Blue carbon ecosystems, including mangroves, seagrass meadows, and salt marshes, are critical natural climate solutions that sequester over 50% of global ocean carbon despite covering only 0.5% of the sea floor. These habitats support 3 billion people through food security and protection from extreme weather, yet they face severe degradation, with 67% of mangroves already lost or degraded. Protecting these ecosystems could prevent 304 Tg of carbon dioxide emissions annually, while restoration could sequester an additional 841 Tg, totaling approximately 3% of annual global GHG emissions. However, as of 2023, only 61 of 151 countries with these habitats included their conservation in their Nationally Determined Contributions (NDCs).

The Green Climate Fund (GCF) proposal, implemented by the UNDP, seeks USD 103.25 million in grants to advance the 'Early Warnings for All' (EW4All) initiative across seven vulnerable countries. The project focuses on four pillars: disaster risk knowledge, observation and forecasting, warning dissemination, and preparedness and response. It aims to reach millions of direct and indirect beneficiaries by upgrading hydrometeorological infrastructure, implementing AI-driven forecasting, and establishing inclusive, last-mile communication protocols, with a strong emphasis on gender and disability inclusion.

The report examines how a 21.8% rate hike for State Farm homeowners insurance in California, approved in March 2025 following devastating wildfires in Los Angeles, disproportionately affects policyholders in high-risk areas. It projects that the average State Farm policyholder in California will pay $841 more in 2025 than in 2023, with some communities seeing premiums more than double. The analysis highlights that 280,000 policyholders across 122 communities will face annual premium increases of $1,000 or more. The document argues that these escalating costs are a direct result of climate change and suggests that the financial burden should shift from policyholders to the oil and gas companies responsible for fossil fuel pollution.

A May 2025 survey of 1,040 U.S. adults shows that 69% believe global warming is happening, with 60% attributing it primarily to human causes. While 65% of Americans express worry and 61% feel a personal responsibility to help, social engagement remains low, as 65% rarely or never discuss the issue with family and friends. A majority of respondents perceive global warming as currently harming people in the U.S. and affecting various extreme weather events, including extreme heat (75%) and wildfires (72%). Despite these concerns, 53% disagree that new technologies can solve the problem without significant individual lifestyle changes, and 55% believe individual actions make a difference.

The report provides a comprehensive climate risk profile for Fiji, detailing observed and projected climatic changes, specific hazards such as tropical cyclones and sea-level rise, and their impacts on target communities and ecosystems. It emphasizes the disproportionate vulnerability of women and marginalized groups and recommends specific nature-based solutions (NbS) and gender-responsive measures to enhance climate resilience across six districts: Kubulau, Dawasamu, Nakorotubu, Namalata, Bua, and Bureta.

Egypt's Fourth National Communication details the country's climate vulnerabilities, particularly regarding water scarcity and sea-level rise, and outlines a strategic framework to reduce greenhouse gas emissions by 24% by 2030 compared to business-as-usual levels. The report emphasizes a transition toward a green economy through the Integrated Sustainable Energy Strategy 2035, aiming for a 42% share of renewables by 2035, and the implementation of extensive adaptation measures in agriculture, coastal zones, and public health. It also highlights the critical impact of the Grand Ethiopian Renaissance Dam (GERD) on water security and the need for enhanced international climate finance and technology transfer.

The Union of Concerned Scientists finds that the 122 largest fossil fuel and cement producers, termed 'Carbon Majors', are responsible for nearly half of present-day surface temperature increases and nearly one-third of observed global mean sea level rise. The research indicates that past emissions from these entities have already guaranteed an additional 10 to 22 inches of sea level rise by 2300. The document argues that these corporations knowingly misled the public and obstructed climate policy, and it advocates for using legal pathways and multilateral negotiations to hold them financially and legally responsible for climate damages, particularly for vulnerable island nations.

The document outlines eight systemic challenges in climate-related mobility, including the risks of simplistic conflict narratives, the instrumentalization of migration as adaptation, and the impact of slow-onset events. It emphasizes the need for rights-based frameworks, inclusive governance, and the recognition of colonial legacies to address these inequities. To tackle these issues, SEI focuses on three priority areas: managing transboundary climate impacts, conducting grounded research to shift power dynamics (such as through the HABITABLE project), and strengthening global cooperation for sustainable livelihoods using tools like AidAtlas and Trase.

