As the Atlantic hurricane season kicks off this month, some coastal communities in the United States and small-island nations in the Caribbean are still recovering from last year’s record-breaking damage. At the same time, the heavy rains pounding the East Coast this week are part of a long-term trend towards more severe heavy rainfall events that have led to deadly floods and threaten critical U.S. military bases. Even on sunny days, cities such as Norfolk and Manila contend with high tide or “nuisance” flooding—a phenomenon that has increased as much as nine-fold since the 1960s, according to NOAA.

The new climate deal coming out of Paris commits governments to hold the rise in average global temperatures to “well below” two degrees Celsius compared to preindustrial levels. An important dimension of this agreement calls for subsequent work on limiting the increase to 1.5 degrees. This is an important win for islands and other low-lying countries, and for humanity.

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.

“Clean energy has gone from being the ‘right thing to do’ in combating climate change, to being the most cost-effective option for many energy-insecure countries,” said Carrie Thompson, deputy director of the U.S. Agency for International Development’s Regional Development Mission for Asia, during a day-long conference on renewable energy at the Wilson Center on October 27 (read part one of our coverage here).

The world has entered a new energy era. Last year, for the first time in four decades, the global economy grew without an increase in CO2 emissions, according to the Renewable Energy Policy Network for the 21^st Century.
