In advance of the United Nations Climate Change Conference in Paris this December, many publics around the world name global climate change as a top threat, according to a new Pew Research Center survey measuring perceptions of international challenges. This is particularly true in Latin America and Africa, where majorities in most countries say they are very concerned about this issue. But as the Islamic militant group ISIS maintains its hold in Iraq and Syria and intensifies its grisly public executions, Europeans and Middle Easterners most frequently cite ISIS as their main concern among international issues.
Global economic instability also figures prominently as the top concern in a number of countries, and it is the second biggest concern in half of the countries surveyed. In contrast, concerns about Iran’s nuclear program as well as cyberattacks on governments, banks or corporations are limited to a few nations. Israelis and Americans are among the most concerned about Iran’s nuclear program, while South Koreans and Americans have the greatest concern about cyberattacks relative to other publics. And apprehension about tensions between Russia and its neighbors, or territorial disputes between China and surrounding countries, largely remain regional concerns.
