That is my opinion. Now lets keeps this a strictly scientific discussion. No politics here please.

Would someone please present me with some Valid information from a reputible source that supports man as the cause of global warming?

So far this hypothesis of Man made Global warming does not stand up to scientific scrutiny. The hypothesis is this: "Global temperatures will rise significantly, perhaps catastrophically, if atmosphere carbon dioxide rises." Most of the increase in atmospheric carbon dioxide has occured during the past 50 years, and the increase has continued during the past 20 years.
Yet there has been no significant increase in atmospheric temperature during those 50 years, and during the last 20 years with the highest carbon dioxide levels, temperatures have decreased. Evidence points to fluctuations in warming due to Solar activity (solar cycles) and not to any increases in Carbon Dioxide.

The facts: The earth went through a "mini ice age" 300 hundred years ago. The earth has slowly been warming, from that low, ever since. during the last 3 thousand years there have been 5 extended periods when it was distinctly warmer than today. Today the average atmospheric temp is below the average temp for the past three thousand years.

And if anyone can point me to a weather man that can accurately predict the weather farther out then three days in advance with any regularity then I will listen to him. But otherwise Man knows so little about how weather behaves and why that predicting it for the next 50 years, let alone a week in advance is completely unreliable.

 

I agree with you. We are WAY too self-important when it comes to this planet. We think that everything we do has a dramatic impact, and I just don't see it. The planet is getting warmer, but I doubt it has anything to do with us.

I'm always prepared to be wrong, and I'd like to see what kind of evidence people can provide.

Here...its been reconstructed many many many times....its a cycle. The earth, environmental, and universal changes have more effect on temperature and climate than man. Man only wishes he could cause global warming. Unfortunately, we cannot escape the politics of it. Just wait a thousand years or so and the tree huggers will be screaming about man causing global coolin. NOOOOOOOO!!!!

 

When confronted with a question about Industrial & Vehicle emissions vs volcanic eruptions & Forest fires and the amount of what each one is spewing into the atmosphere causing Carbon Dioxide any Green Peace or activist blowing smoke out their butt about Kyoto, usually just shuts up or avoids the topic.
All they want to do is spew rhetoric about vehicle because It keeps the money rolling in.

We have activists in Canada and when they say that Canada should be part of the Kyoto agreement they don't realize it is futile and does nothing but cost us money.

This is how I apporach it with them.

Q: " So,you want to be part of Kyoto"

A: Yes,

Reply: Great , do you know what it means ?

A: Yes, It means countries should lower carbon dioxide emssions to make things better.

Reply: actually NO it doesn't.It measn that Rich countries like Canada can give money to other Dirty Countries to by credits for making smoke.

Let me use this an an example:

You be Canada and I'll be China.

Now, You give me $10 Billion dollars and I'll go set a huge pile of tires on Fire and let it burn for 5 years.

Thanks for your money,I'll be back for more

Right now I have to be some other Dirty country so I can get some fairly clean industrialized country as Dumb as you to give me money.


At this point I tell them if you want the Kyoto agreement then YOU pay for it out of your OWN money.

Until then consoder the fact that the earth is this huge un-stable sphere flying through space and it goes through cycles in certain areas of the globe.
ie: Earthquakes,Volcanic eruptions,etc

So, If you don't like the ride...get off...there is nothing any Human can do about it

 

One thing the tree huggers forget is the earth was a greenhouse early in its life.

Mother nature straighten everything out. It's just a cycle.

I read a news article today that said one of the polar regions was tropical a long time ago.

 

One source I read had human contribution to CO2 levels increasing at 1 to 3 percent. Seems pretty ineffective to address the 3% of the problem and leave the other 97% alone.

BTW, do you realize that water vapor is also considered a greenhouse gas. Think about that, those of you pushing for a hydrogen economy.

 

You mean passing gas doesn't cause global warming?

That's great.

Now I can go back on my beer and hard boiled egg diet.

 

We have enjoyed ~75 years of relatively stable weather here on Earth recently which is definitely not the norm according to tree ring patterns. Floods, drought, storms, destruction, famine and feast are the norms for this planet. Get used to it...

 

i don't know, but its a little too serious to be wrong about it.

i am all for pollution controls, smart ones i must add, it is just common sense, millions of cars, factories and such pumping pollution into the air, it has to have some kind of effect somehow at some time. but it would suck to learn the results when its to late to change anything.

kind of like all those early nuclear tests "oops! it IS dangerous! sorry everyone!"

 

bf250,
Perhaps your position is prudent when it comes to the environment. After all it is better to be safe then sorry, correct? but has much thought been given to what excess CO2 in the atmosphere may cause in terms of benefits to life on this planet?
Increases in CO2 benefit what part of the planet? Plants.
standing timber in the US has increased 30% since 1950. Atmospheric CO2 accelerate growth rates of plants and permit plants to grow in drier regions. Animal life, which depend upon plants also increase. The planet in effect becomes more lush. More plants globally means more food, more food means great capacity to reduce starvation. Is that such a bad thing?

 

"Would someone please present me with some Valid information from a reputible source that supports man as the cause of global warming?"

Here's one:

http://www.sciencemag.org/cgi/conten.../290/5499/2133

If you can understand this one, there's hundreds more that are much more complicated.

Can't vouch for them as a reputable source, but most scientist would give their right arm to publish in Science Magazine

 

According to scientists, the Earth is getting warmer in recent years. Also according to scientists, the polar ice caps on Mars have been shrinking, too. They say that this is caused by an increase in solar radiation. Perhaps the warmer conditions on Earth just might be caused by the same thing that's causing warmer conditions elsewhere in the solar system? Don't get me wrong; I think man is doing a great job of fouling the atmosphere, but I don't believe the seas are going to rise 20' any time soon (sorry, Mr. Gore).

 

I want to point out that changes in climate aren't really the same as weather. Weather fluctuates very rapidly, but changes in climate are very very slow. It's not really fair to bring the accuracy of weathermen into this debate. In a way, it's easier to predict the climate 100 years from now than it is to predict the weather next week, since it's all based on statistics.

Climatologists (I think that's the word) need hundreds of years of data to be able to make any kind of predicitons. Any of you who have taken any statistics classes will know that we are talking about variations in the mean, not variations about the mean.

Dennis, I'm with you. Kyoto is not the kind of measured and reasonable approach to this problem that this planet needs.

One of the world's best renewable resources, trees, are totally ignored. The ones we do not have to renew, solar, wind, and thermal are not even a blip. I do think sooner or later, at least for urban drivers, electric will be the way for vehicles.

If the USA and Canada really want to do something, they will produce and promote cars that do not use oil for its power plants.

Wrong .....especially for Alberta and BC.

Maybe do some research before making a statement like that ?

We have re-forestation programs in place.
Every summer students are hired to plant tress in de-forested areas.
