Global warming is a gradual process of rising atmospheric temperature over a period of time due to host of causal factors. Whereas, climate change is an alteration of climatic setup due to disturbance in major atmospheric elements, including temperature. Both terms global warming and climate change are closely interrelated, as well as interdependent. Hence, independent inquiry of these terms is indispensable to understand the possible impacts on living creatures.
Mechanism of global warming
As we know that global warming is the direct product of carbon induced greenhouse effect. Among all the atmospheric gases, carbon dioxide has a special characteristic in terms of solar electromagnetic waves.
For short waves, carbon dioxide acts as a window but for long waves, it becomes opaque. Hence, the long wave radiation from earth gets trapped in the same degree as the concentration of this element. Consequently, temperature of the globe becomes warmer accordingly.
In simple words, carbon dioxide do not let the long waves radiation to escape as like the short waves; whereby, temperature of the globe rises as per the concentration of element in the atmosphere. This is called the carbon induced greenhouse effect. And, final result is the warming earth’s surface — “global warming”.
Mechanism of climate change
So far, we have learnt that among all the major climatic elements, temperature is called a master factor, and have profound impact on every lives on the earth.
Greenhouse effect is clearly attributed for the disturbance in the natural balance of the climatic elements like, temperature, humidity, pressure, wind etc.
This disturbance in the atmospheric elements results in the radically change in the major climatic phenomenon, such as rainfall, wind system, and humidity.
At last, three decades permanent set up of atmospheric elements start charging theirs properties in respect to one another. It is called “climate change”.
In the layman’s terms, global warming is a cause of carbon induced greenhouse effect that results in the process of change in climatic permanent setup. And, ongoing trail of destruction by natural disasters is the clear cut manifestation of large scale disturbance in the global climatic system.
In this way, carbon dioxide emissions, greenhouse effect, global warming, and climate change are closely interrelated, as well as interdependent negative climatic phenomenon. And, ongoing devastating cyclones, droughts, rise in sea water, are the visible impacts of human interventions in the fragile balance of nature…
