The document explains that the El Niño-Southern Oscillation (ENSO) is a natural cycle of water temperature in the equatorial Pacific that drives global temperature and precipitation trends. It warns that a strong El Niño is likely by mid-summer 2026, which may boost global temperatures already elevated by human-caused climate change. The guide advises reporters to avoid storm-related terminology, consult local experts to understand regional 'teleconnections', and recognize that climate change is making ENSO swings more pronounced while ENSO simultaneously amplifies climate impacts like flooding and drought.

Colombia's 2025 NDC shifts to an absolute emissions limit for 2035, targeting between 155 and 161 million metric tons of CO2 equivalent. The plan emphasizes 'Peace with Nature' to reduce deforestation, a just transition away from fossil fuels including a roadmap by 2029, and urban decarbonization through electric mobility and black carbon reduction. However, the transition faces challenges from economic dependence on oil and coal exports and upcoming 2026 elections.

The document outlines a three-goal approach for climate finance vehicles to manage climate risk and build resilience. Goal 1 focuses on a five-step process to identify and manage physical climate hazards to align with international standards like the ISSB and Paris Agreement. Goal 2 guides the creation of an evidence-backed adaptation thesis to secure investor commitments, particularly for those targeting Multilateral Development Bank (MDB) funding. Goal 3 provides a methodology for designing impact measurement frameworks, including theories of change and indicator tables, to track resilience outcomes and avoid maladaptation.

The paper examines the 'care crisis' in Africa, where unpaid care work—primarily performed by women—is economically invisible and underfunded due to debt burdens and austerity. It proposes a shift toward 'feminist fiscal justice' by adopting progressive taxation, wealth taxes, and integrated care systems, drawing on successful models from Uruguay, Colombia, and Costa Rica.

The Páramo Wildfire Resilience Facility is a proposed financial vehicle designed to protect Colombia's high-elevation páramo ecosystems from catastrophic wildfires. It utilizes a two-pronged approach: a parametric insurance policy to provide rapid liquidity for emergency fire suppression and an adaptation and recovery trust fund for long-term risk mitigation and ecosystem restoration. The facility targets ecosystem service beneficiaries, such as water utilities and corporations, to fund these activities, aiming to safeguard the drinking water supply for millions of people in the Bogotá metropolitan area.

The report details a workshop series organized by the Inter-American Institute for Global Change Research (IAI), the Alliance for Just Deliberation on Solar Geoengineering (DSG), and The Degrees Initiative. The program focused on solar radiation modification (SRM) as a case study for emerging climate intervention techniques. Through expert presentations and a multilateral negotiation simulation in Bogotá, Colombia, the initiative aimed to bridge the gap between science and policy for officials from Latin America and the Caribbean. Key outcomes include a consensus on the need for regional research to ensure equitable participation in global forums, concerns over 'moral hazard' regarding climate mitigation, and the importance of including Indigenous Peoples and local communities in research governance.

The Inter-American Institute for Global Change Research (IAI), alongside the Alliance for Just Deliberation on Solar Geoengineering (DSG) and The Degrees Initiative, conducted a workshop series culminating in an in-person simulation in Bogota, Colombia. The program aimed to empower policymakers and technical specialists from Latin America and the Caribbean (LAC) to navigate the complexities of solar radiation modification (SRM) governance. Participants identified critical needs for regional research to understand local physical and socio-economic impacts, noting a disparity between the region's low greenhouse gas emissions and its high climate vulnerability. Discussions highlighted the risk of SRM creating a "moral hazard" that could divert attention from Paris Agreement commitments, specifically Nationally Determined Contributions (NDCs). The report emphasizes the necessity of strengthening science-policy interfaces, ensuring the participation of Indigenous Peoples through free, prior and informed consent, and fostering South-South and triangular cooperation to enhance regional data access and institutional knowledge.

The report assesses the circular economy (CE) strategies of Bogotá and Buenos Aires, identifying a common over-reliance on waste management and a lack of holistic, long-term visions. It emphasizes the critical role of the informal waste sector, which supports millions of livelihoods in the region, and advocates for their formal integration into urban governance. Key recommendations include adopting the 10-R framework to move beyond recycling toward refusing and rethinking consumption, improving waste infrastructure, and implementing extended producer responsibility (EPR) schemes.

The report details the outcomes of a WRI conference in Bogota, where teams from Brazil, Colombia, and Mexico developed a joint vision to synchronize electric mobility deployment with air quality monitoring. It proposes three primary regional projects: a 'Healthy and Sustainable Path to School' initiative to reduce child exposure to pollutants, a regional health-impact calculator platform (QueTanLimpioEsTuAire.com), and a 'Fleets in Transition' project targeting the decarbonization of urban freight. The document emphasizes a focus on vulnerable populations, including children and the elderly, and aims to position WRI as a regional leader in integrated sustainable transport solutions by 2030.

