In today’s world, it can sometimes feel like we’re facing an overwhelming number of challenges, from natural disasters to geopolitical tensions. But what are the most significant threats to humanity, and how can we address them? Experts from the Global Challenges Foundation in Stockholm and the Center for the Study of Existential Risk at the University of Cambridge explore these questions annually through scientific research.
Some risks are far off in the future, such as cosmic events like gamma-ray bursts from star explosions, which could destroy our ozone layer. There’s also the distant possibility of the universe expanding or collapsing. Closer to home, our Sun will eventually become a red giant, potentially engulfing Earth, but this is expected to happen in about five billion years.
More immediate is the threat of an asteroid large enough to cause a global catastrophe, which is estimated to occur every 120,000 years. Although no such asteroid is currently expected to hit Earth soon, our data is incomplete, and global efforts are underway to monitor the skies. An impact could trigger a global cooling event similar to the Ice Age, affecting both natural and human ecosystems.
Supervolcanoes pose another significant threat. For instance, the eruption of Mount Vesuvius in Pompeii released around four cubic kilometers of magma, but supervolcanoes can release over 500 cubic kilometers. The main concern is the ash cloud, which could block sunlight, cool the planet, and devastate agriculture. The last known supervolcanic eruption occurred about 25,000 years ago in New Zealand, and scientists predict these eruptions may happen every 30,000 to 50,000 years. Yellowstone in the U.S. is currently under observation as a potential future site.
Not all threats are natural. Overpopulation could outstrip Earth’s capacity to produce food and resources, increasing the risk of infectious pandemics, especially with high population densities and the potential for bioengineered diseases. On the other hand, declining fertility rates suggest the human population might gradually decrease. Climate change is another pressing concern; a rise of 3 degrees Celsius could submerge much of Florida and Bangladesh and affect several coastal cities. This would lead to longer wildfire seasons, more destructive hurricanes, heat waves, food insecurity, and droughts, potentially escalating violence in already vulnerable regions and impacting global economic conditions.
Nuclear conflict remains a significant concern. Tensions, such as those involving North Korea, highlight this issue. With over 7,000 known warheads between Russia and the U.S., and nuclear capabilities in other countries like the UK, France, China, India, Pakistan, Israel, and North Korea, the risk is substantial. The Doomsday Clock, created by the Bulletin of Atomic Scientists, symbolizes the likelihood of a man-made global catastrophe. While it now includes climate change and other risks, nuclear war remains a primary focus. Since its inception in 1947, the farthest we’ve been from midnight was in 1991, at 17 minutes to midnight. As of 2017, the clock is at 2.5 minutes to midnight, the second closest it has ever been. Even a small nuclear conflict could lead to a nuclear winter, causing global cooling and ozone layer damage, potentially resulting in prolonged droughts.
Currently, researchers believe the greatest threat may come from artificial intelligence (AI). If AI development continues at its current pace, similar to the industrial and agricultural revolutions, experts predict that autonomous machines could achieve near-human-level intelligence by 2075. Even if these machines do not become malevolent, there are concerns about the consequences if harmful AI falls into the wrong hands or if AI designed for beneficial purposes adopts destructive methods.

With devastating hurricanes, refugee crises, and the real possibility of nuclear conflict, it can sometimes feel like the end is near. But what are the biggest threats to humanity, and is there anything we can do to address them? Experts from the Global Challenges Foundation in Stockholm and the Center for the Study of Existential Risk at the University of Cambridge consider this question annually using scientific research.
Some risks lie millions of years into the future, such as gamma-ray bursts caused by star explosions, which could destroy our ozone layer, or even the potential expansion or collapse of the entire universe. Closer to home, our Sun will eventually become a red giant as it ages and could engulf the entire planet, but that is not expected for another five billion years. More imminent is the threat of an asteroid large enough to create a global catastrophe, estimated to occur every 120,000 years. While none are currently expected to hit Earth soon, existing data is incomplete, and there is a worldwide effort underway to monitor the skies. Should an impact occur, it could lead to a global cooling event similar to the Ice Age. Even smaller asteroids could significantly affect both natural and human ecosystems.
An even closer concern is supervolcanoes. The devastation from Mount Vesuvius in Pompeii released around four cubic kilometers of magma, but supervolcanoes can release more than 500 cubic kilometers. The real worry is the ash cloud, which would block sunlight, cooling the globe and crippling agriculture. The last known eruption occurred around 25,000 years ago in New Zealand, and researchers predict these eruptions may happen every 30,000 to 50,000 years. Scientists are currently monitoring Yellowstone in the U.S. as a potential future site.
Not all threats are natural. Overpopulation can outstrip Earth’s capacity to produce food and other resources, amplifying the threat of infectious pandemics due to high population densities, possibly exacerbated by bioengineered diseases. Conversely, evidence is pointing to declining fertility rates. Will we see the human population gradually decline due to a lack of births, or will climate change become a more pressing concern? A rise of 3 degrees Celsius would be significant, with much of Florida and Bangladesh underwater, while several coastal cities would be affected. Additionally, longer and more damaging wildfire seasons, more destructive hurricanes, heat waves, food insecurity, and droughts could all contribute to increased violence in nations already suffering from water and climate issues, ultimately impacting economic conditions.
Then there’s the threat of nuclear conflict. Tensions over North Korea have brought this issue to the forefront, with over 7,000 known warheads between Russia and the U.S., as well as nuclear capabilities in the UK, France, China, India, Pakistan, Israel, and North Korea. The Doomsday Clock, created by the Bulletin of Atomic Scientists, represents the likelihood of a man-made global catastrophe. While the clock has recently included climate change and other developments that pose risks to humanity, emphasis is placed on nuclear war. Since its creation in 1947, the farthest we’ve been from midnight was in 1991, when the clock was 17 minutes to midnight. As of 2017, the clock sits at 2.5 minutes to midnight, the second closest it has ever been. Even a small nuclear conflict could lead to a nuclear winter, causing global cooling and damage to the ozone layer, potentially resulting in prolonged droughts.
However, researchers currently believe that the greatest threat of all is artificial intelligence. If growth continues at its current pace, comparable to the industrial and agricultural revolutions, experts predict that autonomous machines could attain near-human-level intelligence by 2075. Even if these machines do not become malevolent, there are concerns about what could happen if those programmed to cause harm fall into the wrong hands, or if AI designed for beneficial purposes pursue destructive methods.
