The Changing Markets Foundation argues that the EU's Vision 2040 for Fisheries and Aquaculture must address the structural unsustainability of carnivorous aquaculture. The organization highlights how the reliance on fishmeal and fish oil (FMFO) derived from wild fisheries increases pressure on marine ecosystems and undermines food security in regions such as West Africa, India, Vietnam, Peru, and Senegal. It advocates for a policy shift that prioritizes Low Trophic Aquaculture (LTA)—such as seaweed and bivalve farming—over carnivorous finfish production, while calling for the phasing out of marine ingredients in feed and improved transparency regarding total wild fish inputs in supply chains.

The document examines 58 active fossil fuel production restrictions across 25 countries and 27 subnational jurisdictions, noting a sharp increase in such policies since the 2010s. It highlights that while these measures are expanding, they remain politically fragile and susceptible to rollbacks during high energy price cycles or government changes. The analysis emphasizes the role of subnational governments as early adopters and the importance of strong legal anchoring to prevent repeals.

The report argues that South Africa must elevate the Southern Ocean and Antarctica in its strategic planning, as the region is critical for global climate regulation, food security, and maritime safety. While South Africa is the only African state party to the Antarctic Treaty, its diplomatic engagement has been inconsistent. The document highlights rising risks from climate change, such as sea-level rise threatening African coasts, and geopolitical tensions, including Russia's seismic surveying and the blocking of Marine Protected Areas by China and Russia. It suggests South Africa leverage its non-claimant status and role as a logistical gateway to enhance its influence, while warning that its under-resourced navy may struggle with increasing search and rescue demands from growing Antarctic tourism and rerouted shipping traffic around the Cape of Good Hope.

The document examines the health and economic impacts of per- and polyfluoroalkyl substances (PFAS), known as "forever chemicals," and advocates for a categorical regulatory approach. It highlights that current U.S. efforts, such as EPA drinking water limits, are insufficient because manufacturers can replace banned individual PFAS with other similar chemicals. The brief notes that annual health damages in the U.S. are estimated between $920.91 million and $62.6 billion across different studies, though these are likely underestimates. While cleanup technologies for water exist, those for soil and air remain undeveloped, making restrictions and bans the most cost-effective way to address ongoing contamination.

The report analyzes maritime security in the Western Indian Ocean (WIO), emphasizing that threats like climate change, illegal fishing, and piracy are interconnected. It highlights the risks of increasing militarisation by global powers and the environmental dangers of rerouting shipping around the Cape of Good Hope due to Red Sea instability.

The document advises climate reporters to humanize scientific research, avoid hyperbolic language, and vet sources to prevent the spread of low-quality or overgeneralized findings. It highlights the risk of predatory journals and provides a curated list of tools and journals for verifying research.

The report establishes a methodology for mapping superhot rock (SHR) geothermal resources globally, defining SHR as heat from subsurface formations exceeding 374°C. Using the LithoRef18 global reference model and a 'hydrothermal proxy' to account for non-steady-state heat flow, the study estimates the un-risked global resource. For depths of 4-8 km ('today's resource'), the estimated potential is 3,272 GWe (13,895 GWth). For depths of 8-12.5 km ('tomorrow's resource'), the potential increases to 59,930 GWe (245,581 GWth). The analysis identifies 125 countries with SHR potential, with significant resources in the US, China, Indonesia, and others. The report also analyzes flow rate uncertainties using a database of 33 petrothermal projects, determining a P50 flow rate of 55 l/s for its calculations.

Chile has proposed that the Climate Science and Resilience Center (CR2) be admitted as an Associate of the Inter-American Institute for Global Change Research (IAI). The proposal highlights CR2's regional research ambitions in South America and Antarctica, its interdisciplinary approach to bridging natural and social sciences, and its contributions to Chilean public policy, including the 2022 Framework Law on Climate Change and the design of Chile's NDC for COP25. Additionally, CR2's leadership in climate services is noted through the creation of the Climate Risk Atlas of Chile (ARClim) and 14 other open-access climate services.

The document describes the ocean as the planet's largest carbon sink, sequestering approximately 26% of human-released CO2 annually. It details the biological and physical carbon pumps, the role of large marine mammals and coastal ecosystems in 'blue carbon' storage, and evaluates emerging geoengineering approaches for carbon dioxide removal (CDR). The brief emphasizes that while ocean-based solutions build resilience and biodiversity, they must be paired with rapid emissions cuts to effectively slow global warming.

