Between 1995 and 2020, Ethiopia's comprehensive wealth grew at an average annual rate of 3.3%, with human capital serving as the primary driver. However, real per capita wealth declined in 2018/19 and 2019/20, coinciding with increasing environmental pressures on ecosystems and climate.

An analysis of 476 weather stations from 1973 to 2023 shows that fire weather seasons are lengthening and intensifying across the contiguous United States, with the most significant increases occurring in the West. While the East has seen more modest increases, both regions are experiencing a notable rise in fire weather days during the spring. The Southwest has seen the most dramatic growth, with some areas experiencing fire weather twice as often as they did 50 years ago.

The document describes La Niña as the cool phase of the El Niño-Southern Oscillation (ENSO) cycle, characterized by the movement of cold water to the central and eastern Pacific surface. For 2024, there is an 85% chance of a transition to neutral conditions between April and June, and a 60% chance of La Niña developing by June to August. The text highlights that multi-year La Niña events are increasing in frequency, with five of the last ten occurring in the past 25 years. While La Niña temporarily lowers global average surface temperatures by about 0.1C, it does not offset human-caused warming; recent La Niña years have been among the top 10 hottest years ever. Regional impacts include drier conditions in East Africa and the southern US, and wetter conditions in Southeast Asia, India, and northern South America, affecting various crop yields and increasing the risk of floods and droughts.

Florida is expected to experience dangerous early-season heat from May 14-16, 2024, with temperatures exceeding 90°F and heat index values between 100°F and 105°F. Human-caused climate change has made these conditions more than five times more likely, as indicated by a Climate Shift Index (CSI) level of 5 in Central and Southern Florida. Approximately 17 million people are expected to experience at least one day of CSI level 5 heat. The event is characterized by high humidity and overnight lows 5°-10°F above average, increasing the risk of heat-related illnesses and mortality, particularly for those without effective cooling.

The document addresses the humanitarian and environmental crisis caused by record-breaking rainfall in Rio Grande do Sul, Brazil, affecting nearly 1.5 million people. It attributes the severity of the disaster to both global greenhouse gas emissions from wealthy nations and domestic failures, including the dismantling of environmental legislation and a lack of integrated disaster management. The author advocates for a transition from 20th-century concrete infrastructure to 21st-century nature-based solutions and integrated urban land use management to enhance climate resilience.

The Canadian Association of Physicians for the Environment (CAPE) and other health professionals are calling on the government of New Brunswick to ban hydraulic fracturing (fracking) due to significant risks to human health. Citing a range of scientific studies, the authors link fracking to adverse birth outcomes, increased mortality, and higher rates of cancer and respiratory diseases. They also warn that LNG infrastructure releases dangerous pollutants and contributes to climate change, which they identify as the leading global threat to human health.

The petition argues that the Upstream Petroleum Resources Development Bill (B13B – 2021) violates the South African Constitution and the One Environmental System (OES). It highlights the Bill's failure to provide adequate local economic development frameworks, its acceleration of fossil fuel extraction during a climate emergency, and its insufficient public participation and consultation processes. The petitioners urge the President to refer the Bill back to Parliament for redrafting to align with human rights and climate science.

Over 400 civil society organizations are calling on the Council of Europe to establish a binding legal framework for the right to a healthy environment. While 42 of the 46 Member States already protect this right via national laws or the Aarhus Convention, the European Convention on Human Rights lacks an explicit autonomous right. The authors argue that an additional protocol would provide legal clarity for the European Court of Human Rights, protect environmental defenders, and address the 'triple planetary crisis' of pollution, climate change, and biodiversity loss.

The document argues that the EU's ecological footprint is unsustainable, noting that the region uses between 70% and 97% of the world's 'safe operating space' despite having less than 6% of the global population. The authors call for the acceleration of the European Green Deal, increased public investment in climate and social goals, and strengthened civil society participation to avoid ecological collapse and economic instability.

The document marks the 2024 EU Earth Overshoot Day, noting that the EU exhausted its nature budget for the year on May 3, 2024. It urges EU leaders to make the triple planetary crisis of climate change, biodiversity loss, and pollution a major political priority ahead of the European elections, citing the devastating impacts of climate-related events on health, economies, and social justice.

