NI weather: Wildfire warning as heatwave hits
The organisation previously urged people to enjoy the weather responsibly during a similar wildfire warning in April.
High UV and pollen levels
While tens of thousands of people are expected enjoy the very warm spell during Twelfth demonstrations, the Tyrone and Donegal GAA semi-finals at Croke Park, and at beaches and parks, there are also alerts for high levels of UV and pollen, as well as a rise in pollution.Hay fever sufferers will have to endure high grass pollen levels until Sunday, with moderate weed pollen levels also forecast. Pollution levels are set to rise during the settled spell, with moderate levels expected in eastern areas on Saturday and Sunday, while protection from the harmful rays of the sun is also advised as high levels of UV are forecast.
Foyle Search and Rescue and the Belfast Coastguard have urged those cooling off at beaches and rivers to do so safely.The coastguard has also advised visiting life-guarded beaches and to be aware of local hazards
Heatwave conditions
Temperatures on Wednesday and Thursday reached 25C in parts of Northern Ireland and they are set to be higher in places on Friday, approaching 30C on Saturday and Sunday.For a heatwave to be declared temperatures must reach 25C or above for at least three consecutives days, according to the Met Office. The average maximum daytime temperature at this time of year is 18.6C in Northern Ireland.Other parts of the UK have different temperature thresholds to reach in the same amount of time, while in the Republic of Ireland a temperature of 25C must be recorded for at least five days, according to the Irish Meteorological Service, Met Éireann.
High temperature warnings have been issued across the Republic of Ireland, where daytime temperatures are forecast to exceed 27C by day, with overnight lows staying above 15C.The first warning, affecting 14 midland and eastern counties, comes into effect from midday on Friday until 06:00 local time on Saturday, with a second warning expanding to cover all of the Republic from midday on Saturday until 06:00 on Sunday.
Hosepipe bans
Water authorities in both Northern Ireland and the Republic of Ireland have urged members of the public to conserve water during the warm spell.NI Water are concerned that "high temperatures can create a huge demand surge" for water and have asked people to take steps to reduce water usage. On Thursday, Uisce Éireann in the Republic of Ireland issued an appeal to conserve amid an ongoing hosepipe ban in County Westmeath.The organisations are urging everyone to take steps such as using a watering can instead of hoses, shortening showers, and turning off taps while brushing teeth.

Overheated homes: why UK housing is dangerously unprepared for impact of climate crisis
Wondering what future British summers will be like, as the climate crisis unfolds? Clue: put away visions of sipping Yorkshire champagne on a Barcelona-style balcony. Think instead of stuffy, overheated homes making sleep impossible, droughts and floods that play havoc with infrastructure, and urgent health warnings for the old and very young. 'What we are facing is climate brutality. That is the reality of the hotter weather coming down the track,' says Simon McWhirter, the chief executive of the UK Green Building Council (UKGBC). Temperatures have already topped 40C during one summer, in 2022, and that record-breaking heat is likely to be repeated in the next 12 years, according to the Met Office, as global heating drives more weather extremes. A temperature of 28C inside the home is likely to become the norm in London and the south-east in the decades to come, according to McWhirter. Sweltering summers are more likely even when the sun isn't shining – muggy weather such as that of last month in many parts of the UK will be more common. Despite years of warnings, however, the UK is poorly prepared. The Climate Change Committee, the government's statutory adviser, has repeatedly highlighted a lack of urgent effort to adapt critical infrastructure, from water, transport and communication networks, to the fabric of our buildings. 'The way we are building new housing is not adequate to the climate change we are already seeing, never mind the even hotter weather that's coming,' says McWhirter. Part of this is owing to the construction of the homes themselves, which need good ventilation to create through airflow that cools rooms, with well-designed windows and external shutters, and reflective paint on roofs or outside surfaces. Homes should also be highly water-efficient, for instance being able to recycle bathwater to flush toilets or water gardens, to cope with the impacts of drought. Keeping cool also depends on the locality around a building, especially the shade and cooling impact of street trees. The UKGBC advocates a 3:30:300 approach: you should be able to see three trees from your