Latest Historical geology Stories
About 635 million years ago, our world was covered in ice during an event called "Snowball Earth," and new details provide a new insight on the duration of this event.
In the March issue of GSA Today, seven scientists from six countries, led by Jan Zalasiewicz of the University of Leicester, propose a realignment of the terms "geochronology" and "chronostratigraphy" in an attempt to resolve the debate of whether units of the Geological Time Scale should have a single (time) or dual (time and time-rock) hierarchy.
While we never managed to find the lost city of Atlantis, an international group of scientists has found evidence of an ancient lost micro-continent resting beneath two islands in the Indian Ocean.
The fact sea levels could rise if the polar ice caps melt has been long established, but according to new research some regions could see greater increases than others.
Not cleaning a kitty’s litter box could be a disgusting thought for cat owners, but for Brian Chase of Montpellier University in France — layers of dried urine can reveal exciting new details about an environment as they stack up year after year and generation after generation.
Speaking before the United Nations Security Council, an official from the Marshall Islands argued that climate change is a threat to international security, citing the impact that global warming has had on his own island nation to illustrate his point.
Scientists have winnowed the precision of the dates regarding the extinction of the dinosaur and the well-known impact that occurred around the same time.
New research findings based on Greenland ice cores show that if climate change patterns repeat themselves, the Earth will become much warmer and sea levels will rise significantly.
A new study has traced glacial ice entering the ocean along the western Antarctic Peninsula using a unique 12,000-year record of microscopic marine algae fossils.
The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...
Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...
The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
