Over the last decade, the number of aerosols in the stratosphere in a country continue to rise. Apart from the use of fuel oil it is also caused by smoke from the eruption of Mount Merapi. Researchers have analyzed several independent sources of satellite and ground some type of instrument. They found a clear increase of aerosols in the stratosphere since 2000.
"Aerosols in the stratosphere has increased by leaps and bounds and shocking at the time, almost doubled during the decade. Increased aerosols since 2000, implying a cooling effect of about 0.1 watts per square meter. This is enough to offset the heat of the sun at 0.28 watts per square meter due to the effects of global warming from increased carbon dioxide during the same period, "added Daniel, told TG Daily, Saturday (23/07/2011).
The increase in a decade daam aerosols in the stratosphere can be caused in part by the resources of nature such as volcanic eruptions are smaller. Then some human activity, which memancaran gases such as sulfur dioxide, which reacts in the atmosphere to form aerosol particles reflective.
If this continues to increase, then the temperature will not heat up quickly. But if they decline, then the temperature will rise even faster. "The background of Aerosols in the stratosphere more than we thought. The last decade has shown us that the eruption of Mount Merapi is not too large so that the aerosol becomes an important part of the climate," he added.