dwelling; you should have 30% tree canopy cover in your neighbourhood; and you should be no more than 300 metres from a biodiverse green space or park. New rules aimed at overhauling how new homes are built have been promised for two decades. The first attempt was set out by Labour in 2008, only to be scrapped by the Conservatives in 2015, and years later a fresh attempt was mauled and delayed. This autumn, the 'future homes standard' (FHS) should finally be published, to come into force from 2027. But throughout this needlessly tortuous and expensive process, the focus has been mainly on how to keep draughty homes warm in winter, to stop them leaking heat – and money, and carbon dioxide alongside. The challenge of cooling overheated homes is new – and the current draft of the FHS fails to meet it, McWhirter says. 'The FHS does not address this threat properly,' he says. 'The focus has been on energy conservation and reducing bills. Absent has been the other side of the coin, which is climate impacts.' Fortunately, according to Steve Turner, the executive director of the Home Builders Federation, insulating homes to retain heat in winter also helps to keep heat out in summer. 'New-build homes are required to be exceptionally well insulated, which helps keep them stay both warmer in winter and cooler in summer,' he says. 'This makes living in a new-build more comfortable and significantly cheaper to run than older, less well insulated homes.' One obvious answer to overheating may seem to be air conditioning – it's common in hot countries, so why not here? Ministers are now considering subsidising the installation of air conditioning in the UK for the first time, a position the UKGBC supports. But that would be a controversial departure from climate policy. The boiler upgrade scheme offers households a substantial discount on the installation of air-source heat pumps, efficient electrical alternatives to gas boilers, in order to cut fossil fuel use and meet net zero targets. Up to now, only standard heat pumps have been eligible for the grants. Yet a form of technology exists that can heat and cool buildings: 'air to air' heat pumps, which rely on taking in air from outside and passing it through a heat exchanger to create hotter or cooler air that is pumped into the home. Sign up to Down to Earth The planet's most important stories. Get all the week's environment news - the good, the bad and the essential after newsletter promotion The problem is that air conditioning is extremely energy-intensive. The 'air to air' heating and cooling involved is much less efficient than 'wet' heating systems that heat water for radiators, so machines that can do both are a poor substitute for the efficient heat pumps needed for net zero, according to the HBF. Around the world, air conditioning requires such vast quantities of energy that the UN warned in July that the beneficial impacts of a massive surge in renewable power generation were being swamped by the vastly increasing demands of AI, datacentres and air con. The government intends that if air-to-air heat pumps are allowed, they should mostly be replacing current electric heating systems in small homes, particularly flats, where conventional heat pumps can be harder to install. This, the Department for Energy Security and Net Zero argues, could overall cut bills and energy consumption, as the increase in summer demand could be offset by winter savings. The government has commissioned further research and modelling on the issue. Even if the government's target of 1.5m new homes this parliament is achieved, newly built homes will still make up only a small fraction of the UK's housing stock. Changing existing homes will be far harder. Ensuring homes do not overheat is governed by Part O of the UK's building regulations, which came into force only in June 2022 – explaining why so many homes built even in the past few years are overheating. Part O applies only to new homes, though the government is considering whether it should be expanded to cover a change of use, such as offices converted to flats. At the moment, there are no substantial plans to retrofit the bulk of the UK's existing homes to stop overheating. A government spokesperson said: 'We know the importance of keeping homes cool in hot weather. That's why building regulations require new homes to be built to reduce the risk of overheating and through the future homes standard consultation we are exploring how to further improve protections. This is alongside considering the use of air-air heat pumps to keep existing homes cool under the boiler upgrade scheme.' If ministers wanted, they could also ensure that rented accommodation was brought up to decent standards on overheating. Without such enforcement, it will be up to individual householders – in which case, shutters and blinds should be top of the list, way ahead of any type of air con system.

