WASHINGTON, Mar 12 2013 (IPS) – Cyber threats appear to have largely replaced terrorism as posing the greatest risks to U.S. national security, which also confronts major longer-term challenges from the effects of natural resource shortages and climate change, according to the latest in a series of annual threat assessments by the U.S. intelligence community.
On climate change and natural resources, the report stressed that competition and scarcity “are growing security threats” and that “(e)xtreme weather events (floods, droughts, heat waves) will increasingly disrupt food and energy markets, exacerbating state weakness, forcing human migrations, and triggering riots, civil disobedience, and vandalism.” Disruptions in food supplies caused by, among other things, extreme weather conditions, competition for land between a number of actors, including wealthy foreign countries that are buying up land in poor countries, and population growth, are likely to lead to political violence and insurgencies. Much the same applies to reductions in freshwater supplies.
