Monday briefing: The ‘toxic cocktail' of climate denial, federal cuts and the Texas floods
Good morning. The death toll from the catastrophic floods in Texas has climbed to 129, including at least 27 children and counsellors at Camp Mystic in Kerr County. With more than 160 people still missing, authorities warn that the number of casualties is likely to rise. On Sunday morning, some search operations were cancelled as heavy rain and strong winds battered the state once again. The flash floods, which swept through large parts of central Texas, are being described as one of the worst natural disasters in the state's history. At Camp Mystic, rain gauges recorded 6.5in (16.5cm) of rainfall in just 180 minutes. In addition to the human cost, the floods have caused widespread destruction. According to a preliminary estimate by private forecaster AccuWeather, the economic toll could range from $18bn to $22bn (£13.2bn to £16.2bn). The floods struck as the climate crisis worsens, and as the Trump administration's hollowing out of federal agencies has left critical services such as the National Weather Service under severe strain. The Federal Emergency Management Agency is also facing continued threats of defunding. Yet, despite the scale of devastation, there has been little public reckoning over climate breakdown or the erosion of essential public services. Instead, conspiracy theories have abounded. To understand how this catastrophe unfolded and the political response to it, I spoke to Oliver Milman, the Guardian US environment reporter. That's after the headlines. Israel-Gaza | An Israeli airstrike has killed at least 10 people, including six children, who were waiting to collect water in Gaza, Palestinian health officials have said. Dozens of others were killed in Gaza over the weekend in a separate strike that hit a home and a shooting near a food aid distribution site. Health | Health officials have urged people to come forward for the measles vaccine if they are not up to date with their shots after a child at Alder Hey children's hospital in Liverpool died from the disease. UK news | Charlotte Church, veteran peace campaigners, Trade unionists, activists and politicians, are among hundreds who have signed a letter describing the move to ban the group Palestine Action as 'a major assault on our freedoms'. Spain | Several people were hurt in a second night of anti-migrant unrest in the town of Torre Pacheco in south-east Spain after a pensioner was beaten up, authorities said. NHS | Health secretory Wes Streeting will meet representatives from the British Medical Association this week as he looks to avert five days of strikes by resident doctors. The devastating floods began in the early hours of 4 July, Independence Day in the US. Oliver Milman told me that what started out as a seemingly small storm stalled in an area where two rivers in central Texas meet, and dumped an enormous amount of rain. 'It caused the river to burst its banks, swept away homes, cars, flooded rivers and, most tragically, caught up on Camp Mystic,' Oliver said. 'There's still hope that some people could be rescued, but it's certainly going to be one of the biggest, deadliest natural disasters in recent US history.' Oliver said there are several factors that could explain why this flood was so devastating. We also get into the responses from elected officials and other players. How much of this is down to the climate crisis? As the planet gets hotter, mostly because of humans burning fossil fuels, the atmosphere is able to hold more moisture. One meteorologist told Oliver that the Earth's atmosphere is now like a giant sponge. 'You've got more moisture in the atmosphere, and more energy because it's getting hotter, and therefore you're getting more of these extreme precipitation events happening in several places around the world, including parts of the eastern US. But the western half of the US seems to be getting more drought,' Oliver said. 'So, very crudely speaking, half the country's not getting enough rain, and the other half is getting too much in these intense downpours.' He pointed to some interesting statistics from the Environment Protection Agency: of the 10 heaviest precipitation single-day events in US history going back to 1910, nine have happened since 1995. 'We're clearly getting more and more of these events. There's been research done showing they're becoming more common in Texas and will continue to as the world heats up,' Oliver added. The geography of central Texas also made the floods more catastrophic. 'It's hilly and has these canyons, lots of rivers, and not much topsoil. So when rain hits, it flies off the ground very quickly. It's known as 'Flash Flood Alley' in some places, so that was a factor. The rain hit, and the devastation followed.' What impact have Donald Trump's cuts had? The other factor, which Oliver likened to a toxic cocktail, is the political situation in the US. 'The Trump administration has essentially tried to gut the federal workforce: firing scientists, firing weather forecasters, trying to eliminate large sections of the scientific agencies that deal with climate change. So you had a situation where a lot of National Weather Service offices, which track storms and issue warnings, were critically understaffed,' Oliver explained. Democrats have called for an investigation into whether the sweeping cuts introduced by the Department of Government Efficiency (Doge), once led by Elon Musk, played any role in the disaster. The Trump administration has dismissed any suggestion that its policies had an impact. 'The Trump administration has pushed back quite hard and said this was an act of God, there were adequate resources, and so on,' Oliver said. Yet, understaffing was an issue and there was a disconnect between the meteorologists issuing warnings and the emergency services, he said. 'The National Weather Service issued a warning about dangerous flood conditions at 1.14am [on 4 July], but there wasn't – and it's still unclear why – coordination with emergency services to evacuate people, to mobilise resources in enough time. A lot of people are pointing fingers at the cuts Trump has made to the coordination services usually handled by the federal government.' And it's not just Trump that people are focusing on. The week before the floods, Texas senator Ted Cruz, ensured that the 'big, beautiful bill', a Republican spending bill pushed through and signed by Trump on Independence Day, would include particular cuts. 