John Hopton for redOrbit.com - Your Universe Online Existing power plants worldwide will be responsible for 300 billion tons of future carbon dioxide emissions, with fossils fuels (particularly coal) still proving dominant in energy production. A new study from scientists at Princeton and UC Irvine says that continuing investment in these kinds of power plants makes our targets for controlling climate change questionable. The researchers, whose findings appear in the journal...

Los Alamos National Laboratory Scientists have uncovered key attributes of so-called “brown carbon” from wildfires. Scientists have uncovered key attributes of so-called “brown carbon” from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material’s warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the...

Scientists Suggest Water Vapor Will Intensify Future Climate Change Projections
2014-07-30 03:07:27

University of Miami Rosenstiel School of Marine & Atmospheric Science A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere – a key amplifier of global warming – will intensify climate change impacts over the next decades. The new study is the first to show that increased water vapor concentrations in the atmosphere are a direct result of human...

New Study Suggests Saharan Dust Is Key To The Formation Of The Bahamas Islands
2014-07-29 03:25:35

University of Miami Rosenstiel School of Marine & Atmospheric Science UM Rosenstiel scientists studied how fertilization of region could trigger carbonate formation A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to produce the island chain's...

Gina Hebert, Marine Biological Laboratory What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers — organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection. The June issue of the Biological Bulletin, published by the Marine Biological Laboratory, addresses the challenges faced by these species as ocean composition changes worldwide. As atmospheric...

The surprising facts about indoor air pollution are sobering, but the risks can be reduced through efficient air filtration. NEW YORK, July 19, 2014 /PRNewswire-iReach/ -- Air Filtration News - With the average American spending some 90 percent of their time indoors, the quality of indoor air is of paramount importance for health, productivity, and comfort. Yet while many individuals are aware of -- and rightly concerned by -- high levels of outdoor air pollution, one statistic may...

Surface Analysis Features
2012-09-03 16:09:19

The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such as cumulus or stratus. The second is the black circle found in the Dakota’s. Here we are...

Surface Weather Map Features for July 5, 2012

The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...

Cumulus-nimbus Clouds
2014-01-11 00:00:00

The image above shows a Cumulus-nimbus cloud that has an anvil top to it. The reason that can be identified is that the cirrus is in place above the center of the storm. The image below does not have an anvil top yet. The anvil top forms on CB clouds after they reach the height in the atmosphere where they begin to feel the upper level winds becoming too strong for them to continue development vertically. The storm on the right has not felt the upper level winds yet, that is why it lacks the...

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 was...
