Arctic seals are being pushed closer to extinction by climate change and more than half of bird species around the world are declining under pressure from deforestation and agricultural expansion, according to an annual assessment from the International Union for Conservation of Nature.
One bright spot is green sea turtles, which have recovered substantially thanks to decades of conservation efforts, the IUCN said Friday as it released its latest Red List of Threatened Species.
While many animals are increasingly at risk of disappearing forever, the updated list shows how species can come back from the brink with dedicated effort, Rima Jabado, deputy chair of the IUCN Species Survival Commission, told The Associated Press.
“Hope and concern go hand in hand in this work,” Jabado wrote by email. “The same persistence that brought back the green sea turtle can be mirrored in small, everyday actions — supporting sustainable choices, backing conservation initiatives, and urging leaders to follow through on their environmental promises.”
The list is updated every year by teams of scientists assessing data on creatures around the world. The scope of the work is enormous and important for science, said Andrew Farnsworth, a visiting scientist at the Cornell Lab of Ornithology who studies bird migration and wasn’t involved with the IUCN report.
“Every time one is done and every time there’s revision, there’s more information, and there’s more ability to answer questions” on species, some of which are still largely a mystery to researchers, Farnsworth said.
Sea ice loss
Because all the marine mammals native to the Arctic — seals, whales and polar bears — rely on the habitat provided by sea ice, they’re all at risk as it diminishes because of human-caused climate change, said Kit Kovacs, co-chair of IUCN’s Species Survival Commission Pinniped Specialist Group, which focuses on seals.
The three species highlighted in the latest IUCN report _ harp, hooded and bearded seals — have been moved up to a designation of greater concern in the latest update, indicating they are increasingly threatened by extinction, Kovacs said.
The same melting of glaciers and sea ice destroying seal habitats also “generally will bring escalation in extreme weather events, which are already impacting people around the globe,” wrote Kovacs.
“Acting to help seals is acting to help humanity when it comes to climate change,” Kovacs said.
Global bird decline
The update also highlighted Madagascar, West Africa and Central America, where Schlegel’s asity, the black-casqued hornbill and the tail-bobbing northern nightingale-wren were all moved to near-threatened status. Those are three specific birds in trouble, but numbers are dropping for around three-fifths of birds globally.
Deforestation of tropical forests is one of a “depressing litany of threats” to birds, a list that includes agricultural expansion and intensification, competition from invasive species and climate change, said Stuart Butchart, chief scientist at BirdLife International.
“The fact that 61% of the world’s birds are declining is an alarm bell that we can’t afford to ignore,” Butchart said.
The annual U.N. climate summit will be held in November in Belem, Brazil, with much attention on the Amazon and the value of tropical forests to humans and animals. But Farnsworth, of Cornell, said he was “not so confident” that world’s leaders would take decisive action to protect imperiled bird species.
“I would like to think things like birds are nonpartisan, and you can find common ground,” he said. “But it’s not easy.”
Green sea turtles
One success story is the rebound of green sea turtles in many parts of the world’s oceans. Experts see that as a bright spot because it shows how effective human interventions, like legal protections and conservation programs, can be.
Still, “it’s important to note that conservation efforts of sea turtles can take decades before you realize the fruits of that labor,” said Justin Perrault, vice president of research at Loggerhead Marinelife Center in Juno Beach, Florida, who wasn’t involved with the IUCN report.
The overall success with green sea turtles should be celebrated and used as an example with other species, some of which, like hawksbills and leatherbacks, aren’t doing nearly as well, said Nicolas Pilcher, executive director of the Marine Research Foundation.
And even for green sea turtles, areas still remain where climate change and other factors like erosion are damaging habitats, Pilcher said, and some of those are poorer communities that receive less conservation funding.
But in the places where they have recovered, it’s “a great story of, actually, we can do something about this,” Pilcher said. “We can. We can make a difference.”

World's coral reefs crossing survival limit: Global experts
It is the first time scientists have declared that Earth has likely reached a so-called 'tipping point'

