Greenland Ice Core Research Points To Higher Seas, Warmer Past
2013-01-24 11:07:31

Brett Smith for redOrbit.com - Your Universe Online 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. In a new report published in the latest edition of the journal Nature, scientists have used Greenland ice cores over 1.5 miles long to collect data on the Eemian period, around 115 to 130 thousand years ago. An analysis of the cores allowed the international...

Algae Fossils Help Unlock Climate Change Secrets
2013-01-23 10:46:06

April Flowers for redOrbit.com - Your Universe Online One of the fastest warming regions on the planet — and the fastest warming part of the Southern Hemisphere — is the western Antarctic Peninsula. This warming has been the subject of scientific debate, especially in light of recent instrumental records of both atmospheric and oceanic warming from the region. Holding an equivalent of 5 meters of global sea level rise locked in ice, the Antarctic ice sheet is becoming...

Dramatic Glacial Melting In Andes Blamed On Climate Change
2013-01-22 13:47:37

Alan McStravick for redOrbit.com - Your Universe Online Only four months ago and a continent away, researchers were looking into the varying degrees of ice accumulation and ablation within the Himalayan glacial system. In that report, published by the National Research Council (NRC), the team concluded that glacial melt could pose significant issues for the native populations that depend on the water runoff from these glaciers for their day-to-day lives. An international team of...

Greenhouse Gas Associated With High Sea Levels Over Past 40 Million Years
2013-01-03 09:12:39

April Flowers for redOrbit.com - Your Universe Online Researchers based at the National Oceanography Centre, Southampton, have found that greenhouse gas concentrations similar to the present — almost 400 parts per million - were systematically associated with sea levels at least 30 feet above current levels by comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years. The study, published online in the Proceedings of the National...

Dinosaur Fossil Smuggler Pleads Guilty
2013-01-01 05:47:14

April Flowers for redOrbit.com - Your Universe Online Eric Prokopi, a Florida fossils dealer, has pled guilty to smuggling charges. He has agreed to give up the $1 million Tyrannosaurus bataar skeleton seized by the U.S. government earlier this year after he attempted to auction it through Heritage Auctions. Prokopi is giving up "Ty," the T. bataar that will eventually be returned to Mongolia, along with six other dinosaurs and various other bones in a deal that might win him a little...

Compares glacial to global warming. Marlborough, MA, (PRWEB) December 13, 2012 “Tale of the Northwest Passage” has been published to YouTube. This third video in a series compares current climate change to changes observed on a glacial scale. It is the second available on YouTube. “These videos were created as a scientific appendix for the hard Science Fiction eBook Time Arc, a cautionary tale of time travel, and a compelling tale of global warming,” said Frank...

Ediacaran Fossils A 'First-class Scientific Mystery'
2012-12-13 08:50:07

redOrbit Staff & Wire Reports - Your Universe Online Mysterious multicellular fossils believed to be ancient sea creatures may actually be some of the earliest land-dwelling organisms, according to a paper published online on Wednesday in the journal Nature. The controversial hypothesis has been fiercely criticized, with some paleontologists flatly rejecting the idea, but if true, the finding would push back life's transition from sea to land by as much as 100 million years or more....

Scientists Name Extinct, Ancient Lizard After Obama
2012-12-11 05:12:51

Lee Rannals for redOrbit.com - Your Universe Online Despite the name, a new species of lizard reported about in the scientific journal Proceedings of the National Academy of Sciences is not related to our President, because it went extinct when the giant asteroid hit Earth millions of years ago. Obamadon gracilis was one of the lizard species that suffered from the asteroid event that ended the reign of the dinosaurs 65.5 million years ago. Previous studies suggested that some snake...

New Test Helps With Understanding Earth’s History And Resources
2012-12-06 10:18:32

University of Florida A new study co-authored by a University of Florida researcher provides the first direct chronological test of sequence stratigraphy, a powerful tool for exploring Earth´s natural resources. The model allows geologists to better understand how sedimentary rocks are related to one another in time and space and predict what types of rocks are located in different areas. The information may help scientists more reliably interpret various aspects of Earth´s...

Paleontology
2014-01-12 00:00:00

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
2013-04-19 19:33:20

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
2013-04-01 11:05:27

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...

Geologic Clock With Events And Periods
2012-11-18 19:10:56

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...

Geologic Clock With Events And Periods

The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
