Modern irritations seem to come in threes. No sooner do you trip over a Lime bike ‘parked’ on its side in the middle of the pavement than you discover that the self-checkout in the Co-op has a handwritten note stating ‘out of order’ taped to it and the man in front of you in the queue for the sole remaining human-staffed counter is attempting to buy (and scratch) 14 lottery tickets.  That’s what happened on my venture out of the house this morning, anyway. The experience sent me scurrying home again to muse on whether I have had a more dispiriting, in the picayune sense, start to any morning this

The song of the bearded seal and other marvels

In his satirical Devil’s Dictionary, Ambrose Bierce defined the ocean as ‘a body of water occupying about two thirds of a world made for man – who has no gills’. Bierce may have been right to poke fun at human arrogance, but he underestimated the importance of the seas. Averaging almost 3,700 metres (12,000ft) deep, the ocean constitutes around nine tenths of the habitable space on our planet. It plays a commensurate role in the Earth system, not least as an engine – a ‘blue machine’ in the phrase that also titles an excellent book by the physicist and science presenter Helen Czerski – that moves heat around the planet.
