Scientific discussions regarding global and existential risks have focused on a variety of catastrophic scenarios. Experts at the United Nations have identified accelerated climate change, nuclear proliferation, geopolitical tensions, economic inequality, and pandemics as primary drivers of potential global disasters. While some historical mathematical models predicted an infinite population peak in late 2026, current demographic trends suggest the global population will instead peak around the mid-2080s.

Research has also expanded into specific planetary threats. Studies suggest that nuclear detonations could potentially disrupt asteroids, though the mechanism relies on X-ray energy release rather than shockwaves. Additionally, researchers have warned that while supervolcano eruptions are not immediate threats, they could cause severe global cooling, crop failures, and supply chain disruptions due to atmospheric sulfur and dust, highlighting a lack of comprehensive global management plans for such events.
