City living: What can be done about London's overheating homes?
London is now considered one of the world's most extreme urban heat islands, according to the London Climate Ready capital's concrete jungle can result in the centre of the city being up to 10C warmer than surrounding rural means many homes become uncomfortable in the heat - unless measures are put in place to do something about it. As a musician, Andre Louis works a lot at his home in Kilburn and in summer, despite having numerous fans placed around the rooms, he says it gets unbearably hot. "The way that these places are built, they are built for warmth, but that means that in heat, it is doubly warm," he explains."We don't turn the heating on in the winter, for example. We haven't done in about eight years. In that time, we've actually saved a lot of money by not having to turn the heating on. "But because these places don't come with air conditioning, we find that anything we do to mitigate doesn't help." It's not just the houses that are heating up - it's the city itself. In heavily built-up parts of the city like Kilburn, the brick and concrete absorb the day's warmth and slowly release it after sunset. But down the road in Regent's Park, with its greenery and natural shade, it's several degrees cooler. At night, the difference between those built-up areas and greener ones can be up to 7C. London architect Sean Hill specialises in designing homes that need very little energy to keep them warm or cool. He says there are various aspects that can be taken into account when designing a home, including "the insulation of the building, the position and orientation of the building, the position of the windows [and] the size of the windows, in terms of overheating and as well as ventilating the space".His firm are working with couple Freya and Alex who recently bought a new home and want to introduce measures so that the space stays warm in the winter and cool in summer."We wanted to come in and kind of future-proof it, make it so that we thought it would be liveable for the next 20-plus years... so you don't get too hot or too cold," says Freya."That was our aim and because we're lucky enough to be able to do it all in one go at the beginning, we're going all out." Alex says when it is finished, the house will include various methods to keep it a comfortable temperature."When it's hot, the blinds will go down automatically. We have mechanical ventilation. The heat pump we have can run in reverse cycle, so we'll be able to cool the floors and the ceiling."He says they will also "paint the house white, so that will probably help some amount because we'll be reflecting more of the light."Hopefully all of those in combination will keep things at a cool temperature."The couple are avoiding using air conditioning as it often means pumping hot air outside, which can further increase temperatures in the our summers get warmer, the issue of how to keep cool is likely to get more people thinking about their options.

European wildfire smoke dampens UK heatwave with unusually hazy conditions
Smoke from wildfires in Southern Europe has brought hazy conditions to the UK, disrupting the current heatwave, forecasters have said. The UK experienced the fourth heatwave of the summer this week, with some areas seeing the mercury climb above 33C in the hottest places. However, the Met Office said "smoke from wildfires in Spain and Portugal, plus Saharan dust, has drifted over the UK'. This means the UK should expect "enhanced sunsets and sunrises in the coming days - deeper reds and oranges thanks to light scattering,' the forecaster added. Scientists say the phenomenon is linked to two processes known as Rayleigh scattering and Mie scattering. Rayleigh scattering, caused by tiny air molecules, normally makes the sky appear blue by scattering shorter wavelengths of light, such as violet and blue, according to the Royal Meteorological Society. But larger particles released by wildfires, such as soot and ash, trigger Mie scattering, which scatters all wavelengths more evenly and allows longer red and orange wavelengths to dominate. Met Office meteorologist Greg Dewhurst told Sky News the haze "will hang around for the next few days". The Met Office's forecast for Sunday says low clouds retreating towards the North Sea means there will be 'plenty of sunshine for most'. There will be strong winds in the South West of England, and it will remain warm along the eastern coast. Spain battled 14 major fires driven by high winds and aggravated by heat on Friday as authorities warned of "unfavourable conditions" to tackle flames that have already killed seven people and burned an area the size of London. Firefighters have been battling to put out blazes across southern Europe in one of the worst summers for wildfires in 20 years. An early two-week heatwave and southerly winds were worsening the situation in Spain, Virginia Barcones, director general of emergency services, said. Wildfires have burned more than 157,000 hectares in Spain so far this year, almost double the annual average, according to the European Union's Forest Fire Information Service. In neighbouring Portugal, meanwhile, thousands of firefighters were battling five large blazes in central and northern parts of the country, with one fire in Trancoso, some 350 km northeast of Lisbon, now raging for six days. Europe has been warming twice as fast as the global average since the 1980s, according to the EU's Copernicus Climate Change Service. The EU monitoring agency says that 2024 was the hottest year on record both globally and in Europe, which experienced its second-highest number of 'heat stress' days.