'It does a lot of things: cuts the social safety net, people lose health care, gives tax breaks to the wealthy, removes food assistance, guts support for clean energy,' Oliver said. 'But one thing it also did was remove a $150m fund to improve weather forecasting at the National Oceanic and Atmospheric Administration. Cruz personally inserted the language to cut that and then, tragically, just days later this storm hit his home state and killed many people. So there are a lot of questions being asked about his role and whether those cuts played a significant role.' Republicans have largely fallen into line on the Texas floods, lavishing praise on Trump, while avoiding questions around the effect of Doge. Has this moved the dial on the climate emergency? In Texas, the reaction on the ground has been one of disbelief and devastation, Oliver said. 'There's a lot of 'thoughts and prayers' rhetoric in Texas right now, a sense of rallying to help those in need. People are mainly stunned rather than immediately pointing fingers, although local officials are raising questions about how much warning they got from the National Weather Service. There are also concerns about the local government's actions. There had been a plan to install an early-warning flood system along the river, but the idea was ditched because it was considered too expensive. So you've got this local angle, too.' Far-right players have descended on central Texas in a stunt they claim is part of a 'disaster relief' effort. In a video posted by one group, they say their so-called 'activists' are distributing supplies to survivors, but make clear that they are prioritising 'their people' and 'European peoples' in those operations. As is now common when disaster strikes, conspiracy theories are being spread, Oliver said, by rightwing influencers and elected representatives such as Marjorie Taylor Greene. 'They have questioned the cause [of the flood], whether it's weather modification, cloud seeding, some nefarious machine. There's this irony: we are modifying the weather – it's called climate change. But it's not the kind of weather modification they're talking about.'

'People are now able to live in their own realities, sealed off from facts,' he said. 'Whatever people believed before the storm, the storm just reinforced it. That's become a recurring theme, not just in disasters but in politics more broadly. People are very entrenched here. I know that's also an issue in the UK and Europe, but in the US things feel paralysed. I don't know if this will move anyone's opinion.'

Doctor warns about the huge mistake millions make in the car every day: 'Your brain slows down'
A doctor has shocked millions of drivers after revealing that a common setting in your car could be quietly sabotaging your brain function. Dr Clay Moss has racked up more than 6.9million views on a video after issuing a blunt warning about the recirculation button - a familiar feature most drivers flick on without a second thought. 'Did you know there's a single button in your car that could be causing more harm than good?' the American expert began in the eye-opening video. 'You guys remember this little guy right here that we always love putting on?' he said, pointing to the well-known recirculation symbol, which is typically found on the dashboard near the air conditioning controls. 'That little recirculation symbol stops outside air from getting in, which is great when you're trying to quickly cool off the air on a hot day, but it can have unintended consequences over time,' he explained. It's not just smog it's stopping, it's your the brain from functioning at its best, too. While many hit the button to block pollution or get cool air flowing fast, Dr Moss says keeping the car in recirculation mode for too long can quietly poison the air inside. 'You see, when you're breathing in a sealed car, carbon dioxide builds up pretty quickly. Thirty minutes of recirculation and you could easily exceed 12,000 PPM [parts per million] of CO2, where your brain literally starts to slow down.' View this post on Instagram A post shared by Clay Moss, MD (@drclaymoss) With two or three passengers, the issue gets worse: 'You could easily hit 2500–3000ppm of carbon dioxide. That's when you start to get drowsy, foggy and irritable.' And he's not just talking hypothetically. In a 2018 study on U.S. driving conditions, the levels of carbon dioxide recorded were alarming. It found that under recirculation mode, even single-occupant drives can reach up to 2,500ppm in longer or multi-occupant trips, well above cognitive risk thresholds. According to Dr Moss, that's where cognitive performance drops, reaction time slows, and you're more prone to drowsiness and brain fog. Before you panic, Dr Moss says there's an easy hack that takes just seconds and could make a massive difference to your alertness behind the wheel. 'Now, the fix is super easy,' he said. 'You just either crack the window, or switch to the fresh air mode and turn off the recirculation mode for just two minutes. It flushes the CO2 out and keeps your brain sharp.' 'Your car's climate settings aren't just about comfort, they mess with your cognition too,' he added. 'So breathe better, drive safe.' The clip has sparked major debate online, with many drivers admitting they had no idea something so minor could affect their brain so dramatically. 'I drive to work two hours each way every day… is this why I get so sleepy by the time I get to my destination?' one person commented. 'I've actually never used it to cool off, but I've used it when driving through stuff that I don't want getting in my car (like truck exhaust, dust, dirt, grass, etc),' said another. 'Is that why I suffer from road rage?' Another joked. Others pointed out they use it 'all the time to avoid city smog,' while some confessed that they've never switched it off. However, in a silver lining, more modern cars have an automatic recirculation mode that have timers to effectively shut-off by themselves to keep drivers safe.

