The 3rd version of the Climate Vulnerability Monitor: a free online tool providing globally comparable biophysical, macroeconomic and health climate impact information at the national level

The 3^rd version of the Climate Vulnerability Monitor (CVM3) is an independent global assessment of the impacts of climate change in the 21st century developed by a scientific consortium for the Climate Vulnerability Forum. It presents specific estimated climate change–attributable impact data that is internationally comparable in 32 biophysical, human health and economic indicators for most countries and all world regions. Based on the latest scenarios developed for the IPCC’s Sixth Assessment Report, the CVM3 assesses impacts for three scenarios (1.5°C scenario, a below 2°C scenario and a “no climate action” scenario) and three time slices (near-term (2030– mid-point year for 2021–2040), medium (2050) and end of the century (2090)).

The free online tool “CVM Data Explorer” draws on information, data and results of the different work packages made available by the partners through three respective application programming interfaces (APIs). While the health data explorer shows potential changes in climate-related health risks, the economics data explorer illustrates the extent to which climate change is projected to alter macroeconomic indicators. The biophysical explorer presents estimate changes in indicators like near-surface air temperature and precipitation, offers an overview of present attributable impacts as well as covering current and future vulnerability of over 180 countries. based on the given emission scenarios. The tool displays these results of current and projected impacts with maps for the different pathways and timeframes and the underlying data is freely available for download.

A multimedia part (“scrolly-telling”) of the tool takes a narrative-explorative approach to the results using different types of media such as video interviews, animations and interactive elements with local experts. These impact stories for five chosen countries (Bangladesh, Ghana, Kenya, Philippines, St. Lucia) aim to bring global databases together with regional to local impact and vulnerability information and showcase the CVM3 results in a narrative, concrete and exemplary manner.
