Arctic Fossil Record Traces Greenland Ice Sheet's Past
2013-11-23 05:24:05

April Flowers for redOrbit.com - Your Universe Online There have been many studies telling us how small the Greenland ice sheet is today. A new study, published in the journal Geology, reveals that the ice sheet was actually smaller between 3,000 and 5,000 years ago. Surprisingly, the sheet was as small during this period as it has ever been in recent history. The international research team used a new technique they developed for interpreting the Arctic fossil record. “What’s...

Extinction Event During End Of The Permian Period Likely Due To Acid Rain
2013-11-23 05:08:21

April Flowers for redOrbit.com - Your Universe Online At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history. Previous research has suggested that contemporaneous volcanic eruptions in Siberia might have triggered this extinction. A new study, published in the journal Geology, reveals that the atmospheric effects of these eruptions could have been...

Moraine Research May Alter Thinking On Climate’s Effect On Glaciers
2013-11-20 07:58:56

redOrbit Staff & Wire Reports - Your Universe Online A Dartmouth College-led study published in the latest edition of the journal Quaternary Geochronology describes a newly discovered, more accurate method to date the soil and rock debris left behind by high altitude tropical glaciers. The research could alter pre-existing interpretations of how climate change affected equatorial ice masses, the study authors explained in a statement Tuesday. Currently, scientists use a variety of...

Algae Reveal History Of Arctic Sea Ice
2013-11-19 12:15:57

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has developed a novel method for tracking changes in Arctic sea ice through the analysis of growth layers of seafloor algae, according to their report in the Proceedings of the National Academy of Sciences. The study found that the algae Clathromorphum compactum accumulates a calcite crust as it grows and changes to this crust over time can be analyzed to reveal historical conditions of the...

Global Warming Linked To Changes In Precipitation Around The World
2013-11-12 05:18:34

[ Watch the Video: Changes In Global Precipitation From Greenhouse Gases ] April Flowers for redOrbit.com - Your Universe Online According to Eliza Doolittle from "My Fair Lady," the rain in Spain lies mainly on the plain. However, according to a new study from the scientists at the Lawrence Livermore National Laboratory (LLNL), the location and intensity of rain is changing around the globe, not only in Spain. The study, published in the online edition of the Proceedings of the...

Dwarfism In Mammals Also Occurred During Second Warming Period
2013-11-03 05:03:03

redOrbit Staff & Wire Reports - Your Universe Online While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum (PETM), researchers from the University of Michigan have found a second instance of mammalian “dwarfing” attributable to increasing temperatures. During the PETM, which occurred approximately 55 million years ago, mammals such as primates and groups that include deer and horses...

Atmospheric Cooling Could Be Result Of Oceanic Heat Absorption
2013-11-01 08:41:05

redOrbit Staff & Wire Reports - Your Universe Online The apparent stabilization of atmospheric temperatures over the past decade -- often cited by climate change skeptics as evidence that global warming has slowed down or stopped -- is actually caused by a radical increase in the amount of heat being absorbed by the oceans, according to a new study. Yair Rosenthal, a climate scientist at Rutgers University, and colleagues report that the ocean is now absorbing heat 15 times faster...

Importance Of Climate Protection Misguided
2013-10-24 09:21:50

April Flowers for redOrbit.com - Your Universe Online Collective risks are hard for people to grasp. A good example of this is climate change. Despite annual climate summits, no specific measures have arisen, because people place greater value on immediate material rewards than on investing in future quality of life. To change this, cooperative behavior in climate protection needs to be more strongly associated with short-term incentives, like rewards or being held in high esteem. Would...

Seasonal Drying In The Amazon Has Greater Impact Than Thought
2013-10-22 07:05:04

redOrbit Staff & Wire Reports - Your Universe Online New research suggests that the southern part of the Amazon Rainforest faces a higher risk of dieback (the gradual dying of plant shoots beginning at the tip) as a result of seasonal drying than reported by climate models used by the most recent Intergovernmental Panel on Climate Change (IPCC). Furthermore, University of Texas at Austin Jackson School of Geosciences professor Rong Fu and her colleagues report that severe loss of...

Plant Mapping Project Highlights Where Rarest Species Thrive
2013-10-17 15:35:22

Lee Rannals for redOrbit.com - Your Universe Online An international group of researchers has created the most comprehensive map of rare plants to date. The new map, published in Ecology Letters, shows how climate stability plays a crucial role in the distribution of plants on Earth. It shows that rare species in the Americas are located in California, Mexico, the Caribbean islands, parts of the Andes mountains, the south of South America, and the region around Rio de Janeiro. "This...

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...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