Forget Ozempic and Mounjaro, this firm is on the edge of a weight-loss breakthrough
Questor is The Telegraph's stock-picking column, helping you decode the markets and offering insights on where to invest. This year, drug companies have been living under a cloud of uncertainty created by the Trump administration. Threats of tough action on drug pricing and tariffs have fuelled nervousness, while recently agreed cuts to Medicaid in the 'big beautiful bill' are also causing concern. But medicine will always be a priority for the sick, and innovations from the pharmaceutical industry are vital for creating healthier societies as populations age. Biotech giant Amgen looks particularly well placed to weather current uncertainties and prosper from the long-term prospects of its industry. A first-class dividend record, which includes increased payouts in each of the last 13 years, is testament to the resilience of the business. Key to this is that unlike many rivals, no one product dominates Amgen's $33.4bn (£24.7bn) of sales. In fact, the company boasts 14 blockbuster drugs with over $1bn sales each. This product diversity means that while its biggest selling treatment – an osteoporosis drug called Prolia that generated $4.4bn revenues last year – is expected to see rapid declines following its loss of patent protection in February, the company's top line is forecast to grow. The drugs Amgen sells cover a number of different areas, including cancer, cardiovascular disease, osteoporosis and rare diseases. Recent trading has been strong, too, with 21 drugs reporting record sales last year and 14 reporting double-digit growth. Amgen is experiencing particularly strong growth from cholesterol drug Repatha, which is forecast to net $2.8bn this year, and osteoporosis treatment Evenity, both of which target underserved patient groups. Sales are also soaring for cancer drug Blincyto. In terms of the problems posed by Trump, Amgen looks well placed. Tariffs should not be a major issue given it mostly manufactures in the US, where it is currently increasing capacity. Having just opened a new facility in Ohio, it plans to plough another $900m into growth in the state and a further $1bn is being spent building in North Carolina. Much of this spending is aimed at increasing production of biosimilars, which are lower cost versions of existing drugs that have lost patent protection. This focus should help position the group to deal with the US government's drug-pricing agenda because biosimilars help lower healthcare costs. Amgen has said Medicaid cuts could have a material adverse impact on some drug sales, however, the cuts passed in the big beautiful bill last week were scaled back in order to get it approved. Reassurance about prospects can also be taken from the number of top fund managers backing the stock – all among the best-performing 3pc globally according to financial publisher Citywire. A total of 14 of these individuals back the shares. The level of smart-money backing has won Amgen a place in Citywire's Global Elite Companies index, which is home to the 76 very best ideas from among the c.6,000 stocks held across the portfolios of the top managers Citywire tracks. For these backers, the potential of Amgen's drug development is a key part of its attraction. Investors have been particularly excited about a long-lasting obesity drug Amgen has begun late-stage phase III trials for, called MariTide. It produces similar levels of weight-loss as Wegovy and Zepbound, which are multibillion-dollar treatments made by Novo Nordisk and Eli Lilly respectively, but MariTide only needs to be injected once a month or less, compared with weekly for the existing drugs. While the potential is exciting, the market reacted negatively to recent news of high levels of nausea during early use. Amgen reckons it can address this by starting patients on lower doses. Better trial news has recently come from cancer treatments, specifically a stomach cancer drug called Bemarituzumab. Amgen is also looking to extend the uses of some of its existing blockbuster medicines. The company put a record $6bn into research and development last year pursuing new opportunities, which represented more than 18pc of sales and a 25pc increase on 2023. While Amgen's margins have nudged down over recent years, it is nevertheless highly profitable. It reported 46.9pc underlying operating margins last year. Meanwhile, solid earnings per share growth is predicted over the next two years of just over 4pc on an annualised basis. That looks an attractive package with the shares priced at 14 times forecast earnings and yielding 3.4pc, especially once the potential for positive surprises from the busy development pipeline is factored in. British buyers of the shares need to fill out the correct paperwork to minimise withholding taxes and check for any extra dealing costs with brokers. Questor says: buy Ticker: NYSE:AMGN
