Losses and Damages from Climate Change

Climate Tipping Points: Insights for Effective Policy Action
This report reviews evidence that overshooting 1.5°C may push the earth over several tipping points, leading to irreversible and severe changes in the climate system. If triggered, tipping point impacts will rapidly cascade through socio-economic and ecological systems, leading to severe effects on human and natural systems and imposing important challenges for human adaptation. Of particular concern are the likely collapse of the West Antarctic and Greenland ice sheets and the abrupt melting of permafrost grounds in the Arctic, which would result in additional sea-level rise and greenhouse gas releases, leading to more warming. Based on the most recent science and consultations with renowned experts, Climate Tipping Points: Insights for Effective Policy Action argues that it is no longer appropriate to consider the risk of crossing tipping points as low-probability. Overshooting 1.5°C may likely lead to irreversible and severe impacts, which must be avoided, heightening the urgency to drastically reduce emissions within this decade. The report calls for a shift in how tipping points are treated in climate policy today and provides recommendations on how climate risk management strategies can better reflect the risks of tipping points in the areas of mitigation, adaptation and technological innovation.

Building Financial Resilience to Climate Impacts: A Framework for Governments to Manage the Risks of Losses and Damages
Governments are facing significant climate-related risks from the expected increase in frequency and intensity of cyclones, floods, fires, and other climate-related extreme events. The report Building Financial Resilience to Climate Impacts: A Framework for Governments to Manage the Risks of Losses and Damages provides a strategic framework to help governments, particularly those in emerging market and developing economies, strengthen their capacity to manage the financial implications of climate-related risks. The goal of the framework is to support sound public financial management strategies that take into account budgetary and financing constraints, and to foster broader actions at the national and international levels. The report examines the role of governments in identifying and assessing climate-related physical risks and their impacts on public finances, and reporting climate-related fiscal risks to promote transparency in public financial management. It discusses how to mitigate those risks through protecting households and businesses, and developing integrated multipronged financial strategies to fund government expenditure needs. Finally, it calls for promoting integrated strategies to strengthen financial resilience at the country and regional levels, and for mobilising development co-operation to strengthen global climate financial resilience.

Managing Climate Risks, Facing up to Losses and Damages
This report addresses the urgent issue of climate-related losses and damages. Climate change is driving fundamental changes to the planet with adverse impacts on human livelihoods and well-being, putting development gains at risk. The scale and extent of future risks for a given location is, however, subject to uncertainties in predicting complex climate dynamics as well as the impact of individual and societal decisions that determine future greenhouse gas emissions as well as patterns of socio-economic development and inequality.

The report approaches climate-related losses and damages from a risk management perspective. It explores how climate change will play out in different geographies, over time, focusing on the three types of hazards: slow-onset changes such as sea-level rise; extreme events including heatwaves, extreme rainfall and drought; and the potential for large-scale non-linear changes within the climate system itself. The report explores approaches to reduce and manage risks with a focus on policy action, finance and the role of technology in supporting effective risk governance processes. Drawing on experiences from around the world, least developed countries and small island developing states in particular, the report highlights a number of good practices and points to ways forward.

A High-Level Advisory Group provided input and feedback on the development of the project. The group was composed of representatives from countries, development finance institutions, academic and other national and international actors. It was co-chaired by Masamichi Kono, OECD Deputy Secretary-General and Maria Flachsbarth, Parliamentary State Secretary, German Federal Ministry for Economic Cooperation and Development (BMZ).
