Global Warming does not exist

[Berzerker]

If you saw a temperature graph for the last century, you might conclude humans are causing higher temperatures. But if you saw a temperature graph for the last 50,000 years, you'd see how wildly temperatures swing from warm to cold and back. The last century, in fact, the last few millenia, appear extremely stable compared to the last 50,000 years. And temperatures are not higher or anywhere close to what was reached over this period.
Taking "snapshots" of time is an illogical method for determining climate swings...

Global Warming also does not exist because:

Due to fossil records and geologic records- the ice caps have melted in the past and in fact, we are in a glacial ice age- they will regrow- they are merely melting because they are in a cycle.

Please notice: In the 19 00's and 20's many areas were excessively hot in the United States... Then in the 50's etc. record lows were set. Now record highs are again being set. It is a cycle.

I agree with Berzerker.

And as another note- as someone said the industrialists have a vested interest- so do the ecologists- the ecologists can gain more power and money for "save the whales" if their other ventures are "PROVEN" correct

Oh, which presidential commission- Clintons- if so, they could have likely been "selected" so that their prior prejudices showed through.

Also, what dates were they looking at- recent dates! Ha! The only ture way to measure global warming is to look at the whole picture.

Alynzia- how did they 'prove' this- by pollution records? And anyways- if they really did cause global warming- wouldn't the world be melted by now. :rofl:

Urban Ranger- it also causes warmer climates in colder regions and allows those areas to be better able to be farmed. They are not as arable, correct, but they can be made, and anyways if terraced farming is perfected, we won't need to worry much about the soils.

At the rate the tempurature is rising, that would mean that the ice age happened only a couple thousand or so years ago.

Actually its been like 10,000 years since the last Ice age.

Id like to see your calculations to prove what you just said.

and besides who said that the warming -cooling trend that the Earth goes through and is scientifically proven has to be a set number of years?

It's estimated that within the next century, global temperature will rise by ~1 degree celsius (and in the very worst case scenarios, even more - as much as 5)

And to show that it's climbing... During the twentieth century the global temperature raised 0.6 degress celsius, half of which was in the last 40 years, the artic ice pack also lost 40% of it's thickness in that 40 years. Seven of the ten hottest years in that century where in the 1990's. And, the global sea level rised about three times faster in that century compared to the rates of the previous 3000 years.

and besides who said that the warming -cooling trend that the Earth goes through and is scientifically proven has to be a set number of years?

Why don't you tell me? Since it's been scientificly proven, the process of it should be quite well understood.

I honestly have no idea what causes it.

[Evil_Eric_4]

All Im saying is that each Ice-age is not preset.
It just happens and there is no timetable.
We are currently between ice-ages and we still have not reached the cooling trend yet.

Looks like I called your bluff

"it just happens". Yup, that sure is a nice scientific explenation.

[Evil_Eric_4]

Dude go back to preschool

Allright Ill spell it out for you.

not all ice-ages last the same amount of years nor is there a set time between ice-ages.

So therefore you cannot count wild variations in the temps as our doing as we have only been keeping these records for a hundred years or so.

I think Ill turn this over to you as you are the one who needs to prove that it is us that is causing this so called "global warming".

History says that the earth on its own goes warm and cold so you need to prove to me that we are causing it.

NOBODY has proven it yet so I doubt you can.

[Ramo]

The thing about ecosystems is that their carbon dioxide absorbtion rates are accutely sensitive to changes in the climate, as well as changes in the carbon dioxide concentrations in the atmosphere. Basically, we're getting ourselves into a nasty feedback loop.

[General Ludd]

I don't deny that the earth's climate naturally changes, but as I said in that previous post - I honestly have no idea why it would go through "warming-cooling trends", and since you claimed to know scientific proof, I was expecting you to be able to tell me.

Look at my previous post - it's quite evident that global warming has signifigantly increased during the last 40-30 years of the 20th century.

And at the current rate - as I previosuly said - it is estimated that temperatures will rise 1(conservatite) to 5(extreme) degrees celsius in the next century.

[CyberGnu]

Also, what dates were they looking at- recent dates! Ha! The only ture way to measure global warming is to look at the whole picture.

So you are actually assuming that you understand this better than 12 of the countrys leading experts... Interesting. Pray tell, what other fields are you beyond mere experts in? Nuclear physics? Medieval literature?

Part of being educated is to understand your limits...

BTW, the commision was put together by Bush... He just refused to listen to them when their conclusions didn't agree with his (industrially bought) view...

And all Im saying is that no one has proved that this is not the natural course of nature.
Whos to say that bafore the last ice-age there wasnt a rapid increase in temps first?
were you there?
I think not.

As I said before it is the height of arrogance that we think we can change Earths climate.Maybe we are maybe we arent but like the existance of God you got to prove it to me first.

[CyberGnu]

Actually, people have already proven that there is better than a 90% chance that global warmng is caused by humans. It is not our fault you don't have the education to understand the proof.

The height of arrogance must be to assume that since you don't understand something, it must be false...

[Ramo]

And all Im saying is that no one has proved that this is not the natural course of nature.

First off, you can't prove a negative. Secondly, the greenhouse effect is a force of nature. It just happens to be a force of man, as well. Temperature changes have been strongly coorelated with changes in greenhouse gas concentration .

And there's no doubt that greenhouse gas production has been increasing in the past century.

It's not that simple. Large amounts of carbon dioxide is trapped in the permafrost now. Increasing the surface temperature will cause the permafrost to melt, thus releasing more greenhouse gases into the atmosphere. Right now the global climatic system is relatively stable, but once you tip it over there's no telling how far it will go.


Berz,

Not this wildly, not what's happening right now. The difference between now and the last ice age in terms of average global temperature is 5°C, and how long did it take to rise that much?
