The plethora of available projections presents end users with the challenge of how to select climate projections, known as the “practitioner's dilemma.” In addition, if an end-user determines that existing projections cannot be used, then they face the additional challenge of producing climate projections for their region that are useful for their needs. We present a methodology with novel features to address the “practitioner's dilemma” for generating downscaled climate projections for specific applications. We use the Edwards Aquifer region (EAR) in south-central Texas to demonstrate a process to select a subset of global climate models from both the CMIP5 and CMIP6 ensembles, followed by downscaling and verification of the accuracy of downscaled data against historical data. The results show that average precipitation changes range from a decrease of 10.4 mm to an increase of 25.6 mm, average temperature increases from 2.0°C to 4.3°C, and the number of days exceeding 37.8°C (100°F) increase by 35–70 days annually by the end of century. The findings enhance our understanding of the potential impacts of climate change on the EAR, essential for developing effective regional management strategies. Additionally, the results provide valuable scenario-based projected data to be used for groundwater and spring flow modeling and present a clearly documented example addressing the “practitioner's dilemma” in the EAR.</p>","PeriodicalId":48748,"journal":{"name":"Earths Future","volume":"12 10","pages":""},"PeriodicalIF":7.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2024EF004716","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142404543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use natural language processing, based on a new climate hazard taxonomy, to review, identify, and geolocate out of 100 million abstracts those that deal with hydro-hazards. We find that the spatial distribution of study areas is mostly defined by human activity, national wealth, data availability, and population distribution. Hydro-hazard events that impact large numbers of people lead to increased research activity, but with a strong disparity between low- and high-income countries. We find that 100 times more people need to be affected by hazards before low-income countries reach comparable research activity to high-income countries. This “Wealth over Woe” bias needs to be addressed by enabling and targeting research on hydro-hazards in highly impacted and under-researched regions, or in those sufficiently socio-hydrologically similar.

Nevertheless, their efficacy is impeded by a dearth of research. To mitigate these constraints, this study introduces a comprehensive and integrated framework for appraising biodiversity credits. Drawing upon the Emergy Accounting methodology, the framework encompasses four key perspectives: Emergy-based Ecosystem Potential (EEP), Emergy-based Ecosystem Network (EEN), Emergy-based “Species' to Human” contributions (ESH), and Emergy-based Species' Significance. Furthermore, this study scrutinizes the trajectory of biodiversity credits across 31 provinces spanning from 2000 to 2050, considering 220 distinct scenarios. The findings reveal that China has attained the no net loss (NNL) objective concerning conventional area-based conservation targets, with forest cover encompassing 27% of the total land area. However, biodiversity credits at the ecosystem level exhibit an escalating trend, with growth rates ranging from 0.73% to 1.0%, while credits at the species level depict a decremental trend, with an approximate growth rate of −0.21%. Under a scenario of moderate growth, projections for the year 2030 indicate that the EEP credit is poised to accrue approximately 4.76E + 20 solar emjoules (sej), the EEN credit is forecasted to accumulate around 1.03E + 21 sej, and the ESH credit is anticipated to decline by 1.46E + 23 sej within the context of the NNL paradigm.

To date, economic assessments of adaptive decision-making that take into account future learning about sea level rise uncertainty are rare and the existing ones have relied on simple quantification of future learning not validated against sea level science. To address this gap, we develop an economic adaptive decision-making framework that takes into account future learning about sea level rise uncertainty and apply it to a coastal case study in Lübeck, Germany, to answer the question of how adaptation to sea level rise can be improved through adaptive adaptation pathways as opposed to non-adaptive pathways. To address this question, we use a Markov decision process to formulate the stochastic optimization problem. We quantify future learning about sea level rise uncertainty through sea level rise learning scenarios based on and validated against the latest scenarios of the Intergovernmental Panel on Climate Change. Our case study results show that the city of Lübeck is currently under-protected against storm surges and that immediate adaptation actions are advisable in the face of future sea level rise.

Research highlights sociodemographic disparities related to heat stress vulnerability, especially among older adults, women and individuals with low socioeconomic status, leading to higher morbidity and mortality rates. There is thus an urgent need for detailed, local information on demographic characteristics underlying vulnerability with refined spatial resolution. This study aims to address the research gaps by presenting a new population projection exercise at high-resolution based on the Bayesian modeling framework for the case study of Madrid, using demographic data under the scenarios compatible with the Shared Socioeconomic Pathways. We examine the spatial and temporal distribution of population subgroups at the intra-urban level within Madrid. Our findings reveal a concentration of vulnerable populations, as measured by their age, sex and educational attainment level in some of the city's most disadvantaged neighborhoods. These vulnerable clusters are projected to widen in the future unless a sustainable trajectory is realized, driving vulnerability dynamics toward a more uniform and resilient change.

We find a quadratic response of plant photosynthesis to aerosol loading due to trade-offs between diffuse fertilization effect and light limitations. The estimations show that China's air pollution suppresses terrestrial carbon uptake through aerosol-induced light limitations, leading to a 7.3% decrease in plant productivity in the 2010s.

Based on active layer thickness (ALT) monitoring data, meteorological data and normalized difference vegetation index (NDVI) data, we found that most ALT-monitored sites in the Northern Hemisphere show an increasing trend in NDVI and ALT. This suggests an overall increase in NDVI from 1980 to 2021 while permafrost degradation has been occurring. Permafrost degradation positively influences NDVI growth, with the intensity of the effects varying across land cover types and permafrost regions. Furthermore, based on Mann-Kendall trend test, we detected abrupt changes in NDVI and environmental factors, further confirming that there is a strong consistency between the abrupt changes of ALT and NDVI, and the consistency between the abrupt change events of ALT and NDVI is stronger than that of air temperature and precipitation.
