They can't predict the weather for next month...But they know for damn sure what will happen in the next 50 years?
This was a great thread, I am really happy that the discussion stayed level headed, no name calling or anything! Awesome!! :hippy:
I'm sure that man has some effect but not as much as what the Al Gores want us to believe. When I watch the nightly weather report and see that the high temps were from the 1930's and the lows from the 50's it's pretty clear. There are cycles.......just to bad that some fat cats use this to line their pockets.
Have a good one!:s4:
dont cows create just as much co2 farting as cars do?
true?
i voted bullshit btw as global warming has happend before, way before humans
and global cooling
i do think we are adding to the problem thus speeding the process up

Carbon dioxide in earth's atmosphere is considered a trace gas currently occurring at an average concentration of about 385 parts per million by volume or 582 parts per million by mass. The mass of the Earth atmosphere is 5.14Ã?1018 kg [14], so the total mass of atmospheric carbon dioxide is 3.0Ã?1015 kg (3,000 gigatonnes). Its concentration varies seasonally (see graph at right) and also considerably on a regional basis: in urban areas it is generally higher and indoors it can reach 10 times the background atmospheric concentration.
Carbon dioxide is a greenhouse gas; see greenhouse effect for more.
Due to human activities such as the combustion of fossil fuels and deforestation, the concentration of atmospheric carbon dioxide has increased by about 35% since the beginning of the age of industrialization.[15] In 1999, 2,244,804,000 metric tons of CO2 were produced in the U.S. as a result of electric energy generation. This is an output rate of 0.6083 kg (1.341 pounds) per kWh.[16]
Five hundred million years ago carbon dioxide was 20 times more prevalent than today, decreasing to 4-5 times during the Jurassic period and then maintained a slow decline until the industrial revolution.[17]
Up to 40% of the gas emitted by some volcanoes during subaerial volcanic eruptions is carbon dioxide.[18] According to the best estimates, volcanoes release about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere each year. Carbon dioxide is also produced by hot springs such as those at the Bossoleto site near Rapolano Terme in Tuscany, Italy. Here, in a bowl-shaped depression of about 100 m diameter, local concentrations of CO2 rise to above 75% overnight, sufficient to kill insects and small animals, but warm rapidly when sunlit and disperse by convection during the day[19] Locally high concentrations of CO2, produced by disturbance of deep lake water saturated with CO2 are thought to have caused 37 fatalities at Lake Monoun, Cameroon in 1984 and 1700 casualties at Lake Nyos, Cameroon in 1986[20]. However, emissions of CO2 by human activities are currently more than 130 times greater than the quantity emitted by volcanoes, amounting to about 27 billion tonnes per year (30 billion tons).[21]

Mother nature creates...and mother nature will take her own bath eventually. We can assist the clean-up process but saying that man is the cause is ridiculous.
Have a good one!:s4:
It does not matter [B]exactly how much man is contributing to the problem. [/B]
The point is, our mother earth is dying and heating up quickly. We have the moral responsibility to ourselves, our home, and our children and grandchildren to at least attempt to slow down the process so perhaps the human race can survive a little while longer?

Ha ha! Funny, but not true. Cow farts do not produce as much CO2 as cars.Quote:

The CO2 levels stay relatively constant because the natural carbon cycle is in balance, exchanging carbon into the air and reabsorbing it back into living things. The difference with cars is that the fossil fuels that are burned by cars are not part of the carbon cycle. That carbon was taken out of the atmosphere hundreds of millions of years ago and stored under ground in the form of oil and coal. When we mine the fossil fuels from underground and burn them, the carbon released into the atmosphere overwhelms the carbon cycle. There is no natural mechanism to get that carbon out of the atmosphere at the same rate that we put it in, so the amount of CO2 in the atmosphere increases.
There are actually a lot of people who believe what you are saying here, and they live their lives as much as possible like you describe.Quote:

There are sources of electricity that do not come from fossil fuels. Where possible, it is best to use those sources rather than the fossil fuel sources.
And, yes, using a 350 hp gas engine to move a 180 lbs, is not very fucking efficent! We all love our cars, but it might be better not to get the 350 hp motor unless you NEED that kind of power. There are much more efficient cars coming out all the time. And there are automotive fuels that are not fossil fuels --- fuels that ARE part of the natural carbon cycle. Bio-fuels that are made from plant and animal products do not pull carbon from underground and put it up in the air. They use carbon that is already in the cycle.
I'm not sure how you make that conclusion based on the article you quoted.Quote:

How is that natural? Man is the cause.
The most important thing in the article is the background info about how five hundred million years ago carbon dioxide was more prevalent than today and continuously decreased over time until the industrial revolution. That was the period in which the coal and oil we burn today was formed. We are reversing five hundred million years of natural processes in about 100 years. That's going to shock the shit out of the system.
Carbon dioxide is not the major greenhouse gas, water vapor is.
Carbon dioxide accounts for less than ten percent of the greenhouse effect, as carbon dioxide's ability to absorb heat is quite limited.
Only about 0.03 percent of the Earth's atmosphere consists of carbon dioxide (nitrogen, oxygen, and argon constitute about 78 percent, 20 percent, and 0.93 percent of the atmosphere, respectively).
Most of the carbon dioxide in the atmosphere does not come from the burning of fossil fuels. Only about 14 percent of it does.
Most of 20th Century global warming occurred in the first few decades of that century, before the widespread burning of fossil fuels (and before 82 percent of the increase in atmospheric CO2 observed in the 20th Century).

I disagree, there are ALOT of people that believe we are destroying the world and causing global warming, there are not ALOT of people that live their lives in a way that is consistant with their beliefs.Quote:

There aren't any easy answers for sure, and I believe that we should be looking for the next best thing, and that we should always strive to be better. I loath the fact that people would try to tell me the world is going to end due to mankinds use of fossil fuels, I just personally believe it is rubbish. Again, it makes me suspicious when people or groups rely on this kind o a tactic to prop up their argument instead of facts. I am not directing that at you Dragon at all, I am referring to the news media and politicians. I know you believe what you are saying, and respect you for standing by your beliefs, I just happen to believe that you are wrong. I would still burn one with you, in an environmentally friendly way of course!:D
