At the grand old age of 20, Wikipedia remains one of the world’s most popular websites. The fact that anyone with internet access can edit its pages is a key part of its success. But the website’s openness to the public is also the reason why it has become an unlikely battleground on global warming.
 
Despite the overwhelming body of science proving climate change is real and man-made, deniers are still active on Wikipedia. Whether it is by editing climate pages or spreading conspiracy theories, they have for a long time tried to reframe our understanding of climate change.
 
But a small group of dedicated volunteers is determined to keep them at bay, setting the record straight on the facts and the science behind global warming.
 
In this episode of the Denial Files, we set out to meet some of those volunteers and investigate how vulnerable Wikipedia remains to climate denial today.

In 2024 yet another Kennedy is making a bid for the White House. Robert F Kennedy Jr - nephew of the late President John F Kennedy - is enjoying strong polling numbers for an independent candidate. He’s running on a platform of promising to take on powerful vested interests to create a better life for the average American.  But away from his Camelot-infused stump speeches, he is facing questions about his long and controversial record of spreading misinformation about the safety of vaccines. In this episode, the BBC’s Health and Disinformation Reporter Rachel Schraer investigates how Kennedy is building a base from across the political spectrum, inspite of, or because of, his views on public health policy.

Catalysed by social media, the protests would reverberate around the world, spark the Arab Spring and lead to significant democratic reforms in the country.  More recently, Tunisia’s democracy has reached a turning point. In 2021, as public frustration with the pandemic and the failing economy grew, the Tunisian President Kais Saied sacked the prime minister, suspended parliament and pushed through constitutional reforms consolidating his power. And now, it appears online debate is being suppressed. BBC Trending speaks to people who have experienced first hand how social media can be used to survey and attack the government’s critics.

Fear and conspiracies in Las Vegas

"A flood of disinformation has erupted across social media in the online propaganda battle that’s being waged alongside the physical conflict between Israel and Hamas.
