More Frequent, Bigger Wildfires Burning Western US
2014-04-18 12:26:10

American Geophysical Union Wildfires across the western United States have been getting bigger and more frequent over the last 30 years – a trend that could continue as climate change causes temperatures to rise and drought to become more severe in the coming decades, according to new research. The number of wildfires over 1,000 acres in size in the region stretching from Nebraska to California increased by a rate of seven fires a year from 1984 to 2011, according to a new study...

April Flowers for redOrbit.com - Your Universe Online So far, the spring of 2014 has seen more than 40 percent of the western US in a drought that the USDA has deemed "severe" or "exceptional." In 2013, the drought was just as severe, and in 2012 it spread to the humid eastern states. Looking at the effects of a drought in geological terms, it would be easy to assume that a three-year drought is inconsequential in the long term, despite the devastating effects it might have on farmers...

A recent paper published by Shaun Lovejoy of McGill University, that claims 99.9% certainty of Anthropogenic Global Warming, is flawed from the outset, according to Friends of Science due to Lovejoy’s omission of known climatic variations and reliance on the discredited “Hockey Stick” graph. Calgary, Alberta, Canada (PRWEB) April 17, 2014 Friends of Science are rejecting the recent paper by Shaun Lovejoy of McGill University of Montreal reported on April 11, 2014 in the online...

NASA's AIM Mission Unlocks The Secrets Of Noctilucent Clouds
2014-04-17 08:10:25

[ Watch the Video: Unexpected Teleconnections in Noctilucent Clouds ] April Flowers for redOrbit.com - Your Universe Online When you think about the North and South poles, they seem to be worlds apart. They are separated by four oceans, six continents, and more than 12,000 nautical miles. New data from NASA's Aeronomy of Ice in the Mesophere (AIM) spacecraft suggests, however, that they aren't as far apart as you might think. AIM has revealed "teleconnections" in the planet's...

Bio Logic Aqua Research founder Sharon Kleyne reports on health effects of climate change on skin and eyes, suggests proactive defense. Grants Pass, OR (PRWEB) April 16, 2014 Climate change, drought, and air pollution play havoc with Earth’s atmospheric water vapor - also called “humidity” - reports water and health researcher Sharon Kleyne. Human skin is sensitive to humidity fluctuations, according to Kleyne, because the body relies on the evaporation of water from the skin’s...

Being prepared can solidify one’s home and make restoration an easier task after a flood. These steps by Rainbow International can help you be better prepared for a flood. Waco, Texas (PRWEB) April 16, 2014 Nothing can completely prepare homeowners for a natural disaster, but being prepared can make dealing with one more manageable. Natural disasters like flooding can be expensive to deal with and lack of preparation can be catastrophic for a homeowner. Being prepared can solidify...

Lee Siegel, University of Utah Global warming may bring more curvy jet streams during winter Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East. A University of Utah-led study shows that pattern became more pronounced 4,000 years ago, and suggests it may worsen as Earth's climate warms. "If this trend continues, it could contribute to more extreme winter weather events in North America, as experienced this year with...

Climate Change Hidden Impacts Detailed In New Moth Study
2014-04-15 09:11:36

Brett Smith for redOrbit.com - Your Universe Online A new climate change study conducted on sub-Arctic moths living in Finland has revealed mixed results: moths seem to be thriving despite a warmer, wetter climate – while an as-yet-unknown force is apparently masking the expected effects of this localized climate change. "You see it getting warmer, you see it getting wetter and you see that the moth populations are either staying the same or going up. So you might think, 'Great. The...

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...
