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.

These are among the findings of a new Pew Research Center survey, conducted in 40 countries among 45,435 respondents from March 25 to May 27, 2015. The report focuses on those who say they are “very concerned” about each issue.1

Anxiety about Climate Change High in Latin America, Africa

Across the nations surveyed, the level of concern about different international issues varies considerably by region and country, and in some places multiple issues vie for the top spot.


Sub-Saharan Africans also voice substantial concerns about climate change. A median of 59% say they are very concerned, including about half or more in all countries surveyed. Climate change is particularly worrying in Burkina Faso (79%), Uganda (74%) and Ghana (71%), while South Africans (47%) and Tanzanians (49%) are the least concerned.

Both regions are especially vulnerable to the effects of climate change, as is Asia, where a median of 41% voice great concern about the issue. Indians (73%) and Filipinos (72%) are particularly worried, but climate change captures the top spot in half of the Asian countries surveyed.

Top Threats by Region

Concern about climate change is relatively low in Europe. While a median of 42% report being very concerned, global climate change is not one of the top two threats in any European country surveyed. Anxiety about this issue is highest in Spain (59%), but just 14% in Poland say the same. In a number of European nations, concern about climate change is more pronounced for those on the left of the political spectrum. Ideological differences are particularly large in the United Kingdom, where about half of those on the left (49%) express serious concerns, compared with 30% of those on the right. Those to the left of the political center are also considerably more concerned about global climate change in Italy, France and Spain.

Global climate change ranks substantially lower as a comparative global threat for Americans, with 42% saying they are very concerned about the issue. The only global issue that is even less worrying to Americans: territorial disputes between China and its neighbors (30%). Much like in Europe, perceptions in the U.S. about the threat of climate change depend on ideology. About six-in-ten Democrats (62%) are very concerned about climate change, while just 20% of Republicans say the same.

Fear of ISIS in Europe, Middle East and U.S.

As ISIS continues to control territory in Iraq and Syria, concern in neighboring countries is high. More than eight-in-ten in Lebanese (84%) are very concerned about ISIS. Fear is especially high among Muslims in Lebanon, Syria’s western neighbor: 90% of Sunnis and 87% of Shia say they are very concerned, compared with 76% of Christians. More than half in Jordan (62%) and the Palestinian territories (54%) also express substantial worries about ISIS. Compared with other international issues, concern about ISIS also ranks highly in Israel and Turkey, which has seen a flood of refugees across its southern border as violence escalates.

A majority of Americans (68%) and Canadians (58%) are also very concerned about the looming threat of the Islamic State. In both countries, anxiety about ISIS is the top concern of the issues included in the survey. Concern is similarly high in a number of Asian nations, including South Korea (75%), Japan (72%), Australia (69%) and Indonesia (65%). Publics in all four countries cite ISIS as their top concern. Relatively few in Africa and Latin America voice serious concern about the threat of ISIS. Only in Tanzania do roughly half (51%) report substantial concerns, the highest of any country in either region.

Global Economy a Common Secondary Concern

Economic instability is among the top threats in Latin America, where a median of 54% express serious concerns. Six-in-ten in Brazil and Venezuela say they are very concerned about economic issues, the highest in Latin America. Both nations have seen little to no growth in the past year, and their economic woes are expected to deepen in 2015. Economic worries are similarly troubling for countries in Africa. Ghanaians (67%), Ugandans (62%) and Senegalese (59%) are most concerned about the economy, but economic instability is considered one of the top two concerns in every country surveyed in Africa.

Russia and Ukraine, which are facing contracting economies in 2015, consider economic instability a major threat. In Russia, 43% say they are very concerned about the economy, the highest-ranking concern of any issue tested there. About a third of Ukrainians (35%) agree; economic worries are second only to their concerns about tensions with Russia.

The economy is somewhat less concerning in Europe, Asia and the Middle East. Still, a third or more in each region say they are very concerned about global economic instability, and the issue still ranks as the second-highest threat in seven countries, including some of the world’s largest economies – China, France, India and Italy all rate economic issues as one of their top two concerns.

Fewer Are Concerned about Iran and Cyberattacks

Americans also see Iran’s nuclear program as a major issue. Roughly six-in-ten (62%) say they are very concerned, making Iran the second-highest-ranked threat of those included in the poll. While a median of 42% of Europeans express strong concern about Iran, only in the UK is it considered one of the top two dangers. Relatively few in Latin America, Africa, Asia and the Middle East say they are very concerned about Iran’s nuclear program.

Territorial Tensions Remain within Regions

Similarly, while there is little concern worldwide about territorial disputes between China and its neighbors, it is one of the top two concerns in a number of Asian nations, including Vietnam (60%) and the Philippines (56%). Both countries challenge China’s claim over islands in the South China Sea, where the Chinese government has recently constructed artificial islands.
