A nearly 250 mile (400 km) wide impact zone recently discovered in Central Australia is being called the largest asteroid-caused craters ever discovered, according to research published earlier this month in the international earth sciences journal Tectonophysics.
Have you ever wondered what causes the entire Earth to freeze up and enter an ice age? According to this new study, it's not planetary wobbles like previously thought.
A new study, conducted by scientists at the China National Petroleum Corporation, has found that the same climate forces at work today were also around 1.4 billion years ago – suggesting that current warming observations may be partially due to Earth’s natural climate rhythms.
This, we are told, is the Anthropocene, the Age of Man. But just what does that mean and when did the current age begin?
Environment was just right--a 'Goldilocks effect'-- for well-preserved swim tracks from the Early Triassic age.
Imagine an area the size of West Virginia or Sri Lanka being deforested every year, or devoting an area the size of Norway devoid of trees every five years. Because that's exactly what findings from a new study are showing--which directly contradicts previous studies by the U.N.'s Food and Agriculture Organization's Global Forest Resource Assessment (FRA).

Through the examination of tiny microscopic fossils, a large team of biologists has found that a community of deep-sea microbes hasn’t evolved at all in more than 2 billion years, according to a new studt published in the Proceedings of the National Academy of Sciences.
For years, North American fossils have been the guide post for the late Cretaceous extinction. Now, scientists are finding European fossils have just as much of a story to tell.
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...
- One who brings meat to the table; hence, in some countries, the official title of the grand master or steward of the king's or a nobleman's household.
