DoomsDay 2012 - Is it true?

Firstly, for those who aren't aware of this sensational topic over the internet in the recent days - DoomsDay 2012. It has been believed by various scientists, historians, philosophers that human civilization will vanish from our motherly earth in the year 2012. There are so many books, videos, blogs sold for this one sensational topic having no substantial proof. Even a movie is going to be released in Nov, 2009 namely 2012. Though i would suggest to watch the trailer of this movie as it has been made to leverage anxiety, excitement, fear & most importantly curiosity in the viewer to watch this movie.

Cause?
The main cause as explained by many scientists is 'pole reversal'.

Earth has it's own magnetic field having the current south & north poles near north & south geographic poles respectively. This magnetic field is assumed to be caused due to the sun's magnetic field.

Now after a time cycle(0.1-25 million years), it is assumed from paleontology study that poles reverse their direction in a span of 5,000 years. During the span, net magnetic field of earth keeps on diminishing.

Effects
With reducing magnetic field:

Radiations from the sun won't be screened well. High chances of cancer in living civilization.

Asteroids are deviated due to earth's magnetic field. Thus, more number of asteroids collision on earth's surface.

Massive plate shifting causing earthquakes, volcanic eruptions etc.

Will it be in 2012?

FOR
Various religions depict this year as the end of the civilization as calenders extrapolated in many religions are till date 2012.

Oracles, Philosophers of the past had a forecast of this year to be the end of civilization.

AGAINST
NASA predicted 2000 years back as all time low in earth's magentic field. Thus, cycle will take another 3000 years to complete.

There hasn't been much research on how earth's magnetic field was formed and after how many years will there be pole reversal. A lot many factors affect this pole reversal like presence of heavyinly planet near earth for creating huge torque, Sun's mangetic field time period etc.

Conclusion
A lot many videos, books and DVDs have been sold in the recent past on the same subject to prove their theories right and taking religious sentiments in play.

There is no accurate prediction of the year 2012 scientifically.

Though, it is true that earth's magnetic field is reducing which will cause major environmental changes and some of which are been observed in present date.

DON'T PLAN ACCORDING TO 2012.

LIVE A HAPPY LIFE.

MORE STRESS ON RESEARCH ON THE SAME TOPIC IS REQUIRED.

Experiencing Global Warming

I as a kid debated on this issue handful number of times without experiences the consequences. My dad told me once that this was also a hit topic during his college days. It has been so long and nothing appreciable has been done to this account.


The year 2009 was an eventful year for me to experience more on global warming personally. Thanks to BBC & Google weather for keeping me updated. A pair of my observations:

1) This year seasons came 2 days early. 2 out of 365 is a whole lot number if we assume in 15 years season shifts by a month!!!

2) Today, Kharagpur's Maximum Temp. was 44 C & Delhi's was 40 C. These both cities are on nearly same latitude while Kharagpur being near sea coast and Delhi having land locked geography. Every year Delhi is hotter than Kharagpur with high margin.

What has these events changed in me:

1) Will i live more than 20 years? I will enjoy my life to the fullest as i am not sure if i will live for more 20 years.

2) I cannot fulfill my dream of settling in a beach house as we have to move towards land to increase our life expectancy.

3) I have to show my children everything as early as possible so that they don't miss the essence of being alive for a short span of time.
