Climate Change refers to the alteration in the average weather condition of a place over a period of time owing to average temperature changes in the globe. Does this hold any danger ultimately for humanity?
Climate change is a result of global warming; global warming is caused by the greenhouse effect of greenhouse gases. Greenhouse gases include carbon dioxide which takes the largest proportion in the atmosphere, Methane, Flourine compounds and water vapour.
The earth gets heated in the following mechanism; the heat from the sun touches the earth and some of the heat is radiated back to the atmosphere, then some escape and others get trapped by the greenhouse gases. The heat trapped by the gases is used to provide some warmth for the earth otherwise the earth could be too cold. In the same vein high concentrations of these gases provide for excess rapping of this heat which in turn warms the earth excessively and disrupts the working of nature. This has been the trend overtime and has led to natural disasters such as hurricanes,desert encroachment, coastal flooding etc.
This is just but trivializing the profound effects and silent destruction of human life and nature resulting from climate change.
The culprit in all these is not carbon dioxide or other greenhouse gases-its human activities. There are two major factors which are; natural events and human activities. Thats of humans is the most rapid in creating adverse effects on planet earth. Human activities are against the replenishing potential of the environment. With attendant deforestation, nuclear works,electronics,and burning of fossil fuels to power industries the situation has only gotten worse.
The damage has been done gradually, systematically and unconsciously. The question is what have orld leaders done consciously to arrest the situation? The Kyoto protocol has been crafted, talks have been held in Copenhagen and Cancun in Mexico, without much commitment to cut emission of greenhouse gases because of lust for power and economic prosperity. United states,Britain,Japan,Canada on the developed side and Brazil, china and India on the emerging side hold the ace.But they came out without nothing but creation of a fund for little brother Africa for adaptation. Very funny, much of the catastrophe from climate change has been shared by them. With flooding’s in Australia, tsunami in Japan, hurricanes in USA its better they do something early enough.It seems they need the funds more now.
Climate change is killing animals as a result of acidification in sea water.20 per cent of artic ice has melted. If the average temperature increases up to 4 degrees then cereals would be reduced largely then the current food crisis would only be a tip of the iceberg. Very soon twenty three per cent of the chinese would no longer have access to melt glacial water in dry season. Half of Himalayan glaciers would disappear by 2050.
With the ozone layer fast depleting, I hope we don’t suffer from global epidemics and all sorts radiation induced sicknesses.
Finally, I hope one day darkness won’t be on the surface of the deep. If it comes to that I pray creation should provide institutions to curb the excesses of man.If not world leaders would have sat to clear the path that seems to be leading to human destruction.
