Section Three of Global Warming - The Big Picture:

Greetings, everyone should be concerned about the issue of Global Warming because it will be your taxes that will be used to reduce your life style if Al Gore and the other Carbon Climate Clowns gets their way.

To really understand Global Warming it is best to start by looking at the Big Picture, that is, the big movements of temperature for at least the last 420,000 years. Fear not, this exercise will not take long, merely a five minute primer on Global Warming, showing you the picture you need to see in case someday someone insists on talking to you about Global Warming - you will need protection - the best protection is knowledge of the subject. It is time to start your education of Global Warming.

The temperature of our planet is not static, it's erratic, wandering up and down all the time. Every now and then the temperature will rise about twenty F degrees - I call these movements Global Warmings. Without these warm periods, our planet would be locked into a continuous ice age, a Major Ice Age. Since the start of the Major Ice Age two million years ago, there have been about twenty Global Warming Periods. They average about one hundred thousand years apart, but they do not come like clockwork exactly at one hundred years, they come between 80 and 120 thousand years apart. My charts in Section One starts with the Global Warming of 420 thousand years ago. Since then there have been four more periods of Global Warming including our current Global Warming period which began 11.5 thousands years ago - it seems that a warm period is said to start when the average temperature goes above fifty-five F degrees. When the average temperature goes below fifty-five degrees, that will mark the end of a Global Warming period. Our current Global Warming Period may take as long as twenty thousand years before it ends.

These Global Warmings periods are also known as Interglacial Warm Periods, which means a warm spell between two glacial periods, but this is not a good term because most Global Warming periods were not between two glacial periods. Two million years ago there were no glaciers, so it would have been best to call them Interwarm Hot Periods, which would have meant a hot spell between two warm periods. Global Warming merely means a rise of temperature of about twenty F degrees. It may be from warm to hot or cold to warm - everything is relative, but I digress.

Anyway, what follows are charts that show the wandering nature of global temperatures from 420,000 years Before Present (BP), Present being the year 2000 AD.

Temperature readings for these charts were taken from the following site: http://cdiac.esd.ornl.gov/ftp/trends/temp/vostok/vostok.1999.temp.dat

These are the Historical Isotopic Temperature Record from the Vostok Ice Cores. I consider this data set to be the standard. Acknowledgement is at the end of the this file.


Section Three - Chart One of Three Charts:

(A) HIGH; A peak of 61.34 F degrees, 410,489 years ago before 2006 AD.
(B) LOW: Down to 44.53šF, 333,608 years ago.
(C) HIGH: Spike of 62.94šF, 322,644 years ago.
This is what Global temperatures do, they spike up and then cool down, only to spike up again and again and again, etc.

Section One - Part Two of Three Parts:

(D) LOW: Down to 41.77šF, 265,601 years ago.
(E) HIGH: Spike of 61.16šF, 237,981 years ago.
(F) LOW: Down to 40.57šF, 138,109 years ago.
The peak at 215K BP years is not considered to be a Global Warming Period by itself, but a part of the Global Warming peak of 237,981 years ago.

Section One - Part Three of Three Parts:

(G) HIGH: Spike of 63.01šF, 128,363 years ago.
(H) LOW: Down to 40.96šF, 27,116 years ago.
(I) HIGH: Spike of 60.91šF, 8,141 years ago.
Eight thousand years is not too long ago when we consider how far we have traveled in time since 420,000 years ago. And yes, 60.91šF is the high peak of our current Global Warming period. It has been eight thousand years since and we are still below that top peak of temperature today. Since the peak, temperatures have been going sideways wandering up and down between fifty-five and sixty degrees F.

This is the end of Section Three.
