Tokyo It is now 26 years since the doomsday cult known as Aum Shinrikyu (‘supreme truth’) carried out the worst domestic terrorist attack in Japanese history. Led by their leader Shoko Asahara, Aum released sarin gas on to the Tokyo subway, killing 13 and injuring 6,000. It remains the only time a weapon of mass destruction has been deployed by a private organisation. The details were sickening: one woman had to have her eyes surgically removed because the nerve gas fused her contact lenses on to them.

Earlier this year, a report from climatologists around the world made it clear that climate change is happening now and that it is almost entirely a result of human behaviour. This is not a controversial conclusion and it is not hard to explain how the report’s authors arrived at it. First, independent observations — from the ocean to the atmosphere, from poles to tropics — all show rapid and significant warming over the past century, particularly over the past few decades.

Facebook has rebranded itself as Meta and last month chief executive Mark Zuckerberg announced the creation of 10,000 jobs to help build the ‘metaverse’ — a concept so radical nobody yet knows what it really is. People in the media tend to describe it as ‘a 3D version of the internet’. Facebook describes it rather vaguely as a network of ‘virtual spaces where you can create and explore with other people who aren’t in the same physical space as you’.

Hungarian politics has a lot to offer: sex tapes, offshore bank accounts, police-dodging MEPs hanging off drainpipes, supposedly left-wing parties cheerfully backing anti-Semitic parliamentary candidates. Nevertheless, most observers would admit that there has been stagnation in the past few years. Hungary’s politics have become a stale exchange of insults between familiar faces. Thank goodness, then, for Péter Márki-Zay, who has opened a window and let in some fresh air.

Many people love to hate bagpipes. Everyone from William Shakespeare to Alfred Hitchcock has held them in contempt. For some, they are almost a form of punishment. Last week, a frustrated motorist blasted bagpipe music in the faces of Insulate Britain protestors on the M25 before he was stopped by police. Most pipers will tell you they are sick of hearing that the definition of a gentleman is someone who knows how to play the bagpipes and doesn’t.
