Risks associated with global warming of 1.5 to 4 °C above pre-industrial levels in human and natural systems in six countries Open
The Topical Collection “Accrual of Climate Change Risk in Six Vulnerable Countries” provides a harmonised assessment of risks to human and natural systems due to global warming of 1.5–4 °C in six countries (China, Brazil, Egypt, Ethiopia, …
Determinants of the distribution of utility-scale photovoltaic power facilities across the globe Open
Photovoltaic power (PV) is the fastest-growing source of renewable electricity. Making reliable scenarios of PV deployment requires information on what drives the spatial distribution of PV facilities. Here we empirically derive the determ…

Quantifying risks avoided by limiting global warming to 1.5 or 2 °C above pre-industrial levels Open
The Paris Agreement aims to constrain global warming to ‘well below 2 °C’ and to ‘pursue efforts’ to limit it to 1.5 °C above pre-industrial levels. We quantify global and regional risk-related metrics associated with these levels of warmi…
Exploration of the theoretical, financial, technical and sustainable hydropower generation potential in the Upper Indus basin Open
Hydropower investment decisions in the Upper Indus take a short-sighted approach based on energy generation potential at individual hydropower sites considering historical hydro-climatology. But hydropower will increasingly be affected in …
Climate change impacts on the energy system: a model comparison Open
Increasing renewable energy use is an essential strategy for mitigating climate change. Nevertheless, the sensitivity of renewable energy to climatic conditions means that the energy system’s vulnerability to climate change can also become…
Efficiency improvement and technology choice for energy and emission reductions of the residential sector Open
The residential sector currently accounts for one fifth of global energy use and corresponding greenhouse gas emissions, largely driven by increasing demand for space heating and cooling. Climate change mitigation action requires these to …
The 2021 SSP scenarios of the IMAGE 3.2 model Open
The SSP (Shared Socio-economic Pathways) scenarios are intensively used in climate and environmental research to explore uncertain future developments and possible response strategies. This paper briefly describes an update of the SSP scen…

Integrated assessment model diagnostics: key indicators and model evolution Open
Integrated assessment models (IAMs) form a prime tool in informing about climate mitigation strategies. Diagnostic indicators that allow comparison across these models can help describe and explain differences in model projections. This in…

Quanitification of sustainable hydropower potential in the Upper Indus basin Open
Considering the lack of a comprehensive assessement of hydropower potential in the Upper Indus basin, we developed and implemented a systematic framework to explore four different classes of hydropower potential. Our framework uses high-re…
Determinants of the global distribution of solar PV parks  Open
Suitability maps for solar photovoltaic (PV) parks are key in estimating potential supply of these resources. These maps are typically created based on expert judgement using variables such as resource availability (irradiation), topograph…
Decarbonising the critical sectors of aviation, shipping, road freight and industry to limit warming to 1.5–2°C Open
Limiting warming to well below 2°C requires rapid and complete decarbonisation of energy systems. We compare economy-wide modelling of 1.5°C and 2°C scenarios with sector-focused analyses of four critical sectors that are difficult to deca…

Afforestation for climate change mitigation: Potentials, risks and trade-offs, and the role of biophysical climate effects Open
Afforestation is considered a cost-effective and readily available climate change mitigation option. In recent studies afforestation is presented as a major solution to limit climate change. However, estimates of afforestation potential va…
Minimizing biodiversity trade-offs of future global hydropower reservoirs by strategic site selection Open
The Sustainable Development Goals (SDG) require increased hydropower electricity production to reach SDG 7. However, a balance between related positive synergies and negative trade-offs needs to be found. So far there has been a strong foc…
