I was right- they lied.

Concept
Scientists have long recognized a connection between electricity and magnetism, but the specifics of this connection, along with the recognition that electromagnetism is one of the fundamental interactions in the universe, were worked out only in the mid-nineteenth century. By that time, geologists had come to an understanding of Earth as a giant magnet. This was the principle that made possible the operation of compasses, which greatly aided mariners in navigating the seas: magnetic materials, it so happened, point northward. As it turns out, however, Earth's magnetic North Pole is not the same as its geographic one, and even the pole's northerly location is not a permanent fact. Once upon a time and, in fact, at many times in Earth's history, the magnetic North Pole lay at the southern end of the planet.
How It Works

Electromagnetism
The Greek philosopher Thales (640?-546 B.C.) was the first to observe that when amber is rubbed with certain types of materials, the friction imparts to it the ability to pick up light objects. The word electricity comes from the Greek word for amber, elektron, and, in fact, magnetism and electricity are simply manifestations of the same force. This concept of electric and magnetic interaction seems to have been established early in human history, though it would be almost 2,500 years before scientists came to a mature understanding of the relationship.

As in so much else, studies in electromagnetism made little progress from the time of the Romans to the late Renaissance, a span of nearly 1,500 years. Yet it is worth noting that the first ideas scientists had about studying Earth's history scientifically came from observing the planet's magnetic field. In the course of his work on that subject, the English astronomer Henry Gelli-brand (1597-1636) showed that the field has changed over time. This suggested that it would be possible to form hypotheses about the planet's past, even though humans had no direct information regarding the origins of Earth.

On the topic of global warming, I thought I would put this in. As you can see, the political system is corrupt and needs some reform. In Australia, this kind of manipulation and pressuring of sources is exactly the same.

"To support their charges Monday, the Democrats produced hundreds of pages of legal depositions, exhibits and e-mail exchanges between administration officials. The paper trail illustrated how officials with no scientific training shaped the administration's climate change message and edited global warming reports, inserting doubt in the place of definitive statements and diminishing the role people play in the planet's rising temperatures."

So what? What has this got to do with global warming? The earths magnetic poles have flipped lots of times (I learnt this at high school many decades ago).

It will happen again and cause havoc, but it is measurable and will not happen for many thousands of years.

Global warming is real, anyone who denies it is a fool. It may be caused by many reasons including human activity but it is happening.

Interestingly enough there is evidence appearing the sunspot activity may be one of the indicators of variations in solar output - very minor variations of same which have the potential to impact on Earth's climate. Sunspots are a magnetic phenomena, so it is probable that the solar magnetic field may incdicate climate variability more so than the local flip-flop.

I learned at school that poles do shift over time, hence the 5Degr.difference between True& Magn.North.
Co2 also seems to come "after" global warming, not the other way round as Al Gore pushed.

I think you will have to try and connect this poles flipping thing into global warming and tell us why you are right before we can make any purposeful posts here.
Global warming isnt a new thing, what people have to understand is that we never lived in a static world, there is always global warming or global cooling.
