The failure to protect the people most vulnerable to climate change is especially alarming given the steady increase in the number of climate and weather-related disasters. According to the World Disasters Report, the average number of climate and weather-related disasters per decade has increased n...early 35 per cent since the 1990s.
Over the past decade, 83 per cent of all disasters were caused by extreme weather and climate-related events such as floods, storms, and heatwaves. Together, these disasters killed more than 410,000 people and affected a staggering 1.7 billion people.

Changes in climate, in conjunction with other drivers of mobility, shape human migration. While there is an increasing focus on the adaptive potential of migration, the health impacts of climate-related migration, including planned relocation and forced displacement, have not been thoroughly examine...d. The Intergovernmental Panel on Climate Change stated that migration is currently, and will increasingly be, influenced by environmental degradation and climate change, and that it needs to be addressed in a focused and coordinated manner

Background report
What at first glance appears to be simple causality – climate change leading to more and more migration – has triggered intense academic debate over the past ten years because the circumstances are complex. There is need for a thorough analysis in the ground between denying the problem and asser...ting immediate causality. In international relations, migration induced by climate change and environmental degradation is increasingly recognized as a problem, whether in the framework of international climate policy, international migration policy, development cooperation, or international crisis management. But considering the dimension of these major challenges, only small steps have been taken so far. The scope of the problem continues to be underestimated. Climate change is jeopardizing the livelihoods of more and more people. It is a risk multiplier. Although understanding of the connection between climate change and migration has increased, many questions have yet to be answered. We need more knowledge to better support the people affected.

Der Klimawandel verschärft die Treiber für Migration und Flucht
Zu den ohnehin bestehenden Gründen, die Menschen zum Verlassen ihrer Heimat zwingen, kommt der Klimawandel verschärfend hinzu. Schätzungen zur Rolle des Klimawandels sind wegen der Komplexität des Zusammenspiels verschiedener Mig...rations- oder Fluchtursachen äußerst schwierig. Die Vorhersagen über das mögliche Ausmaß von Migration infolge des Klimawandels gehen daher weit auseinander – bis zum Jahr 2050 könnten zwischen 25 und 700 Millionen Menschen davon betroffen sein (micle 2012).
