The year is 2022. Strong El Niño and La Niña events in successive years have drastically reduced wheat yields in India and Australia and increased the range of certain pests and plant pathogens in the Western Hemisphere. Moreover, a drought across North America has reduced corn and soybean yields significantly. Global commodity prices are up 262 percent over long-term averages. These price increases are compounding other social and economic challenges, contributing to social unrest in several food-importing nations.

Climate change is the world’s greatest environmental threat. It is also increasingly understood as a threat to domestic and international peace and security – recognized by the Department of Defense as a “threat multiplier,” by Secretary of State John Kerry as “perhaps the world’s most fearsome weapon of mass destruction,” and by President Obama, in an address to graduates of the United States Military Academy, as “a creeping national security crisis.” The Supreme Court’s temporary blocking of the Clean Power Plan highlights the Federal-State divide over how to address climate change, but because of its national security dimension, climate change also raises unique separation of powers issues between the president and Congress with regard to how the military can respond.

In November 2015, experts from a variety of fields gathered at the Peace Palace in The Hague for the Planetary Security Conference, one of the first large-scale conferences on environmental security and what is hoped to be the start of an annual series. The conference report gives a sense of the diverse discussions held in the Netherlands.

Despite evidence that natural resources play a major role in many conflicts – 40 percent of all civil wars since the end of the Cold War, according to an estimate by the UN Environment Program – a study conducted by Arthur G. Blundell and Emily E. Harwell for the NGO Forest Trends reveals that most ceasefire and peace agreements do not address natural resources.

Security, terrorism, conflict, and peace: you won’t find any of these words in the landmark agreement released on December 12 at the 2015 Paris Climate Conference (COP-21). It’s never been front-and-center on the agenda at previous Conference of Parties, from Copenhagen to Cancun. But in Paris, a city reeling from terrorist attacks, the specter of climate-related conflict haunted delegates and the potential of a climate-resilient peace inspired grassroots protests.

The agreement coming out of the COP-21 negotiations gave breakthrough recognition to the concept of “loss and damage,” sorting through thorny discussions and politically charged negotiating positions. These positions revolved around liability and compensation, which developing countries called for but developed countries were unwilling to have included in the agreement.

One of Prime Minister Narendra Modi’s first priorities after winning an overwhelming victory last year on a platform of development and growth is to fast-track a decades-old plan to link India’s rivers.

Climate change is a very real threat. It will have major implications for every country and region in the world, but South Asia is particularly vulnerable. To appropriately address the challenges there, the world will have to confront four misconceptions about climate change in South Asia. With world leaders convening in Paris to hash out a new agreement on climate change, now is the right time to do it.
