Abstract

Climate change is a substantial security concern not only because direct flooding and natural disasters can damage infrastructure, disrupt the delivery of imported commodities, and destroy crops, but also because it can have severe impacts on food security and nutrition, health, and environmental refugees, which can all lower the income base of Asian countries and add to government debt, further complicating attempts at sound policymaking. Under a business as usual scenario, the IPCC forecasts that emissions of all greenhouse gases will rise from 52.5 billion tons today to 140 billion tons by 2100 – almost a threefold increase, and also a trend discussed in other chapters in this book. The atmospheric concentration of carbon dioxide reached 396 parts per million (ppm) in 2012 and 407 ppm when all greenhouse gases are accounted for, and will rise to 1,410 ppm for all gases by 2100 under business as usual. Depending on assumptions and particular models, such emissions and concentrations could result in a temperature change of 4.81° Celsius by 2100.
