[ Watch the Video: Wildfires Heated Up The Early Earth ] Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Geophysical Research Letters, wildfires could explain why the Earth was so hot three million years ago. Researchers at Yale University found that volatile compounds released by ancient Earth’s forests and smoke from wildfires caused more global warming than atmospheric levels of carbon dioxide. This study provides evidence...

Air pollution in China has exhibited noticeable changes over the past 30 years, shifting from point-source pollution (around factories and industrial plants) in the 1980s to urban pollution in the 1990s. Since the start of this century, air pollution has become increasingly regional and more complex. Recent research has indicated that the cooperative transition of SO2 and NOx into secondary aerosols (sulfate and nitrate) played a critical role in the haze pollution episode in China in January...

Asian Air Pollution In Hawaii Is Tied To Climate Variability
2014-01-28 12:48:57

Princeton University Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found that shifts in atmospheric circulation explain the trends in Hawaiian ozone pollution. The researchers found that since the mid-1990s, these shifts in atmospheric circulation have caused Asian ozone pollution reaching Hawaii to be relatively low in spring but rise significantly...

A gas mask is designed to go over the face to protect the wearer from inhaling "airborne pollutants". The mask seals the nose and mouth and many times covers other soft tissues of the face. Some have respirators. Most gas masks provide protection from gaseous and particulate and are often used by riot police and rioters alike. They are also used by graffiti artists to protect them from the fumes. The original design had two small glass eye windows that were thick in order from keeping 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...

Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....

Mist is a phenomenon that consists of small droplets of water suspended in air. Mist occurs as part of a natural weather event or from volcanic activity. Mist is most common in cold air above warm water. Mist also occurs when air is exhaled in cold temperatures or when steam is formed in a sauna. Aerosol cans can create artificial mist if the humidity levels are just right. The one difference between mist and fog is visibility. If visibility is less than 0.62 miles (1 kilometer), the...
