Europe was gripped by punishing heat waves in the summer of 2022, with wildfires, droughts and deaths highlighting what many around the world already know: Weather extremes can have devastating, real-world consequences.

When it comes to temperatures in warmer months, the direction of travel seems to be going one way.

The U.K.’s Met Office is projecting that summers in the country will be between 1 and 6 degrees Celsius warmer by 2070, and as much as 60% drier. It adds that global heat waves linked to climate change are likely to increase. Just this week it said last month was the U.K.’s hottest June on record.

The overall picture is challenging. In May 2023, the World Meteorological Organization said there’s “a 98% likelihood that at least one of the next five years, and the five-year period as a whole, will be the warmest on record.”

Sectors bearing the brunt

Fox and his co-authors are not alone in highlighting the difficulties of a hotter world.

In 2019, the International Labour Organization published a report which contained some sobering details.

“The economic losses due to heat stress at work were estimated at US$280 billion in 1995,” the U.N. agency said.

This, it added, “is projected to increase to US$2,400 billion in 2030, with the impact of heat stress being most pronounced in lower-middle- and low-income countries.”

The ILO’s report also highlighted which sectors would likely bear the brunt of rising average temperatures.

Those working in construction and agriculture, it said, were “expected to be the worst affected, accounting for 60 per cent and 19 per cent, respectively, of working hours lost to heat stress in 2030.”

Heat stress is a serious matter. The ILO describes it as referring to “heat received in excess of that which the body can tolerate without physiological impairment.”

Other outdoor jobs may be affected, too. In his interview with CNBC, Fox highlighted the potential challenges faced by workers in oil refineries, gas plants and chemical works.

All the above roles, he said, involve “quite a lot of external activity,” with workers also needing to wear personal protective equipment, or PPE, thanks to the nature of their job.

“This clothing can be quite cumbersome … and quite hot to wear, even under cold conditions,” Fox said.

That in turn makes employees “particularly at risk or vulnerable to … these sort of conditions.”

Factories are another area of concern. Fox noted that buildings of this type haven’t particularly been designed with heat ingress — especially extreme heat ingress — in mind.

“They’re full of equipment that’s generating a lot of heat, and it’s very difficult for factories, buildings, big warehouse buildings, to passively cool themselves,” he said.

Air conditioning is common in offices, but that’s not the case everywhere, he added.

Fox noted that office buildings in countries with temperate climates, like the U.K., “can get quite hot” because not a lot of air-conditioning had been installed.

Tackling the problem

The overall situation appears grave. For many, preparation and adaptation will be crucial.

The IMechE says this will involve “changes to the design of buildings, infrastructure and other physical assets and systems, both with regard to those that already exist and those that are yet to be built or manufactured, as well as the work, educational, leisure and other activities that humans undertake.”

In a statement issued alongside its report in April, the organization said it also wanted an urgent update to “guidance related to heat impacts on the workforce” so firms can come up with plans and enact changes in their working environments.

At the time, Laura Kent, the IMechE’s public affairs and policy advisor, referenced the challenges authorities face.

“We acknowledge that it would be difficult for the Health and Safety Executive to set a meaningful upper temperature limit due to variations between industries in both working conditions, required PPE and workload,” she said.

“However, HSE guidance needs to be updated to support sectors and industry in the development of appropriate strategies.”

The HSE did not respond to CNBC’s request for comment ahead of this story’s publication.

In other parts of the world, plans are being made to ban work when it’s too hot.

In May, for instance, Spain’s Minister of Labour and Social Economy, Yolanda Díaz, tweeted that carrying out “certain jobs during daylight hours” in extreme temperatures would be prohibited.

Speaking to reporters, Díaz said such prohibitions would take effect when AEMET, the State Meteorological Agency, issues red or orange weather alerts.

Citing Spain’s Labour Ministry, Reuters said the move would affect roles in sectors like agriculture and street cleaning. According to Reuters, in the summer of 2022 a street-sweeper in Madrid died from heatstroke.

Trade unions are also making their voice heard when it comes to working in extreme conditions.

Take Unite the Union, which has a presence in Britain and Ireland. It’s listed a range of advice provided by its health and safety representatives to both workers and employers.

Among other things, it stresses the importance of adequate ventilation for internal workspaces, the provision of cover for workers who are in direct sunlight, and stopping all work in extreme conditions.

Among a wide range of actions, Fox stressed the importance of design in creating safe and comfortable working environments in the face of hotter weather.

He said there needs to be a completely new approach to cooling that does not rely on the use of air conditioning, which has a significant environmental footprint.

“We need to explore … more traditional solutions of natural ventilation, use of shade, internal courtyards,” Fox said.

He noted that there’s “an awful lot” that can be done to prepare for the future. Raising awareness would be key. “In many cases, industries and workforces are just not aware that this challenge is coming, and are not preparing for it,” he said.

On top of that, identifying priorities in research and development and updating engineering methodologies and approaches would be needed.

