Health losses attributed to anthropogenic climate change
Over the last decade, attribution science has shown that climate change is responsible for substantial death, disability and illness. However, health impact attribution studies have focused disproportionately on populations in high-income countries, and have mostly quantified the health outcomes of heat and extreme weather. A clearer picture of the global burden of climate change could encourage policymakers to treat the climate crisis like a pub…

Addressing Food Insecurity Through Community Kitchens During the Covid-19 Pandemic
One of the most critical impacts of the COVID-19 pandemic was on food security. Food insecurity increased in many communities, with some showing signs of resilience through autonomously creating community kitchens that enhanced food security and built support networks. These initiatives filled gaps left by government programmes and provided a critical lifeline for vulnerable communities during the pandemic, fostering community solidarity. This pa…
Knowledge for change or more of the same? The role of policy knowledge systems in the Nationally Determined Contributions of Ghana, Kenya and South Africa
Attributing the driving mechanisms of the 2015–2017 drought in the Western Cape (South Africa) using self-organising maps
The Southwestern Cape (SWC) region in South Africa experienced a severe rainfall deficit between 2015–2017. The resulting drought caused the City of Cape Town to almost run out of water during the summer of 2017–2018. Using the self-organising maps approach, we identify and classify the synoptic circulation states over Southern Africa known to influence the local climate in the SWC into three groups (dry, intermediate, and wet circulation types) …
Operationalising climate-resilient development pathways in the Global South
National and sub-national actors are grappling with how to urgently move from climate change commitments to widespread actions that drastically reduce the risks posed by a changing climate and greenhouse gas emissions driving this change in tandem with addressing socio-economic inequalities. A pivotal challenge is how to cohere and sequence interventions in light of competing priorities, changing risk profiles and deep structural inequalities. Id…
Interrogating ‘effectiveness’ in climate change adaptation
The Paris Agreement articulates a global goal on adaptation, which aims to ensure an ‘adequate adaptation response’ to the ‘global temperature goal’, and requires countries to report progress through periodic global stocktakes. However, there remain conceptual and methodological challenges in defining an adaptation goal and mixed evidence on what effective adaptation looks like and how it can be enabled. In this review, we demonstrate how differe…
Managing city-scale slow-onset disasters
Disaster planning for slow-onset city-wide shocks will be become increasingly necessary, particularly as cities face increasingly severe climate hazards. This paper provides unique insight into the disaster planning and management that was undertaken by the City of Cape Town government in response to its most severe hydrological drought on record. It describes how risk was understood and why decisions were made on key elements of the plan, includ…
A systematic global stocktake of evidence on human adaptation to climate change
A framework for complex climate change risk assessment
Real-world experience underscores the complexity of interactions among multiple drivers of climate change risk and of how multiple risks compound or cascade. However, a holistic framework for assessing such complex climate change risks has not yet been achieved. Clarity is needed regarding the interactions that generate risk, including the role of adaptation and mitigation responses. In this perspective, we present a framework for three categorie…

Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town
Anthropogenic forcing of the climate is estimated to have increased the likelihood of the 2015-2017 Western Cape drought, also called 'Day Zero' drought, by a factor of three, with a projected additional threefold increase of risk in a world with 2 C warming. Here, we assess the potential for geoengineering using stratospheric aerosols injection (SAI) to offset the risk of 'Day Zero' level droughts in a high emission future climate using climate …
Understanding the current state of collaboration in the production and dissemination of adaptation knowledge in Namibia
Adaptation to climate change is challenging in terms of managing knowledge flow among diverse actors. This paper examines the roles of key actors in Namibia in the production and dissemination of climate adaptation knowledge. The intention was to identify opportunities for enhancing collaboration among actors to facilitate knowledge flow and uptake in adaptation action. The Omusati Region was used as a case study in understanding the chain of int…
Preparing interdisciplinary leadership for a sustainable future
Urgent sustainability challenges require effective leadership for inter- and trans-disciplinary (ITD) institutions. Based on the diverse experiences of 20 ITD institutional leaders and specific case studies, this article distills key lessons learned from multiple pathways to building successful programs. The lessons reflect both the successes and failures our group has experienced, to suggest how to cultivate appropriate and effective leadership,…

