What are climate wars?

German sociologist Harald Welzer, who popularized the term “climate wars,” argues that a scarcity of resources — arable soil, food and water — is one of the powerful new forces shaping the 21st century. This has been intensified by the rise in global temperatures and ever more extreme weather.

What are two different mechanisms by which changes in climate might affect conflict?

The first one views climate as affecting the likelihood of conflict via direct physiological and/or psychological factors and resource scarcity. The second postulates that climate indirectly leads to conflict by reducing economic output and agricultural incomes, raising food prices, and increasing migration flows.

How does climate change affect the Navy?

Second, climate change may impair the capacity of the navy to deliver its services. As sea levels rise and weather patterns become more severe, the risk of damage to the domestic and global network of bases and ports on which it depends to maintain fleet readiness will also increase.
