UK schools and offices not equipped for impact of global heating, report warns
The UK's schools, care homes and offices are not equipped for the effects of global heating and face lengthy heatwaves even in optimistic scenarios, according to a groundbreaking report that calls for climate resilience to be declared a national emergency.
The report by the UK Green Building Council also predicts that towns including Peterborough and Fairbourne will be uninhabitable by the end of the century because of flooding.
Produced over two years, the roadmap sets out a blueprint for action and warns that without the adaptation of millions of buildings, there will be increased injury, health impacts, deaths and untold economic damage.
Five key threats are examined by the roadmap: overheating, wildfires, flooding, drought and storms.
Detailed thermodynamic modelling on school buildings reveals that schools across London and the south-east will face 10 weeks of extreme heat a year – defined as 28C and above – in a low-warming scenario, defined as 2C above preindustrial levels. The world is on track for 2.7C of heating.
The roadmap modelling warns that 6m houses and flats in London and the south-east will face three weeks above 28C a year in the same low-warming scenario, causing economic damage from reduced productivity of employees, and health threats to vulnerable and older people.
Care homes in London and the south-east, where residents are extremely vulnerable, will be face temperatures above 28C for four weeks a year in the low-warming scenario, the roadmap predicts.
Ordinary offices where the productivity of millions of workers is key to economic growth, are also woefully underprepared for the onslaught of extreme weather now and in the years to come, the report says. The modelling says modern buildings are more vulnerable to overheating than older ones because they have larger areas of glass and are of a more lightweight construction.
Adaptation measures for buildings could include the use of solar shading and replacing regular glass with solar glass. So-called passive adaptation is recommended before things such as air conditioning, which increase energy usage and emissions.
'It is within our power to design buildings and cities that are safer, more comfortable and resilient to the impacts of the changing climate, and it is vitally important that we act now to do so,' the roadmap says.
The report, which is launched on Thursday, calls for:
The appointment of a minister for resilience within the Cabinet Office
A new legal objective to ensure all planning decisions deliver climate safety.
A more ambitious future homes standard to protect against increasing climate hazards – overheating, flooding and water scarcity.
A comprehensive retrofit strategy to make homes and buildings climate safe.
The protection of all communities with trees, parks and ponds.

The government's new planning and infrastructure bill does not include a mandate to make buildings climate safe from overheating, flooding, wildfires or droughts. It has been criticised for placing too much emphasis on growth rather than the green environment.
London tops a list of the cities and towns most vulnerable to wildfires, drought and flooding, with Birmingham and Manchester second and third most at risk, according to the analysis.
The flood impact on the town of Peterborough will make it uninhabitable by the end of the century, the analysis says. In Wales, the town of Fairbourne, which sits between Snowdon (Yr Wyddfa) and the Irish Sea, will also be uninhabitable as a result of flooding and sea-level rises.
Simon McWhirter, the chief executive of the UK Green Building Council, said the roadmap starkly illustrated the threats of a changing climate and said the response could not be delayed.
Calling for the appointment of a minister for resilience within the Cabinet Office, he said: 'The UK is not ready for the extreme weather events of today, even less so for the hotter, wetter and wilder climate that is already racing down the track at us. Our homes, schools, hospitals, parks and offices are on the frontline, protecting and nurturing us. We need a fundamental rethink … if we are to help protect people and our way of life.'

Amber heat health alert issued with temperatures set to reach 30C over weekend
A second amber heat health alert has been issued in as many weeks, with temperatures again set to pass 30C over the weekend. The alert, which covers London, the East Midlands, South East, South West and East of England, starts at midday on Friday and will last until 6pm on Tuesday. The UK Health Security Agency (UKHSA) also issued a yellow alert for Yorkshire and Humber and the West Midlands for the same time period, with the agency warning of significant impacts across health and social care services. It comes as unsettled conditions on Thursday and Friday will still see temperatures steadily rise, with highs potentially reaching 28C in the south and east by Friday. Temperatures are expected to peak on Monday when much of the country will see temperatures in the early to mid-30s, the UKHSA said. An amber alert was previously issued for all regions in England on June 19, the first time it had been used since September 2023. On the same day the UK recorded its warmest day of the year so far, with temperatures reaching 32.2C in Kew, west London, before heatwaves were declared across England and Wales. An official heatwave is recorded when areas reach a certain temperature for three consecutive days, with thresholds varying from 25C to 28C in different parts of the UK. Dr Agostinho Sousa, head of extreme events and health protection at the UKHSA, said: 'We have already seen a spell of hot weather last week and temperatures are once again set to increase in the coming days, with central, southern and eastern areas of the country likely to see the biggest impacts. 'Our findings show that heat, especially at the sort of temperatures we are likely to see at the beginning of next week, can result in serious health outcomes across the population, especially for older adults or those with pre-existing health conditions. 'It is therefore important to check on friends, family and neighbours who are more vulnerable and to take sensible precautions while enjoying the sun.' Thunderstorms are possible with warm, humid air set to linger in the south and east on Thursday, with maximum temperatures of 27C in eastern England, the Met Office said. But temperatures are unlikely to feel 'quite as muggy', meteorologist Honor Criswick said. 'For the first part of the day, it is set to be unsettled (with) outbreaks of quite heavy rain at times, particularly across Scotland,' he said. 'But it's fairly fast moving, so by the time we reach the afternoon, particularly from the west, we're going to see the return of those bright and sunny spells. 'And behind this area of rain, a much fresher feel to the air as well.' On Friday, forecasters said the unsettled conditions look set to continue. According to the Met Office, rain could be heavy in the west, while the east of England could remain dry, escaping with some sunny intervals. Parts of the south and east may also remain very warm, with highs potentially reaching 28C as the muggy air returns. Ms Criswick said: 'For the rest of the week, we do have a ridge of high pressure building to the south, so once again pushing in a return of that warmer air. 'So, that fresher feeling day as we head into Thursday, it's going to be quite a brief interlude. 'And low pressure is never too far behind, so still some rain on the cards to finish off the week and as we head into the weekend.' The National Pharmacy Association (NPA) has advised patients to store their medicine away from heat zones and direct sunlight, warning that they can lose effectiveness or cause unwanted side effects. Vice-chairwoman and pharmacist Sukhi Basra said: 'It's important we take sensible precautions, including double-checking that your medication is stored correctly in a cool dry place, as per any storage instructions, ideally below 25C, as well drinking plenty of fluids and keeping your homes cool in the hottest hours of the day. 'We know the hot weather can be more of a challenge for older people or those with certain health conditions and it's important people check on vulnerable friends, family and neighbours during this period. 'If anyone has concerns at all about their health or their medication, please speak to your local pharmacy, who will be well placed to help.'

