6 degress huh? got any sources for that number?

Here's a source that doesn't name a time frame but gives you an idea of where we are headed.

Quote: The new study, in the journal Nature, was done using the spare computing time of 95,000 people from 150 countries who downloaded from the internet the global climate model of the Met Office's Hadley Center for Climate Prediction and Research. The program, run as a screensaver, simulated what would happen if carbon dioxide levels in the atmosphere were double those of the 18th century, before the Industrial Revolution, the situation predicted by the middle of this century.


Here's a source that predicts the 6 degree change by 2100.

http://news.nationalgeographic.com/news/2005/03/0317_050317_warming_2.html

Quote: Under the worst-case scenario, by 2100 average temperatures are projected to rise by 6.3 degrees Fahrenheit (3.5 degrees Celsius) and sea level by at least 12 inches (30 centimeters).


Quote: If humans keep emitting greenhouse gases at present rates, the surface air temperatures could rise between 3.6 and 10.8 degrees Fahrenheit (2 and 6 degrees Celsius) by 2400, and sea levels may edge up at a rate of 9.8 inches (25 centimeters) per century

The NASA climatologist who originally adapted NASA's weather forecasting computer models to predict climate change "defied federal attempts to gag him" in regards to speaking out about global warming according to this month's national geographic.

People are STILL in denial too. Do some research on climate change, please. We must act to lower our CO2 emissions and most of all we must get over our state of denial.

Actually the increase was .6 degrees Celsius, while the predicted change was 1.8 degress Celsius. That is an overestimation of roughly 300 %. The fact is that no one can predict that far into the future. As for your claims of CO2 levels, why were the levels increasing in the 40's while the temperature was going down. Have you ever heard of aerosol sulfates changing the level of increase? That is something I read just recently. However, that is an un[proven theory as well. The fact of the matter is, there is no solid proof of global warming. There is no way to predict global change. Perhaps you should do a little more research on the topic.

James K Glassman. (2000, October 9). There is no evidence that the magnitude of global warming wil be extreme. Reason Online.

While I do not have a link, you should be able to find it with the above information. There are many more articles more recent, but this is the first one that I could think of. Basically, none of the fears surrounding global warming can be substantiated. Everything is based on theories that are unproven.

You need to read the article not the by-line. From your article Quote: Under the fixed-concentration scenario, the surface air temperature rise could exceed 1.8 degrees Fahrenheit (1 degree Celsius) by 2400, and sea levels may rise at a rate of 4 inches (10 centimeters) per century.

If humans keep emitting greenhouse gases at present rates, the surface air temperatures could rise between 3.6 and 10.8 degrees Fahrenheit (2 and 6 degrees Celsius) by 2400, and sea levels may edge up at a rate of 9.8 inches (25 centimeters) per century.


Let me put it to you this way, Yes the overall global temperature is increasing. It has increased by 1 degree C in the last 10 years. Every computer model seems to think it will continue to increase, which I agree with but no one is sure how much it will increase. An increase of 6 degrees in 100 years would result in the the poles melting at first, increasing sea level. However soon the poles would start to freeze along with teh areas close to the poles (Canada, Russia, Argentia, et al.) while the equatorial region starts to become arid.

However, the earth went through a "mini-ice age" from around 1500 to 1800 where the mean overall temperature was 2-3 degrees cooler that previous centuries. We have been coming out of that cool period for a couple hundred years.

I'm not sure what your refuting here. Yes there are natural changes in climate. That doesn't mean anything in regards to man's affect on climate. I read the article. I didn't quote the fixed concentration scenario because it is irrelevant. Were not going to stop adding to the problem anytime soon so there's no reason to look at a fixed concentration scenario.

Actually, the melting of most of the polar ice would NOT cause a rise is sea levels. Think of it this way, if you fill a glass up with water and put an ice cube in it, what happens when the ice cube melts? You see, the ice that is floating in the oceans now would not cause a rise in sea levels because they displace the same amount of water that they hold. However, if land ice melts, there may be a very large problem. Land ice, such as Kilimanjaro, has been melting for 6000 years. I guess that is caused by man also according to some.

Global warming is taking place, but it is not as severe as most make it out to be. The causes are natural, not man-made. The sun is the biggest cause of our current warming trend, just as it was responsible for our last cooling trend and the warming trend before that.

Refer to my thread on the subject of man made GW, you may be in for a shock. As for rising sea levels, look up the thermal expansion property of water. Guess what happens when water warms, *gasp* IT EXPANDS.

Actually, only at certain temperature ranges. Below 4C, water expands as it cools. Above 4 c, it expands as it heats.

The difference in density between water at 0c and 40c is minimal. Water at 0c has a density of 0.99984 kg/l. Water at 40c (104F) has a density of 0.99222 kg/l.

There are 1,260,000,000,000,000,000,000 liters of water in the world. For worst case scenario, let's assume all of that water is at 0C. If so, then the world has 1,259,798,400,000,000,000,000 kg of water. Now, let's see what the volume of that is at 40C (again, worst case scenario), it would be 1,269,676,483,038,035,919,453. The volume change goes up roughly 1.007 times. The high estimate for sea level rise due to thermal expansion is .4 meters. The low estimate is .1 meters. Neither is a catastrophic problem.

I am sure that all of the scientists, both those for and against global warming, do not know as much as you do about the situation. However, since their reports are published, I will continue to read them. Now, are you saying that you know more about the situation then they do?
