Climate change has been a key issue at the United Nations General Assembly this week. Meetings at the U.N. about the topic have been taking place during a season of calamitous weather events, including a series of devastating hurricanes.

While he believes that world leaders cannot ignore climate change, Bjorn Lomborg, president of the Copenhagen Consensus Center, says he is concerned that precious resources are too often squandered on ineffective solutions, and that aid money could be spent on better interventions that do the most social good.

Lomborg, the author of several books, including “The Skeptical Environmentalist,” discusses his ideas about the best way to prioritize spending on development aid.
