Last Nov, I posted a blog article and produced a podcast episode about the five most "popular" Doomsday Scenarios.
In four different articles alone, and there were 30 different scenarios listed between them. I've cross-referenced the most reputable articles and have created a list of their TOP TEN scenarios.
Scenarios 6-10 are listed here now...ENJOY!!
It shouldn’t be a shock to see that nuclear war made this Doomsday Scenario list. We probably all know that a major nuclear event would cause global destruction and radioactive fall-out. Specifically, nuclear war would cause firestorms (fires so intense that they create their own wind systems), nuclear winter (a global temperature drop of 7-8 degrees Celsius), and radiation sickness. Some theorists predict that even though billions of people would survive the initial effects, they would eventually be wiped out because of the consequent environmental changes, societal collapse and economic breakdown.
An EMP (electromagnetic pulse), or a short burst of energy, could destroy life as we know it. If released in the Earth’s upper atmosphere, an EMP would fry all existing electrical circuits. There would be no cell phones, no radio or television, and certainly no internet. All forms of electricity would cease to exist, throwing mankind back into the dark ages. And you know what that means…rape, theft, and murder galore. Several different types of both natural (lighting) and manmade (power line surge) EMPs exist, but only a few have catastrophic capabilities. Meteoric EMPs can occur if a rogue meteor collides with a spacecraft or breeches Earth’s atmosphere. Coronal Mass Ejections (CMEs), sometimes referred to as Solar EMPs, happen when a burst of plasma (and its accompanying magnetic field) is emitted from the Sun and released into its solar wind. If the burst is large enough, it has the potential to reach Earth. When considering legitimate doomsday scenarios, a nuclear EMP (the result of a nuclear explosion), would be the most likely to cause mass extinction.
Did you know that bees are now an endangered species? People are really freaking out about it. Why? Because bees pollinate 78% of the world’s food supply. Their extinction would not only affect the ecosystem (there are animals that eat bees and honeycomb), it would mean starvation. According to the UN Food & Agricultural Organization, the world has already lost 75% of its crop diversity. People are so concerned about global biodiversity that they have established seed vaults to preserve crops. The Svalbard International Seed Vault in Norway is called the “Doomsday Vault.”
Magnetic Pole Reversal
A magnetic pole reversal is probably the least likely scenario on this list. Also called a geomagnetic reversal, the event occurs when magnetic north and south are switched while geographic north and south remain the same. These reversals have happened several times throughout the Earth’s 4.5-billion-year history and the last one occurred roughly 780,000 years ago. The fear is that if a magnetic pole reversal happened in the span of one 24-hour period, cosmic rays would break through the Earth’s weakened (and maybe even non-existent) magnetic field and kill us all. Fortunately, complete reversals take anywhere from 1,000-10,000 years. A change that slow (relative to human years, of course) would have little to no effect on mankind.
LHC is short for Large Haldron Collider. It resides at CERN (the European Council for Nuclear Research) in Switzerland and is used to create anti-matter. The fear is that this anti-matter would then be used to create a manmade black hole (and we all know how awful THAT would be). Some authorities claim that this would be impossible because the anti-matter particles would disintegrate immediately.