The report assesses the current state of spatial management in the Southern Ocean, highlighting the tension between CCAMLR's conservation mandate and the 'rational use' of marine resources. It identifies a deadlock in the establishment of new Marine Protected Areas (MPAs) due to eroding consensus and geopolitical tensions. The authors suggest transitioning from a narrow focus on MPA designation toward a comprehensive Marine Spatial Planning (MSP) approach to better integrate land-sea conservation and respond to climate change impacts.

The report argues that the EU's Restrictions Roadmap is failing to meet its ambition of creating a 'non-toxic environment' due to narrow chemical grouping, excessive industry derogations, and systemic regulatory delays. While the roadmap provides a list of priorities, the authors find that most current restriction initiatives are too limited in scope to effectively tackle the risks of hazardous substances like bisphenols and PFAS.

The document defines carbon accounting as the practice of quantifying and reporting greenhouse gas emissions to set reduction targets. It traces the evolution of environmental reporting from the 1987 Montreal Protocol and the 1997 Kyoto Protocol to the establishment of the Greenhouse Gas Protocol. The text distinguishes between attributional accounting, which identifies where emissions occur, and consequential accounting, which measures system-wide changes resulting from specific actions. It argues that while attributional accounting is standard, organizations must adopt both methods in tandem and move toward near real-time assessments to effectively implement climate commitments and legislation like the US Inflation Reduction Act.

This fact sheet explains the formation and types of glaciers, the drivers and consequences of their melting due to global warming, and the importance of legal protections for these freshwater reserves, highlighting Argentina's National Glacier Law.

The report argues that krill fishing is inherently unsustainable as it threatens a fragile ecosystem already stressed by climate change. It highlights the dominance of Aker BioMarine in the market and identifies numerous European retailers selling salmon fed with krill meal. The document criticizes the Marine Stewardship Council (MSC) certification for ignoring climate change effects and calls for an immediate moratorium on krill fishing.

The report details how krill fishing, dominated by Aker BioMarine, exacerbates climate-driven threats to the Antarctic ecosystem by competing with key predators for food. It exposes a lack of transparency in supply chains, where krill meal is used in aquaculture feeds sold by major European retailers, and krill oil is widely sold as dietary supplements. The document criticizes the Marine Stewardship Council (MSC) certification for ignoring climate change and predator impacts, and calls for an immediate moratorium on krill fishing.

The report argues that Antarctic krill fishing is unsustainable, threatening a fragile ecosystem already stressed by climate change. It highlights how the industry, dominated by Aker BioMarine, uses greenwashing and problematic certifications like the MSC to justify its operations. An investigation reveals that krill-oil supplements are widely sold by the world's largest retailers and krill meal is extensively used in European salmon aquaculture, often without consumer-facing labels or retailer policies to exclude it.

The briefing analyzes the Biden Administration's 2021 climate security reports, identifying climate change as a 'shaping threat' that necessitates a reexamination of national security assumptions. It argues that climate risks are current and future, wide-ranging, and exacerbate other security concerns, particularly in competition with China. The authors propose five 2022 priorities: mainstreaming climate security in regional strategies, linking adaptation with conflict prevention, maximizing whole-of-government science collaboration, increasing support for allies, and utilizing strategic foresight for worst-case scenarios.

The policy brief examines the environmental and social costs of mining, the limitations of international and domestic governance, and the potential for public-private partnerships and the UN Sustainable Development Goals to create more sustainable mining practices.

The document highlights the Montreal Protocol as a successful model of multilateralism where science, diplomacy, and the private sector collaborated to phase out ozone-depleting substances (ODS). It details how the Protocol and its amendments, including the Kigali Amendment, have prevented millions of skin cancer cases and cataracts while providing significant climate co-benefits by reducing greenhouse gas emissions. The brief emphasizes the importance of differentiated responsibilities for developing countries and the role of political will and industry cooperation in achieving global environmental goals.

The study analyzes the EDML ice core to understand how air bubbles transition into clathrates under hydrostatic pressure. By using digital image processing and pseudocolor transformations, the researchers identified distinct zones of ice: a bubble-only region (80–700 m), a transition region (700–1250 m), and a clathrate-only region (1250–2774 m). The findings demonstrate that 'cloudy bands' (CB), associated with higher atmospheric dust concentrations from summer precipitation, exhibit greater porosity variations and a faster transition to clathrates than 'clear ice' (CI) from winter precipitation. In the deepest sections, 'white dots' (clathrate aggregates) maintain a spatial distribution and concentration proportional to the original bubbles, confirming a continuity in the evolution of the ice structure.
