Global Dimming

“We thought we live in a global warming world, um but this is actually er not right. We lived in a global warming plus a Global Dimming world, and now we are taking out Global Dimming. So we end up with the global warming world, which will be much worse than we thought it will be, much hotter.”
This was a line from Information Clearing House, the news you won’t find on CNN and if you are interested to view the whole script just visit this site: www.informationclearinghouse.com. In fact, this is true. We are living and experiencing Global Warming and at the same time, the world is undergoing a certain condition called Global Dimming. To tell you honestly dear reader, this is the first time I encountered this word. I just know only about Global Warming. Is it the same with Global Warming or the other way around? Is it beneficial or destructive to us humans and other living things? Let us know more about Global Dimming as we go on, on this reaction. What is Global Dimming and what is it all about? Is it related to Global warming and if it is related, how?
According to wikipedia and others sites that give information on global dimming, it is the gradual reduction in the amount of global direct irradiance at the Earth’s surface that was observed for several decades after the start of systematic measurements. Another site stated that global dimming is indicated by measurements over land areas in many regions in the world and may therefore be a real phenomenon. A change of that magnitude in the incoming solar radiation itself is not possible since satellite observations would have seen it. Thus, it must be something that is happening in the atmosphere to intercept solar radiation.
But what causes this thing? To make this one short, aerosols and the contrails from jets are the best examples for this one. Maybe some would say that this is good to all of us. It’s a big no, because it can kill us. Oh, I almost forgot about the relations between Global Warming and Dimming. They are somehow related. We all know that Global Warming is the increase of the temperature but it is somehow related. Some scientists now consider that the effects of global dimming have masked the effect of global warming to some extent and that resolving global dimming may therefore lead to increases in predictions of future temperature rise.
The pollutants that lead to global dimming also lead to various human and environmental problems, such as smog, respiratory problems, and acid rain. The impacts of global dimming itself, however, can be devastating that why it is called as a killer. Therefore we should not rejoice. It may have been behind the worst climatic disaster of recent times, responsible for famine and death on a biblical scale. And Global Dimming is poised to strike again.
This is a threat for us humans. This is a challenge given by Mother Earth to us. So what we should do now? What are we doing now? Are we waiting for the time that we should look for other planets same like the Earth to shelter us?
As I conclude this statement, it’s not too late to improve our world. It’s just a test for us. We should not wait for the time that we would ride spaceships and rockets just to transfer in a different world. We can still provide some solutions for this growing problem. Honestly, we are now living in a world of extremities. However we can balance it through our own acts.
This is another reaction paper I made when I was in the third year…
