Ten new insights in climate science 2022

We summarize what we assess as the past year's most important findings within climate change research: limits to adaptation, vulnerability hotspots, new threats coming from the climate–health nexus, climate (im)mobility and security, sustainable practices for land use and finance, losses and damages, inclusive societal climate decisions and ways to overcome structural barriers to accelerate mitigation and limit global warming to below 2°C.

Research results of a new combined method in climate adaptation

Climate Change Adaptation in Africa, Asia, and Europe with the Citizen Science Climate Scan Platform Promoting Nature-Based Solutions

There is a clear demand for a collaborative knowledge-sharing by online climate adaptation platforms that contribute to (inter)national knowledge exchange and raising awareness about climate change. Climate adaptation platforms (CAPs) can contain decision-support tools to facilitate the process of decision-making, and may include capacity building, networking, dissemination to assist planning and implementation of proven adaptation concepts such as Nature-based solutions (NBS) to mitigate floodings, drought, and heat stress. From 2014 over 6000 global climate adaptation projects have been mapped on an open source platform ClimateScan using citizen science. This chapter describes the potential of this climate adaption platform by illustrated case studies with mapped climate adaptation measures in Africa, Asia, and Europe. The case studies illustrate engagement and tangible results related to online platforms such as: the period of relevance of ClimateScan, inclusiveness and engagement of users in different stages and continents. Workshops in Indonesia illustrate the need for validation of needs from potential users before implementing CAPs. Analyzing projects in Africa showcase best management practices in water conservation and water demand management that are of interest in many other regions in the world facing drought. In Europe detailed analysis of over 3000 climate adaptation measures in relation to neighborhood typologies is inspiring urban planners and stormwater managers to design, plan, and implement climate resilient measures with more confidence. These three global examples illustrate that mapping, promoting, and sharing knowledge about implemented proven concepts is raising awareness, contribute to community-building, and accelerate climate action around the world.

First City Climate Scan Rotterdam is promising

Research results of a new combined method in climate adaptation

Cities are becoming increasingly vulnerable for climate change and there is an urgent needto become more resilient. This research involves the development of the City climate scanRotterdam (September 2017) methodology to measure, map, scan and assess differentparameters that together give insight in the vulnerability of urban areas and neighborhoods.The research at recent City climate scan / Sketch your city in April 2018 used storytelling andsketching1 as main method to connect stakeholders, motivate action, evoke recognition in ajointly formulated goal, such as taking climate action. The city climate scan also involved thedevelopment of a set of measurement tools that can be applied in different urbanneighborhoods in a low-cost low-tech approach with teams of stakeholders andpractitioners. The city climate scan method was tested in different cities around the globe(Rotterdam, Manila and Cebu) in groups of young professionals and stakeholders in rapidurban appraisals.

Research results of a new governance method in climate adaptation

Cities are becoming increasingly vulnerable to climate change and there is an urgent need to become more resilient. This research involves the development of the City Climate Scan methodology to measure, map, scan and assess different parameters that provide insight into the vulnerability of urban areas and neighborhoods. The research involved the development of a set of measurement tools that can be applied in different urban neighborhoods in a low-cost low-tech approach with teams of stakeholders and practitioners. The City Climate Scan method was tested in different cities around the globe with groups of young professionals and stakeholders in rapid urban appraisals.For the Rotterdam City Climate Scan (September 2017), the following challenges were selected: risk of flooding, heat stress, water quality (micro-pollutants and plastic waste) and air quality. The Rotterdam climate scan is evaluated with their triple helix partners (public, private and academic partners). The conclusion is that the City Climate Scan approach helps policy makers and practitioners to gather valuable data for decision makers in a rapid appraisal at the neighborhood and city level. The results of the City Climate Scan methodprovides insights, creates awareness and brings together stakeholders. The most valuable deliverable is the concrete and tangible results. The participatory approach brings residents and practitioners together and provides insight into local problems, while at the same time the method facilitates the collection of valuable data about the robustness of neighborhoods. As a result of this positive evaluation, the City Climate Scan will be up scaled to a number of cities in Europe and Asia in the upcoming months.
