Climate Change Impacts Will Threaten Economy, Public Health
2013-01-29 10:53:50

April Flowers for redOrbit.com - Your Universe Online A leading group of scientists and experts from the United States Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) recently released a report that emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change. The report, titled "Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013...

Why The Weatherman Is Often Wrong
2013-01-25 06:19:05

[ Watch the Video: BYU Engineers Study How Waves Impact Weather, Atmosphere ] redOrbit Staff & Wire Reports - Your Universe Online While it may be easy to blame weathermen when their predictors go horribly, horribly wrong, one US researcher says that the meteorologist may not be to blame — that there are underlying scientific forces at work that can sabotage even the most well-researched forecasts. Those forces are known as internal waves, and according to Brigham Young...

Sea Level Predictions Aided By New Antarctic Geological Timeline
2013-01-16 18:35:25

Alan McStravick for redOrbit.com — Your Universe Online The uncertainty of future sea level rise is getting a little clearer thanks to research being conducted by a team comprised of scientists from the British Antarctic Survey (BAS), the Alfred Wegner Institute for Polar and Marine Research (AWI) and the University of Tromsø. Their study, entitled ℠Grounding-line retreat of the West Antarctic Ice Sheet from inner Pine Island Bay´, is being published in this...

Tsunami Warning Cancelled After Earthquake Off Alaska Coast
2013-01-06 05:09:45

redOrbit Staff & Wire Reports - Your Universe Online Residents of Alaska and parts of Canada were briefly under a tsunami warning on Saturday after a strong earthquake rocked the region, but the alert was later cancelled because no potentially destructive waves resulted from the trembler. According to the United States Geological Survey (USGS), the magnitude 7.5 seismic event took place approximately 58 miles west of Craig, Alaska at approximately midnight local time (08:58:19 UTC)....

Coral Fossils Say 20th Century El Nino Was Intense But Not Unusual
2013-01-04 12:28:23

Watch the video “Examining Fossil Corals” April Flowers for redOrbit.com - Your Universe Online Scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation (ENSO), a Pacific Ocean climate cycle that affects weather patterns worldwide, by examining a set of 7,000-year-old fossilized corals. The teams says that their study will help assess the accuracy of climate model predictions for twenty-first-century climate change in...

Climate Impacts Of Polar Low Arctic Hurricanes
2012-12-17 05:32:40

redOrbit Staff & Wire Reports - Your Universe Online The intense, small scale storms known as polar lows could have a tremendous impact on oceanic water circulation and climate predictions, a team of researchers from the US and UK have discovered. According to scientists from the University of East Anglia (UEA) and the University of Massachusetts at Amherst, the storms, which are also known as Arctic hurricanes, contain areas of extremely low barometric pressure and can produce...

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...

2012-12-06 11:54:11

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...

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...
