World will have to learn to live with heatwaves: UN
GENEVA - The world will have to learn to live with heatwaves, the United Nations' weather and climate agency said on July 1 , as much of Europe roasted in high summer temperatures.
The World Meteorological Organisation said that in future, people could expect heatwaves to occur more often and be more intense because of human-induced climate change.
WMO spokeswoman Clare Nullis said July was traditionally the hottest month of the year in the northern hemisphere, but it was exceptional, though not unprecedented, to have episodes of extreme heat this early in the summer.
She said extreme heat was 'widely called the silent killer', with the death toll often under-reflected in official statistics, compared to, for example, a tropical cyclone.
'It's important to stress that every single death from heat is unnecessary: We have the knowledge, we have the tools; we can save lives,' she added.
Western Europe is sweltering under the influence of a strong high pressure system, Ms Nullis told a press briefing in Geneva.
'This is trapping hot air from northern Africa over the region, and as we can see it's having a pretty big impact on the way we feel and the way we are acting,' she said.
A major factor in the heatwave is the exceptional sea surface temperatures in the Mediterranean.
'It's the equivalent of a land heatwave. The Mediterranean Sea is suffering a pretty extreme marine heatwave right now, and that tends to reinforce the extreme temperatures over land areas,' Ms Nullis said.
She said the urban heat island effect was exaggerating the situation in cities, with a lack of greenery to absorb the heat and concrete surfaces reflecting it.
The WMO said early warnings and coordinated action plans were crucial to protect public safety, and meteorologists were getting better at both.
'As a result of human-induced climate change, extreme heat is becoming more frequent, more intense. It's something we have to learn to live with,' Ms Nullis said.
She added: 'What can we expect in the future? More of the same, even worse.' AFP

Europe swelters as surprise early summer heatwave spreads
[PARIS] Nearly 2,000 schools were shut in France, monuments closed to tourists, and cities across Europe put on high alert as a record-breaking early summer heatwave spread across the continent Tuesday. Withering conditions that have baked southern Europe for days crept northward where such extremes are much rarer, with Paris on 'red alert' and warnings issued in Belgium, Switzerland and Germany. Tens of thousands of people have died in Europe during past heatwaves, prompting authorities to issue warnings for old and young, the sick, and others vulnerable to what experts call a 'silent killer'. On Tuesday, police in Spain said a two-year-old died in the country's north-east after being left in a car in the sun for several hours. The EU's Copernicus Climate Change Service (C3S) warned that millions of Europeans were exposed to high heat stress, and that temperatures would remain 'well above average' across most of the continent in coming days. 'This event is unusual because it's extreme, because it's very early on in the summer period, and climate change has almost certainly made it worse than it otherwise would have been,' climate scientist and C3S deputy director Samantha Burgess told AFP. A NEWSLETTER FOR YOU Friday, 12.30 pm ESG Insights An exclusive weekly report on the latest environmental, social and governance issues. Sign Up Sign Up Records have already tumbled, with the Netherlands experiencing its hottest opening day of July, France and Portugal their highest-ever single-day temperatures in June, and Spain and England their warmest June months. On Sunday, in a case of two extremes, the Mediterranean Sea hit a new June temperature record while Mont Blanc, the highest peak in Europe, went above freezing, a rarity for this time of year. 'Living like moles' The summit of the Eiffel Tower was shut for a second straight day while in Brussels the city's Atomium monument - famed for its giant stainless steel balls - was exceptionally shut as temperatures reached 37 deg C. Under scorching skies, Paris imposed its first 'red alert' in five years, empowering officials to limit or ban sporting events, festivals and school outings for children. The heat is expected to peak on Tuesday, with Paris facing highs of 38 deg C, but authorities have extended the alert into Wednesday. 'We're living a bit like moles,' Nicole, 85, told AFP in the stifling air of her apartment in a tower block in Paris. Some parks will remain open all night, pools have extended visiting hours, and cooling centres in churches and museums are offering respite from the lack of greenery and concrete surfaces that amplify the heat. Nearly 2,000 schools were closed at midday on Tuesday across France, according to the Ministry of Education, with teachers complaining that overheated and unventilated classrooms were making students unwell. Authorities are fanning out to check on the elderly, chronically ill and the homeless. 