they also mentioned something about the earth having an irregular orbit which goes from a near circle (hot periods) and stretches to and oval (ice ages)...it said that we were in one of the more circular orbits right now.
it was some interesting stuff.
Dangit, sik-m, don't go muddying the issue with science and stuff. You're supposed to be alarmist. Don't you watch CBS?Quote:

Dangit, sik-m, if you don't stop being so reasonable, I don't know what we're gonna do with you. Balanced arguments about global warming are SO passe. You're supposed to be either in complete denial or be a chicken little alarmist. Do you see how the game works now? :icon_winkQuote:

You could make the argument that our world's average environment throughout it's long history has been one of warmer climate in which cold blooded animals ruled the day. I don't disagree with any of that.Quote:

The question is, are we speeding this process up to what our balance should or might be which is heavy CO2 environment, warmer planet, smaller ice caps, and unfavorable to warm blooded animals? That is the argument and always has been except for the ones on here who think that the climate is not changing at all and everything is fine.
Does the earth's orbit have anything to do with a changing climate? I haven't a clue. I am sure Stephen Hawking or another physics guy could elaborate on this further.
i would think that the orbit would have to effect the enviornment; if we are circling the sun more closely than logically we would get hotter...the closer to the fire the warmer you get. that being said, if rising co2 levels also drive up the earth's temp than we would be enhancing the warming that is already taking place as a result of the orbital change.Quote:

i do know that the carbon monoxide expelled by the hummers and excursions that cut me off in traffic is poisonous and a carcinogen (sp.)...so as much as i would like to roll down my windows while sitting in bumper to bumper traffic on the i-10, i don't because i wouldn't be able to breathe. this causes me to turn on my AC and use even more gas, releasing more toxic fumes. this wouldn't be a problem with claen-burning fuels.
in the grand sceme of things our pollution output may not have that great an impact on our enviornment...but it does have a profound impact on our bodies. ask the folks in mexico city or L.A. pollution is bad for you. the earth might be able to take it but it can kill us.
It just seems to me if the earth stretches as you stated, the velocity of the earth's rotation would have to speed up?
I pity anyone who has to live and breathe Houston air and toil in that traffic on a daily basis.
The tilt of the axis of the Earth as well as its orbit around the Sun certainly plays a role in the climate of the planet. About 12,000 years ago the planet started into one of its regular cycles of decreasing temperatures, normally lasting about 24,000 years. However, about 8000 years ago the temperatures stopped getting colder and started a gradual rise. The theory being that massive deforestation, rice cultivation, slash&burn agriculture plus raising livestock produced enough CO2 to stop the decrease in Earth's global temperature.
DogtorEvil, have you read the book?Quote:
