Hacia una mejor gestión de la información sobre cambio climático y conservación de la biodiversidad
The report identifies critical gaps in the management of climate and biodiversity information in the Andean region, noting that data is often too technical, fragmented, or inaccessible for policymakers. It emphasizes the need to integrate traditional local knowledge with scientific data and proposes the implementation of National Environmental Information Systems to bridge the gap between long-term scientific research and immediate political needs. Using Colombia's SIAC as an example, the authors suggest that framing biodiversity conservation through the lens of ecosystem services and social stability is more effective for securing political support and sustainable development.

Climate Change in the Midwest
The report projects substantial warming and shifting precipitation patterns for the US Midwest, with extreme heat events and heavy rainfall becoming more frequent. Under a higher emissions scenario, end-of-century temperatures could rise by up to 10°F, significantly increasing the frequency of severe heat waves and reducing snow cover. While annual precipitation may only increase slightly, winter and spring are expected to become wetter, while summer precipitation may decrease under higher emissions. These changes are projected to increase heat-related mortality and flooding risks across the region.

Understanding Future Projections
The document details the technical framework of Aqueduct's future projections, which utilize the HYPFLOWSCI6 dataset and five General Circulation Models (GCMs) to estimate water supply, use, stress, depletion, and variability. It describes three socioeconomic and climate scenarios (SSP1-RCP2.6, SSP3-RCP7.0, and SSP5-RCP8.5) with temperature projections ranging from 1.3°C to 5.7°C by 2100. The guide emphasizes that these scenarios represent different development pathways rather than simple best- or worst-case outcomes, noting that higher economic activity in optimistic scenarios can actually increase water stress. Technical processing includes spatial aggregation at the HydroBASINS Level 6 sub-basin level and temporal aggregation using 10-year trailing moving averages for the years 2030, 2050, and 2080. Limitations are noted regarding irrigation data (projected only to 2050) and livestock water demand (held constant after 2014).

Implementing Open Data Strategies for Climate Action: Suggestions And Lessons Learned for Government and Civil Society Stakeholders
The document argues that open data—datasets freely available for use and redistribution—is essential for a coordinated, whole-of-society response to climate change. It identifies five primary benefits of open data: improved data coordination and quality, more informed decision-making, the creation of novel partnerships, the democratization of climate modeling, and enhanced monitoring of policies and programs. The paper draws on a literature review, expert consultations, and pilot projects in Chile and Uruguay (conducted between August 2019 and August 2020) to provide a methodology for stakeholders to assess and improve the openness of climate-relevant datasets.

প্রতিকূল/বিরূপ আবহাওয়া এবং জলবায়ু পরিবর্তন সংক্রান্ত রিপোর্টিং সাংবাদিকদের জন্য নির্দেশিকা
The document serves as a manual for journalists to avoid common errors when linking specific weather events to climate change. It details the methodology of 'event attribution studies'—which use climate models to compare the current world with a pre-industrial one—and provides specific guidance on reporting heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires. The guide emphasizes that while climate change increases the probability and intensity of many extremes, it is rarely the sole cause, and local factors like land use and water management often play critical roles in turning a weather event into a disaster.

Human contribution to the record-breaking July 2019 heat wave in Western Europe
The study finds that the July 2019 heatwave in Western Europe was made significantly more likely and intense by human-induced climate change. In France and the Netherlands, the event would have been extremely improbable without human influence, with return periods exceeding 1,000 years. Across all analyzed locations, the heatwave was 1.5 to 3 °C hotter than it would have been in an unchanged climate. The analysis utilized a combination of observational data and eight climate model ensembles, noting that while models generally underestimate temperature trends and overestimate variability, they still simulate large probability changes.

Without human-caused climate change temperatures of 40oC in the UK would have been extremely unlikely
The 2022 UK heatwave, which saw temperatures reach 40.3°C in Coningsby, was made at least 10 times more likely by human-caused climate change. Observational analysis indicates such an event would have been about 4°C cooler in pre-industrial times, though climate models systematically underestimate this trend. The event had significant impacts on human health, with projected excess mortality of over 840 people in England and Wales, and exposed critical vulnerabilities in UK infrastructure and urban planning.
