Warm Seas Melting Antarctic Ice Sheet Faster Than Expected
2012-12-07 13:15:29

April Flowers for redOrbit.com - Your Universe Online The West Antarctica ice sheet is melting faster than expected. An international group of oceanographers led by the University of Gothenburg has published new observations in the journal Nature Geoscience that may improve our ability to predict future changes in ice sheet mass. The water levels of the oceans would be affected globally by a reduction of the ice sheets in Antarctica and Greenland, making it problematic that...

Powerful Magnitude 7.0 Earthquake Rocks Japan, Touches Off Small Tsunami
2012-12-07 09:00:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Japan, still reeling with the aftermath of a powerful earthquake and destructive tsunami in March 2011, has been hit again. A magnitude 7.3 earthquake struck off the coast at 5:18 p.m. local time Friday evening triggering a small 3-foot-high tsunami that swept against the Japanese mainland nearly 45 minutes later. Evacuation orders came streaming in over TV and radio channels shortly after the quake struck and countless coastal...

Climate Forecasts In The Long Term Need Work
2012-12-07 08:13:29

April Flowers for redOrbit.com - Your Universe Online A research team from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) has evaluated 23 current climate models to assess their ability to predict the weather conditions for the coming year or even the next decade. They concluded that there is still a long way to go before reliable regional predictions can be made on these scales, as none of the models assessed is currently able to forecast the...

On December 6, NOAA will release a technical report that estimates global mean sea level rise over the next century based on a comprehensive synthesis of existing scientific literature. The report finds that there is very high confidence (greater than 90% chance) that global mean sea level will rise at least 8 inches (0.2 meters) and no more than 6.6 feet (2 meters) by 2100, depending upon uncertainties associated with ice sheet loss and ocean warming. The actual amount of sea level change...

Government Agency Proposes Dozens Of Coral Species For Endangered Species Act
2012-12-03 16:06:58

Lee Rannals for redOrbit.com — Your Universe Online A new Endangered Species Act listings proposed by the National Oceanic and Atmospheric Association (NOAA) would cover 66 coral species found in the Pacific and the Caribbean. NOAA said that in 2009, it received a petition to list 83 species of reef-building corals under the ESA from the Center for Biological Diversity. The organization found that the Center presented substantial information indicating a listing under the ESA...

Ice Sheet Loss At Both Poles Is Clearly Increasing
2012-11-30 08:10:18

April Flowers for redOrbit.com - Your Universe Online In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date. Published in the journal Science, the landmark study shows that the melting of the Antarctic and Greenland ice sheets has contributed 11.1 millimeters to global sea levels since 1992, amounting to one fifth of all sea level rise over the survey...

New Trends In Climate Change Sweeping The Globe
2012-11-29 14:50:10

Enid Burns for redOrbit.com — Your Universe Online The year is shaping up to be a warm one. A report released by the World Meteorological Association (WMO), the provisional annual statement on the state of the global climate, highlights a warming trend experienced during the first 10 months of 2102. The organization finds that despite La Niña occurring early in the year temperatures were the ninth warmest annually since records began in 1850. La...

Research Shows Sea-Level Rise Is Much Faster Than Previously Reported
2012-11-28 12:18:17

Lawrence LeBlond for redOrbit.com - Your Universe Online The Intergovernmental Panel on Climate Change (IPCC) has been keeping a close eye on rising sea levels and has released several reports outlining the forecasts for the future of our world´s oceans. In its fourth assessment report, released in 2007, the IPCC estimated sea levels were rising at a rate of 0.08 inches per year based on satellite data. But new research from the Potsdam Institute for Climate Impact Research, Tempo...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

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...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...

Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
