Governments around the world have promised to fight climate change. But are they also pumping an absolutely massive amount of money into subsidies for fossil fuels? In 2022, an IMF working paper estimated that global subsidies for fossil fuels totalled $7 trillion. But when you dig into that research, you find that this number might not mean what you think it does. We explain how they reached that conclusion, with the help of Angela Picciariello from the International Institute for Sustainable Development, and Nate Vernon, one of the co-authors of the IMF paper.

Just hours after Donald Trump claimed victory in the US presidential election, rumours started swirling that something was afoot. A graph went viral on social media that appeared to show there were 20 million more votes cast in 2020 than in the 2024 election. Where had these supposedly âmissingâ votes gone? Conspiracy theorists on both sides of the political spectrum began shouting claims of fraud. The answer, it turns out, is rather more straightforward.

A huge quantity of clothing is produced every year around the world. But is so much made that there are already enough tops, trousers, skirts and all the rest to clothe humanity for decades into the future?
Thatâs a claim that has been percolating around the internet recently, that there are already enough clothes for the next six generations.
Tim Harford and Beth Ashmead Latham explore the source of this claim and, with help from Sabina Lawreniuk from Nottingham University, find that the evidence behind it is far from persuasive.

The great theories of economics seem to have great explanatory power, but the actual world is often far too complicated and messy to fully test them out.
Professor Ignacio Palacios-Huerta, an economist at the London School of Economics has an answer â sport. In the contained setting of competitive sport, he says, the rules are clear and you know who is doing what. This means, with some analysis, you can see vibrant illustrations of well-known economic theories playing out before your eyes.
Ignacio talks to Tim Harford about some of his favourite economic theories, demonstrated in action in sporting competition.