The document serves as an educational tool to explain the technical and economic aspects of Colombia's energy system and the transition toward a low-carbon economy. It distinguishes between energy sources and forms, details the electricity value chain, and explains the environmental necessity of decarbonization and 'Net-Zero' goals. The guide emphasizes that a 'just energy transition' requires both a shift in energy sources and a parallel economic transition to ensure labor reconversion and regional sustainability.

The document details the history and global expansion of Bogota's Ciclovía, a weekly event closing 127 kilometers of roads to cars. It examines how this model inspired similar programs like CicLAvia in Los Angeles, Ciclodia in Lima, and Open Streets Cape Town, highlighting their roles in promoting sustainable transport, social cohesion, and local economic growth.

The document examines policy incoherence regarding deforestation in Colombia, highlighting how vested interests in mining and agriculture, institutional rigidity, and a lack of community involvement undermine conservation efforts. While most policies show positive interactions, current mining laws and military strategies like Operation Artemisa create significant trade-offs and social conflict.

The document assesses the gap between Colombia's robust policy frameworks for the 2030 Agenda and climate goals and their actual implementation, which is hindered by conflicting priorities and institutional weaknesses. It highlights that while most land-use policies are synergistic, specific conflicts—particularly within mining legislation—and the criminalization of peasant farmers through military operations like Operation Artemisa undermine conservation efforts. The authors argue that overcoming this incoherence requires better inter-agency coordination, community engagement, and regional cooperation within the Amazon biome.

The ADAPTE project uses GIS to map the intersection of air pollution, extreme weather, and social vulnerability in Latin American cities. Findings indicate that PM10 and NOx levels in Mexico City, Santiago, and Bogota significantly exceed WHO standards. The research highlights that respiratory and cardiovascular mortality risks vary by city, season, and age group, with children in Bogota showing higher respiratory risk during cold seasons and elderly populations showing higher cardiovascular risk during the same period.

The ADAPTE project assesses how air pollution and extreme weather interact to affect human health in Mexico City, Santiago, Buenos Aires, and Bogotá. It finds that suspended particles and nitrogen oxides in these cities significantly exceed WHO standards, with respiratory and cardiovascular mortality risks varying by city, season, age, and socio-economic status.

The briefing examines the global trend of shrinking lakes and reservoirs, highlighting a study that found 53% of nearly 2,000 lakes experienced significant storage declines between 1992 and 2020. It distinguishes between anthropogenic drivers, such as unsustainable consumption seen in the Aral Sea, and climate drivers, such as increased evaporation in Mongolia. The author argues that this attribution allows policymakers to choose between demand management and behavioral changes for overuse, or infrastructure resilience and conservation for climate-driven losses.

Colombia is the third largest emitter of waste methane in Latin America and the Caribbean, with the waste sector accounting for 22% of the country's annual methane emissions. While the country has a robust regulatory framework and high collection rates, it relies heavily on landfills, many of which are nearing capacity. The report identifies significant gaps in organic waste management, data disaggregation, and financial incentives for methane mitigation, recommending the development of a national waste methane strategy and improved technical capacity at the municipal level.

The Sustainable Asset Valuation (SAVi) of Bogota's Metro Line 1 indicates the project is highly profitable, with discounted net benefits ranging from USD 2,051 million to USD 6,177 million depending on the modal shift from private transport. The assessment highlights significant added benefits in retail revenues, public health improvements from reduced air pollution and increased physical activity, and reduced traffic congestion. The project's integrated benefit-cost ratio is estimated between 1.5 and 1.9 per USD 1 invested.

The report evaluates the Bogota MRT system using the SAVi methodology, which integrates externalities like health, carbon emissions, and retail growth into a cost-benefit analysis. The analysis considers two demand scenarios (8% and 16% modal shift from private transport) over a 35-year period (2022–2058). While conventional benefit-cost ratios (BCR) are low (0.4 to 0.6), the sustainable BCR (S-BCR) ranges from 1.5 to 2.9, indicating the project is highly profitable from a societal perspective. Key benefits include significant retail revenue increases, health improvements from walking and reduced pollution, and a reduction in CO2 emissions by up to 10.79 million tonnes in the high-demand scenario.

The report applies the SAVi methodology to analyze two scenarios for Bogota's transport infrastructure: a current scenario (20102022) focusing on BRT and NMT, and a future scenario (20102058) including the MRT system. The analysis finds that while conventional benefit-cost ratios (BCR) are low (0.3 to 0.6), the sustainable BCR (S-BCR), which incorporates externalities like health, retail revenues, and CO2 emissions, is significantly higher (3.8 to 6.1). The most substantial added benefits are identified as retail revenues and property value increases, while the only negative value is the time lost due to increased walking and cycling. The report concludes that the strategy is an attractive investment that improves quality of life and supports climate targets.
