"A panel of US national security, military and intelligence experts released a report on 24 February that examines the potential security implications of two future warming scenarios. It concludes that: Even at scenarios of low warming [1-2°C], each region of the world will face severe risks to national and global security in the next three decades. Higher levels of warming will pose catastrophic, and likely irreversible, global security risks over the course of the 21st century. In terms of global food and water security, it suggests that: …increasing global temperatures, melting glaciers, and prolonged drought conditions will put new pressure on freshwater sources, dwindling supply at a moment of increasing human demand. These stresses will be acutely felt in arid regions with low water quantity and large populations, where water use is already heavily regulated to prevent competition… Diminished water resources for irrigation, higher temperatures, and decreased soil fertility already impair crop yields, particularly in the global south. For coastal and island communities dependent on local aquaculture for their diets, rising ocean temperatures, migrating and diminishing fish stocks, and dying coral reefs put intense strain on these important natural sources of food and economic activity. Such agricultural stressors have been linked not only to nutritional deficiencies and food insecurity among households, but an increase of local social insecurity and political tension where development is low. The relationship between food insecurity and increase instances of riots or violence depends on how governments respond to the situation, and the history of inequality preceding the food shortage..."