Coral reefs are highly sensitive to changing conditions in the oceans and global warming poses the greatest threat to these vibrant ecosystems.
Coral reefs are highly sensitive to changing conditions in the oceans and global warming poses the greatest threat to these vibrant ecosystems.
The world’s tropical coral reefs have almost certainly crossed a point of no return as oceans warm beyond a level most can survive, a major scientific report announced on Monday.
It is the first time scientists have declared that Earth has likely reached a so-called “tipping point” — a shift that could trigger massive and often permanent changes in the natural world.
“Sadly, we’re now almost certain that we crossed one of those tipping points for warm water or tropical coral reefs,” report lead Tim Lenton, a climate and Earth system scientist at the University of Exeter, told AFP.
This conclusion was supported by real-world observations of “unprecedented” coral death across tropical reefs since the first comprehensive assessment of tipping points science was published in 2023, the authors said.
In the intervening years, ocean temperatures have soared to historic highs, and the biggest and most intense coral bleaching episode ever witnessed has spread to more than 80 percent of the world’s reefs.
Understanding of tipping points has improved since the last report, its authors said, allowing for greater confidence in estimating when one might spark a domino effect of catastrophic and often irreversible disasters.
Scientists now believe that even at lower levels of global warming than previously thought, the Amazon rainforest could tip into an unrecognizable state, and ice sheets from Greenland to West Antarctica could collapse.
– ‘Unprecedented dieback’ –
For coral reefs, profound and lasting changes are already in motion.
“Already at 1.4C of global warming, warm water coral reefs are crossing their thermal tipping point and experiencing unprecedented dieback,” said the report by 160 scientists from dozens of global research institutions.
The global scientific consensus is that most coral reefs would perish at warming of 1.5C above preindustrial levels — a threshold just years away.
When stressed in hotter ocean waters, corals expel the microscopic algae that provides their distinct colour and food source.
Unless ocean temperatures return to more tolerable levels, bleached corals simply cannot recover and eventually die of starvation.
Since 2023, marine scientists have reported coral mortality on a scale never seen before, with reefs turning ghostly white across the Pacific, Indian and Atlantic oceans.
“I am afraid their response confirms that we can no longer talk about tipping points as a future risk,” Lenton told reporters.
Rather than disappear completely, scientists say reefs will evolve into less diverse ecosystems as they are overtaken by algae, sponges and other simpler organisms better able to withstand hotter oceans.
These species would come to dominate this new underwater world and over time, the dead coral skeletons beneath would erode into rubble.
Such a shift would be disastrous for the hundreds of millions of people whose livelihoods are tied to coral reefs, and the estimated one million species that depend on them.
– ‘Danger zone’ –
Some heat-resistant strains of coral may endure longer than others, the authors said, but ultimately the only response is to stop adding more planet-warming greenhouse gases into the atmosphere.
Exceeding 1.5C “puts the world in a greater danger zone of escalating risk of further damaging tipping points”, Lenton said, including the collapse of vital ocean currents that could have “catastrophic” knock-on impacts.
Scientists also warned that tipping points in the Amazon were closer than previously thought, and “widespread dieback” and large-scale forest degradation was a risk even below 2C of global warming.
That finding will be keenly felt by Brazil, which on Monday is hosting climate ministers in Brasilia ahead of next month’s UN COP30 conference in Belem on the edge of the Amazon.
In good news — the exponential uptake of solar power and electric vehicles were two examples of “positive” tipping points where momentum can accelerate for the better, said Lenton.
“It gives us agency back, policymakers included, to make some tangible difference, where sometimes the output from our actions is sometimes disproportionately good,” he told AFP.

CO2 in atmosphere up by record amount in 2024: UN

The jump in carbon dioxide in the atmosphere last year is the highest ever recorded, according to the UN.
GENEVA — The increase in the amount of carbon dioxide in the atmosphere last year was the highest ever recorded, the United Nations said Wednesday, calling for urgent action to slash emissions.
Levels of the three main greenhouse gases — the climate-warming CO2, methane and nitrous oxide — all increased yet again in 2024, with each setting new record highs, the UN’s weather and climate agency said.
The World Meteorological Organization said the increase in CO2 levels in the atmosphere from 2023 to 2024 marked the biggest one-year jump since records began in 1957.
Wednesday’s report, which comes ahead of the November 10-21 COP30 UN climate summit in Belem, Brazil, focused exclusively on concentrations of greenhouse gases in the atmosphere.
A separate UN report, out next month, will detail shifts in emissions of the gases, but those numbers are also expected to rise, as they have every year with the world continuing to burn more oil, gas and coal.
This defies commitments made under the 2015 Paris Agreement to cap global warming at “well below” 2C above average levels measured between 1850 and 1900 — and 1.5C if possible.
The WMO voiced “significant concern” that land and oceans were becoming unable to soak up CO2, leaving the powerful greenhouse gas in the atmosphere.
“The heat trapped by CO2 and other greenhouse gases is turbo-charging our climate and leading to more extreme weather,” said WMO Deputy Secretary-General Ko Barrett.
“Reducing emissions is therefore essential not just for our climate but also for our economic security and community well-being.”
Last year was also the warmest year ever recorded, beating the previous high in 2023, the WMO recalled.
“The levels of the three most abundant long-lived greenhouse gases — carbon dioxide, methane and nitrous oxide — reached new records in 2024,” the WMO said in its 21st annual Greenhouse Gas Bulletin.
In 2024, CO2 concentrations were at 424 parts per million (ppm), methane at 1,942 parts per billion, and nitrous oxide at 338 parts per billion.
That marks hikes of 152 percent, 266 percent and 125 percent respectively since pre-industrial levels before 1750.
Of the three major greenhouse gases, CO2 accounts for about 66 percent of the warming effect on the climate.
When the Greenhouse Gas Bulletin was first published in 2004, the figure stood at 377 ppm.
The 3.5 ppm increase from 2023 to 2024 was “the largest one-year increase since modern measurements began in 1957”, the WMO said.
