Is the UK really ahead in cutting carbon emissions?

The UK Prime Minister has announced several changes to key policies designed to help Britain reach net zero by 2050. In a major speech justifying what many see as a watering down of commitments, Rishi Sunak championed Britain’s achievements to date in cutting emissions. But where does the UK actually stand compared to other countries? Tim Harford talks to Hannah Ritchie from Our World in Data and author of “Not the End of the World”.

NHS consultants in England are striking over a pay offer of 6%. We look at whether they are paid an average of £120,000 a year and examine how much their pay compared to inflation has fallen. Also we fact check some of the claims Rishi Sunak made in his net zero speech, ask whether Britain is really that bad at building infrastructure compared to other countries and investigate the real levels of cancellations at Scotland and the UK's largest ferry company, Calmac. ...

Social housing, NHS workforce and Liz Truss debt claims

Long: Housing minister Rachel Maclean claimed the government has built a record number of social rent homes. Tim and the team investigate. Following Lucy Letby’s conviction, we look at how sentences for murder have changed over the past few decades. Plus after Liz Truss’s speech this week defending her short stint as Prime Minister, Tim reminds us how her mini-budget raised borrowing costs and might have pushed up the national debt even more. And will 1 in 11 workers in England really work for the NHS by the middle of the next decade?

Skin cancer, London rents and your great great great granddaughter

A BBC report quoted a study that said 1 in 4 men and 1 in 5 women in the UK will get skin cancer in their lifetime. Tim Harford and the team look into the detail. Also London’s Mayor Sadiq Khan said London’s average rent will hit £2,700 a month next year, with the average take home salary £2,131. How accurate are the figures and what do they tell us about the affordability of the capital’s rental properties? We fact check Donald Trump’s recent claim that 35,000 Americans died building the Panama Canal. And as noughties band Busted re-release Year 3000 with the Jonas Brothers, just how many greats should be in front of “granddaughter” in that famous lyric? ... Read more

Did 35,000 Americans die building the Panama Canal?

The construction of the Panama Canal linking the Atlantic and Pacific Oceans through Central America is considered one of the greatest engineering feats of all time. It also caused enormous human suffering and loss of life. Donald Trump claimed in a recent interview that 35,000 Americans died in the canal’s construction. But is that true? Tim Harford finds out, with the help of Matthew Parker, author of Hell’s Gorge: The Battle to Build the Panama Canal.

Covid deaths, North Sea gas and Chloe Kelly's World Cup penalty

Covid related deaths are rising in England and Wales - but what do the figures really tell us? Also the UK's GDP during the pandemic has been revised upwards. Tim Harford and team ask why and discuss what it tells us about the UK's economic performance compared to other countries. Is North Sea gas really four times cleaner than gas from abroad? It's a claim recently made by the government. And we ask whether Chloe Kelly's penalty shot at the World Cup was really faster than the Premier League's fastest goal last season.

What percentage of our brain do we actually use?

On this week’s episode of More or Less we interrogate a widely circulated myth relating to how much of our brain power we can access and engage. Ever heard someone say, “You know we can only use 10% of our brains, right?”. Well, they’re wrong. It’s the stuff of make believe and far-fetched movie plots. Science and evidence based research tells us so - and has, it turns out, been telling us so for decades…politely, if impatiently. So, then, if not 10%…what percentage of our brain do we actually use? From dark matter neurons to super-highway synapse and ghost cells that serve as inert echoes of our evolutionary past - with the help of two leading experts in the field, we crack open the figurative cranium of this debate and rummage around for the definitive truth.

HS2 and electric cars, UK vs China emissions & massive maths errors

Can you really buy an electric car for everybody in the UK for the cost of HS2? That claim was recently made on Radio 4's Broadcasting House programme. Also we look at a viral claim that 1 in 73 people who received the Covid vaccine in England was dead by May 2022. Plus we look at the size of the UK's carbon emissions when compared with China and talk about how a recent More or Less maths error pales in comparison to one in the Guardian.

How safe is the release of Fukushima nuclear plant water?

Water used to cool nuclear reactors at the stricken Fukushima nuclear power plant in Japan is being released into the Pacific Ocean by Japanese authorities. The move has sparked protests and concerns about safety in the region and met with retaliation from near neighbour China. But how safe is the water that’s been released? Presenter Charlotte McDonald and reporter Calum Grewar investigate, with the help of Professor Jim Smith of the University of Portsmouth and Professor Gerry Thomas, formerly of Imperial College London and the Chernobyl Tissue Bank.

How many butterflies are there in the world?

Butterflies are a much-loved feature of summer in many parts of the world. But how many of them are there on Earth? That’s the question a young listener to More or Less wanted an answer to – and she couldn’t find the answer no matter how hard she searched the internet. Presenter Daniel Gordon enlists Professor Jane Hill, a butterfly expert at York University, England, who’s also President of the Royal Entomological Society, to try and help solve the mystery. He also consults Holly Mynott, International Officer of Butterfly Conservation, who describes the techniques used to run The Big Butterfly Count in the UK – the biggest event of its kind in the world.

Why is it so hard to predict the outcome of competitions like the Premier League?

Football competitions are kicking off all around Europe in the coming days and weeks, including the world’s most watched division: The English Premier League. We might make our predictions on who we think is going to win a sporting competition but what factors are we considering? In this programme we look at some of the most popular variables that are taken into account when making sporting predictions and why even these have drawbacks. From upcoming football leagues to the Olympic Games, Head Analyst from Nielsen Gracenote, Simon Gleave tells us what are some of the most difficult sports to predict and why.

Are the media exaggerating how hot it is in the Mediterranean?

Reports on heatwaves across the globe have dominated our newsfeeds over the last few weeks, with temperatures said to have soared over the 40C mark in many parts of Europe. But across social media, not everyone is buying it. A trickle of scepticism swelled to a tidal surge, with people questioning whether temperatures are being hyped up by the wider media to drive fear and scare-monger. In this programme, we unpick allegations made about how these temperatures are recorded - and if they are accurate. We hear from Samantha Burgess at the Copernicus Climate Change Service; Alessandro Delitala from the Sardinia Environmental Protection Agency; and Sean Buchan from Climate Action Against Disinformation.

Data, extreme weather and climate change

Recent global headlines have been dominated by record temperatures across Europe, North America and parts of Asia. As extreme weather events have happened for decades, how are links to climate change made? In this programme we look at how scientists use data to draw climate conclusions and hear how that data isn’t always available, with a focus on severe flooding earlier this year in part of Central Africa. With Joyce Kimutai, principal meteorologist and climate scientist at the Kenya Meteorological Department and researcher at the Grantham Institute for Climate Change, Imperial College.

Ukraine war: A new way of calculating Russian deaths

Official information on the numbers of dead and injured in the Ukraine war has been in short supply. Little has come from either the Ukrainian or Russian sides, with estimates from western governments and intelligence agencies filling the information void. But some Russian journalists have been documenting war deaths and have come up with a new way of estimating fatalities using probate records. With contributions from David Frenkel, reporter at Mediazona and the BBC’s Russian Service correspondent Olga Ivshina. ... Read more

Immigration: A More or Less Special Programme

More than 1.2 million people came into the country to stay for more than 12 months in 2022. As only 560,000 left the country, this means net migration is at an all-time high. Both the Prime Minister and Home Secretary have said the number of people coming needs to come down. But who counts as an immigrant? How are the figures worked out? Charlotte McDonald will be finding out what the numbers tell us about who is coming to the UK and why. Plus - what about the people who left in 2022? ... Read more
