if human-caused warming had not occurred.
