GLOBAL WARMING... (BRIEF REPORT)

This post is a very important post. I would request you to please read the entire post and to please put a comment, if possible for you. This post is written to create awareness about Global Warming and it's effects on our lives. If there is any mistake in the data of the post, it will be very kind of you, if you please let me know. I have tried to make this post as simple as possible for every people of this planet to understand, specially those, who come from a non-science background. Global warming affects all of us, so I felt the need to be addressed immediately.


No rainfall in the Northeast and Sudden floods in ‘barren’ Rajasthan, India have left people perplexed over Nature’s Solemn twist. Forget it, here are some other things, which will make you stunned! People in Dubai found snow and parts of Europe saw a blinding heat wave, which killed many, especially the elderly, since they just don’t know how to cope with these unpredictable extremities. In china, thousands of tones of dust settled on the homes of Beijing this summer.

 

The irrefutable scientific truth is that there is an evident increase in the average temperature of the earth’s atmosphere and oceans in recent decades and most of the warming documented over the last 50 years is due to human activities. The increase amounts of carbon dioxide and other green house gases are the principle reasons behind the human – induced reality of global warming. The dangerous phenomenon of climate change is linked to the release and burning of fossil fuels, land clearing and industrial activities.

 

Although carbon can be reduced suddenly and naturally into the atmosphere from volcanic activity, it takes many thousands of years for it to be removed permantly by natural processes such as rock weathering. Global warming has assumed serious proportions and is causing the Greenland ice cap to disintegrate far faster than anyone has predicted. A study of the region’s massive ice – sheet warns that sea levels may as a consequence rise more dramatically than expected. Scientists have found that many Greenland’s huge glaciers are moving at an accelerating rate – dumping twice as much ice into the sea than 5 years ago – indicating that the ice –sheet is undergoing a potentially catastrophic break up.

 

The term “Weather” refers to the day changes in the state of the atmosphere at a specific location. It includes variables such as temperature, humidity, windiness, cloudiness and precipitation. Climate can be defined in the part as the average weather, but the climate of a given region is also defined by the expected year – to – year variation in the weather variables. That is, two regions that have the same mean annual or seasonal temperature, but where one region experiences much greater variation from one year to the next, have different climates. The climate of a given region, however depends on much more than just the atmosphere. It rather depends on all the components that interest together to form part of the climatic system.

 

Now, this climate system consists of the atmosphere, oceans, biosphere, cryoshere (ice and snow) and lithosphere (Earth’s crust). Each of these components influences and is influenced by all of the others, so they form part of a SINGLE SYSTEM. The SUN in contrast, is not part of the climatic system because the climate cannot affect the SUN. Rather, the SUN is said to be the EXTERNAL FORCING>

 

The components of the climatic system are linked by flows of energy and matter. The energy flows occur as solar and infrared radiation, as sensible heat (heat which can be directly felt or sensed) as latent heat (related to evaporation and condensation of water vapour, or freezing and melting of ice) and through the transfer of momentum between the atmosphere and oceans. The major mass flow involves water, carbon, sulphur and nutrients such as phosphorus (P) and nitrate.

 

The behavior of the climatic system depends on how these energy and mass flows change as the system changes, on how the floor themselves influence the system and on the multiple scales with which the system responds to changes in the mass and energy flows.

 

Thus any change in the major mass flows will lead to a disturbed climatic system and thus lead to a natural disaster. This is the time, when you can see a “DESERT INTO A SEA…” Not a joke, but it’s a reality waiting to happen. Well, if I give another example, things will really become horrendous. With reference from the data from the United Nations Weather Agency, the World Meterological Organisation (WMO); the US National Aeronautics and Space Administration (NASA) showed that the hole in the atmospheric layer that guards the world against UV (Ultra-Violet) had grown to 29.5 million square kilometers. The spokesman for WMO; Mark Oliver said, “ This is the most serious on record.”

 

The hole was recorded by NASA was slightly bigger tha the 28 million square kilometers (10.81 million square miles) announced by the European Space Agency. Imagine such a gigantic hole just above us and all the UV rays coming to our Earth! Just Unimaginable! Shocking!

 

Human made green house gases are being released into the atmosphere 30 times faster than at the time when the Earth experienced a previous a episode of global warming. The more we pollute the air, the more music we are going to face. Pollution and emission of harmful gases in the atmosphere, leads to an increase of green house effect leading to Global Warming.

 

At last, this simple brain of mine, is just left with one thought : Is it is a HUMAN MADE DISASTER or NATURE’S WRATH?

 

 

To end I will just quote:

We are the birds of

the same nest,

We may wear

Different skins,

We may speak

Different languages,

We may believe in different religions,

We may belong to different cultures,

Yet we share the same

Home – OUR EARTH.

Born on the same planet

Covered by the same skies

Gazing at the same stars

Breathing the same air

We must learn to happily

Progress together

Or miserably perish together,

For human can

Live individually,

But can survive

Only collectively.”

THANK YOU FOR TAKING YOUR TIME AND READING THE POST.
