Increasing evidence suggests that climate change impacts are already observed around the world. Global environmental assessments face challenges to appraise the growing literature. Here we use the language model BERT to identify and classify studies on observed climate impacts, producing a comprehensive machine-learning-assisted evidence map.
Costs and benefits of adaptation
In order to assess feasible adaptation options the analysis of costs and benefits is crucial. Adaptation costs mainly refer to making society more resilient to climate change and the benefits consist of avoided damage by adjusting to climate change.
Constraints and limits to adaptation are critical to understanding the extent to which human and natural systems can successfully adapt to climate change.
The impacts of climate change on the food system are a key concern for societies and policy makers globally. Assessments of the biophysical impacts of crop productivity show modest but uncertain impacts. But crop growth is not the only factor that matters for the food production. Climate impacts on the labour force through increased heat stress also need to be considered. Here, we provide projections for the integrated climate-induced impacts on crop yields and worker productivity on the agro-economy in a global multi-sector economic model.
This study provides projections of future governance in line with the Shared Socioeconomic Pathways. The study finds that under a ‘rocky road’ scenario, 30% of the global population would live in countries with weak governance in 2050, while under a ‘green road’ scenario, weak governance would be almost entirely overcome. On the basis of the governance pathways, the study also estimates the capacity of countries to adapt to climate change.
The first UNEPAdaptation Gap Report serves as a preliminary assessment of global adaptation gaps in finance, technology and knowledge, and lays out a framework for future work on better defining and bridging these gaps.
Africa is anticipated to be confronted with the severest adverse effects of human-induced climate change, compared to most other regions of the world, due to a combination of particularly severe projected impacts and relatively low adaptive capacity (e.g. IPCC AR4, World Bank 2013). The need for adaptation is expected to be high in Africa, especially in light of the existing deficit in adaptation to current climate variability and climate change. However, under any scenario of global mitigation and strong regional adaptation efforts, considerable adverse effects of climate change on Africa will remain, resulting in loss and damage.
The project aims to investigate how changes in land cover and land management can help to meet the mitigation and adaptation objectives of the Paris Agreement, as well as the Sustainable Development Goals. The project partners findings will be disseminated through a number of tools, events and products and by closely involving stakeholders and policy-makers, with the aim to support sustainable land use decision-making.
The EmBARK-project investigates time scales and possible trajectories of socio-economic transformation processes and analyse their relevance as potential barriers to adaptation to climate change. An improved understanding of the temporal dynamics of such barriers is key in developing a more realistic understanding of future climate impacts and for scientifically robust assessment of future climate related loss and damage.
The "Climate Action Tracker" is an independent science-based assessment, which tracks the emission commitments and actions of countries.
This project is an extension of the PAS-PNA project in Benin, Senegal and Burkina Faso. In each country, Climate Analytics, together with the national Green Climate Fund (GCF) Accredited Entity, is conducting the pre-feasibility or feasibility studies for selected adaptation projects, providing governments with an evidence-base to support the development of GCF concept notes and funding proposals.