Heat alerts issued for most of England as temperatures above 30C forecast again
An amber heat-health alert has been issued for much of England, with temperatures expected to rise above 30C (86F) over the weekend. The alert, issued by the UK Health Security Agency (UKHSA), covers London, the East Midlands, and the south-west, south-east and east of England. It is due to come into force at midday on Friday and will remain in place until 6pm on Tuesday. A yellow alert has also been issued for Yorkshire and the Humber, and the West Midlands. The UKHSA warned that the prolonged heat could have a significant impact on health and social care services. It follows a previous amber alert issued on 19 June, when temperatures hit 32.2C in Kew, west London, prompting official heatwave declarations across England and Wales. The latest warnings come as parts of eastern England are forecast to reach 27C on Thursday, with thunderstorms possible in the south and east as a result of lingering warm, humid air. The Met Office meteorologist Honor Criswick said: 'For the first part of the day, it is set to be unsettled, [with] outbreaks of quite heavy rain at times, particularly across Scotland. 'But it's fairly fast moving, so by the time we reach the afternoon, particularly from the west, we're going to see the return of those bright and sunny spells. 'And behind this area of rain, a much fresher feel to the air as well.' Temperatures are expected to climb again before the weekend, with highs of up to 28C in southern and eastern parts of the country expected by Friday, while western regions may have some heavy rain, and the east could remain dry with sunny spells. But Criswick warned that 'low pressure is never too far behind', with 'some rain on the cards to finish off the week and as we head into the weekend'. Scientists say the climate crisis is making heatwaves more frequent and intense, especially during the early part of summer.

Mapped: Where second heatwave will hit as temperatures set to soar to 32C
Britons are set to bask in another heatwave as temperatures rise to 30C this weekend and get even hotter into next week. Unsettled conditions on Thursday and Friday will still see temperatures steadily rise, with highs potentially reaching 28C in the south and east by Friday, the Met Office said. Thunderstorms are possible with warm, humid air set to linger in the south and east on Thursday, with maximum temperatures of 27C in eastern England, the forecaster added. But temperatures are unlikely to feel 'quite as muggy', meteorologist Honor Criswick said. 'For the first part of the day, it is set to be unsettled (with) outbreaks of quite heavy rain at times, particularly across Scotland,' he said. 'But it's fairly fast moving, so by the time we reach the afternoon, particularly from the west, we're going to see the return of those bright and sunny spells.

According to the Met Office, rain could be heavy in the west, while the east of England could remain dry, escaping with some sunny intervals. Parts of the south and east may also remain very warm, with highs potentially reaching 28C as the muggy air returns. Temperatures are expected to peak on Monday when much of the country will see temperatures in the early to mid-30s, the UK Health Security Agency said. It comes as the UKHSA issued an amber heat health alert, covering London, the East Midlands, South East, South West and East of England. It is in place from midday on Friday and will last until 6pm on Tuesday. The UK Health Security Agency (UKHSA) also issued a yellow alert for Yorkshire and Humber and the West Midlands for the same time period, with the agency warning of significant impacts across health and social care services. Going into next week, a low pressure system passes to the north west of the UK on Monday bringing wetter windier conditions to the region. There will be dry and hot weather elsewhere across the country with temperatures reaching 32C in London and the south east, the Met Office forecast shows. Dr Akshay Deoras, a research scientist in the department of meteorology, University of Reading, urged people to 'treat extreme heat with the same respect you'd show a dangerous storm.' He advised against going outdoors during the hottest part of the day and stressed the importance of staying hydrated – drinking water regularly, even without feeling thirsty, and avoiding alcohol, which 'can accelerate dehydration.' To stay cool, he recommended wearing loose, light-coloured clothing and using a wide-brimmed hat when outside. People were also urged not to brush off symptoms such as dizziness, nausea, rapid heartbeat or headaches. 'These warning signs can rapidly escalate into life-threatening heatstroke if ignored,' he said. Anyone experiencing these symptoms should move to a cooler area, remove excess clothing and apply cold water to the skin, he added.
