There are only about 30 north Pacific right whales left after hunters nearly wiped out the slow-moving animals

Marine biologists for the first time have recorded singing by one of the rarest whales on the planet, the north Pacific right whale.

Researchers at the National Oceanic and Atmospheric Administration (NOAA) used moored acoustic recorders to capture repeated patterns of calls made by male north Pacific right whales.

Event will take place on 22 September across 18 boroughs, with road closures and events

Sadiq Khan has announced plans to implement London’s biggest car-free day to date, closing 12.3 miles (20km) of roads in the centre of the capital in September.

Roads will be closed for the event around London Bridge, Tower Bridge and much of the City of London to help tackle the capital’s air pollution crisis, which kills thousands of people each year and leaves two million – including 400,000 children – living in areas with illegally dirty air.

Seawalls could cost as much as the initial investment in the interstate highway system, with Florida facing $76bn, report finds

Defending against rising seas could cost US communities $416bn in the next 20 years, according to a new report.

Spending on seawalls alone could total almost as much as the initial investment in the interstate highway system, the authors said. And the billions involved will represent just a fraction of adaptation efforts governments in coastal states will have to fund if they do not want to simply retreat.

A daily summary of our news plus bite-sized updates from around the world.

Poll-leading Canadian Conservative Party leader Andrew Scheer said Wednesday that he would eliminate the ruling Liberals’ ‘backstop’ carbon tax and alter its output-based pricing system (OBPS) if elected as prime minister this fall, while potentially exploring the use of low-carbon exports to claim emission reductions towards the country’s Paris Agreement GHG target.

Female 12-year-old beluga whales Little Grey and Little White arrive at Klettsvik Bay

Two beluga whales from a Shanghai aquarium have arrived in Iceland to live out their days in a unique marine sanctuary that conservationists hope will become a model for rehoming 3,000 of the creatures currently in captivity.

Little Grey and Little White, two 12-year-old female belugas, left behind their previous lives entertaining visitors at the Changfeng Ocean World and were flown across the globe in specially tailored containers.

Human activities could be affecting reproduction and even normal social behaviour

Birds are even more disrupted by their noisy neighbours than had been thought previously, researchers have found. And human activities could be preventing birds from reproducing and even developing normal social behaviour and keeping the peace.

A study by Queen’s University Belfast found that when European robins were subjected to human produced noises their behaviour changed. Background noise appeared to mask the communication of crucial information between birds.
