Genesis
The original reason for testing the atmosphere for trace chemicals was mere scientific interest, but of course, many scientists eventually wondered what effects these trace chemicals could have on the atmosphere, and on life.
The GAW's genesis began as far back as the 1950s when the World Meteorological Organization began a programme of monitoring the atmosphere for trace chemicals, and also researching air pollution from a meteorological point of view. They were also responsible for monitoring ozone, establishing the Global Ozone Observing System (GO3OS) in 1957, in the International Geophysical Year.
In 1968, the United Nations called for an international conference to address world environmental problems caused by rapid industrialization. At about this time, the World Meteorological Organization set up another environmental research body, the Background Air Pollution Monitoring Network. The conference was held in Stockholm in 1972, and addressed several environmental concerns, namely:
- The threat posed to the atmosphere by chlorofluorocarbons (CFCs);
- Acidification of lakes and forests in North America and Europe due to acid rain;
- Global warming caused by build-up of greenhouse gases.
Indeed, it was the World Meteorological Organization's readings and observations that figured prominently at this conference. They had little good news to offer.
The GAW itself was eventually created in 1989 by combining the GO3OS and the Background Air Pollution Monitoring Network. The GAW consists of a worldwide system of observing stations and supporting facilities providing data for atmospheric assessments, and also serving as an early warning system for chemical or physical changes in the Earth's atmosphere which could be cause for environmental concern. Such changes might involve a change in ozone, and therefore ultraviolet, levels, levels of greenhouse gases, or precipitation chemistry, the culprit in the world's acid rain woes.

Famous quotes containing the word genesis:
“Power is, in nature, the essential measure of right. Nature suffers nothing to remain in her kingdoms which cannot help itself. The genesis and maturation of a planet, its poise and orbit, the bended tree recovering itself from the strong wind, the vital resources of every animal and vegetable, are demonstrations of the self-sufficing and therefore self-relying soul.”
—Ralph Waldo Emerson (1803–1882)
“Nature centres into balls,
And her proud ephemerals,
Fast to surface and outside,
Scan the profile of the sphere;
Knew they what that signified,
A new genesis were here.”
—Ralph Waldo Emerson (1803–1882)
“Behold I have given you every herb bearing seed which is upon the face of all the earth, and every tree, in which is the fruit of a tree yielding seed; to you it shall be for meat.”
—Bible: Hebrew Genesis 1:29.
But in a later context, God told the disgraced Adam, “and thou shalt eat the herb of the field” (Genesis 3:18)
