Climate change is the top security concern in a poll conducted by the Washington-based Pew Research Center, followed by Islamist terrorism and cyberattacks while respondents in a growing number of countries worried about the power and influence of the United States.

In 13 of 26 countries, people listed climate change as the top global threat, with the Islamic State militant group topping the list in eight and cyber attacks in four, the non-profit, nonpartisan Pew Research Center said in its report.

Worries about climate change have increased sharply since 2013, with double-digit percentage point increases seen in countries including the United States, Mexico, France, Britain, South Africa and Kenya, according to the poll of 27,612 people conducted between May and August 2018.
