Tree phenology has been recognized as an important indicator of climate change, and a wide range of budburst models have been developed. The models differ in temperature sensitivity, and the choice of model can therefore influence the result of climate impact assessments. In this study we compared the ability of 15 models to simulate budburst of the main forest tree species in Sweden. Records on t
Aerosol-cloud interactions (ACI) constitute the single largest uncertainty in anthropogenic radiative forcing. To reduce the uncertainties and gain more confidence in the simulation of ACI, models need to be evaluated against observations, in particular against measurements of cloud condensation nuclei (CCN). Here we present a data set - ready to be used for model validation - of long-term observa
The effect of external forcings on atmospheric circulation is debated. Due to the short observational period, the analysis of the role of external forcings is hampered, making it difficult to assess the sensitivity of atmospheric circulation to external forcings, as well as persistence of the effects. In observations, the average response to tropical volcanic eruptions is a positive North Atlantic
With the adoption of the Sustainable Development Goals (SDGs), debates on governance through goal-setting and performance review have gained momentum. In this article, we explore how the politics of performance review played out in public sustainable development reporting at the global-national nexus.

Development assistance for health (DAH) remains a significant and important source of health financing in many low and lower middle-income countries. However, this assistance has not been fully effective. This study explores the effect of currency exchange rate fluctuations on volatility of DAH in Zambia using a mixed methods approach. Data covering the period 1997-2008 were collected from various
Policy brief, Marts 2024: Biokuls rolle i dansk klimapolitik Policy brief MARTS 2024 Biokuls rolle i dansk klimapolitik Biokul er i de senere år kommet på den danske klimadagsorden, som et virkemiddel til at adressere landbrugets drivhusgasudledninger. Der er dog stadig en række usikkerheder forbundne med biokul som klimavirkemiddel, der medfører at biokul risikerer at stå i vejen for udledningsre

Aerosols from volcanic eruptions impact our climate by influencing the Earth's radiative balance. The degree of their climate impact is determined by the location and injection altitude of the volcanic SO2. To investigate the importance of utilizing correct injection altitudes, we ran climate simulations of the June 2009 Sarychev eruptions with three SO2 datasets in the Community Earth System Mode
As growing populations concentrate in urban areas, it has become apparent that many global problems are a cumulative reflection of unsustainable practices at the local level. Correspondingly, there has been an increasing need to monitor and manage sustainable community growth, which includes a balance of environmental, economic, health, and social measures. Throughout the last decade, the communi
The aim of this paper is to study the extent to which non-Annex I countries are implementing or exploring select actions that support both climate change mitigation and sustainable development objectives in the energy sector. The research is based on a survey of the national communications of 100 non-Annex I Parties to the UNFCCC. Although national communications are intended to provide informatio
Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produc
Aim: How the ability of plants to move towards newly favourable habitats (dispersal limitation) impacts the change of biome distribution and transition under fast climate warming is still debated. Analysing vegetation change in the past may help to clarify the relative importance of underlying ecological processes such as climate, biotic interactions, and dispersal. In this study, we investigated
While climate models broadly agree on the changes expected to occur over the Arctic with global warming on a pan-Arctic scale (i.e. polar amplification, sea ice loss, and increased precipitation), the magnitude and patterns of these changes at regional and local scales remain uncertain. This limits the usability of climate model projections for risk assessments and their impact on human activities
Northern ecosystems, encompassing boreal forests, tundra, and permafrost areas, are increasingly affected by the amplified impacts of climate change. These ecosystems play a crucial role in determining the global carbon budget. To improve our understanding of carbon uptake in these regions, we evaluate the effectiveness of employing the physically-based Plant Phenology Index (PPI) to estimate gros
This chapter reflects on the need for a decolonial turn in Sweden’s foreign policy. The growing ecological emergencies that we are faced with call on us to recognise and address quite profound global inequities, many of which are rooted in histories of European colonialism. In a sprawling conversation about the coloniality of the global economy and Sweden’s role in it, the chapter addresses such t
Bark beetle infestations pose a significant threat to forest ecosystems, necessitating timely intervention for effective management and conservation. This study focuses on an 8,100 km2 area in southern Sweden, heavily impacted by a bark beetle outbreak triggered by a severe drought in 2018. Using spectral indices derived from Sentinel-2 data, it explores the potential of a window-based approach fo
Rapid urbanization in Guangdong Province has severely impacted river systems due to limited understanding of the sustainability of river connectivity and functions. This study applies the Minimum Cumulative Resistance Model (MCRM) to quantify expansion costs of natural and social processes, with their difference defined as the River Ecological Sensitivity (RES) index. Higher RES values indicate th
Dissolved Organic Carbon (DOC) is a key component of the inland water carbon cycle, playing a critical role in water quality, aquatic ecosystem dynamics, and carbon flux assessments. In this study, we combine Sentinel-2 Multi-Spectral Instrument (MSI) data with in-situ water quality, meteorological, and temporal variables to predict DOC concentrations in Lake Erken, Sweden. Three Machine Learning
Monitoring atmospheric CO2 concentration changes across China is crucial for reducing carbon emissions and tackling global warming. Due to monitoring gap in satellite observations, this paper uses the Extremely Randomized Trees (ERT) model alongside OCO-2 satellite data and predictor variables to develop a 0.1° high-resolution monthly dataset of column-averaged dry air CO2 mole fraction (XCO2) in
The Siljan-Orsasjön Basin in south-central Sweden hosts two prominent lakes. A 100 m deep channel extends approximately 52 km across the basin but does not form a continuous connection between the lakes today. Geophysical mapping, including multibeam bathymetry and sub-bottom profiling, revealed several landslide areas associated with the steep slopes of this channel and redistributed mass-wasted
