Evidence In Bahamas And Bermuda Suggests Increased Rise In Sea Levels
2012-03-15 11:45:55

Scientists are now predicting sea levels will climb another several inches -- or even a few feet -- by the year 2100, according to recent studies. Studying cliffs and ancient reefs on the sub-tropical islands of the Bahamas and Bermuda, scientists are investigating global sea rise and comparing these results against data from more than a century ago. The Bahamas and Bermuda have been attracting fossil hunters for many years. The land on the Bahamas, for example, is built on a foundation...

Sun's Impact On Earth: What We Need To Know To Prepare For The Future
2012-03-15 05:17:31

Joshua Kelly, Meteorology Correspondent Redorbit.com If you recall back in the year 2000 we were being filled with this information of “global warming” occurring at record setting levels. However, did you also know that in 2009 there were reports of the glaciers in Montana gaining ground and expanding snow cover? So how is it possible that we are going into global warming and then magically just as of recently we now are being told that it´s “climate change.”...

Sturdy Scandinavian Conifers Survived Ice Age
2012-03-04 05:52:45

[ Watch the Video] Until now, it was presumed that the last glacial period denuded the Scandinavian landscape of trees until a gradual return of milder weather began and melted away the ice cover some 9000 years ago. That perspective is now disproved by research headed by Professor Eske Willerslev from the Centre for GeoGenetics, University of Copenhagen, Denmark, Laura Parducci from the University of Uppsala, Sweden, and Inger Greve Alsos from Tromsø University Museum,...

Russian Scientists Reach Ancient Antarctic Lake
2012-02-06 13:55:27

After years of drilling, Russian scientists have finally managed to reach down to reveal a unique sub-glacial lake. The scientists drilled 12,362 feet to reach the sub-glacial Antarctic lake, Vostok, which has been sealed for the past 20 million years. Explorers hope the lake could reveal new forms of life, and show how life evolved before the ice age. The discovery of the hidden lakes of Antarctica in the 1990s sparked enthusiasm from scientists across the globe. Some believe the...

University of Miami study offers new geochemical clues to understand conditions just prior to major climatic event In a study published in the journal Geology, scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that the large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as 'Snowball Earth,' are unrelated to worldwide glacial events. "Our...

How Could Life have Survived 'Snowball Earth'
2011-10-11 08:36:07

Global glaciation likely put a chill on life on Earth hundreds of millions of years ago, but new research indicates that simple life in the form of photosynthetic algae could have survived in a narrow body of water with characteristics similar to today's Red Sea. "Under those frigid conditions, there are not a lot of places where you would expect liquid water and light to occur in the same area, and you need both of those things for photosynthetic algae to survive," said Adam Campbell, a...

Rising CO2 Levels At End Of Ice Age Not Linked To Pacific Ocean
2011-10-03 12:56:29

At the end of the last Ice Age, atmospheric carbon dioxide levels rose rapidly as the planet warmed; scientists have long hypothesized that the source was CO2 released from the deep ocean. But a new study using detailed radiocarbon dating of foraminifera found in a sediment core from the Gorda Ridge off Oregon reveals that the Northeast Pacific was not an important reservoir of carbon during glacial times. The finding may send scientists back to the proverbial drawing board looking for...

Image 1 - New Coral Dating Method Gives Hints Of Possible Future Sea-level Changes
2011-09-12 07:29:54

  New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend, says a research team led by the Woods Hole Oceanographic Institution (WHOI). In a paper published online in the Sept. 11 Nature Geoscience, the researchers report data from an improved method of dating fossil coral reef skeletons in the Bahamas. By calculating more accurate ages for the...

Scientists at the University of York, using an 'amino acid time capsule', have led the largest ever program to date the British Quaternary period, stretching back nearly three million years. It is the first widespread application of refinements of the 40-year-old technique of amino acid geochronology. The refined method, developed at York's BioArCh laboratories, measures the breakdown of a closed system of protein in fossil snail shells, and provides a method of dating archaeological and...

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found By Daniel Stolte, University of Arizona Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found. The study combined paleoclimate records with computer simulations of...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
