Everything you might want to know about Carbon Offsets
October 31, 2011 07:17 AM - R Greenway, ENN

Companies, and individuals concerned with their impact on climate try a number of measures to reduce their emissions of air pollutants which impact the greenhouse effect of our atmosphere. The greenhouse effect is the reality that our atmosphere traps a portion of the heat we get from the sun, and from fires (both natural and man made) and other anthropgenic heat sources. Some of the gasses released by our industrialization, home heating and cooling, and transportation activities contribute to the atmosphere trapping more heat than would occur in the absence of these activities. There are emissions which CANNOT be eliminated or reduced as much as we would like. For these, companies turn to Carbon Offsets. What are Carbon Offsets? When companies or individuals purchase Carbon Offsets they are paying someone else to reduce THEIR carbon emissions (a major contributor to global warming). There are companies which assist other companies and individuals in purchasing Carbon Offsets. As in any new market, there is a learning curve for participants. Are the offsets real, are the being sold more than once? These and other questions illustrate how much needs to be learned.

A world of sonic wonder

The First wonder, Speaking Sands For nearly a century, man has been baffled by the sound of singing sand dunes. The songs they emit are almost as diverse as the countless theories about how they occur. The sound is produced when the sand on the surface of dunes avalanches. It was once thought that these sounds were produced by the friction between the grains. More recent studies have revealed that the sound continues after the sand has stopped moving and the song that the dunes sing varies depending on the time of year. Some researchers now theorise that the sound is caused by the reverberation between dry sand at the surface and a band of wet sand within the dune, hence it changes seasonally. There are approximately thirty locations around the world where these booming dunes can be heard; the earliest records seem to date to Marco Polo’s time in the Gobi Desert. However you don’t need to adventure among the dunes to hear them sing; the strange sound, said to be like the drone of a low flying propeller plane, has reportedly been heard up to ten kilometres away from its source.
