Global Dimming| Another Environmental Concern

There is much talk of global warming, but little is known about the phenomenon that is under the scientific research and could also do much harm. “A world in darkness,” the BBC documentary that aired on Discovery Channel, referred to this process which, by reducing solar radiation reaching the Earth’s surface is threatened photosynthesis.
The so-called “global dimming” is produced by the tiny particles floating in the highlands of the atmosphere, smoke from engines and factories, ash from forest fires, and dust created by human activity. All these wastes can reach the stratosphere and retain or reflect sunlight, a situation that results in a darkening but not only a reduction in temperatures worldwide.
According to the BBC documentary, global dimming (GD) would endanger the natural supply of oxygen to the planet, joining the other threats to the vegetation, i.e, the indiscriminate felling of trees for wood and wood burning heating in poor countries.
While this new phenomenon would imply a “hope” to global warming, the studies conducted on the subject indicate that both problems are related because the origin of the pollutants but, being more visible and annoying in the short term, the OG is defined as more severe. However, from now opens a new path in the fight against climate change, since the detection and existing information both global warming and priming, allow scientists to monitor the evolution of this phenomenon combined Threat to
