The Menace of Climate Change

The Menace of Climate Change

“The Earth has enough for every­one’s needs, but not for everyone’s greed.”    —Mahatma Gandhi

“Climate Change is happening, humans are causing it and I think this is perhaps the most serious environ­mental issue facing us.”

—Bill Nye

Nature and humankind are two complementary elements on Mother Earth. Their well-being and susten­ance depend on each other. But, man thinking himself the only superpower on Earth, has moul­ded and controlled the nature, over the years, for his every need and deed; forgetting that with the rounding of the clock Nature can give its answer Bak.i Sarkar back. Now, the challenge is before us-the climate change—which we have to face and to tackle in our every breath.

Climate (from Ancient Greek Klima meaning inclination) is com­monly defined as the weather condi­tions prevailing in an area in general or over a long period.

Climate Change is a change in the space and time distribution of weather patterns or conditions or properties of a region or some regions or the entire earth.

Many natural scientists have found in their researches that there are internal and external forcing mechanisms for climate change— internal forcing mechanisms are natural processes within the climate system (like biotic processes, varia­tion in Earth’s orbit, variation in reflexivity of oceans and continents, continental drift and mountain­building etc.) while external forcing mechanisms may be either natural (e.g., changes in solar output) or anthropogenic (human activities like deforestation, burning of waste mate­rials, use of fossil fuel and high energy consumption through electro­
nic gadgets, leading to more emission of green house gases.).

So the term climate change is very comprehensive and includes global warming as well as other changes in weather patterns/ condi­tions due to both human activities and natural processes.

Now, while discussing the menace of climate change, we should first focus on Global Warming, one of the major phenomena of climate change. “There is an air of unreality in debating these arcane points when the world is changing in such dra­matic ways right in front of our eyes

because of global warming”           A1

In normal course, the heat gained by earth gets dissipated to the atmosphere, maintaining the general balance. But increasing concentration of greenhouse gases (GHG) [like carbon dioxide (CO2), Methane (CH4), Chlorofluro Carbon (CFC) etc.] in the stratosphere act as a barrier to this dissipation, thereby resulting in warming of earth. As per National Aeronautics and Space Administra­tion (NASA). “… Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years

……..  the year 2014 ranks as the

warmest on record.”
