Understanding the interplay between multiple climate change risks and socioeconomic development is increasingly required to inform effective actions manage these pursue sustainable development. We calculate a set of 14 impact indicators at different levels global mean temperature (GMT) covering water, energy land sectors from an ensemble climate, integrated assessment models. The analysis includes changes in drought intensity water stress index, cooling demand heat event exposure, habitat...
Abstract Achieving net-zero CO 2 emissions has become the explicitgoal of many climate-energy policies around world. Although studies have assessed pathways, common features and tradeoffs energy systems across global scenarios at point not yet been evaluated. Here, we examine 177 discuss their long-term technological regional characteristics in context current policies. We find that, on average, renewable sources account for 60% primary (compared to ∼14% today), with slightly less than half...
Abstract Seasonal mismatches between electricity supply and demand is increasing due to expanded use of wind, solar hydropower resources, which in turn raises the interest on low-cost seasonal energy storage options. pumped (SPHS) can provide long-term at a relatively co-benefits form freshwater capacity. We present first estimate global assessment SPHS potential, using novel plant-siting methodology based high-resolution topographical hydrological data. Here we show that costs vary from...
Abstract Droughts that exceed the magnitudes of historical variation ranges could occur increasingly frequently under future climate conditions. However, time emergence unprecedented drought conditions change has rarely been examined. Here, using multimodel hydrological simulations, we investigate changes in frequency (defined as abnormally low river discharge) high and greenhouse gas concentration scenarios existing water resource management measures estimate first regional centered on...
Abstract. While the Intergovernmental Panel on Climate Change (IPCC) physical science reports usually assess a handful of future scenarios, Working Group III contribution climate mitigation to IPCC's Sixth Assessment Report (AR6 WGIII) assesses hundreds thousands emissions scenarios. A key task in WGIII is global mean temperature outcomes these scenarios consistent manner, given challenge that from different integrated assessment models (IAMs) come with sectoral and gas-to-gas coverage...
Abstract The remaining carbon budget (RCB), the net amount of CO 2 humans can still emit without exceeding a chosen global warming limit, is often used to evaluate political action against goals Paris Agreement. RCB estimates for 1.5 °C are small, and minor changes in their calculation therefore result large relative adjustments. Here we recent assessments by IPCC present more data, refinements robustness checks that increase confidence them. We conclude 50% chance keeping around 250 GtCO as...
Abstract Scenarios have been an important integrating element in the Sixth Assessment Report (AR6) of Intergovernmental Panel on Climate Change (IPCC) understanding possible climate outcomes, impacts and risks, mitigation futures. Integration supports a consistent, coherent assessment, new insights opportunity to address policy-relevant questions that would not be otherwise, for example, which are unavoidable, reversible, what is consistent remaining carbon budget keep temperatures below...
Thermoelectric generation contributes to 80% of global electricity production. Cooling thermoelectric plants is often achieved by water abstractions from the natural environment. In England and Wales, sector responsible for approximately half all 40% non-tidal surface abstractions. We present a model that quantifies current use UK it test six decarbonisation pathways 2050. The consist variety technologies, with associated cooling methods, factors sources. find up 2030, across fairly...
With growing health risks from rising temperatures in the Global South, lack of essential indoor cooling is increasingly seen as a dimension energy poverty and human well-being. Air conditioning (AC) expected to increase significantly with incomes, but it likely that many who need AC will not have it. We estimate current location extent populations potentially exposed heat stress South. apply variable degree days (VDD) method on global grid demand required meet these needs, accounting for...
Abstract Spatially explicit data on electricity access and use are essential for effective policy-making infrastructure planning in low-income, data-scarce regions. We present validate a 1- km resolution dataset covering sub-Saharan Africa built gridded nighttime light, population, land cover data. Using light radiance probability distributions, we define consumption tiers urban rural areas estimate the by-tier split of consumers living electrified areas. The approach provides new insight...
Abstract Buildings account for 36% of global final energy demand and are key to mitigating climate change. Assessing the evolution building stock its is critical support mitigation strategies. However, most studies lack granularity overlook heterogeneity in sector, limiting evaluation transformation scenarios. We develop residential scenarios along shared socio-economic pathways (SSPs) 1–3 assess stock, demand, CO 2 emissions space heating cooling with MESSAGEix-Buildings, a modelling...
The risks of cooling water shortages to thermo-electric power plants are increasingly studied as an important climate risk the energy sector. Whilst electricity transmission networks reduce during disruptions, more costly must provide alternative supplies. Here, we investigate price impacts on Britain’s supplies using a probabilistic spatial model regional climate, hydrological droughts and shortages, coupled with economic supply, demand prices. We find that extreme days (p99), almost 50%...
Energy systems support technical solutions fulfilling the United Nations' Sustainable Development Goal for clean water and sanitation (SDG6), with implications future energy demands greenhouse gas emissions. The sector is also a large consumer of water, making efficiency targets ingrained in SDG6 important constraints long-term planning. Here, we apply global integrated assessment model to quantify cost characteristics infrastructure pathways balancing access, scarcity, treatment...
Abstract This study presents the development of a new bottom‐up large‐scale hydroeconomic model, Extended Continental‐scale Hydroeconomic Optimization (ECHO), that works at subbasin scale over continent. The strength ECHO stems from integration detailed representation local hydrological and technological constraints with regional global policies, while accounting for feedbacks between water, energy, agricultural sectors. In this study, has been applied Africa as case aim demonstrating...
The Indus River Basin covers an area of around 1 million square kilometers and connects four countries: Afghanistan, China, India, Pakistan. More than 300 people depend to some extent on the basin's water, yet a growing population, increasing food energy demands, climate change, shifting monsoon patterns are exerting pressure. Under these pressures, "business as usual" (BAU) approach is no longer sustainable, decision makers wider stakeholders calling for more integrated inclusive...
Abstract This paper presents one of the first quantitative scenario assessments for future water supply and demand in Asia to 2050. The assessment, developed by Water Futures Solutions ( WFaS ) initiative, uses latest set global climate change socioeconomic scenarios state‐of‐the‐art hydrological models. In Asia, irrigation, industry, households is projected increase substantially coming decades (30–40% 2050 compared 2010). These changes are expected exacerbate stress, especially current...
Ending energy poverty is a necessary condition for achieving the Sustainable Development Goals (SDGs). Boosting electricity access levels is, however, insufficient if consumption and reliability indicators stagnate. Previous research has shown that satellite-derived data can complement field surveys in tracking but with little consideration multi-dimensionality of role demographic dynamics. Here, we process 6 years high-resolution population, nighttime light, settlement sub-Saharan Africa to...
