🫁 You take my breath away! As the sea temperature rises, the ocean risks deoxygenation, one of the most alarming #ClimateChange impacts. What are the causes and future impacts? Find out more in our Issue Briefing ➡️ https://www.oceanprotect.org/resources/issue-briefs/hypoxia/

Unexpected heatwave winners: endangered sunflower stars from Washington’s Salish Sea handle heat surprisingly well. 🌻 Early life stages tolerate, and often perform best at, temperatures expected under current and near-future warming. #MarineHeatwaves

DYK? At Pacific hydrothermal vents, a deep-sea worm can turn two poisons into one harmless solid, a toxic pigment, which has been used by painters for centuries. 🎨 Read more: https://www.nature.com/articles/d41586-025-02771-9

Nanoplastics are widespread across the Arctic Ocean, from coastal waters to the central basin. Sea ice and atmospheric transport play key roles in storing and redistributing these tiny plastic particles, raising concerns for Arctic ecosystems. https://www.nature.com/articles/s44454-025-00024-y

Wetlands play a key role in the coastal carbon cycle, yet remain vulnerable to extreme weather. Study by @scrippsocean.bsky.social found that ocean warming will erase much of the recovery & shrink global mangrove area. #WorldWetlandsDay https://iopscience.iop.org/article/10.1088/2752-5295/adffa9

🌊 Conservation must keep pace with a moving ocean. The authors of this Comment call for inclusive governance, stronger monitoring and evaluation, and the use of accessible digital tools, among other key recommendations. These steps would make #MPAs more effective and help meet the #30x30 target.

As sea levels rise and climate hazards intensify, communities are relocating. More than half of the world’s coastal regions saw people move inland since 1992. In contrast, low-income areas still edge closer to the coast, despite rising risks. Adaptation capacity determines who can retreat.

📢 Calling for feedback from ocean stakeholders, experts and citizens! @ec.europa.eu has launched a public call for evidence to help shape the #EUOceanAct, a proposed law set for adoption in 2026. Deadline: 9 February 2026

Pessimistic outlooks can limit action and reinforce helplessness. This study shows how moving beyond bleak narratives can unlock new ways of thinking about #CoralReef conservation. Visioning exercises may help inspire action and guide more just and sustainable reef futures.

75 of the largest firms across eight ocean-economy sectors focus on energy but not on ocean-specific impacts and targets in their annual reports. Authors recommend setting simple, ocean-specific rules and targets. @sthlmresilience.bsky.social @oceansolutions.stanford.edu

DYK? Oyster farms can help pull CO2 from the air, not just grow seafood. Authors suggest that shellfish aquaculture should be considered within marine carbon removal (mCDR) and blue carbon frameworks for #ClimateChange mitigation. https://www.pnas.org/doi/10.1073/pnas.2504004122

#ClimateChange harms the ocean in ways that have a huge economic toll. New study from @scrippsocean.bsky.social#ClimateChangeis the first to integrate the ocean’s climate impacts. It estimates nearly $2 trillion in annual ocean-related damages currently missed by models.

UN talks to end #PlasticPollution stalled in August 2025. Countries split over capping virgin plastics, what counts as “plastic,” and who pays. The authors say progress requires bridging ambitions with economic realities.

We may be entering a maritime century, where ocean governance and climate action are inseparable. At #COP30, the ocean shifted from the margins to the mainstream of climate diplomacy, with the 🌊 ocean recognised as an essential part of climate solutions. europesays.com/2686707/

Across 8 countries, large majorities back the #30x30 goal. Support grows when all nations share protection duties, richer nations pay more, more countries join in and “buying protection abroad” is barred. At home, people prefer nature-first siting and polluter-pays funding. https://bit.ly/4jALfRy

It's #PenguinAwarenessDay! 🐧 Some believe penguins live in the North Pole, however, they live in #Antarctica and the sub-Antarctic islands, where 8 of the 17 species can be found. What fun fact do you know about penguins? Learn more facts: https://bit.ly/4jG0SHC