‘Unlike any other kind of fear': wildfires leave their mark across Spain
On Saturday, the people of Paüls will celebrate the feast of their patron saint, Sant Roc, with a mass, followed by a communal meal eaten at stone tables, jota folk dances and a profound and lingering sense of relief. Last month's wildfire – which turned the night skies a hellish orange, blackened the surrounding hills and devoured 3,300 hectares (8,154 acres) of land – was a near-disaster that stirred memories of the 2009 blaze in nearby Horta de Sant Joan that killed five firefighters. 'People were afraid that everything would burn and that they'd lose everything,' says Enric Adell, the mayor of the small Catalan mountain town. 'They were scared of getting trapped and not being able to get out of the village.' The fear of a fire like that, he adds, is unlike any other kind of fear. 'We've been through a pandemic and a nationwide power cut and torrential rains, but a fire on this scale was something else – as was the aftermath,' says Adell. In the hills above the village square, the charred trees are a reminder of what could have happened without the bravery of hundreds of firefighters, one of whom, Antonio Serrano, lost his life. Changing winds and sheer luck also played a part. 'When a fire hits,' says the mayor, 'it really leaves its mark.' This summer's fires have already left their mark across the length and breadth of Spain, from Galicia and Castilla y León in the north-west to Catalonia in the north-east, from the smart suburbs outside Madrid to Extremadura in the south-west, and all the way down to the beaches of Tarifa in Andalucía. As well as panic and the increasingly familiar tang of smoke, this year's fires have brought with them a sense of deja vu. The hot, deadly summer of 2022 yielded images that laid bare Spain's huge vulnerability as the effects of the climate emergency became increasingly plain. Footage that went around the world that July showed Ángel Martín, a 53-year-old man from Tábara in Castilla y León, using one of his excavators to try to stop the fires in the Sierra de la Culebra reaching the town. In the video, the machine is engulfed by the flames before Martín runs out of the inferno, the clothes burning off his frame. Martín, a much-loved figure in Tábara, suffered burns to 80% of his body and died in hospital three months later. Three years on, Spain is once again on the defensive. 'The fires are one of the parts of the impact of that climate change, which is why we have to do all we can when it comes to prevention,' the country's environment minister, Sara Aagesen, told Cadena Ser radio this week. 'Our country is especially vulnerable to climate change. We have resources now but, given that the scientific evidence and the general expectation point to it having an ever greater impact, we need to work to reinforce and professionalise those resources.' As politicians engage in blame games, experts warn, once again, that all the bickering over the number of water-dumping planes misses the point. The current spate of fires, they add, was entirely predictable and underlines the need for a fundamental rethink of land use and management in a continent that is on the frontline of the climate emergency. 'This year's fires are basically on the same level as those we saw in 2022 and 2023,' says Marc Castellnou, the head of forestry for the Catalan regional fire department and a fire analyst at the University of Lleida. 'Since 2017, we've seen this change towards more extreme fires … It's nothing new – and it's happening because climate change is bringing higher temperatures for much longer periods.' The dynamics are not hard to discern. If you have annual heatwaves that arrive one after the other – and last longer and longer – in a country where decades of rural depopulation have left huge areas of land untended, overgrown or given over to homogenous cultivation, then you will have massive fires that are getting harder to fight. As one Spanish scientist noted earlier this week: 'We have all the ingredients for the molotov cocktail we're seeing right now.' Cristina Montiel, a professor at Madrid's Complutense University and an expert in forest fires and land use, says that while Spain's firefighters and other emergency services are doing an 'extraordinarily magnificent' job that is keeping far greater disasters at bay, the problem lies with society as a whole. Despite the annual fires and the abundance of evidence, she says, 'it turns out that we are not – and we do not want to be – aware of the danger in which we're living'. If