Climate change-induced sea level rise (SLR) is projected to be substantial, triggering human adaptation responses, including increasing protection and out-migration from coastlines. Yet, in macroeconomic assessments of SLR the latter option has been given little attention. We fill this gap by providing a global analysis of the macroeconomic effects of adaptation to SLR, including coastal […]

Relocating communities out of increasingly risk-prone areas is effective for adapting to climate change. Relocations are particularly relevant for small island regions, where sea-level-rise-induced retreat from the coast will be inevitable for some communities. However, relocations are contested because communities are generally reluctant to move, and decision-makers face high political risks. As a consequence, relocations […]

This study provides a literature-based comparative assessment of uncertainties and biases in global to world-regional scale assessments of current and future coastal flood risks, considering mean and extreme sea-level hazards, the propagation of these into the floodplain, people and coastal assets exposed, and their vulnerability. Globally, by far the largest bias is introduced by not […]

There is increasing concern among financial regulators that changes in the distribution and frequency of extreme weather events induced by climate change could pose a threat to global financial stability. We assess this risk, for the case of floods, by developing a simple model of the propagation of climate-induced shocks through financial networks. We show […]

Protecting densely populated coastal areas, such as river deltas or megacities, from sea-level rise with dikes and seawalls will likely limit land loss and migration of people away from the coasts. But these protections are overlooked in most migration estimates. A new study predicts coastal protection could limit migration to 17 to 72 million people […]

The European Green Deal – More Than Climate Neutrality The European Green Deal aims at climate neutrality for Europe by 2050, implying a signifi cant acceleration of emission reductions. To gain the necessary support, it needs to reduce regional and social inequalities in Europe. We present objectives in terms of jobs, growth and price stability […]

The release of new and updated sea‐level rise (SLR) information, such as from the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports, needs to be better anticipated in coastal risk and adaptation assessments. This requires risk and adaptation assessments to be regularly reviewed and updated as needed, reflecting the new information but retaining useful information […]

Global scale assessments of coastal flood damage and adaptation costs under 21st century sea-level rise are associated with a wide range of uncertainties, including those in future projections of socioeconomic development (shared socioeconomic pathways (SSP) scenarios), of greenhouse gas concentrations (RCP scenarios), and of sea-level rise at regional scale (RSLR), as well as structural uncertainties […]

Coastal populations are experiencing relative sea-level rise up to four times faster than the global average – according to new research from an international research team that includes Global Climate Forum. A new study published today in Nature Climate Change is the first to analyse global sea-level rise combined with measurements of sinking land. Climate-induced […]

The predominant responses to rising sea levels are in situ adaptations. However, increasing rates of sea-level rise will render ex situ adaptations—in the form of relocations—inevitable in some low-lying coastal zones. Particularly small island states like the Maldives face this significant adaptation challenge. Here, government action is necessary to move vulnerable communities out of flood-prone […]
