This paper maps the epistemic geography of the mitigation working group (WGIII) of the Intergovernmental Panel on Climate Change (IPCC). It thus contributes to the study of the science-policy interface of the IPCC and its authors. We mapped the WGIII authors' scientific publications and created visual networks based on bibliographic coupling of the IPCC authors of Assessment Reports 2-6. We found that, over time, the scientific community behind integrated assessment models (IAMs) has gained greater prominence in the epistemic geography, and today most of the IPCC WGIII authors rely on IAMs as a way to analyze the impacts of mitigation efforts. Subsequently, we discuss the consequences of this development for climate knowledge, climate policy, and the crowding out of other relevant academic approaches, theories, and qualitative data. We conclude by suggesting a more comprehensive approach to the methodological approaches in the IPCC assessments.
The construction industry, which accounts for 37 % of global greenhouse gas emissions (GHGe), is a crucial sector in which efforts must be made to mitigate such emissions. Understanding future resource demand and related GHGe is essential to pinpointing where these efforts must be concentrated. Based on Denmark, this study aims to estimate future resource consumption and GHGe caused by new buildings annually between 2024 and 2050 and to identify hotspots where mitigation efforts should be focused. Combining spatiotemporal predictions of new construction with life cycle assessments (LCA) of 289 buildings' GHGe, it is found that an average of 6.6 million m2 of new buildings are expected to be constructed yearly. This results in an annual use of 7 million tons of resources, i.e., building materials, varying between 2.1 and 13.8 million tons, and the emission of 3 million tons of CO2e, ranging between 1.5 and 5 million tons. Overall, 91 % of future GHGe is related to embodied emissions. Moreover, of all the new construction considered in the study, residential and office buildings will be responsible for 78.4 % of annual resources and 76.5 % of GHGe between 2024 and 2050. Identified hotspots reveal that mitigation efforts must focus on building-envelope elements for all building typologies, such as roofs, walls, and slabs. Also, three main types of material - mineral products, steel, and insulation materials - contribute significantly to GHGe, indicating the necessity of focusing mitigation on these products in the future.
The extensive shoreline of Mexico is heterogeneous and diverse, but it is increasingly exposed to degradation and loss. This is the first study performed at a national level and with a multidisciplinary approach, that aims to assess the impact of climate change and human-related pressures affecting Mexican coasts. From 1863 to 2022, 386 tropical cyclones have landed on Mexican coasts, six of them of category 5 (most on the Atlantic). Sea level rise projections showed that the Atlantic coast is the most vulnerable, whereas intense coastal erosion ( > 25m/year) is more widespread on the northern Pacific coast. Human impacts include coastal urbanization, ecosystem degradation and coastal armouring. Six million people live on Mexican coasts, mostly in the Caribbean. Mangroves and coastal dunes each cover nearly 800,000 ha. The mangroves are relatively well preserved, but almost half the area of the coastal dunes is degraded. Coastal armouring is widespread along the coasts, but most of these structures (55%) are found on the Yucatan peninsula. Activities required to improve the condition of Mexican coasts and make them a sustainable place to live would include: adaptation of human settlements to the conditions of the dynamic coasts; appropriate coastal protection measures that do not induce downdrift erosion; dealing with coastal risks by restoring and preserving coastal ecosystems.
As regulations for buildings become increasingly stringent, Life Cycle Assessment (LCA) is emerging as a key method of documenting and reducing embodied greenhouse gas emissions (GHGe). Mitigation strategies often focus on optimizing material quantities or substituting conventional materials with low-carbon alternatives. However, these approaches are typically applied in isolation and to specific building components. This study examines which mitigation strategies should be prioritized to reduce embodied GHGe at the whole-building level while ensuring compliance with regulatory limits for new construction in Denmark. Using data from 172 residential buildings and 1054 Environmental Product Declarations (EPDs) across 21 material categories, Monte Carlo Simulations were employed to generate LCAs by combining real buildings' material intensity coefficients (MICs) with EPD data. The results indicate a 66 % probability of compliance with the regulatory limit values for row houses and 64 % for multi-family buildings, but only 15 % for single-family homes. Sensitivity analyses across material categories identified key contributors to both total embodied emissions and variability, such as mineral boards and ready-mixed concrete. This highlights areas where mitigation efforts should be concentrated, either by selecting lower-impact materials or by reducing material quantities. The findings suggest that prioritizing reductions in material quantities may be the most effective approach, though low-carbon materials remain a crucial strategy. These results provide valuable insights for making informed material choices early in the design process and offer strategies for improving life cycle embodied GHGe in line with regulatory compliance for building projects.
Thanks to the drive and foresight of Ji & rcaron;& iacute; Lom and Franti & scaron;ek Moravec, the International Symposium on Fish Parasites' (ISFP) history started in 1983 when they convened a meeting of academics coming from both sides of the Iron Curtain, which took place at & Ccaron;esk & eacute; Bud & ecaron;jovice, Czechoslovakia. Now on its eleventh iteration, XI ISFP was hosted by the Autonomous University of Yucat & aacute;n in M & eacute;rida, Mexico from 20 to 24 January 2025. The meeting had five invited plenary talks and was organized into six thematic areas plus two workshops, one on Acanthocephala, the other a horizon-scanning exercise to identify research needs and priorities in fish parasitology. In this TrendsTalk, we invited the XI ISFP local organizing committee to summarize the highlights of the meeting.
