11. “The impacts of climate change are expected to act as a ‘threat multiplier’ in many of the world’s most unstable regions, exacerbating droughts and other natural disasters as well as leading to food, water and other resource shortages that may spur mass migrations.”

Regarding food and water supplies, global crop production has soared as the Earth gradually warms. Atmospheric carbon dioxide is essential to plant life, and more it added to the atmosphere enhances plant growth and crop production. Plant growth and crop production also benefit from longer growing seasons and fewer frost events. Global crops set new production records virtually every year as our planet modestly warms.

The same holds true as per objective data for water supplies. As our planet warms, there is a gradual increase in global precipitation and soil moisture. Warmer temperatures evaporate more water from the oceans, which in turn stimulates more frequent precipitation over continental landmasses. This results in enhanced precipitation, which means an improvement in soil moisture at almost all sites in the Global Soil Moisture Data Bank.

If crop shortages, declining precipitation and declining soil moisture cause national security threats, then global warming benefits rather than jeopardizes national security.
