In 2019, we found that the concept of blue carbon had begun to solidify in preceding decade around activities could achieve mitigation through conservation and restoration on ecosystems with high levels data. Five years later, available data have increased, so too are included national markets market methodologies (e.g. seaweed supratidal forests).

Natural climate solutions are crucial interventions to help countries and companies achieve their net-zero carbon emissions ambitions. Blue ecosystems such as mangroves, seagrasses, tidal marshes have attracted particular attention for ability sequester store at densities that can far exceed other ecosystems. The science of blue is now clear, there substantial interest from individuals who wish offset greenhouse gas they cannot otherwise reduce.

Coastal ecosystems can efficiently remove carbon dioxide (CO2) from the atmosphere and are thus promoted for nature-based climate change mitigation. Natural methane (CH4) emissions these may counterbalance atmospheric CO2 uptake. Still, knowledge of mechanisms sustaining such CH4 their contribution to net radiative forcing remains scarce globally prevalent macroalgae, mixed vegetation, surrounding depositional sediment habitats. Here we show that habitats emit in range 0.1 - 2.9 mg m-2 d-1 atmosphere, revealing situ macroalgae were sustained by divergent methanogenic archaea anoxic microsites.

As interest in natural capital grows and society increasingly recognizes the value of biodiversity, we must discuss how ecosystem observations to detect changes biodiversity can be sustained through collaboration across regions sectors. However, there are many barriers establishing sustaining large-scale, fine-resolution observations. First, comprehensive monitoring data on both possible anthropogenic factors lacking. Second, some situ cannot systematically established maintained locations. Third, equitable solutions sectors countries needed build a global network. Here, by examining individual cases emerging frameworks, mainly from (but not limited to) Japan, illustrate ecological science relies long-term neglecting basic our home planet further reduces chances overcoming environmental crisis. We also techniques opportunities, such as DNA citizen well using existing forgotten sites monitoring, that help overcome difficulties at large scale with fine resolution. Overall, this paper presents call action for joint factors, systematic establishment maintenance observations, network, beyond cultures, languages, economic status. hope proposed framework examples Japan serve starting point discussions collaborations among stakeholders multiple society.

Harnessing natural solutions to mitigate climate change requires an understanding of carbon fixation, flux, and sequestration across ocean habitats. Recent studies have suggested that exported seaweed particulate organic is stored within soft-sediment systems. However, very little known about how detritus disperses from coastlines, or where it may enter seabed stores, could become the target conservation efforts. Here, focusing on regionally dominant species, we surveyed environmental DNA (eDNA) coastal sediments, studied their connectivity habitats using a particle tracking model parameterized reproduce dispersal behavior based laboratory observations fragment degradation sinking. Experiments showed density changed over time, differently species. This, in turn, modified distances traveled by released fragments until they reached for first during simulations. Dispersal pathways connected shore open but, importantly, also this was reflected field eDNA evidence. Dispersion were affected hydrodynamic conditions, varying space time. Both properties timing detritus, individual each macroalgal population, short-term near-seabed medium-term water-column transport pathways, are thus seemingly important determining between potential sedimentary sinks. Studies such as one, supported further verification rates source partitioning, still needed help quantify role cycle. Such will provide vital evidence inform need develop blue mechanisms, beyond wetlands.
