Climate change will bring global tension, US intelligence report says

"Climate concerns cannot be separated with other security concerns, like China's competition. This country is facing a host of climate risks. These include rising sea levels that affect millions of people living in coastal cities and flooding that threatens its energy infrastructure. Desertification and migrating fish stock that could undermine its food security are just a few examples. If the country's national security strategy does not consider these factors, it will be unable to answer key questions about China.
