The Freeze was a human-engineered catastrophic event that occurred seven years ago during the boarding of Snowpiercer.
History
Background
It was an attempt to reverse the effects of global warming using CW-7, however it went disastrously wrong and instead caused a massive drop in temperatures which froze the Earth so severely that no life could survive; Snowpiercer and Big Alice carry the only known survivors of humanity.[1]
It is revealed that the temperature outside the train during its passing of Yukon, Canada is around -120 degrees Celsius.
Season 1
While traveling through Yukon, a Class 3 avalanche breaks a window to the Cattle Car, killing all of the cows and workers. Later, Bojan Boscovic is sitting in a room, when a Breach Team opens a door to the part of the exposed Cattle Car and feels the Freeze on his face, before the Team closes the door.
After realizing Andre Layton escaped from The Drawers, Melanie Cavill tortured Josie Wellstead in The Hospitality Car, by using a hose filled with the Freeze and shattered one of her fingers. Later, with help from Bess Till, she freezes the rest of her hand to escape and attempts to kill Melanie by flooding the room with the Freeze. But Melanie escapes and Josie suffers from severe frostbite.
During the Revolution, the Jackboots executed prisoners, such as Walter Flemming, by making them breathe in the Freeze, with the Lung of Ice.
At the end of the Revolution, 7 cars were separated from the train and sent onto a siding. The occupants froze to death in 13 minutes.
Season 2
After suffering a suit breach, causing frostbite to her shoulder and lungs, Melanie discovers snow falling despite the fact that it is supposedly too cold for snow, suggesting that the planet is beginning to recover from the Freeze and to come alive again. After further study, Melanie determines that CW-7 is actually breaking up in the upper atmosphere and falling to the Earth, meaning that the planet will potentially be suitable for colonization again in the survivors' lifetime rather than in a thousand years.
Joseph Wilford brought Snowpiercer to a stop twice, in a attempt to freeze everyone to death, but is foiled both times by Melanie.
During the failed invasion of Big Alice, Icy Bob activated a Freeze deployment system in the Docking Car, that released Freeze air, that injured and killed the invaders and forced them to retreat. Icy Bob also exposes himself to the Freeze, in a sub-zero chamber, in the lab on Big Alice.
After being discovered as Wilford's informant, Pastor Logan commits suicide by breathing in the Freeze, with a hose and bag on his head.
Boki lays the Breachmen to rest by dumping the bodies out of a car, while passing over a bridge. The bodies then shatter upon impacting the frozen surface.
Icy Bob later walks along the top of the train's to sabotage The Engine and later dies aboard Big Alice.
Josie Wellstead later exposed her hand to the Freeze in a chamber opened to the outside and discovered she has resistance to it.
After taking control of the train, Wilford executed the 8 Breachmen murderers (including Eugenia) in a car with the Lung of Ice.
When Josie breached The Aquarium to create the Pirate train, the Freeze killed all fish and turtles, caused the water to freeze and expand (destroying the Car) and killed Bojan Boscovic and 7 Jackboots.
After being recovered by Layton and Alex, Melanie's data shows several areas that are warming in most of Central America and South Mexico, parts of the top and bottom of South America, Spain and southwest Europe, much of the upper parts of Africa as well as the Middle East and Greece, parts of Asia, South Africa and Madagascar, about two-thirds of South Australia and two small spots in the Dominican Republic and South India. However, North America still appears to be completely frozen over with no warm areas.
Trivia
- The mean annual temperature of the interior of Antarctica is -57°C.
- According to Alex, nematodes will survive.
- After the Freeze killed all life on Earth, the only animals left are on Snowpiercer and Big Alice. They include, a pet reptile (in First Class), Erik Sottos cat, fish in a tank (in Jinju Seongs quarters), chickens, goats, pigs, rats with the Tailies or the Headwoods' Lab and a pet dog (Jupiter).
