Snapshot

• Turkey held an “oceans and seas summit” as part of its COP31 preparations.

• El Niño has the potential to deepen a “hunger crisis”, said the UN.

• Carbon Brief explains the “gaps” in ocean protection.

• A new report found that 45% of migratory bird species are in decline.

• Human pressures contribute to infectious-disease outbreaks, said a new study.Key developmentsOceans rising

SEA SUMMIT: Turkey held an “oceans and seas summit” in Trabzon as part of the nation’s preparations for hosting the COP31 climate summit in November, reported the Daily Sabah. COP31 president-designate Murat Kurum stressed that oceans would be a priority in the summit’s “action agenda”. The Turkish presidency said it would work with Australia’s COP31 team – which will lead the formal negotiations – to elevate oceans, “including through engagement with the Pacific” at the “pre-COP” in Fiji, according to Climate Home News.

LOSS AND DAMAGE: Carbon Brief has published an explainer detailing how sea level rise threatens everything from coral reefs to coastal heritage sites. Meanwhile, as a UN “loss and damage” committee met in the Marshall Islands capital of Majuro, government official Jerolynn Myazoe stated the nation was “already seeing” the impacts of rising seas, according to the Pacific News Service.

FISH AND SPONGES: The Guardian reported on nine new species of Alaskan deep-sea sponge, noting that “their habitat is threatened by bottom trawling” and US plans to “expand seafloor mining”. A new report by the Blue Marine Foundation concluded that “political decisions” in the UK have brought fish populations “to the point of collapse”. Meanwhile, the Scottish government has “opened a consultation” on fisheries management within the nation’s marine protected areas, said Oceanographic.Super El Niño

HUNGER CRISIS: An expert from the UN World Food Programme (WFP) has warned that El Niño is deepening a “hunger crisis” in South Sudan, according to UN News. Separately, the Guardian reported that, according to WFP, “about 50 million people will probably be pushed into acute hunger” due to the phenomenon. RFI reported that “drought has destroyed maize and bean crops” in central America, while “in Peru, unusually warm waters have driven anchovies away from the coast”. Carbon Briefanalysis showed that the ongoing El Niño has already entered “record-breaking territory”.

END OF ABUNDUNCE: The Observer reported that the “sense of food abundance” enjoyed by UK consumers could be threatened by El Niño. According to the outlet, “suppliers in the UK rely on switching [their imports] between countries as seasons shift in order to keep shelves stocked all year round, but El Niño is disrupting that planning”. Separately, Food Navigator outlined “which food commodities are threatened most” by the climate pattern.News and views

BAD NEWS BIRDS: The latest “State of the World’s Birds” report found that “45% of migratory bird species are in decline, with 11% threatened with extinction”, according to Mongabay. The outlet warned that “invasive species, agricultural expansion, climate change, residential and commercial development and hunting” threaten bird species.
LAND DEFENDERS: The Global Witness land defenders report found that “at least 124 land and environmental defenders were killed in 2025”. The Guardiannoted that Latin America “accounted for 85% of last year’s deaths of people trying to protect forests, rivers and other ecosystems”.
FOOD RESILIENCE: “Agri-food companies, farmers and governments are already paying for the physical impacts of climate and nature on agricultural supply chains,” according to a report from the Food and Land Use Coalition. The report warned that investment is needed to build the resilience of agricultural systems.
REGENERATIVE RISE: India’s “agricultural carbon market” has distributed around $300,000 between 2,550 small farmers “through digital payments for adopting regenerative farming practices”, according to Telangana Today. Meanwhile, Civil Eats reported on a consumer survey showing rising awareness of regenerative farming in the US.
AMAZON ELECTION: Ahead of the Brazilian presidential election, Sentientstated that “deforestation is on the ballot”. Incumbent president Luiz Inácio Lula da Silva will likely face off directly against rightwing senator – and former president Jair’s son – Flávio Bolsonaro.
BIG CHANGES: “Planetary life support systems” have deteriorated to their “worst levels ever recorded”, based on seven indicators, including climate change, land-system change and freshwater change, according to the Guardian.

SpotlightThree critical ‘gaps’ in ocean protection

This week, Carbon Brief covers the new “Ocean Protection Gap” report, which examines the state of global marine protection.

Ocean protection is “rising”, but will still fall short of the world’s 2030 target without “rapid progress”, according to the new “Ocean Protection Gap” report.

The report is one of two published today that assessed the world’s progress towards its “30 by 30” target – a pledge to protect 30% of the world’s land and seas by 2030.

Every country in the world, except for the US and the Holy See, signed on to the 30 by 30 pledge as part of the Kunming-Montreal Global Biodiversity Framework in 2022.

The two reports were covered in the global news media, including by Reuters, Deutsche Welle and a column in Time by Danny Faure, former president of the Seychelles.

Here, Carbon Brief unpacked the three key “gaps” – ambition, implementation and finance – identified in the report.

Ambition

The report found that just under half of coastal countries have set quantified, time-bound targets towards achieving 30 by 30 in their territorial waters – with 22 countries setting their targets within the last year.

One-quarter of the remaining 84 countries have set targets that are either not quantified, not time-bound, or both.

However, even if countries were to meet their formal ocean-protection targets by 2030, this would still only account for around 26% of national waters – and just 12% of the global ocean.

This is significantly smaller than the area of land and inland waters that is already protected, noted the report.

Since the “high seas”, or waters outside of national jurisdiction, make up nearly two-thirds of the global ocean, “achieving 30 by 30 is all but impossible…without rapid progress” there, it added.

Implementation

However, even if these area-based targets were to be achieved, said the report, this alone is “no longer a sufficient measure of progress”.

Many areas that are reported as protected still allow for damaging practices, such as industrial fishing, seabed mining or fossil-fuel exploration. This leaves the area of ocean that is effectively protected “concerningly low”, said the report.

This shows that “designation alone does not guarantee biodiversity outcomes”, it added.

The converse of this is that some areas that are not formally recognised as protected – known as “other effective area-based conservation measures”, or OECMs – can contribute to achieving biodiversity goals, but are generally not included in global protected-area statistics.

OECMs can include Indigenous territories, natural-heritage sites and protected watersheds. They differ from protected areas in that conservation is not necessarily the primary goal of the area.

Properly accounting for the contributions of Indigenous peoples’ lands and waters to the 30 by 30 target will be one of the key topics discussed at the UN biodiversity summit in Yerevan, Armenia, next month.

Finance

Access to finance is still the “biggest constraint on delivering effective protection” for the oceans, according to the report.

This is despite the economic benefits that ocean protection can bring, it added: protecting coastal wetlands and seagrass meadows, along with helping fish stocks recover, could generate an estimated $85bn annually by 2050.

While finance for global ocean protection has increased by around 50% over the last year, to $1.8bn, it is still less than one-tenth of the estimated need. The amount spent on ocean protection also pales in comparison to the amount spent each year on subsidising harmful fishing practices, added the report:

“The finance required is modest relative to the value at stake and to the public money still supporting ocean degradation.”
