Latest Arctic haze Stories
HAMPTON, Va., Dec.
â€œBlue haze,â€ a common occurrence that appears over heavily forested areas around the world, is formed by natural emissions of chemicals, but human activities can worsen it to the point of affecting the worldâ€™s weather and even cause potential climate problems.
Much of circumpolar Arctic research focuses on the physical, direct changes resulting from climate warming such as sea ice retreat and temperature increases.
The U.S. space agency says it will soon begin the final weeks of a program studying the effect forest fires have on Arctic climate.
As the summer fire season heats up, NASA aircraft are set to follow the trail of smoke plumes from some of Earth's northernmost forest fires, examining their contribution to arctic pollution and implications for climate change.
Although carbon dioxide and greenhouse gases are known to be the root cause of global warming, scientists have set out in government research planes to determine if airborne particles known as aerosols are also causing the rise in Arctic temperatures.
This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic.
Scientists know that air pollution particles from mid-latitude cities migrate to the Arctic and form an ugly haze, but a new University of Utah study finds surprising evidence that polar explorers saw the same phenomenon as early as 1870.
By Yereth Rosen ANCHORAGE, Alaska (Reuters) - Spring snowmelt in Alaska's Arctic is occurring progressively earlier, accelerating the region's climate change and helping produce its warmest summers in at least 400 years, according to a new study.
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....
