In the last few decades, we have been experiencing severe weather changes in many parts of the world as a result of the creation of man of different chemicals in his quest for more inventions and discoveries. These chemicals often have
ugly adverse effects on the environment in general and the weather in particular.
Lately though, changes in the weather has been exacerbated by significant movements within the Earth itself. Earthquakes in different countries around the world as well as eruptions of long-dormant volcanoes also contribute to alterations in weather patterns. Specifically, when a volcano suddenly erupts, it sends large clouds of gases into the atmosphere. These clouds of gases, which includes
sulfur dioxide, reaches the stratosphere after a major volcanic eruption where they are transformed into smallsulfuric particles called aerosols. Aerosols reflect solar energy, or the energy given off by the sun, and this decreases the amount of sunlight that reaches the Earth's surface. As a result, a temporary cooling of the Earth takes place.
However, major eruptions of volcanoes do not necessarily lead to global cooling. In other areas of the world, volcanic eruptions result in significant temperature decreases. It appears to depend on a variety of factors like the severity of the eruption, the location of the volcano, as well as on the presence of other weather phenomena like the El Nino. Whatever it is, the fact is that a natural catastrophe like a volcanic eruption can lead to drastic weather changes which ultimately affects all of us to a certain degree.
