Looming prophecy on the verge of realization?

In a recent study, scientists at the University of Cambridge's Centre for the Study of Existential Risk (CSER) have identified seven volcanoes that, if erupted, could inflict catastrophic damage on civilization. These volcanoes are not super-volcanoes, but their relatively minor eruptions could have outsized global impacts.

The seven critical volcanoes are Krakatoa (Krakatau) in Indonesia, Mount Agung in Bali, Mount Pinatubo in the Philippines, Mount Tambora in Indonesia, and three other volcanoes yet to be named. These volcanoes are particularly concerning because minor explosive events can inject large amounts of sulfuric acid aerosols into the stratosphere, leading to abrupt climate changes and wide-reaching environmental effects.

Krakatoa's 1883 eruption, while relatively moderate in scale, produced vast ash clouds and sulfur aerosols that lowered global temperatures by about 0.5°C for 1 to 3 years afterward. Similarly, Mount Agung's 1963 eruption and Mount Pinatubo's 1991 eruption affected world climate by similar mechanisms, causing significant cooling through atmospheric aerosols. Mount Tambora's 1815 eruption triggered the "year without a summer" in 1816, where widespread crop failures and famine occurred in North America and Europe, underscoring how volcanic aerosol clouds from moderate to large eruptions can dramatically disrupt global agriculture and ecosystems.

The injection of sulfur dioxide (SO2) into the stratosphere forms sulfate aerosols, which reflect sunlight away from Earth and significantly cool surface temperatures globally for up to several years. The cooling can disrupt weather patterns, shorten growing seasons, and lead to crop failures and famine, impacting human civilization far from the volcano site.

Ash clouds and gases also cause immediate local hazards like ashfall, toxic gases, and secondary effects including flooding or tsunamis (if associated with avalanches into seas). The quantities and composition of volcanic aerosols are more climatically significant than just the volume of ash, meaning eruptions that produce large sulfuric acid aerosol layers, even without massive ash volumes, can lead to major global climatic perturbations.

These seven volcanoes pose dangers chiefly due to local effects (lava flows, pyroclastic flows, ashfall) and the potential for tsunamis, especially in the Pacific "Ring of Fire," but the above highlight especially those where relatively smaller eruptions have documented global climatic impacts.

In addition to these seven volcanoes, geophysicists have warned about the potential dangers and implications of super-volcano eruptions, which have occurred in Earth's history. However, this article does not discuss any specific super-volcano eruptions that have occurred recently or are currently building up strength, nor does it discuss any recent powerful earthquakes on Kamchatka that might have woken up volcanoes, or any earthquakes off Kamchatka that could have been triggered by changes in Earth's rotation speed.

In summary, eruptions from volcanoes like Krakatoa, Mount Agung, Pinatubo, and Tambora, although not always “super eruptions,” have shown that moderate volcanic events can inject potent aerosols high enough in the atmosphere to induce global environmental and climatic catastrophes. These seven critical volcanoes, if erupted, could inflict catastrophic damage on civilization by destroying vital global infrastructure, disrupting trade networks and routes, ports, air and maritime transport, and damaging communication lines that support the internet and international financial operations.

1. The study at the University of Cambridge's Centre for the Study of Existential Risk (CSER) has revealed that chronic diseases and health-and-wellness could be affected by climate-change, as minor eruptions of seven critical volcanoes, including Krakatoa, Mount Agung, Mount Pinatubo, and Mount Tambora, can inject large amounts of sulfuric acid aerosols into the stratosphere.
2. Science and environmental-science have shown that the impacts of these volcanic eruptions extend beyond the immediate local hazards; thejection of sulfur dioxide (SO2) into the stratosphere forms sulfate aerosols, which reflect sunlight and lead to global cooling, potentially causing crop failures and famine due to disrupted weather patterns and shortened growing seasons.
3. CBD, a potential natural remedy for many medical-conditions, might also be affected by these global climatic changes, as changes in temperature and precipitation patterns could impact the growth and distribution of cannabis plants, affecting the supply and accessibility of CBD products.
4. As the world becomes increasingly interconnected, climate-change due to volcanic activities could have far-reaching consequences on infrastructure, trade networks, ports, transportation, and communication lines, potentially inflicting catastrophic damage on civilization beyond the direct impact of volcanic eruptions.
