World is home to 50bn birds, ‘breakthrough’ citizen science research estimates
University of New South Wales led study suggests six times as many individual birds as humans but that many species are very rare
There are about 50 billion individual birds in the world, according to new research that uses citizen science observations to try to estimate population numbers for almost 10,000 species.
The paper, led by scientists at the University of New South Wales, suggests there are about six times as many birds on the planet as humans – but that many individual species are very rare.

Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt
A significant part of the Greenland ice sheet is on the brink of a tipping point, after which accelerated melting would become inevitable even if global heating was halted, according to new research.
Rising temperatures caused by the climate crisis have already seen trillions of tonnes of Greenland’s ice pour into the ocean. Melting its ice sheet completely would eventually raise global sea level by 7 metres.

Jaguars could be reintroduced in the south-western US, where hunting and habitat loss led to the big cats’ extinction, a new study says.
Scientists and other environmentalists make the case for bringing back the third-largest big cat, after tigers and lions, in Arizona and New Mexico in a paper published in the journal Conservation Science and Practice.

How we talk about the climate crisis is increasingly crucial to tackling it | Susanna Rustin
Our emotional register – how ‘doomy’ or ‘hopeful’ we are – will inevitably shape the policies we put forward
As the climate emergency creeps closer to the top of the political agenda, where it belongs, an argument is raging over communication. Exactly what to say about the environmental crisis, and how, is an important question for all sorts of people and organisations, including governments. It is particularly pressing for journalists, authors and broadcasters. For us, communication is not an adjunct to other activities such as policymaking or campaigning. It is our main job.
People need to know what is happening to glaciers, forests and endangered species, and what is being done about this. But information requires interpretation. And while editorial judgments influence the way that all subjects are covered, storytelling about the climate emergency is particularly fraught.

Sharks use Earth’s magnetic field as ‘GPS’ guidance system, study says
- Florida scientists use juvenile bonnetheads for research
- Authors say findings applicable to other ocean-going sharks
Scientists in Florida have concluded that sharks possess an internal navigation system similar to GPS that allows them to use Earth’s magnetic forces to travel long distances with accuracy.

‘Catastrophic’: Sierra Leone sells rainforest for Chinese fish plant
Controversial deal with China would be ‘disastrous’ for fishing and protected rainforest, say opponents
A $55m (£39m) deal struck by the government of Sierra Leone with China to build an industrial fishing harbour on 100 hectares (250 acres) of beach and protected rainforest has been criticised as “a catastrophic human and ecological disaster” by conservationists, landowners and rights groups.
The gold and black sands of Black Johnson beach fringe the African nation’s Western Area Peninsula national park, home to endangered species including the duiker antelope and pangolins. The waters are rich in sardines, barracuda and grouper, caught by local fishermen who produce 70% of the fish for the domestic market.

Investigation reveals that ‘plastic waste coming from the UK to Turkey is an environmental threat, not an economic opportunity’
Turkey has become the latest destination for British plastic waste, which ends up dumped, burned or left to pollute the ocean, a Greenpeace investigation has found.
More than half of the plastic the British government says is being recycled are sent overseas, often to countries without the necessary infrastructure to do so. The UK exported 688,000 tonnes of discarded plastic packaging in 2020, a daily average of 1.8m kilos. Just 486,000 tonnes were recycled in the UK.

Project turns trophy hunters’ hit list into a conservation tool – and reveals the animals we most want to see caught on camera
For trophy hunters, the big five are the toughest, most dangerous animals to kill, but a photography project has turned the meaning of shooting on its head, creating a new list of the five most fantastic creatures to capture on camera.
More than 50,000 people from around the world voted for animals they most liked seeing pictures of as part of the New Big 5 wildlife photography list. The crowning creatures are elephant, lion, polar bear, gorilla and tiger, all of which are keystone species listed by the International Union for Conservation of Nature as either critically endangered, endangered or vulnerable.