'When it's cold, I add blankets and hats. But when it's hot like this, what can I do?' said Jo, a 55-year-old homeless man in Bordeaux, in southwestern France. 'Unbearable' As far north as the Netherlands, some regions were on the second-highest alert Tuesday, with temperatures forecast to reach 38 deg C. 'I also live in a rooftop apartment, which means it gets insanely hot during the day, and it's unbearable,' student Liva Freimane told AFP in The Hague. Schools in Rotterdam and across West Brabant province adopted 'tropical schedules' to ensure students started and finished earlier to avoid the worst of the day's heat. In Germany, temperatures could peak at 40 deg C on Wednesday. In Spain and Portugal, where highs of 46 deg C were recorded in some locations over the weekend, a level of respite was expected, though temperatures could still exceed 40 deg C in parts. 'Extreme heat doesn't have to be a disaster: knowledge, preparedness and early action make all the difference,' said Tommaso Della Longa from the International Federation of Red Cross and Red Crescent Societies (IFRC), whose volunteers were fanning out across Europe. Burgess said European cities were adapting 'but not quick enough or extensive enough'. 'We're still seeing infrastructure challenges associated with heatwaves, pressure on national healthcare systems, and we still have excess deaths,' she said. Heat kills more people than hurricanes, floods, wildfires or any other climate-related extreme weather. A heatwave in 2022 killed an estimated 60,000 people across Europe, mostly elderly. The death toll from this 'silent killer' was under-reflected in official statistics, the World Meteorological Organization said on Tuesday. Spokeswoman Clare Nullis said society would have to adapt a harsher, hotter future. 'What can we expect in the future? More of the same, even worse,' Nullis said. AFP

Firefighters battle 3 blazes east of Los Angeles
Summer is typically the worst season for wildfires in California, as the atmosphere dries up and temperatures rise. PHOTO: AFP LOS ANGELES - Firefighters in Riverside County, east of Los Angeles, were battling three fires early in the morning on July 1 , even after the authorities lifted an evacuation order for thousands of residents. The blaze that prompted the order, the Juniper fire, began just before 11.30am local time on June 30 and swiftly burned almost 700 acres, according to Cal Fire, the state's firefighting agency. The order was issued in the afternoon and affected just over 5,000 residents, based on a New York Times analysis of the evacuation zones and LandScan population data. The order was lifted shortly before 9pm by Cal Fire. But only 30 per cent of the fire, which was burning in an unincorporated area about 112.6km south-east of central Los Angeles, had been contained. The cause of the Juniper fire was under investigation. Fire crews would continue working through the night to extinguish it, and evacuation warnings for the blaze, indicating a lower alert level, would remain in place overnight, Cal Fire said. A second blaze fire in Riverside County, the Wolf fire, began o n June 29 and had burned more than 2,400 acres by the ev ening of June 30 . The authorities reported that it was 30 per cent contained. Another blaze that began June 2 9, the Mindy fire, was mostly contained after burning about 100 acres, and all evacuation orders associated with it have been lifted. Summer is typically the worst season for wildfires in California, as the atmosphere dries up and temperatures rise. Though it can be difficult to predict wildfire activity, forecasters have already seen signs that this could be an especially intense year, with plenty of dry grass to fuel potential fires. In Southern California, conditions were especially dry this winter, setting the stage for more and larger fires this summer. By September, officials predict fire activity across most of the state will be above normal in 2025 . On average, about 1.4 million acres burn a year in California, but there have been varying totals in recent years. More than 4.3 million acres burned in 2020, when dry lightning – lightning without nearby rainfall – sparked an outbreak of wildfires across Northern California, but in 2022 and 2023, only about 300,000 acres burned each year. The Juniper fire started as residents of Los Angeles County were still reeling from devastating wildfires in January. The Eaton fire destroyed more than 9,400 structures, mostly in the community of Altadena in Los Angeles County, and burned about 14,000 acres. To the west, the Palisades fire destroyed more than 6,800 structures in Malibu and the Pacific Palisades neighbourhood of Los Angeles, and burned more than 23,000 acres. A total of 30 people died in the Eaton and Palisades fires, making the fire event the second-deadliest in California history. The Camp fire killed 85 people in Northern California in 2018, more than any other single wildfire in the state's history, according to Cal Fire.
