Climate change and risk

The effects of climate change are already happening and, even if action is taken to reduce global warming, they will continue to grow for decades. Their impact on security is increasingly being recognized in diverse policy communities, with the World Economic Forum naming in 2016 the 'failure to adapt and mitigate climate change' as 'the most impactful risk for the years to come.'

Some effects of climate change clearly pose immediate risk to human life, both from drought and flooding. Other effects appear more gradually, but already have a considerable impact on people's security, such as food and water insecurity, health, declining tourism industry and being forced to move as localities become uninhabitable. Some effects of climate change also have geopolitical implications as territorial boundaries change and resource scarcities affect the causes and dynamics of violent conflicts. SIPRI’s work on climate change and risk emerges from a comprehensive understanding of security encompassing both human and state security risks posed by climate change.
