Further to Peter Avery’s letter about watching cricket outside a TV rental showroom (4 August), in the late 1960s I was an avid follower of the Apollo space missions. One day the BBC announced the next broadcast from the capsule was going to be the first in colour. We did not have a colour set, so I made sure I was in the shopping centre so I could watch it in a shop window.

• China may be the biggest source of carbon emissions on earth (Unsurvivable heatwaves could strike heart of China by end of century, 1 August) but it is not the biggest emitter per capita. According to the World Bank, that dishonour among industrialised economies goes jointly to Australia, Canada and the US. China is leading the world – with Germany – in developing renewable sources of energy.

• My mother was in Petra in the late 1980s (Letters, 6 August) tottering up the monastery hill on a donkey when she spotted Denis Healey. She introduced herself as a lifelong Labour member and when they reached the top they both shouted very loudly “Maggie, Maggie, Maggie, out, out, out”.

• Zoe Williams (Opinion, 2 August) wonders why the older generation rush to answer every phone call. Maybe it’s because telephones were few and far between and only to be used for really important matters. Too often we are disappointed by PPI merchants or ambulance chasers, but we remain an optimistic lot.

• Ask Fiona Bruce (Painting sold for $450m ‘not really by Leonardo’, 6 August): she always knows.
