A global catastrophic risk is a possible event or process that can threaten the lives of a large part of humanity, across multiple continents. Humanity today faces a multitude of such risks, ranging from environmental crises to the potentially disastrous consequences of advanced technologies. These risks are rapidly increasing, interconnected, and demand global cooperation to manage.

Some of the most pressing examples of these risks include:

• Climate change
• Ecosystem collapse
• Pandemics
• Weapons of mass destruction
• Potentially disastrous consequences of emerging technologies such as artificial intelligence

Causes of Global Catastrophic Risks

Some catastrophic risks, such as super volcanoes or asteroid impacts, occur naturally, but others are caused by human activities. The development of weapon technologies has expanded our ability to cause widespread destruction. Our consumption and production patterns have affected our climate, decreased biodiversity, and polluted the environment, leading to a planetary crisis.

How risks amplify each other

Many global catastrophic risks are interconnected and reinforce each other in complex loops. Some risks are also linked to tipping points, where even small changes in the conditions could initiate unstoppable and irreversible processes leading to disruptions in the Earth system.

In the climate system, crossing such tipping points could result in the collapse of vital ecosystems like coral reefs, rainforests, and polar ice sheets. Scientists are increasingly alarmed by these cascading effects, which could have severe consequences for human life on the planet.

Rising temperatures and sea levels can also create forced migration, leading to escalating conflicts.

The need for Global Cooperation

The founder of the Global Challenges Foundation, Laszlo Szombatfalvy, emphasized the importance of considering both the probability and severity of potential harms in risk assessment. Even if the chances are low, the potential impact is so great that strong political action is needed to prevent them.

Despite the growing likelihood of events like catastrophic climate change, coordinated global political action remains insufficient.

• The Global Challenges Foundation’s annual report “Global Catastrophic Risks 2017” is based on the latest scientific research. It contains contributions from leading experts, and summarizes the current status of global efforts to manage catastrophic risks. The GCF has also commissioned an international survey, in which 8,000 members of the general public in eight countries have given their views on global risks and how to handle them.
