South Korea’s first monthly CO2 permit auction of the year sold out above secondary market prices, but it cleared well below last month’s record high.

Bees are essential to the functioning of America’s titanic almond industry – and billions are dying in the process

Dennis Arp was feeling optimistic last summer, which is unusual for a beekeeper these days.

Thanks to a record wet spring, his hundreds of hives, scattered across the central Arizona desert, produced a bounty of honey. Arp would have plenty to sell in stores, but more importantly, the bumper harvest would strengthen his bees for their biggest task of the coming year.

Even on a dull December day my local patch yields snatches of song and glimpses of egrets

A spare hour at dusk, on the last day of work before Christmas, and after a wet month I took the chance for a walk around my local patch. As often happens here, I saw virtually nothing for the first half of the walk: a few blackbirds chinking along the wooded drive, the rooks in the rookery by the car park.

And then, after dusk had fallen, when it was almost too dark to see, it all kicked off. First, two marsh harriers, floating low over the reedbed; then, no fewer than half a dozen great white egrets, each heading purposefully south to roost on the main Avalon Marshes. These elegant birds arrived here from France just a few years ago, enabled by the warming climate to extend their range northwards. Cetti’s warbler, another relatively recent arrival from continental Europe, wren and robin – the three birds that do sing during the winter – all uttered snatches of song.