Unless something is done, there will be, “in the coming years and decades, an increase in the economic impact of more extreme heat waves and just the general raising of the ambient seasonal temperature,” Fox warned.

New GM, Porsche and Honda EVs boost US sales: Here's a look at the top sellers in Q1

With new models rolling out from General Motors, Porsche, Honda, and several others, US EV sales increased by over 10% in the first three months of 2025. Nearly 300,000 EVs were sold in the first quarter of 2025. These were the top-selling models.

New EVs drive US sales growth in Q1 2025

Electric vehicle sales showed mixed results in the first quarter. Although Tesla is the center of attention as it continues to lose market share, several new EV models made an impressive debut.

With over 30,000 EVs sold in the first quarter, more than double the number sold last year, GM surpassed Ford and Hyundai Motor, placing second behind Tesla. GM’s Chevy is now the fastest-growing EV brand in the US, with the new electric Equinox, Blazer, and Silverado arriving.

GM sold 10,329 Chevy Equinox, 6,187 Blazer, and another 2,383 Silverado EVs in Q1. Thanks to its partnership with GM, Honda had an impressive sales quarter, selling over 14,000 EVs, including its luxury Acura brand.

According to Cox Automotive, Honda led EV sales growth for new entrants in Q1, followed by Acura, Jeep, and Dodge.

Jeep sold 2,595 Wagoneer S models during the quarter, its first electric SUV sold in the US. Dodge, another Stellantis-owned brand, sold 1,947 Charger EVs, or what it calls the world’s first electric muscle car.

Although Chevy’s Equinox EV made a statement in Q1, Ford’s Mustang Mach-E remained the top-selling non-Tesla with 11,607 models sold.

Rank	EV model	Q1 2025 sales
1	Tesla Model Y	64,051
2	Tesla Model 3	52,520
3	Ford Mustang Mach-E	11,607
4	Chevrolet Equinox EV	10,329
5	Honda Prologue	9,561
6	Hyundai IONIQ 5	8,611
7	Volkswagen ID.4	7,663
8	Ford F-150 Lightning	7,187
9	BMW i4	7,125
10	Tesla Cybertruck	6,406

After introducing the upgraded 2025 IONIQ 5 (which now has even more range and an NACS charging port), Hyundai sold 8,611 electric SUVs in Q1, an increase of 26% from last year.

Porsche had the highest EV sales volume growth after launching the electric Macan. With 3,339 units added, the Macan EV made up for Porsche Taycan sales falling 18% to just 1,019.

As Cox Automotive Analyst Stephanie Valdez Streaty noted, “The year certainly started strong, but the road ahead will be anything but smooth.”

Trump ending federal incentives and introducing new tariffs will “pose a monumental challenge for many automakers,” according to Valdez Streaty. Despite several new models arriving and significant incentives being offered (at least for now), the rest of 2025 “will likely be a volatile one for EV sales in the US.”

Electric concrete pump truck can drive 30 miles, pump 65 cubic yards [video]

Volvo and Putzmeister showcase unique battery-electric pump truck at Bauma

Based on a capable Volvo FM Electric 8×4 chassis, Putzmeister revealed one of the world’s largest all electric concrete pump trucks at the bauma equipment expo in Munich, Germany this week. The zero-emission concrete pumper can up to 50 km and pump approximately 50 cubic meters of concrete on a single charge.

50 km (a little over 30 miles) and 50 cubic meters (about 65 cubic yards) may not seem like impressive numbers, but consider this: a single cubic yard of concrete weighs a little over 4,000 lbs. (2 tons). A bit of simple math later, and you’ve got a quiet, vibration-free machine blasting (65 cu. yds ×4,100 lbs./yd = 266,500 lbs.) of construction material nearly 140 feet (42 meters) in the air.

That’s over 130 tons of construction material moved a really long way, and that’s (of course) without the use of diesel or gas.

“Volvo Trucks is the innovator when it comes to new technologies in combination with electric trucks. After presenting electric concrete mixers and heavy applications for mining, we are proud to show yet another world-class innovation for the construction segment here at bauma,” says Christoph Fitz, Head of Sales at Volvo Trucks in Germany. “With this electric pump truck, customers can have a zero-exhaust emission solution, low-noise operation and an efficient process thanks to the work-while-charging capacity.”

The Volvo FM Electric-based concrete pump is motivated by a pair of electric motors developing a continuous 330 kW (442 hp) of output through the company’s proprietary I-Shift gearbox. The truck’s four battery packs add up to 360 kWh of capacity, which can DC fast charge at speeds up to 250 kW or operate continuously (pumping even more material) with grid power or PU500 remote power connection.

Electrek’s Take

There will surely be a few nay-sayers who’ll try to cite the relatively short-sounding range of trucks like this, or the 100-ton Tadano mobile electric crane, but the range is typically more than enough to operate in urban environments and motivate the asset across even the largest job sites. Additionally, the ability to plug in to grid power and operate 24/7 makes all of that quieter, safer, cleaner … and moot.
