Ragnarok: The Age of Fire and Gravel is a book by Minnesota politician Ignatius L. Donnelly published first in 1883. It is a companion to the more well-known work Atlantis: The Antediluvian World .
In Ragnarok, Donnelly argues that an enormous comet hit the earth 12,000 years ago, resulting in widespread fires, floods, poisonous gases, and unusually vicious and prolonged winters. The catastrophe destroyed a more advanced civilization, forcing its terrified population to seek shelter in caves. As cave-dwellers, they lost all knowledge of art, literature, music, philosophy, and engineering (see Ragnarök).
He cites as evidence 900-foot-deep cracks radiating outward from the Great Lakes, and stretching for many miles away. He admits it has been proposed that ice-sheets caused these cracks, but suggests that this explanation is improbable, likening them instead to "cracks in a window which has been struck with a stone". If ice sheets could produce such cracks, he asks, why have not similar cracks been found anywhere else on the globe? He adds to this a discussion of surface rocks in New York City, which seem to have undergone a radical chemical change—the feldspar has been converted into slate and the mica has separated out from the iron, as if they had undergone tremendous heat and pressure, as they likely would in the event that a comet struck the earth. He rules out other theories that could have caused this, such as nitric acid and warm rains, by stating that this is an isolated incident, whereas warm rains can occur at any time and place and there's no archaeological evidence for the nitric acid's origins.
He indicates many legends and myths from various cultures, such as Zoroastrian, Pictish, Hindu, and Ancient Greece, that are all suggestive of a comet striking the earth, the earth catching fire, poisonous gases choking people, and floods and tidal waves swamping large areas. He also discusses early culture's tendency to heliotheism, which he said evolved from gratitude to the Sun, after so many horrific days without it.
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed glacial periods, and intermittent warm periods within an ice age are called interglacials or interstadials.
Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth.
The Snowball Earth is a geohistorical hypothesis that proposes during one or more of Earth's icehouse climates, the planet's surface became entirely or nearly entirely frozen with no liquid oceanic or surface water exposed to the atmosphere. The most academically referred period of such global glaciation is believed to have occurred sometime before 650 mya during the Cryogenian period.
Svante August Arrhenius was a Swedish scientist. Originally a physicist, but often referred to as a chemist, Arrhenius was one of the founders of the science of physical chemistry. He received the Nobel Prize for Chemistry in 1903, becoming the first Swedish Nobel laureate. In 1905, he became the director of the Nobel Institute, where he remained until his death.
Paleoclimatology is the scientific study of climates predating the invention of meteorological instruments, when no direct measurement data were available. As instrumental records only span a tiny part of Earth's history, the reconstruction of ancient climate is important to understand natural variation and the evolution of the current climate.
Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russia rocket engineers) as amyl, is the chemical compound N2O4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol.
Ignatius Loyola Donnelly was an American Congressman, populist writer, and fringe scientist. He is known primarily now for his fringe theories concerning Atlantis, Catastrophism, and Shakespearean authorship. These works are widely regarded as examples of pseudoscience and pseudohistory. Donnelly's work corresponds to the writings of late-19th and early-20th century figures such as Helena Blavatsky, Rudolf Steiner, and James Churchward.
Graham Bruce Hancock is a British writer who promotes pseudoscientific theories involving ancient civilizations and hypothetical lost lands. Hancock speculates that an advanced ice age civilization was destroyed in a cataclysm, but that its survivors passed on their knowledge to hunter-gatherers, giving rise to the earliest known civilizations of ancient Egypt, Mesopotamia, and Mesoamerica.
The geology of Great Britain is renowned for its diversity. As a result of its eventful geological history, Great Britain shows a rich variety of landscapes across the constituent countries of England, Wales and Scotland. Rocks of almost all geological ages are represented at outcrop, from the Archaean onwards.
Tollmann's bolide hypothesis is a hypothesis presented by Austrian palaeontologist Edith Kristan-Tollmann and geologist Alexander Tollmann in 1994. The hypothesis postulates that one or several bolides struck the Earth around 7640 ± 200 years BCE, and a much smaller one approximately 3150 ± 200 BCE. The hypothesis tries to explain early Holocene extinctions and possibly legends of the Universal Deluge.
A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primaeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".
Norse cosmology is the account of the universe and its laws by the ancient North Germanic peoples. The topic encompasses concepts from Norse mythology, such as notions of time and space, cosmogony, personifications, anthropogeny, and eschatology. Like other aspects of Norse mythology, these concepts are primarily recorded in the Poetic Edda, a collection of poems compiled in the 13th century, and the Prose Edda, authored by Icelander Snorri Sturluson in the 13th century, who drew from earlier traditional sources. Together these sources depict an image of Nine Worlds around a cosmic tree, Yggdrasil.
Atlantis: The Antediluvian World is a pseudoarchaeological book published in 1882 by Minnesota populist politician Ignatius L. Donnelly. Donnelly considered Plato's account of Atlantis as largely factual and suggested that all known ancient civilizations were descended from this lost land through a process of hyperdiffusionism.
A New Theory of the Earth is a book written by William Whiston, in which he presents a description of the divine creation of the Earth and a posited global flood. He also postulates that the earth originated from the atmosphere of a comet and that all major changes in earth's history can be attributed to the action of comets. It was published in 1696 and was well received by intellectuals of the day such as Isaac Newton and John Locke.
Parent material is the underlying geological material in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical weathering and the mode by which the materials were most recently transported.
The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma and is ongoing. Although geologists describe this entire period up to the present as an "ice age", in popular culture this term usually refers to the most recent glacial period, or to the Pleistocene epoch in general. Since Earth still has polar ice sheets, geologists consider the Quaternary glaciation to be ongoing, though currently in an interglacial period.
The Withrow Moraine and Jameson Lake Drumlin Field is a National Park Service–designated privately owned National Natural Landmark located in Douglas County, Washington state, United States. Withrow Moraine is the only Ice Age terminal moraine on the Waterville Plateau section of the Columbia Plateau. The drumlin field includes excellent examples of glacially-formed elongated hills.
Herbertingen is a municipality in the district of Sigmaringen in Baden-Württemberg in Germany. The municipality Herbertingen consists of the villages Herbertingen, Hundersingen, Marbach and Mieterkingen. Herbertingen is twinned with Saint-Paul-en-Jarez in France.
Climate change in West Virginia is an ongoing concern. Most of the state has warmed one-half to one degree Fahrenheit (0.28–0.56 °C) in the last century, and heavy rainstorms are becoming more frequent. In the coming decades, a changing climate is likely to increase flooding, harm ecosystems, increase some health problems, and possibly threaten some recreational activities. The average temperature in Charleston, West Virginia, has increased 1.1 °F (0.61 °C) over the last century, and precipitation has increased by up to 10% in many parts of the state.
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. The existence of the greenhouse effect, while not named as such, was proposed as early as 1824 by Joseph Fourier. The argument and the evidence were further strengthened by Claude Pouillet in 1827 and 1838. In 1856 Eunice Newton Foote demonstrated that the warming effect of the sun is greater for air with water vapour than for dry air, and the effect is even greater with carbon dioxide.
