true or hoax

Actually they can. They read the history books. For instance, in the early Roman Empire and the previous Repulican period, it was fairly warm until near the end of the Roman Empire where it grew colder and the barbarians could move their wagons over the ice. (Gibbons, the Fall of the Roman Empire) There was a period in the early middle ages where it became warm and then later on in the real middle ages, it became cooler (I do not know the exact century). That lasted on until past the 19th century and now we are seeing a warm period. By the way, that cold period from the middle ages lasted a few hundred years. The weather the next day can be predicted by individuals to some extent -the sky, but the weather report you hear on TV may be not from a local station so someone who lives in Ontario cannot predict the weather accurately in Manitoba because they are not close to the situation.

So very true, good point.

Good thoughts...I also believe if there is a global warming it is just part of an overall trend. The earth has been around a lot longer than we have and I'm sure it has survived much more drastic changes. With the advent of humans and their technology driven society the climate is taking a beating and we should consider taking care of mother earth better.

Exactly so, I do think we need to consider man made damage and try to correct some of it, but there is a lot that has to do with the planet itself.

I think you are absolutely right, the earth itself is on top of a chemical reaction right at the core and as a chemical reaction goes it will either cool or create heat and it is a natural occurance.

This is true but I think we are speeding it. A perfect example is the people visiting the glaciers. I don't know how many but I am sure it is in the hundreds visit in boats daily. I am sure all of those 98 degree heaters and the ship itself helps the glaciers melt. Heat melts ice. People need to think. If we stopped the tour boats to the north and south poles it will help. If this only saves days isn't it worth it?

I am sure we are causing changes and we need to do something about our extravagance. If we don't the price may be more than we can afford.

Natural cycles are the way the climate works. You have to have changes to balence things out.

Absolutely, extremists sure are overplaying their hand now. There is still the action vs reaction theory to think about as far as changing some of the manmade damage. But I don't feel the need to cry impending doom allover the world. But it does support the theory that man is his own worst enemy.

I agree. I think that it's a real issue to be concerned about, but I don't think it means anything like the end of the world, but it could cause some real problems.

There is definately some strange weather patterns, but I'm not sure I go with the global warming theory. I guess we have to wait till all the trees are counted on this one.

This is very true, but I fear that whatever steps we do manage to take towards reversing manmade damage may very well be a case of too little to late.

Absolutely there is some changes going on....I think we all need to make some changes to take better care of mother earth....we are have more worries besides global warming to attend to as well.

No doubt about that, we need to change our ways to save this planet from self destruction.

Hi hon, I wonder how many people will have to perish from the smog before it occurs to somebody that there is a problem.