As part of the celebrations for #WorldGlaciersDay, @unesco.org#WorldGlaciersDayis calling for side-events at its HQ in Paris on 19–20 March 2026. If you are interested, send your expression of interest by Jan 30 👉 https://www.unesco.org/en/articles/call-expressions-interest-world-day-glaciers-2026

❗The world’s ocean absorbed more heat in 2025 than any year, continuing an alarming trend of rising ocean heat content. Research from 30 global institutions warns of intensifying climate impacts, such as #SeaLevelRise, extreme weather and marine ecosystem stress, as a result. @sciam.bsky.social#SeaLevelRise

Microplastics may weaken ocean’s ability to absorb CO2, reducing one of Earth’s most important natural defences against #ClimateChange. Authors call for global action to reduce plastic production, improve waste management & deepen research on plastic pollution interaction with climate processes.

🌊 A historic day for the ocean! The #HighSeasTreaty has officially entered into force, a win for multilateralism and for our blue planet. Next step: universal ratification! 👏 Well done to our member @highseasalliance.bsky.social#HighSeasTreaty #60toGlobal

The @unoceandecade.bsky.social is driving global cooperation to expand ocean observing systems, improve data access and integrate diverse knowledge. By linking science, policy and capacity development, it aims to make ocean monitoring a core service for sustainability and climate resilience.

A short, hands-on #OceanLiteracy programme around Guanabara Bay🇧🇷 helped previously disengaged students see the bay’s degradation as a historical, social problem. Activities strengthened their support for protection and showed how local case studies can spark critical thinking and ocean citizenship.

How can we scale up climate knowledge for real-world use? ☑️ broaden participation ☑️ diffuse tools to new users ☑️ work with influential decision-makers. Success depends on balancing impact with equity and benefits or unintended harm. @uofmpress.bsky.social #ClimateAction

After 25 years of negotiations, the @wto.org fisheries subsidies agreement is a major breakthrough, but it is only a first step. Authors suggest a follow-up agreement, wider coverage & better enforcement by 2029 to curb #overfishing & protect global fisheries. @sebasvillasante.bsky.social#overfishing

‘Profound impacts’: record ocean heat is intensifying climate disasters, data shows www.theguardian.com/environment/... 🦑🌎🧪

🐢 Hotter temperatures produce more female sea turtles. Just a few degrees change can shift sea turtle sex ratio balances and warming climates could push populations toward extreme female bias. 🔗 https://onlinelibrary.wiley.com/doi/10.1111/gcb.70458 📷 Shane Gross @deakinuniversity.bsky.social

#BlueEconomy teaching lags behind ocean science. A review finds just 25 studies linking #OceanLiteracy to real-world economics, and the authors call for curricula that join science with careers, policy and circular economy.

At #COP30, there was growing recognition of the ocean as essential to #ClimateAction, but it remains overlooked in climate negotiations. @oceanflotilla.bsky.social#COP30#ClimateActionember Oceano Azul Foundation supports the call to include the ocean 🌊 in global climate finance and negotiations.

#SeaLevelRise could let waves reach Ahu Tongariki, the largest moai platform on Rapa Nui, by about 2080, threatening dozens of nearby cultural sites. Researchers call for community-led protection to safeguard heritage, livelihoods and tourism.

Decades of progress in protecting whales and other marine mammals are at risk as 🇺🇸 lawmakers move to weaken the Marine Mammal Protection Act and Endangered Species Act. The authors warn that this could undo recovery gains just as climate pressures grow. @science.org

2026 could be a turning point for ocean & climate action. As climate impacts mount, the ocean is more critical than ever: as a carbon sink, a source of resilience, and a provider of livelihoods. 2026 must be the year when we turn ambition into action. 🎥 IG papa_beggs

Season’s greetings from the ocean 🌊🎄 From Christmas tree worms, candy cane shrimps to jingle shells, some marine species rival our favourite holiday decorations. Which ocean creature are you this festive season? Find out in our member @mcsuk.bsky.social blog.

