Fossil gives a peek into the lives of primitive birds that shared the Earth with the dinosaurs.

Nearly a fifth of European beetles that live in old and hollowed wood are at risk of extinction.

Our food – from what we eat to how it is grown – accounts for more carbon emissions than transport and yet staple crops will be hit hard by global warming

Did you know that what’s on your plate plays a larger role in contributing to climate change than the car you drive? When most wealthy people think about their carbon footprint, or their contributions to climate change, they’ll think about where their electricity and heat come from or what they drive. They’ll think about fossil fuels and miles per gallon, about LED lights and mass transit – but not so much about combine harvesters or processed meals or food waste. Few consider the impacts of the food they eat, despite the fact that globally, food systems account for roughly one quarter of all manmade greenhouse gas emissions. That’s more than the entire transportation sector, more than all industrial practices, and roughly the same as the production of electricity and heat.

Demise of the beetles, that need rotting wood to survive, could have devastating knock-on effect for other species, say scientists in a new report

Almost a fifth of Europe’s wood beetles are at risk of extinction due to a widespread decline in ancient trees, according to a new report which suggests their demise could have devastating knock-on effects for other species.

The study says 18% of saproxylic beetles – which depend on dead and decaying wood for some of their lifecycle – now exist on a conservation plane between “vulnerable” and “critically endangered”.

5 March 1968 The steelworks pool was largely frozen, and walking in line ahead across the ice were three big yellow-billed whooper swans

YORKSHIRE and NOTTINGHAMSHIRE
Over a desert of rubbish-strewn waste ground on the outskirts of Sheffield skylarks were singing, and a brace of partridges whirred up from a patch of tall dead weeds. The steelworks pool was largely frozen, and walking in line ahead across the ice were three big yellow-billed whooper swans, while six more were keeping open a small patch of water in the centre of the pool. For the most part these were motionless, only giving brief glimpses of their bill-patterns as they lifted their heads from their sleeping posture. The whooper breeds occasionally in Scotland, although there have been no published records of its doing so even there since 1939, but it is only a winter visitor to the rest of the British Isles.

Helvellyn, Lake District The combination of deep, drifting snow and mountain wind creates absorbing patterns

A flare of sun, a rush of endorphins, and the cloud scatters like a flock of birds to reveal the Patterdale fells, snowbound and sublime. There was not a speck of snow in overcast Glenridding but as we climbed the snow cover had gradually spread, until this sudden sunburst at about the 700 metre contour marked the feeling we had crossed from the valleys below to the winter hills above, a world charged with adventurous promise.

Our aim is Helvellyn’s Striding Edge, but I find myself being absorbed by the sculptures resulting from the combination of deep, drifting snow and mountain wind. The sinuous patterns in a banked-up gully are mesmerising, interlocking and racing downhill like river currents; ripples radiate across a snowdrift like the surface of a windblown lake; miniature cornices shaped like cresting waves create the illusion of a rolling sea frozen in time. Water is flowing everywhere, but without motion.
