redOrbit Staff & Wire Reports – Your Universe Online Food shortages, natural disasters, energy supply issues and the spread of epidemics are some of the possible climate-related perils the U.S. military needs to prepare to deal with, the National Academies claim in a new report released Friday. According to Suzanne Goldenberg, U.S. Environment Correspondent with The Guardian, the report advises American defense personnel to "start planning for natural disasters, sea-level rise,...
Alan McStravick for redOrbit.com – Your Universe Online Regardless of which side of the issue you might stand on, regarding climate change and what is going to happen in the future, there is one thing we can all agree on: This summer was HOT! According to a new study funded by NASA, we may want to buckle in because apparently this ride is just beginning and its only going to get hotter. According to analysis by scientists from the National Center for Atmospheric Research (NCAR),...
Brett Smith for redOrbit.com - Your Universe Online The words we choose to use have a big impact on how we communicate. As the 20th century Canadian philosopher Marshall McLuhan once said, “The medium is the message.” A new study from a joint team of U.S. and U.K. investigators has used this idea of word choice to examine how research surrounding climate change has impacted the larger public discourse. For example, a New Jersey scientist is credited with coining the phrase ‘global...
UNITY, Maine, Nov. 6, 2012 /PRNewswire-USNewswire/ -- The following is a statement by Stephen Mulkey, President, Unity College: (Photo: http://photos.prnewswire.com/prnh/20121106/DC07496) We are running out of time. While our public policy makers equivocate and avoid the topic of climate change, the window of opportunity for salvaging a livable planet for our children and grandchildren is rapidly closing. The way forward is clear, though for many confrontation-averse academics...
Brett Smith for redOrbit.com - Your Universe Online After a major extinction event occurred 250 million years ago, many species that survived had a long, slow recovery, which was exacerbated by the effects of global warming, according to a new study presented at the Geological Society of America meeting in North Carolina this week. Ohio State University doctoral student Alexa Sedlacek, in his study, found that rising temperatures, high levels of greenhouse gases and a more acidic ocean,...
Brett Smith for redOrbit.com - Your Universe Online As global warming extends its balmy fingers further into the Arctic regions, defrosting permafrost could release up to 44 billion tons of nitrogen and 850 tons of carbon into the atmosphere, according to a new study from the U.S. Geological Survey (USGS). The doubling of atmospheric carbon that would result from such an unprecedented thaw figures to impact ecosystems, the atmosphere, the Earth’s lakes and rivers, the researchers said...
April Flowers for redOrbit.com - Your Universe Online A new study led by the University of California, Davis finds that more carbon dioxide in the atmosphere, coupled with rising temperatures, is making rice agriculture a larger source of the potent greenhouse gas methane. Relatively simple changes in rice cultivation, according to the study, could help reduce methane emissions. "Together, higher carbon dioxide concentrations and warmer temperatures predicted for the end of this...
At the end of the 21st century, the temperature in the Baltic Sea will be higher and the salt content lower than at any time since 1850. If no action is taken to alleviate the effects of climate change, there may be major consequences for the marine environment. "This is the first time that anyone has taken a detailed look at how climate models and individual factors combine to affect a specific region. This makes this project unique," says Jonathan Havenhand from the Department of...
Michael Harper for redOrbit.com – Your Universe Online Sometimes, the best solution to a problem is the easiest one. The real difficulty lies in the application of said solution. Take, for instance, the issue of global warming and greenhouse gasses. The simplest solution to these matters is to somehow block some of the sun’s harmful rays from the Earth, bringing the temperature down and, ideally, stop the melting of the polar ice caps and other effects of global warming. The difficulty...
Lawrence LeBlond for redOrbit.com - Your Universe Online Life about 250 million years ago was hard to come by. In fact, it was nearly non-existent. Scientists, studying why this period, known as the end-Permian event, lasted so long and have found a key ingredient: heat. Paul Wignall, a paleontologist at England’s Leeds University, and study coauthor, said during the 200,000-year-long Permian extinction the Earth began cooking, with life struggling to thrive, especially at the...

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...
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...
Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...
The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze...
