Findings on decline of species such as Arctic tern and turtle dove published alongside flyways pledge at Kenya summit
One in nine migratory birds are threatened with extinction and 45% of migratory species such as cuckoos, turtle doves and Arctic terns are in decline, according to a global report.
The migratory slender-billed curlew was officially declared extinct last year, the first global bird extinction in mainland Eurasia and Africa in recent centuries. Worldwide, seven migratory bird species have been confirmed or are suspected to have become extinct over the last 150 years.

Customers seeking greens at one Berlin outlet are dealing with some very local supply chains indeed
Walking into the Felix Thomas REWE supermarket in Lankwitz, Berlin, customers are immediately presented with a choice of greens: romaine, rocket, iceberg. But last month, a new option joined the selection: Lankwitz loose-leaf lettuce. A combination of head lettuce, romaine lettuce, Lollo Rosso, and dark green easy leaf lettuce, its yellow packaging makes it stand out in a row of green. But it’s not just the flashy packaging that makes it distinct. Unlike its neighbouring lettuces, which come from regional farms or all the way from Italy, these greens were grown just a few metres away – or rather, a few metres up. “Frisch Vom REWE Dach” or “Fresh from the REWE roof”, the bags read.
Rooftop farms are nothing new: in cities such as Paris, Hong Kong, Copenhagen and New York, similar farms supply food to adjacent food retailers or even restaurants. This model has the potential to reduce greenhouse gas emissions from transportation (and its associated costs), minimise the urban heat effect, make use of dead space and perhaps even improve the relationship between buyers and their food.

Emissions of planet-heating methane and CO2 from natural sources are worsening the climate crisis, paper says
Rising global temperatures caused by the burning of fossil fuels are transforming the world’s forests, wetlands and tundra to the point they are releasing emissions that could further worsen global heating by as much as 30%, a new study has found.
As the world heats up, permafrost in the high latitudes is thawing, fiercer wildfires are burning in drying forests and wetlands and lakes are warming. All of these changes are themselves causing the release of planet-heating methane and carbon dioxide locked in trees and soils, therefore worsening the climate crisis, the paper states.

Record demand for A&E units, ambulance services and NHS 111 shows extreme heat having unprecedented impact on health, experts say
The NHS came under its most intense strain ever as a result of the summer’s five heatwaves, amid warnings that extreme heat is having an unprecedented impact on human health.
A&E units, ambulance services and the NHS 111 telephone advice line all experienced record demand for their services in England in June, July and August as Britain experienced record temperatures.

Environment Agency says talks under way about increasing prices for industrial users to try to reduce poor water management
Ministers are exploring making water more expensive for some users, in the face of severe supply shortages.
Despite the UK being a famously wet country, the precarious nature of the water supply has been made particularly acute this summer, with almost three-quarters of England and all of Wales in drought and 27 million people facing restrictions on their water use.

Hot weather means sweeter grapes, but outlook gloomier for beermakers, as drought diminishes barley harvest
English sparkling winemakers expect their earliest grape harvest and a “vintage year” after a scorching summer quickly ripened grapes.
However, beer sellers have warned of a potential shortage after record-breaking temperatures and a drought hitting much of England has caused poor yields of barley.

An artisanal mining boom driven by war and poverty is causing a public health emergency, as chemicals poison soil, water and society
In Abu Hamad, on the banks of the Nile, verdant orchards, gardens and fields once produced a bounty of dates, citrus fruits, winter grains and cereals for the towns and cities of eastern Sudan, including Khartoum and Port Sudan.
Today, the land looks drastically different. Trees have been cut down, agricultural areas cleared, and farms have been replaced by shops and commercial sites. Dotted around the town and its outskirts, more than 700 mounds of grey waste are poisoning the soil, water and air. The mounds are the toxic remnants of artisanal gold mining, a practice that began in about 2008 and has intensified over the past six years.

SMD is the moisture the soil must make up until it is at capacity, with very dry conditions over most of England and Wales
When the ground is thoroughly wet, after excess rainwater has run off it is said to be at field capacity. Meteorologists describe drought in terms of soil moisture deficit (SMD) from field capacity. The SMD is a measure of how thirsty the soil is, expressed as how many millimetres of rain it would take to top it up to field capacity.
In southern England, the SMD tends to hover around zero in winter when fields are wet. In summer it may be about 100mm, going up to 150mm or more in a dry year. The extreme of dryness, when soil has no water accessible to plants, is known as the permanent wilting point or PWP.

The island chain has tended to avoid the worst effects, but Hurricanes Lowell and Lala left a trail of damage this year
Hurricane Lowell surged near the Hawaiian Islands this week, leaving a trail of downed trees and power lines, crumbled roads, sunken boats and destroyed piers on the island of Kauai.
Residents were left to grapple not only with the damage, but the rising risks to the tropical archipelago as sea surface temperatures climb.
