Replacing diesel-powered ferries with electric vessels could reduce emissions and improve air quality

Cutting through New York Harbor in the shadow of the Statue of Liberty, the small white boat we were riding on caught the attention of passengers aboard a nearby sightseeing ferry.

“It’s quite a curiosity at the moment,” Eric Laakmann, the chief executive and co-founder of Vessev, said.

Almost every shallow-water coral reef on the planet, including Australia’s Great Barrier Reef, faces a high risk of ecosystem collapse before 2075 because of global heating, according to an assessment by United Nations nature advisers.

About 24% of the planet’s reefs across more than 80 countries are already critically endangered, the assessment said, but when the expected impacts of global heating were added this rose to 96%.

When Wendy Wales and Tony Lonergan and a few of their neighbours in the New South Wales Hunter region decided to take on the expansion of a local coalmine, people thought they were “crazy” to engage in the David and Goliath battle.

“When we started this, people thought we were crazy – a little community group taking on a billion-dollar coal company, arguing that the climate harm from burning this coal is our problem too,” Wales says.

Exclusive: Images show deep cuts and damage to tails and fins, as experts warn the migrating species often aren’t able to avoid a collision

Gruesome images of adult and juvenile humpback whales along Australia’s east coast with slash and gouge injuries from boat and propeller strikes highlight what experts say is a growing problem, as the population booms 60 years after the ban on whaling.

Missing tail parts, deep red lacerations and shocking injuries to the spine of a whale calf can be clearly seen on the images, gathered by WWF Australia and shared with the Guardian.

Antarctica’s winter sea ice has peaked at its third-lowest level on record, falling a million square kilometres – or almost 400,000 square miles – short of the long-term average, scientists have confirmed.

Confirmation of the peak meant the four lowest years on record for the continent’s sea ice – a vital component of the planet’s climate and critical for marine life – had all occurred in the past four years.

Global heating contributes to record, with a warmer atmosphere able to hold more water, scientists say

The planet’s atmosphere held more water vapour in August than any other month on record, further increasing the risk of extreme heat and rainfall around the world, according to Europe’s climate change service.

Climate scientists said global heating was a contributor to the record because a warmer atmosphere can hold more water, and the historic El Niño in the Pacific Ocean was also likely pushing water vapour levels up.

Organisation says objects consistent with ‘debris from a foreign rocket body that recently re-entered the atmosphere’

The Australian Space Agency has said the six so-called “space balls” found in north Queensland were likely from a “foreign rocket body” that had recently re-entered the atmosphere after being in orbit.

The six mysterious objects were found by the public washed ashore in the Forrest Beach area, north of Townsville, on Friday, Saturday and Sunday and were suspected of containing hazardous chemicals.

Scientists fear unique corals that fringe Australia’s remote Norfolk Island could disappear because of a triple threat of disease, El Niño and a federal government plan to dredge a neighbouring shipping channel.

A failure to manage sediment and pollution washing into bays from cattle farming, cleared land along with wastewater has been blamed for widespread disease and outbreaks of algae over the corals.

Exclusive A vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’

Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.

One expert said the loss of ice in the Bellingshausen Sea was “depressing” and the failure of ice to form could have intensified a heatwave over the continent’s peninsular last week that saw daytime temperatures peak at 15.4C which is more than 20C above average.

A humpback whale has made a 15,000km journey from Brazil to Australia, marking what researchers believe is the longest distance ever documented between sightings of an individual humpback.

The whale was first photographed in 2003 at the Abrolhos Bank, Brazil’s main humpback whale nursery, off the coast of the north-eastern state of Bahia. In September 2025, it was spotted again in Hervey Bay off the Queensland coast, representing a travel distance of about 15,100km.

Divers are installing waterproof speakers in the ocean to help pull a coral reef near Jamaica back from the brink

The northern coast of Jamaica once served as the backdrop for scenes in the James Bond thriller No Time to Die. But today, beneath those same turquoise waves, a real-life mission is unfolding: the race to pull a dying coral reef back from the brink.

However, the tools a team of divers are carrying to the seafloor are not what you would expect to find in a marine biologist’s kit. They are installing waterproof speakers at the bottom of the ocean, and the man leading the team is not a scientist.