UK weather: heat health warnings issued across England
Amber heat health warnings have been issued across swaths of England as temperatures rise. Parts of the UK are forecast to be hotter than Bali this week, with thermometer readings likely to hit the mid-30s celsius on Tuesday. The UK Health Security Agency (UKHSA) has issued heat health warnings for all of England. The East Midlands, West Midlands, east of England, London and the south-east have been upgraded to amber from 9am on Tuesday to 6pm on Wednesday. The south-west, Yorkshire and the Humber, the north-west and north-east have yellow warnings in place over the same period. The agency said the heat was likely to have a significant impact on health and social care services, including the potential for a rise in deaths, particularly among over-65s and people with health conditions. Forecasters have said consecutive days of high temperatures could lead to the UK hitting its fourth heatwave of the summer. The threshold is met when a location records at least three successive days with maximum temperatures exceeding a designated value, according to the Met Office. This is 25C for most of the UK but rises to 28C in London and the surrounding areas, where temperatures are typically higher. The hottest day of the year so far peaked at 34.7C, which was recorded at St James's Park in central London on 1 July. Dr Paul Coleman, a public health consultant at the UKHSA, said: 'These kind of temperatures can result in serious health outcomes across the population … so it is important that everyone takes sensible precautions while enjoying the sun. 'If you have friends, family or neighbours who are vulnerable, it is important to ensure they are aware of the forecasts and are following the necessary advice. Check in on them if you can to make sure they know that hot weather is on the way and how to keep themselves safe.' Human-caused climate breakdown is supercharging extreme weather across the world, driving more frequent and more deadly disasters including heatwaves, floods and wildfires. At least a dozen of the most serious events of the past decade would have been all but impossible without human-caused global heating.

Firefighters battle 'fire whirls' in northern Spain
CUBO DE BENAVENTE, Spain, Aug 11 (Reuters) - Extreme heat and strong winds caused "fire whirls" as a blaze burned several houses and forced the evacuation of hundreds of people from near a UNESCO-listed national park in northern Spain, authorities said on Monday. Thirteen fires broke out in the north of the Castile and Leon region, with about 700 people told to abandon their homes in half a dozen villages. Four fires were still live, Juan Carlos Suarez-Quinones, chief of environment for the regional government, said on Monday morning. Firefighters had extinguished the other nine. High temperatures on Sunday had caused the so-called fire whirls near Las Medallas park, forcing firemen to retreat and burning some houses in the nearby village, according to Suarez-Quinones. "This occurs when temperatures reach around 40 degrees Celsius (104 degrees Fahrenheit) in a very confined valley and then suddenly (the fire) enters a more open and oxygenated area. This produces a fireball, a fire whirl," he said. "This explosive and surprising phenomenon was very dangerous. It disrupted all the work that had been done, forcing us to start practically from scratch," he added. Scientists say the Mediterranean region's hotter, drier summers put it at high risk of wildfires. Once fires start, dry vegetation and strong winds can cause them to spread rapidly and burn out of control, sometimes provoking fire whirls. A prolonged heatwave in Spain continued on Monday with temperatures set to reach 42 C in some regions. Domingo Aparicio, 77, was evacuated to a nearby town from his home in Cubo de Benavente on Sunday after a warehouse in front of his home burned down. "How am I supposed to feel? It's always shocking for people close to the catastrophe," he said. Two or three fires may have been started by lightning strikes, Suarez-Quinones said, but there were indications that the majority were the result of arson, which he described as "environmental terrorism". In the northern part of neighbouring Portugal, nearly 700 firefighters were battling a blaze that started on Saturday in Trancoso, some 350 km (200 miles) northeast of Lisbon. So far this year about 52,000 hectares (200 square miles), or 0.6% of Portugal's total area, have burned, exceeding the 2006-2024 average for the same period by about 10,000 hectares, according to the European Forest Fire Information System. Firefighters were also battling blazes in Navarra in northeastern Spain and in Huelva in the southwest, authorities said.