The document highlights the 2025 International Year of Glaciers' Preservation, detailing how human-caused climate change is accelerating glacial melt. It emphasizes the role of glaciers as 'water towers' providing freshwater for billions and warns of increasing risks from glacial lake outburst floods (GLOFs), particularly in Asia and the Americas. The text notes that glaciers in 50 UNESCO World Heritage sites are losing an average of 58 billion tonnes of ice annually, with a third projected to vanish within 25 years.

The document outlines the critical role of oceans in absorbing heat and carbon, the resulting environmental and socioeconomic crises, and offers strategic advice for journalists to improve the depth and justice-orientation of ocean reporting.

The document outlines the environmental and socioeconomic impacts of ocean warming and acidification, while offering strategic advice for journalists to move beyond reactive coverage toward sustained, justice-oriented reporting on marine ecosystems.

The research describes the evolution of a 430 km delta front in southern Buenos Aires Province, which was most active around 9,000 calibrated years BP. While the Colorado and Negro rivers once contributed to a large delta system when sea levels were significantly lower, current conditions have left only a minor remnant delta for the Colorado River and an estuary for the Negro River.

The research establishes a new breaching protocol for the sand barrier at Laguna de Rocha, Uruguay, replacing artificial opening practices that began in the 1950s and may have caused negative physical and biological effects since the 1980s. The protocol uses indicators such as water depth, sand barrier berm elevation, and rainfall forecasts to guide management decisions. The process relied on a participatory advisory group active for over 15 years to reach a consensus among scientists, authorities, and local stakeholders.

The proposal seeks USD 1,000,000 over 24 months to address Nauru's vulnerability to sea-level rise and temperature increases. It focuses on moving from incremental to transformative climate action through community-led visioning workshops, technical studies on public health, soil restoration, and livestock, and the development of a GCF Concept Note for agri-food systems.

This report by the Stockholm Environment Institute (SEI) examines the complex nexus of climate change, migration, and justice. It argues that climate change acts as a risk multiplier that interacts with socio-economic and political factors rather than being a sole driver of migration. The document identifies eight key challenges—including the oversimplification of the climate-conflict-migration link, the risks of instrumentalizing migration as adaptation, and the impacts of slow-onset events—and proposes interdisciplinary, rights-based solutions. SEI highlights its strengths in analyzing transboundary climate impacts, conducting grounded comparative research to shift power dynamics, and fostering global cooperation for sustainable livelihoods through tools like AidAtlas and Trase.

The report argues that offshore oil and gas activities pose severe threats to the global commons, specifically the oceans and atmosphere. It details how seismic surveys harm marine life, production leads to catastrophic blowouts and underreported methane emissions, transportation increases the risk of spills and invasive species, and improper decommissioning leaves a legacy of leaking 'orphan' wells. The document emphasizes that these risks are magnified by climate change and that existing legal frameworks, including UNCLOS and the polluter pays principle, should be leveraged to phase out offshore fossil fuel extraction.

The document details the hazards of offshore oil and gas transportation, highlighting that 40 percent of maritime trade involves fossil fuels. It argues that the expansion of this sector, particularly liquefied natural gas (LNG), increases greenhouse gas emissions, the risk of catastrophic oil spills, and the spread of invasive species. The report emphasizes that climate change creates a feedback loop, where extreme weather and sea-level rise heighten the likelihood of infrastructure failure and subsequent ecological disasters.

The report details how climate change is increasing the frequency and severity of extreme weather in Oregon, leading to significant economic losses and infrastructure needs. Key risks include intense heatwaves, devastating wildfires, disrupted water supplies for agriculture, and coastal flooding. The document provides specific cost estimates for adaptations, such as school air conditioning and coastal protection, while outlining the broader systemic risks to public health, fisheries, and the state's $5.7 billion agricultural industry.

The report details how Los Angeles County is affected by severe storms, rising sea levels, temperature extremes, and extreme drought. It highlights that flood risk threatens 27% of buildings in the city of Los Angeles and that the county spent 64% of the last 23 years in drought. The document provides extensive lists of potential costs, including infrastructure projects like seawalls, energy efficiency retrofits, and water treatment updates, while noting that disadvantaged populations are disproportionately exposed to flood risks.

Maryland is experiencing accelerating climate risks, including rising sea levels, more frequent extreme precipitation, intensified droughts, and increasing temperature extremes. These changes are causing significant land loss, infrastructure damage, and public health crises, necessitating costly adaptation measures such as seawalls, flood-proofing, and cooling systems.
