It is anticipated that, by 2020, from 500 to 750 million people will be affected by water stress caused by climate change around the world. Sea level will rise 2% in the year 2020, 4% by 2050 and 17.5% by 2100. It will affect agriculture, hamper food security, create health hazard,
abroad. For example, the impacts of climate change on key economic sectors, such as agriculture and water, can have profound effects on food security, posing threats to overall stability. The implications of climate change on national security are not all beyond U.S. borders – they pose risks here at home.

stress both people and ecosystems and decrease food and water security. Coasts Coastal lifelines, such as water supply infrastructure and evacuation routes, are increasingly vulnerable to higher sea levels and storm surges, inland flooding, and other climate-related changes. Oceans
agriculture and it is the short-term solution to climate change we need to implement today. We don’t have to wait for technological wizardry: regenerative organic agriculture can substantially mitigate climate change now. On-farm soil carbon sequestration can potentially sequester all of our current annual global
1. Introduction summary • Climate change will act as a hunger risk multiplier exacerbating current vulnerabilities, with one study projecting up to 20% more people at risk of hunger. • Climate change could affect all dimensions of food security in complex ways. Almost one billion people experienced hunger in 2010 (FAO/WFP, 2010): The most vulnerable people cannot access