we were even a little aware, she adds, 'we would take the measures and decisions to protect ourselves'. Fifty years ago, says Montiel, most forest fires were intentional. But today's forest fires are increasingly caused by accidents or negligence and are spreading so voraciously because of two factors: landscape change and climate change. It is an explosive combination. This year's heavy spring rains led to an increase in plant growth that has now been dried out by successive heatwaves, leaving all that combustible vegetation, much of it in neglected areas, ready to serve as fuel for the fires. The situation is further complicated by the phenomenon of 'flash droughts', which can quickly dry out even well-irrigated agricultural land, and which are likely to become more common as global heating continues. Paüls is a case in point. Its population has dwindled over the decades and fewer and fewer people in the area work the land because of the shrinking economic rewards. 'If there were 100 people working the land before, now there are 30,' says Adell. 'If the same policies continue and things remain as hard as they are, then in a few years, there'll be almost no one.' Sign up to This is Europe The most pressing stories and debates for Europeans – from identity to economics to the environment after newsletter promotion All those years of abandonment had left ravines, gullies and pine forests overgrown and made them into temperature-activated timebombs. Last month's fire, says the mayor, was simply uncontrollable: 'We saw that there was no way of stopping it.' If there is much truth in the idea that preparation is all – and in the old maxim that 'fires are put out in winter' – the challenge now lies in undoing decades of neglect and bad planning that have seen the landscape forgotten and the appearance of housing developments in hazardous places. But Montiel cautions that the much-needed rethink will be neither quick nor easy. 'If things took a turn for the worse 50 years ago, we can now start changing them for the better,' she says. 'But you can't think that starting to change things now will pay off within two summers because that isn't true. These things are processes.' There are, however, already some signs that the message is getting through. After the Horta de Sant Joan fire 16 years ago, a group of shepherds approached the Catalan fire department to ask what they could do to prevent more blazes. The result was the Ramats de Foc (Fire Flocks) scheme, in which shepherds coordinate with firefighters to graze flocks of sheep and goats in areas with a high density of undergrowth and therefore high risk of fire. In areas cleared by the ruminants, firefighters have better access and, as there is less undergrowth, it is also easier to bring fires under control should they break out. 'We don't need more helicopters or firefighters,' says Marc Arcarons, who coordinates the initiative, which was launched in Girona in 2017 under the aegis of the not-for-profit Pau Costa Foundation. 'We could buy 200 more helicopters and it won't solve the problem. It's all about prevention and management.' The scheme also helps shepherds increase their existing incomes as those who participate can sell their meat or cheese at a premium as certified Ramats de Foc, so consumers know the produce is contributing to the preservation of the environment and the survival of traditional agriculture. About 120 shepherds have joined the project, which covers about 8,000 hectares (20,000 acres) in Catalonia. Similar schemes are planned or under way in the Canary Islands and Andalucía. Arcarons says that depopulation – and decreasing dependence on woodlands for building material and grazing since the 1960s – has caused what was once a patchwork of vineyards, olive groves and wheat fields to revert to dense forest. Fast-growing and highly flammable pines dominated, undergrowth flourished and this, combined with climate change and more frequent and longer periods of drought, has led to fires that are extremely difficult to control. 'It's like a chimney,' says Arcarons. 'If you keep throwing wood on the fire eventually the chimney will catch fire and the house will burn down.' Castellnou agrees that without adapting our landscapes to the realities of climate breakdown, we are sealing our fate. 'There's no point talking about more aeroplanes,' he says. 'If we limit our capacity for extinguishing fires by thinking we just need enough equipment to put them out then we're creating an unsustainable, artificial situation for summer after summer of extreme weather.'