It's been a great year for the High Seas! ✅ Central at ocean & climate conferences ✅ 60+ ratifications & 145 signatures ✅ @earthshotprize.bsky.social win ✅ Entry into force in Jan 2026 👏 Congratulations to our member @highseasalliance.bsky.social Learn more about the High Seas ↩️

🇦🇶 Mapping reveals new 332 submarine canyon networks around #Antarctica. East Antarctica holds long, branching systems; the Peninsula has many short, steep channels, both steering water, heat and nutrients, influencing ice-shelf melt and the climate.

One of the most effective climate solutions for the ocean might be hiding beneath the waves. This episode explores kelp forests, seaforestation, and why restoring underwater forests matters now.

#COP30 delivered climate finance and adaptation progress but no #FossilFuel phase-out plan, leaving ambition far behind science. Here are some of the outcomes from the UN climate summit in Belém, Brazil. Editorial by @meghier.bsky.social and @jeff-tollefson.bsky.social#COP30↩️ #ClimateScience

🌊 Ocean matters for climate. But are countries acting? Many nations are including ocean actions in their climate plans (NDCs). However, only a few countries are showing concrete leadership with concrete, actionable goals. Analysis by @dialogueearth.bsky.social @reginalam.bsky.social

Global marine climate refugia cover 17.6 million km2, yet 70% remain unprotected. Most lie within exclusive economic zones and often span several countries, meaning expanded and coordinated protection will be needed to secure climate-resilient biodiversity networks. #MPAs

#COP30 delivered important progress in tackling #ClimateChange, but failed to address fossil fuels. Scientists, activists and the media criticised the final agreement. A @newscientist.com#COP30#ClimateChangeiece claims COPs are not "fit for purpose" and leave us only with hope for #COP31 next year.

Are current policies and pledges enough to keep global warming below 2°C? On the 10th anniversary of the #ParisAgreement, a recent Perspective shows that climate pledges outpace real action, creating a credibility gap that pushes warming toward 2°C, & calls for stronger, fairer implementation.

Glaciers don't erode simply where ice moves fastest. A survey found precipitation and elevation or length are major factors. Most glaciers remove less than 3mm of rock per year, totalling ~23 gigatonnes globally. #Glaciers2025 #IYGP2025

The International Tribunal for the Law of the Sea’s 2024 #ClimateChange opinion classifies #GHGEmissions as marine pollution and imposes due diligence. This has implications for #DeepSeaMining, pressing the ISA and sponsoring states to adopt precaution, equity and climate-risk measures.

#COP30 wrapped, falling short of expectations and ambition for #OceanClimate solutions. But experts found some bright spots alongside weighty reasons for worry in the fight against global warming. 🎤 @apnews.com#COP30#OceanClimatenterviewed them at COP30.

🪸 Vulnerable corals could be protected in deep lagoon zones in oceanic atolls. In the South China Sea, corals were seen thriving, confirming these zones could serve as climate refugia under future ocean warming. #CoralReefs #ClimateChange https://onlinelibrary.wiley.com/doi/abs/10.1111/maec.70028

How do you feel about marine #BiodiversityLoss? Experts surveying two different regions found that biodiversity loss disproportionately impacts our cultural & emotional connection to the sea. Yet, current policy fails to reflect these relational values.

High ambition on paper does not always translate to implementation. A @science.org editorial by @ndubash.bsky.social warns that rating countries’ climate pledges rewards unrealistic promises and distracts from what nations can truly deliver. #ClimateChange #ParisAgreement

The final COP30 agreement fails to even mention fossil fuels. Countries wanting to tackle climate change must not wait for the next meeting to take action

Today is #AntarcticaDay! This fragile environment is under immense pressure from human activities and urgently needs protection. Our member @antarcticasouth.bsky.social#AntarcticaDayworks to ensure strong protection for #Antarctica. Facts in our Issue Brief ⬇️
