Climate change is among the five most likely and most potentially impactful global risks, according to the just-released World Economic Forum (WEF) 2014 Global Risks Report.

The report assesses 31 risks that are global in nature and have the potential to cause significant negative impact across entire countries and industries if they take place.

An analysis of the five risks considered most likely and most impactful since 2007 shows that environmental risks, such as climate change, extreme weather events and water scarcity, have become more prominent since 2011 (see chart above).

This suggests a pressing need for better public information about the potential consequences of environmental threats, the WEF says.

Concern about socio-economic risks such as income disparity, unemployment and fiscal crises has become more prominent over the years.

The report reveals that fiscal crises and structural unemployment and underemployment are among the most impactful risks while the latter also feature among those most likely to occur. This has knock-on effects on income disparities, which is regarded as the overall most likely risk, the WEF notes.

Cyber attacks and the breakdown of critical information infrastructure also feature among the most prominent risks in this year’s report.

The WEF notes:

This arguably reflects the increasing digitization of economies and societies, where rising dependence on information and data, as well as the systems to analyze and use them, has made attacks more likely and their effects more impactful.”

WEF note: Global risks may not be strictly comparable across years, as definitions and the set of global risks have been revised with new issues having emerged on the 10-year horizon. For example, cyber attacks, income disparity and unemployment entered the set of global risks in 2012. Some global risks were reclassified: water supply crises and income disparity were reclassified as environmental and societal risks, respectively, in 2014.