Assessing protected area effectiveness within the Caribbean under changing climate conditions
Anthropogenic influence on the drivers of the Western Cape drought 2015–2017
In the period 2015-2017, the Western Cape region has suffered from three consecutive years of below average rainfall-leading to a prolonged drought and acute water shortages, most prominently in the city of Cape Town. After testing that the precipitation deficit is the primary driver behind the reduced surface water availability, we undertake a multi-method attribution analysis for the meteorological drought, defined in terms of a deficit in the …
Spatial variability in sustainable development trajectories in South Africa
The Sustainable Development Goals (SDGs) represents the first globally agreed framework to address human development and environmental stewardship in an integrated way. One approach to summarising national SDG status is our "barometer for inclusive sustainable development in South Africa". The barometer downscales global social and planetary boundaries to provide status and trends for 20 critical indicators of environmental stress and social depr…
Climate change and loss, as if people mattered
The United Nations Framework Convention on Climate Change ( UNFCCC ) is seeking to prepare for losses arising from climate change. This is an emerging issue that challenges climate science and policy to engage more deeply with values, places, and people's experiences. We first provide insight into the UNFCCC framing of loss and damage and current approaches to valuation. We then draw on the growing literature on value‐ and place‐based approaches …

Climate change impacts and adaptation in South Africa
In this paper we review current approaches and recent advances in research on climate impacts and adaptation in South Africa. South Africa has a well‐developed earth system science research program that underpins the climate change scenarios developed for the southern African region. Established research on the biophysical impacts of climate change on key sectors (water, agriculture, and biodiversity) integrates the climate change scenarios but f…
Spatial coherence of meteorological droughts in the UK since 1914
We apply the drought severity index ( DSI ) on a multi‐temporal basis to a monthly precipitation dataset to study the spatial coherence of meteorological droughts in the UK since 1914. Analyses are undertaken for the wet ( O ctober– M arch) and dry ( A pril– S eptember) seasons and for moderate and extreme drought severities. We develop a drought covariance index that allows us to quantify the spatial coherence of droughts based on the fraction o…

The 1992 UN Framework Convention on Climate Change commits signatories to preventing ‘dangerous anthropogenic interference with the climate system’, leaving unspecified the level of global warming that is dangerous. In the late 1990s, a limit of 2 ° C global warming above preindustrial temperature was proposed as a ‘guard rail’ below which most of the dangerous climate impacts could be avoided. The 2009 Copenhagen Accord recognized the scientific…

African climate change
This paper reviews observed and possible future (2000-2100) continentwide changes in temperature and rainfall for Africa. For the historic period we draw upon a new observed global climate data set which allows us to explore aspects of regional climate change related to diurnal temperature range and rainfall variability. The latter includes an investigation of regions where seasonal rainfall is sensitive to El Nio climate variability. This review…
A high-resolution data set of surface climate over global land areas
We describe the construction of a 10' latitude/longitude data set of mean monthly surface climate over global land areas, excluding Antarctica. The climatology includes 8 climate elements -precipitation, wet-day frequency, temperature, diurnal temperature range, relative humidity, sunshine duration, ground frost frequency and windspeed -and was interpolated from a data set of station means for the period centred on 1961 to 1990. Precipitation was…

Global observed changes in daily climate extremes of temperature and precipitation
A suite of climate change indices derived from daily temperature and precipitation data, with a primary focus on extreme events, were computed and analyzed. By setting an exact formula for each index and using specially designed software, analyses done in different countries have been combined seamlessly. This has enabled the presentation of the most up‐to‐date and comprehensive global picture of trends in extreme temperature and precipitation in…
