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...

Rising Temperatures Will Lead To Cataclysmic Changes Unless More Is Done Now
2012-11-19 11:07:17

Lawrence LeBlond for redOrbit.com - Your Universe Online The heat is rising and all nations around the globe will likely feel the sweltering effects of a 7.2-degree F increase by the end of the century, unless more is done now to curb climate change.  But while the world as a whole will feel this climatic impact, none will suffer more than the world´s poorest countries, according to a new report by the World Bank. This global temperature increase will trigger a cascade of...

Rising Temperatures Could Lead To Sea Levels Rising Three Feet Or More
2012-11-15 13:56:59

April Flowers for redOrbit.com - Your Universe Online A rapid response between global temperatures and ice volume/sea-level that could lead to sea-levels rising by over 3 feet have been revealed by a new study from the University of Southampton. Global ice-volume variability has been one of the main feedback mechanisms in climate change during the last few million years. This is because of the strong reflective properties of large ice sheets. Scientists reconstruct ice volume...

Climate Change Bad News For US Military
2012-11-11 09:43:38

redOrbit Staff & Wire Reports — Your Universe Online Food shortages, natural disasters, energy supply issues and the spread of epidemics are some of the possible climate-related perils the U.S. military needs to prepare to deal with, the National Academies claim in a new report released Friday. According to Suzanne Goldenberg, U.S. Environment Correspondent with The Guardian, the report advises American defense personnel to "start planning for natural disasters, sea-level...

What Triggered Earth's Last Big Freeze
2012-11-06 09:53:08

April Flowers for redOrbit.com - Your Universe Online Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate. This debate concerning the melt, which ushered in the last major cold episode about 12,900 years ago, has been raging for about 30 years. A research team from the University of...

Global Warming 250 Million Years Ago Triggered Slow Species Recovery
2012-11-05 12:49:52

Brett Smith for redOrbit.com - Your Universe Online After a major extinction event occurred 250 million years ago, many species that survived had a long, slow recovery, which was exacerbated by the effects of global warming, according to a new study presented at the Geological Society of America meeting in North Carolina this week. Ohio State University doctoral student Alexa Sedlacek, in his study, found that rising temperatures, high levels of greenhouse gases and a more acidic ocean,...

Ancient Climate Change Made Hippos Smaller
2012-10-26 11:14:29

April Flowers for redOrbit.com - Your Universe Online Have you heard of giant hippopotamuses wandering along the banks of the Elbe in Germany lately? They are not a common sight today, that is for sure, but 1.8 million years ago, hippos were a prominent part of European wildlife along with other megafauna such as woolly mammoths and giant cave bears. A new study by paleontologists, published in the journal Boreas, claims that the changing climate during the Pleistocene may have forced...

Hula Painted Frog, Discoglossus nigriventer
2014-08-18 15:55:22

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
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...
