Introduction to #Global Warming: The Green House Effect

We all know that the #atmosphere has become unbearably hot during summer and the dry season. Those in the western world who are just coming out of the summer season can attest to that. While those of us in Africa are gradually approaching the dry season again in a very short while. These drastic #weather changes are a result of the green house effect. Now, the #green house effect is the warming of the earth’s surface and the air above it. This is caused by gases in the air that trap radiant energy from the sun. The #gases which trap heat are called green house gases. Water vapor is one of the  most common type of green house gas. Others are carbon dioxide and #methane. These #green house gases absorb and emit radiant energy within the thermal infra red rays. Also there are #ozone and nitrous oxide gases. The rest are emitted as a result of human activity.

#Global warming is a long term rise in the temperature of the earth’s climate system which is an aspect of climate change shown by temperature measurements and by multiple effects of this warming. And so therefore, it is apparent that the activity of  the green house gases has had and is still having an adverse effect on the earth’s surface temperature. We can accurately define climate change as changes  in the earth’s climate system resulting in weather patterns that last for at least a few decades and maybe for millions of years. This #climate system comprises of five interactive parts-the atmosphere, #hydrosphere, cryosphere, #biosphere and #lithosphere.

 Now, like I mentioned earlier on, the green gases are namely methane, carbon dioxide and water vapor. As more of these gases trap radiant energy from the sun consistently, the earth’s surface becomes warmer and warmer by the second and minutes, and eventually hours which in turn culminate in a long term rise of earth’s surface temperature resulting in a change in temperature of the earth’s climate system. The underlying causes of global warming are the green gases.

 Furthermore, the activities of green house gases have long term effects. For example, ocean acidification is caused by increased atmospheric concentration of #carbon dioxide gas. Another effect is the long term melting of ice sheets which has contributed largely to a rise in sea levels and consequently flooding of coastal areas on the globe. And as more #ice sheets melt, #evaporation has increased, and has led to increased levels of rainfall on the earth’s surface and more humid conditions. 

Gas flaring of #petroleum gas is another  major cause of global warming. In this case, carbon compounds are released into the atmosphere thereby increasing surface temperatures and the air above it as green gases continue to trap radiant energy from the sun. Surface temperatures increase and subsequently the weather becomes hotter than usual. Yet another cause is the indiscriminate removal of vegetation cover such as trees and plants which are supposed to absorb carbon dioxide and use it up in the photosynthesis process.

 Lastly, the effects of air pollution cannot be overemphasized. Pollution of the air is the major cause of the green house effect. Through air pollution from indiscriminate bush burning, poisonous gases from the exhaust pipes of old and rusty cars and lorries which ply major and minor roads; land pollution from inadequate solid and liquid waste management practices, green gases are introduced into the atmosphere which now trap the heat from the sun, and the resultant effect is #global warming and #climate change.

#Recycling in Developing #Africa

Every day around the world, people throw away things when they are no longer needed or in use. And every day people discard solid #wastes and lots of paper into garbage cans and bags for collectors, or worst still we litter our immediate environment with these wastes. Sometimes, we discard an old shirt or blouse or worn out automobile tyres.   And once in a long while, you discard something really big, perhaps an old refrigerator or a very old car.   Also, after lunch we throw away cans after emptying the contents of a soft drink or fruit juice, and we discard empty bottles of milk after breakfast most mornings. If we were to weigh all these solid wastes it will amount to several millions of metric tons a  year for each country! #Wastes are materials that we can no longer use in our homes, businesses, industries or elsewhere. Actually they are valuable resources and we have not yet learned how to reuse them as fully as possible, especially in Africa. We do reuse or reclai...

A heat wave or....?

As I write this, I am literally dripping in sweat. Why? You may ask.. it’s  the dry season here in Nigeria and subsequently most parts of Western, Eastern and Northern Africa. Nevertheless and despite the fact that we do experience a lot of heat at this time of the year, this is not normal.  Temperatures have hiked feverishly and can be measured at between 37 to 45 degrees and this shows that the sun is high up in the sky and literally burning hot. Well, as I have been saying for a while now, we with our own hands have brought on this demise by own making. First of all, there are major factors which have contributed to this,  and we all know what they are: #air pollution, indiscriminate  removal of vegetation cover as a result of urbanization; and gas flaring, the result of oil drilling and refining. Air pollution as a result of the release of carbon dioxide and  lead oxide emissions into the atmosphere from old and over used vehicles is one major factor. Secon...

#Industrialpollution of Water

Industrial pollution is  a menace to the aquatic ecosystem. Most factories discharge three or four times more oxygen demanding wastes than sewers and they dump poisons into the water as well. Despite the shift from the industrial era to a more integrated approach as regards knowledge and the advancement of technology, this has and can be seen to remedy some of the impacts of industrial wastes. However, some sources may simply have been eliminated. The average wastes gotten from the modern sulphate, pulp and paper process is less than one tenth of what it was from the sulfite process formerly used in paper mills. So in other words, technology has contributed largely to industrial processes to this regard. Still, new and complex chemical processes are on a frequent basis developed and have increased the possibility of releasing dangerous chemical pollutants that are hard to detect and control.  Most industries are always over eager to introduce new chemicals and materials into ...
