As climate change and policy responses grow more intense, prominent, and high-stakes, opportunities will grow for state and non-state actors to spread mis- and disinformation. These mis- and disinformation challenges go beyond climate denialism, and are present across the breadth of climate security risks. These risks comprise the physical impacts of climate disasters, cascading socio political impacts of climate change, and backlash or unintended consequences from climate policies themselves.

Livelihoods are central to the relationship between climate change and conflict. Changes in temperature and precipitation patterns negatively affect household income sources and food supply. The lack of alternative livelihood options, coupled with political, social and economic strife, may lead people to resort to violence to safeguard their means of survival.

The humanitarian–development–peace (HDP) nexus emphasizes the need to address crises through integrated approaches, aligning humanitarian, development and peacebuilding efforts.

Lessons from Yemen, Ukraine, and Libya

The world's water is in trouble. Freshwater pollution, coupled with climate change, population growth, and increasing demand, threatens water quality and availability. The strain is clear already, as 26% of the world’s population lacks access to safe drinking water, and a whopping 46% lack access to basic sanitation. In countries experiencing conflict, these percentages soar. In 2015, 38% of people living in conflict-affected states lacked basic drinking water.

Communities need to adapt to the havoc wrought by this weather phenomenon.

Some scientists suspect that atmospheric rivers, plumes of water vapor that transport water from the poles and dump heavy rain or snow when they hit land, caused the 'Great Flood' in 1862. These rivers in the sky have become increasingly powerful in the decades since, pummeling California and the western United States the past few winters. They will likely grow even more severe in a warming world. Western states need to prepare accordingly.

What effect will climate change have on military power, capabilities, effectiveness, and force employment? Despite the growing attention to climate change in the field of international relations scholars have paid little attention to how climate change directly affects military power and military operations.