The document provides a comprehensive historical record of the Inter-American Institute for Global Change Research (IAI) governance from 1997 to 2024. Key institutional developments include the adoption of the 2024-2030 Strategic Plan, the creation of the Science Diplomacy Center, and the implementation of Gender, Equity, Diversity, and Inclusion (EDI) policies. The records track the evolution of the IAI's scientific focus, including the establishment of research programs on the nexus of climate, environment, and health, as well as oceans and coastal systems. Administratively, the document details the transition of the IAI headquarters from Uruguay to Panama, the approval of annual core budgets, and the expansion of the institute's network through the invitation of various academic and research institutions as Associates.

The report argues that GDP is an insufficient measure of national success because it ignores the depletion of assets and non-market well-being. By analyzing data from 1995 to 2020 for Ethiopia, Indonesia, and Trinidad and Tobago, the study demonstrates that comprehensive wealth (CW)—which includes natural, human, social, produced, and financial capital—reveals critical sustainability trends invisible to GDP. Key findings include the unsustainable depletion of fossil fuel assets in Trinidad and Tobago, the inefficient management of natural capital in Indonesia, and the critical need for increased agricultural productivity and wealth accumulation in Ethiopia.

The report examines the environmental and health risks associated with ASGM tailings, which often contain mercury and cyanide. It finds that while large-scale mining (LSM) has robust standards, ASGM lacks specific international and regional tailings governance, relying on general mining codes that are often poorly enforced due to sector informality. The document recommends the creation of an international ASM-specific tailings standard, the implementation of strategic environmental assessments (SEAs), and the development of formalization schemes to improve waste management and recover critical minerals from tailings.

The report evaluates the African Union Peace and Security Council (PSC) as it marks 20 years of operation, critiquing its tendency toward ceremonialism over deep expert reflection. It analyzes UN Resolution 2719, which allows AU-led peace support operations to access UN-assessed contributions, specifically discussing its potential application in Somalia, the DRC, and Sudan. Additionally, it urges stronger continental coordination for the UN's Pact for the Future and argues that the AU should leverage its diplomatic position to mediate the Israel-Hamas conflict to protect Africa's economic stability and global influence.

The 2024 update of the Living Planet Index for migratory freshwater fishes reveals a catastrophic global decline of 81% in population abundance from 1970 to 2020. The report identifies habitat degradation, loss, and overexploitation as the primary drivers of these declines, with the most severe regional losses occurring in Latin America & Caribbean (-91%) and Europe (-75%). While managed populations declined less than unmanaged ones, the report highlights a mismatch between the prevalence of habitat-related threats and the dominance of fisheries-focused management.

Between 2000 and 2023, 80% of major U.S. power outages were caused by weather, with a significant increase in frequency during the last decade. Severe weather, winter storms, and tropical cyclones are the primary drivers, with Texas and the Southeast region among the most affected. The document highlights the vulnerability of aging infrastructure and the disproportionate impact on marginalized and medically vulnerable populations, while suggesting grid hardening, microgrids, and emissions reductions as paths toward resilience.

The document highlights the severe economic and health costs of black carbon, noting that in China, short-term exposure in 2017 cost over US$7.5 billion and long-term exposure over US$53 billion. It asserts that reducing black carbon is a "triple win" that would protect glaciers, save millions of lives—including over 400,000 annually in India and nearly half a million in Sub-Saharan Africa—and improve gender equality by reducing the US$800 billion annual loss in women's productivity caused by unclean cooking fuels. Despite these benefits, the author notes that only 12 countries included black carbon targets in their first Nationally Determined Contributions (NDCs), and warns that transportation-related emissions in Africa could double by 2040.

The paper evaluates the quality of six major global scenario sets using scenario diversity analysis, a quantitative method designed to assess how well a set of scenarios covers the space of future possibilities. While the results indicate that the assessed sets perform relatively well in terms of diversity, the authors highlight a potential trade-off between the breadth of future possibilities covered and the introduction of redundancy within the sets, particularly when using classic scenario architecture methods.

This briefing document, prepared by the IAI Directorate, presents the report of the 2024 Extraordinary Meeting of the Conference of the Parties (CoP) to the Inter-American Institute for Global Change Research (IAI). The primary purpose of the meeting, held via videoconference on 26 March 2024, was to review and decide upon a proposal from Panama to host the headquarters of the IAI Directorate.

The document argues that climate change is a critical electoral issue in the 2024 US elections and urges journalists to move beyond 'red-blue' political binaries to report on the scientific consensus and local impacts. It provides specific questioning frameworks for candidates, methods for debunking common climate myths, and suggestions for localizing climate stories across sectors like infrastructure, housing, and energy. The guide emphasizes that reporting on the climate crisis is a matter of professional journalism rather than activism, citing the role of the press in holding power accountable during historical crises.
