Over 40% of global shipping by volume exists to move fossil fuels from one place to another.

A huge share of the world's maritime infrastructure has been built around a system that is going to change dramatically as renewable energy and electrification displace fossil fuels.

This World Wildlife Day is a reminder that foraging is part of our heritage Jon Conradi, Wild Mosaic This year, World Wildlife Day is about plants. This took me by surprise. Typically when I think of wildlife, I think of animals, perhaps with some vegetation as background. I ...

A few generations ago, most communities would have had knowledge of their local wild plants and their uses. This loss of knowledge is a loss of our heritage, as well as evidence of our disconnection ✍️Jon Conradi, Wild Mosaic

Why don’t we ever see snakes slithering in the snow? 🐍

These cold-blooded creatures can’t hibernate - but they do have their own special skill to survive the snow and cold. ❄️

Jurassic amphibian with a projectile tongue named as a new species | Natural History Museum A new species of amphibian that lived 150 million years ago has been discovered in Portugal.

Scientists have recently discovered a Jurassic amphibian that had a projectile tongue!

The new species has been named Nabia civiscientrix after the local community of citizen scientists that helped to discover the fossil.

Close up of a handwritten label on a fossil specimen: 'This Fossil is the first I ever obtained. It was purchased from Mary Anning in July 1824. It then wanted the point of the nose. This was found 3 years after rolled on the sands & she sent it to me to Oxford – Enniskillen'

Vulcanodon is one of the earliest sauropods but it’s named for the shape of several theropod teeth referred in error to the type, as they were found in association with the skeleton (at a time when many β€˜prosauropods’ were considered carnivores). Enjoy πŸ¦–πŸ¦•πŸ‡ΏπŸ‡Ό

Really sad news. Hans worked on an incredible diversity of vertebrate groups but in particular made huge contributions to our understanding of the Triassic.

*Global warming* refers to the increase in average global temperature due to greater atmospheric CO2 which slows down the rate at which the Sun's energy is lost.

*Climate change* refers to changes in regional weather systems typically measured over a thirty year period.

Two images of Earth illustrating the difference between Global Warming and Climate Change. 

Global Warming: an orange Earth with a schematic of infrared from the surface being redirected downwards by the atmosphere. It's labelled "The gradual increase of the surface temperature of Earth"

Climate Change: a blue green Earth showing a desert, a schematic volcano, and a schematic hurricane. It's labelled "The long-term change in global weather patterns".

*#GlobalWarming* and *#ClimateChange* are both valid terms that mean different things.

A large, suspended dragon sculpture crafted from translucent materials in shades of blue, green, and yellow dominates the upper part of a museum space, giving the impression of flight. Below it, various display cases and exhibition stands can be seen, along with a crocodile model placed atop a mosaic-patterned platform in the foreground. The vibrant dragon contrasts with the warm tones and historic architecture of the museum interior. Overlaid text promotes the "Mythical Creatures" exhibition at Colchester Castle, running from 26 July 2025 to 22 February 2026. The castle logo and Tom Archer’s photo credit are also present.
