Just to counter that. I recently read the above so heres the conclusion: Earth has been around millions of years, at one time it was a volcanic mess, so this is just one more era in a long history. I am not worried.

I'm sceptical too. For example the Mediterranean Sea has been empty and full at least 10 times in the earth's history. Sometimes we warm up, sometimes we cool down.

the snow drift in front of my house is 12 feet high !!

the earth formed 5 billion years ago from dust and rubble and then melted to a ball of magma from impacts and radiation from some types of rocks...

later it froze over for millions of years... during the early age of dinosaurs the atmosphere was saturated with CO2 that eventually lowered because of plankton over millions of years...

the earth will still be here until 5 billion years from now when it will be consumed by our sun as it ends it's life in a red giant.

over 90% of species that once existed on earth are now extinct !

there are at least 5 technologies in progress to extract and reuse CO2 from the atmosphere...

I would be more worried about nations run by talking monkeys that will eventually destroy us all with nuclear or bacteriological weapons...

everyone acts like they're an expert. nobody knows why changes are occurring but they are and always have. all we can do is make observations of the climate change. no theory has been right thus far.

This article is just what I read and yes the earth does goes through changes. About 600 million years ago the earth suffered a deep freeze and some believe it was the year of the Snowball effect which was at one time difficult research they had to proof to most of the scientist. For awhile that theory was finally solid and approved by many until more evident disapproved the theory of the snowball effect on earth. Either way there was for sure an ice age that most believe could have changed the course of evolution.

Here is the link which now has put the theory in the cold.

To extend in what Nick is saying about our sun...
A low mass star like our sun exhausts itself of hydrogen inside the core, no longer will it have any source of heat to pretty much support the core against gravity. Now the hydrogen continues to burn like a shell around its core and the star evolves into a red huge giant sun or star. Once the sun becomes a huge red giant, the atmosphere will overwhelm the earth and our planet will be consumed in flames.

Meanwhile, the center of the sun, which is the core, will collapse under gravity’s pull until it reaches at a high enough density to start burning helium to carbon. The helium burning phase will last about 100 million years I believe, until the helium is exhausted in the core and the star becomes a red super-giant. At this stage, the Sun will have an outer cover extending out towards Jupiter. During this brief phase of its existence, which lasts only a few tens of thousands of years, the Sun will lose mass in a powerful wind. Eventually, the Sun will lose all of the mass in its covering and leaving behind a hot core of carbon embedded in a nebula of expelled gas. Radiation from this hot core will ionize the nebula, producing a striking "planetary nebula", much like the nebulae seen around the remnants of other stars. The carbon core will eventually cool and become a white dwarf, the dense dim, what was once our bright sun.

To get back to the subject.
We know for sure that it’s melting rapidly and it only gives us some important information base on what we been observing which can provide more answers and possibly solutions. Some countries are going to do away with Oil by the year 2020 and more, and I notice the European countries are on the ball and making a difference.

we can never be 100% sure...

but reading respectable scientific works by renowned authors is better than believing e-mail chains :P

Sas... I was just watching Carl Sagan's Cosmos series part 9 ''the lives of stars''
where they illustrate the 3 different types of star finales... great stuff !seen it ?

yes, but the scientists themselves know barely anything about the sun's cycles or what really is in the center of the earth. how does a planet sustain a magnetic field for 4.6 billion years? something's rotating down there and thats the best we can figure out. however, the magnetic field has gotten 50% weaker in the past hundred years and is weakening exponentially, combined with the solar storms being at their maximum in 2012 will cause a whole lotta things falling from low earth orbit like satellites and planes if the magentic field gets weak enough. however, research has told us that the magnetic fields weaken to when theres practically nothing left and then do a reversable and become strong once again, good for thousands and thousands of years.

global warming and global cooling are the wrong focus. the focus should be on what we are going ot do when our magnetic field is going ot screw up the billions of animals' migratory paths and all our high tech equipment. using zero point energy is a ****ing given but theres greedy people whose god is money and power from the money so they keep innovations like that away from the serfs to conitnue their matrix of power.

anywho, things wil be better, theres not much to worry about. yea, we're livinjg in a very very dark time in history but it will soon come to pass, much to the disapointment of blood thirsty christian fundamentalists who have been salivating over the notion of an armageddon for hundreds of years now.

I saw a show on tv the other night and they were saying the South Pole has been getting colder.
:D

The question is how do we know or how does Earth gets magnetic field? It’s not a simple answer. But it does seem clear that the generation of the magnetic field is linked to the rotation of the earth, since Venus with a similar iron-core composition but at 243 Earth days rotation period does not have a measureable magnetic field. Scientific Theory is based on facts and inference and until now it demonstrates the central organizing principle of what we can understand in science.

Carl Sagan has often quoted as saying, “Extraordinary claims require extraordinary evidence.”

What did he really mean?

Well, because scientist is fallible humans, errors in observation or logical inference can be made, but since, however is a self-correcting process.
It’s seems plausible that it depends upon the rotation of the fluid metallic iron, which makes up a large portion of the interior and the rotation conductor leads to the term dynamo or geodynamo effect.

One day we will probably change our theories to a more plausible understanding or just maybe add more to the subject in hand. The main purpose is that Science is the central principle of theory base on inference and it is all what we have to offer compare to mambo jumbo we hear or read that are out there and making false statements that have no logic and have people actually believe in silly phenomenal rubbish crap.

I watch them all Nick it's still great to watch it over and over again.

Btw Nick did you see on Science channel the Snowball Effect?
It's an excellent theory but lately it has been out in the cold again.

nope didnt see it...

but this is not one of my favorite epocs as nothing really interesting happened except the actual snowball...(if it did indeed I see)

A couple of thoughts:

First, it's not about the fact that the Earth is warming. It's the RATE of the warming that is alarming to most scientists. We are seeing a rapid and fundamental change in average temps unlike anything in Earth's history. THAT is the cause for concern, and the fact that all that melted water is going to make Miami look like Atlantis in about 50 years...

Also, the weakening of the Earth's magnetic field has happened over and over for many millions of years. There is a record of it in the basalt rocks that form in the Mid-Atlantic ridge and move towards the continents. It hasn't caused mass extinctions or other Hollywood fanstasies so stop worrying about it. The impact to our technology is the greatest concern but life will go on...
