postheadericon Climatic Changes

“The events of recent years have reminded us that natural hazards can affect anyone, anywhere in the world. From The Indian Ocean tsunami to the earthquake in South Asia, from the devastation caused by hurricanes and cyclones in the United States , the Caribbean and the Pacific, to the heavy flooding across Europe and Asia, hundreds of thousands of people have lost their lives, and millions their livelihoods, because of these disasters …
Why do we say that they are not that natural? Traditionally, so-called natural disasters have been seen as exceptional events, unpredictable, the result of bad luck or divine punishment. Under this approach they could not be understood or avoided and therefore there was no choice but to resign and concentrate on providing a quick response, when they occurred, to mitigate its terrible consequences. ”

What conclusions could come to upon reflecting about this issue?

Typically we employ terms such as: global warming, greenhouse gases, environmental pollution and greenhouse gas emissions in order to refer to the issue of climatic changes. Another term known as environmental refugees has emerged recently which refers to people who were displaced from their homes by the effects of natural phenomena. According to recent statistics there are already more than 25,000,000 environmental refugees in the world.

We employ the term “Climatic changes” to refer to the changes in climate which have been observed for many years. These changes are largely caused by direct or indirect human activity as well as natural climate variability. The clearing of forests, the carbon dioxide (CO2) produced in the factories and transportation, the methane produced in the agricultural and livestock farms, and the sulfate aerosols from fossil fuels, strongly influence the changes in the chemical composition of the atmosphere. At a practically astronomical magnitude, these climatic changes have become one of the main causes of uncontrollable and devastating phenomena as tsunamis, earthquakes, cyclones, floods, droughts, etc. etc.
