Summary
Recent weather patterns highlight the severe impact of climate change, with Europe experiencing unprecedented heat. A staggering 29,000 lightning strikes occurred in a single night, coinciding with record-breaking temperatures across the continent. The phenomenon known as a heat dome is trapping hot air, leading to dangerously high temperatures, particularly in the UK, where temperatures have soared into the high 30s Celsius. This extreme heat is exacerbated by high humidity, making it difficult for the body to cool down, especially for vulnerable populations.
The concept of tropical nights, where nighttime temperatures remain above 20 degrees Celsius, is becoming more common due to climate change, putting additional strain on health, particularly for the elderly and those with pre-existing conditions. Researchers indicate that such nights are now four to five times more likely, signaling a shift in climate patterns that were once considered rare. Historical comparisons show that the extremes of the past are now becoming the norm, with projections suggesting that temperatures could reach 45 degrees Celsius in the UK by mid-century if current trends continue.
Adaptation strategies are urgently needed as the UK is ill-prepared for these rising temperatures. Recommendations include installing air conditioning in hospitals and care homes by 2035 and in schools by 2050. Infrastructure, such as railway tracks and road surfaces, also requires reevaluation to withstand higher temperatures. The absence of regulations for maximum safe working temperatures further emphasizes the need for comprehensive changes to ensure public safety and health in the face of increasingly frequent heatwaves.
Show Notes
Continental Europe is in the grip of a deadly heatwave that has claimed hundreds of lives, including three children in France, as temperatures soared above 40C. France and Spain were among the worst affected as the continent sweltered under a heat dome, a vast area of stagnant high pressure. In Spain, 212 people have died due to the extreme heat over the past week, according to data from the country’s mortality monitoring system, MoMo. At least 48 people have drowned in France, seeking relief from the record-breaking temperatures, including a 21-year-old French footballer with a second-division club. In the UK meanwhile, the UK’s hottest June day on record has been broken again during this week's heatwave, with a provisional temperature of 36.4C recorded in Yeovilton, Somerset. This surpasses the high of 36.1C set on Wednesday in Gosport, Hampshire, the Met Office said. It comes after the Met Office extended its red warning for extreme heat for Friday as the peak of a heatwave affecting most of England and Wales are set to shift eastwards. But what is causing these records to be smashed, and this brutal weather to continue? And how long will the heat last? We explain the 'heat dome' that has descended upon Europe.

Could Donald Trump’s Republicans be heading for a major defeat in the 2026 US midterm elections? The latest polling numbers suggest they could be in trouble — and the consequences for Trump’s final two years as president could be significant. In this ITV News explainer, Jessica Taylor, Senate and Governors Editor at The Cook Political Report, breaks down the polls, political trends and key numbers that could determine the outcome of the US midterms on November 3. Donald Trump’s approval ratings have fallen sharply since he returned to the White House. Voters are increasingly unhappy with his handling of the economy, rising living costs and his immigration policies. Even traditionally Republican states could be competitive, raising the possibility that Democrats could win control of the House of Representatives, the Senate — or both. But how much can we really learn from the polls? And could history repeat itself?
There is a lot at stake in next week's election in Israel, not least the political future of Benjamin Netanyahu.
Manchester City are in big trouble, that much is clear. But how bad is the collateral damage for the Premier League? It has been just over a week since the Premier League confirmed that the club had been found guilty of massive breaches of the league's financial rules. It coincides with a period when City rose to be the dominant force in English football. The club maintain their innocence, and are appealing. But if the findings of the Premier League's independent commission are upheld, they could be in big trouble. ITV News Sports Editor has been taking a look at what the next stages are, the potential punishment for Manchester City, and how badly the league's reputation could be damaged.
For the past 25 years, Wales has radically reshaped its education system, taking a radically different path from England. But it remains far ehind every other home nation in performance in reading, maths and science, according to a new report. So what's behind these poor scores? It launched a play-based curriculum for young children, abolished school league tables, and scrapped tests like SATs traditionally held in primary school. Its new curriculum gives schools greater freedom over what they teach, aiming to develop critical thinking. But it has its critics, and the Programme for International Student Assessment (PISA) assessments don't make for pretty reading for the Welsh government. In the 2025 results, Wales was the lowest-performing UK nation, something that has happened in each of the tests since 2006, and the gap with England in particular is widening. We'll investigate why Wales is performing so poorly. Is it all down to the nation's alternative approach, or are there other factors at play?
Germany’s far-right, anti-immigration AfD party is on course for a major victory in the state of Saxony-Anhalt, potentially marking the first time a far-right party has led a government in Germany since World War II. With a campaign fronted by TikTok star Ulrich Siegmund, the AfD has surged in popularity, but it’s not without controversy. A win would likely send shockwaves through German politics and across Europe, heaping the pressure on Chancellor Friedrich Merz who is unpopular with voters. In this video, we break down the AfD's rise, look at their policies, and what a breakthrough victory could mean for Germany's future. Featuring an in-depth interview with British-German historian and journalist Katja Hoyer, we look at how Germany here and why the outcome is so important.
