Toxic tides of change: Ocean pollution as a cultural tipping point - Ambio This paper offers a new perspective on the valuation of the impacts of industrial ocean pollution. Rising levels of industrial pollutants have a profound impact on marine resource-dependent peoples, p...

What is a cultural tipping point?

The current pollution governance undervalues cultural losses.

Authors of this study suggest integrating cultural health and holding state & corporate actors responsible for harm.

Microplastics primarily provide habitats for benthic microalgae in Fujian coastal waters of China Environmental science; Pollution; Aquatic science; Microbiology; Aquatic biology

In China’s Fujian coastal bays, microplastics host mainly benthic microalgae, allowing them to thrive in surface waters where they normally wouldn’t.

These “plastic habitats” could alter marine food webs and nutrient cycling, underscoring the ecological risks of rising #PlasticPollution.

A new report by UNESCO IOC reveals a critical lack of understanding of how the ocean absorbs and stores carbon.

This has major implications for future emission targets and national climate plans. #ClimateChange

This ocean narrative calls for reinforced ocean observing systems, improved uncertainties, and robust science-based information for ocean protection policies and actions.

Global ocean change in the era of the triple planetary crisis Abstract. This ocean narrative is grounded in global ocean indicators and framed around climate, biodiversity, and sustainable development. In 2024, global ocean heat content (OHC) reached record leve...

Last year's @copernicusmarine.bsky.social Ocean State Report showed record ocean heat, sea-level rise, and acidification, revealing a planet under mounting stress.

These trends, tied to climate change, pollution & biodiversity loss, threaten marine life and the ocean’s role in climate stability.

New UN rules on carbon trading could weaken #ClimateAction!

Without urgent reforms, emissions trading under the #ParisAgreement risks delaying real emissions reductions rather than delivering them.

Climate change is reshaping the Winter Olympic Games Cortina d’Ampezzo records almost one-fifth fewer freezing days annually compared with those in decade after 1956 Games

What do the #WinterOlympics have to do with the ocean? You might be surprised.

Snow and ice are part of the global water system connected to the ocean. The ocean also regulates the climate that makes winter sports possible.

Even the Winter Games tell an ocean story. #MilanoCortina2026

Ocean literacy is key to understanding and protecting our planet. There is only one ocean and our language should reflect this.
