Air Pollution Increases Worldwide
2012-08-01 12:22:05

Atmospheric model calculates changes in air quality over the coming decades Hot summer days cause in large cities very seldom great happiness among inhabitants. On those days the air is highly polluted with automobile and industrial emissions what makes breathing difficult and unhealthy. According to the latest calculations of Max Planck scientist Andrea Pozzer this scenario could become true for most of world population in 2050 if no counteractive measures are taken. Especially China,...

The destruction of atmospheric ozone can take place within newly forming Polar Stratospheric Clouds (PSCs), which serve as the battleground for manmade chlorofluorocarbons (CFCs) to attack and destroy ozone. These clouds form when clusters of frozen water "pick up" other atmospheric molecules such as methane, nitrogen oxides, and water molecules, similar to the way a snowball's girth increases as it rolls down a mountainside. Most previously established atmospheric models have assumed that a...

Summer Storms Cause Ozone Depletion In United States

Lawrence LeBlond for redOrbit.com - Your Universe Online It was in the 1970s that the British Antarctic Survey discovered a hole in the ozone layer above the Antarctic Circle, and in 1985, when the first measurements were taken, researchers were dumbfounded by the dramatic drop in ozone levels. The concern was so great that it eventually led to the ban of all products containing chlorofluorocarbons (CFCs), which were confirmed to be the root cause of the ozone depletion. Fast forward...

Reign Of Acid Rain Is Far From Over

New connection between climate change and acidification of Northeast's forests and streams Acid rain. It was a problem that largely affected U.S. eastern states. It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds--and rainfall--acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients. New England's sugar maples were among the trees left high and...

Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade. More than 15 years of atmospheric observations have revealed trends in air quality. As the world´s population increases, economies in many countries are also growing and populations are concentrating in large cities. With the use of fossil fuels still on the rise, pollution in large cities is also increasing. Nitrogen dioxide is an important...

Nitrogen Pollution Changing Rocky Mountain National Park Vegetation
2012-07-05 13:40:38

A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park. The emissions of nitrogen compounds to the atmosphere are being carried to remote areas of the park, altering sensitive ecosystems, said CU-Boulder Professor William Bowman, who directs CU-Boulder's Mountain Research Station west of Boulder and who led the...

Michael Crumbliss for redOrbit.com China has the worst pollution problems in the world. And it is getting worse as the utterly unchecked rush to industrialization continues. Much of this is pollution is linked to coal mining and power generation, but the sources of toxins are myriad. While air and water pollution are highly visible and overwhelming on an everyday basis, the worst long-term toxic buildup may be lurking quietly underfoot in the soil. Nowhere is the global push to restore...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Today's soil contamination is a direct result of man-made chemicals or other changes in nature's soil environment. This contamination most commonly occurs from underground storage tanks bursting, use of pesticides, discarding oil and fuel illegally, leakage of dirty surface water, draining of wastes from landfalls and knowingly dumping industrial wastes into the soil. The most widespread chemicals found are petroleum hydrocarbons, solvents, common pesticides, lead and additional heavy metals....

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
