BMJ-British Medical Journal Death toll may be higher because of exodus of displaced persons to other locales Hurricanes Katrina and Rita may have been responsible for up to half of all recorded stillbirths in the worst hit areas, suggests research published online in the Journal of Epidemiology & Community Health. And the true fetal death toll may even be higher, because of the displacement of people whose homes and way of life were destroyed, suggest the authors. Hurricane...

NASA's ACCESS II Alternative Jet Fuel Flight Tests Begin Today
2014-05-09 03:43:26

[ Watch The Video: Falcon 20-E5 Aircraft Flies Close Behind NASA DC-8 To Sample Exhaust ] NASA NASA took to the skies today -- along with international partners the German Aerospace Center (DLR) and National Research Council of Canada (NRC) -- to begin a series of flight tests to gather critical data that may aid in the development of cleaner aircraft fuels. The flight tests over Palmdale, California, called Alternative Fuel Effects on Contrails and Cruise Emissions II (ACCESS...

Understanding How Sprites Form
2014-05-08 03:55:14

By A'ndrea Elyse Messer, Penn State Atmospheric sprites have been known for nearly a century, but their origins were a mystery. Now, a team of researchers has evidence that sprites form at plasma irregularities and may be useful in remote sensing of the lower ionosphere. "We are trying to understand the origins of this phenomenon," said Victor Pasko, professor of electrical engineering, Penn State. "We would like to know how sprites are initiated and how they develop." Sprites are...

New Evidence That Human Activities Are To Blame For Global Warming
2014-05-06 13:40:37

Brett Smith for redOrbit.com - Your Universe Online A new federally-mandated report released on Tuesday has provided more evidence supporting the idea that global warming is indeed happening and that human activity is the cause. “Multiple lines of independent evidence confirm that human activities are the primary cause of the global warming of the past 50 years,” the report said. “The burning of coal, oil, and gas, and clearing of forests have increased the concentration of carbon...

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by NCAR. The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050. Boulder, CO (PRWEB) May 05, 2014 Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National...

US Corn Yields Growing More Sensitive To Heat And Drought
2014-05-02 03:13:58

By Laura Seaman, Stanford University Corn yields in the central United States have become more sensitive to drought conditions in the past two decades, according to Stanford research. The study, which appears in the journal Science, was led by Stanford's David Lobell, associate professor of environmental Earth system science and associate director of the Center on Food Security and the Environment. "The Corn Belt is phenomenally productive," Lobell said, referring to the region of...

Tree Rings Reveal A History Of Drought In Utah
2014-05-02 05:21:34

Brett Smith for redOrbit.com - Your Universe Online New research on tree rings in Utah has revealed that some droughts of the past 576 years were much more severe than anything seen since the start of the 20th century. The study team said tree rings provide a much longer historical record than climate and stream flow logs, which only go back about 100 years. According to the team’s report in the Journal of the American Water Resources Association, the most severe drought of this...

Friends of Science are calling for a retraction of a controversial paper by Stephan Lewandowsky, published in Psychological Science, that claims climate change critics are hoax and conspiracy theorists who allegedly believe "NASA faked the moon landing." Friends of Science recent study that shows there is not a 'more than 90%' consensus as claimed by Lewandowsky, as a principal premise of his study; recent IPCC climate science reports confirm that there has been a hiatus...

Urban Heat Island
2013-04-02 15:35:21

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that 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...

Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
