Common Climate Impact Assessments Underestimate Future Vulnerability

This article originally appeared on the Peace Research Institute – Oslo.

Climate-related disasters are a major source of human and material losses. Poverty and low level of economic development are important determinants of environmental vulnerability. Achieving stable and sustainable development thus represents an important strategy to reduce adverse impacts of climate change. However, present efforts to evaluate possible consequences of climate change in the future suffer from too optimistic assumptions about economic growth in poor countries, as we document in a new article just published in the journal Global Environmental Politics.

Minimizing loss and damage from climate change is a major societal challenge for developing and developed countries alike. In order to understand how climate change may affect vulnerable societies in the future, the climate change research community has developed five complementary scenarios of future development, the so-called Shared Socioeconomic Pathways (SSPs).

The five SSPs are not competing for accuracy but rather designed to constitute stylistic representations of alternative development pathways, intended to jointly capture the plausible ‘probability space’ of future changes in countries’ socioeconomic and demographic characteristics (Table 1).
