Looking for Scientific basis on Global Warming

I'm not interested in having a debate about global warming, or CO2 emissions or anything like that. I just wanted to know if anyone here is in the scientific community or has an inherent knowledge into the subject of economic projections.

I'm wondering about the probability or function that is used for the negative-feedback reaction of a warmer earth causing increased precipitation which causes increased cloud cover which causes cooling of the earth, and also about the idea that we're due for the next ice age, which coincides with increased temperatures before it hits.

Again, not a debate, just looking for some more information, since we had a discussion/lecture about it in class tonight (Natural Resource, Energy, and Environment economics). If you're worried it'll spark debate, then feel free to PM or email me.

Thank you and I'm very appreciative of any (positive) feedback or suggestions :)
 
This outta be good...

Do me a favor if you get any info via pm shoot it over to me. I like seeing all sides as well.
 
Again, it's not a debate. While I do believe in global warming, and believe that science will prove down the line that it is real, and it is really a danger, I feel that I have a better perspective on the world if I play devil's advocate as to gain a better understanding overall of a subject. Regardless there are a lot of things that are just impossible to take into consideration with global warming (like technological progress) so I'm just wondering what some of the other considerations are modeled on (the negative feedback mechanism and ice age stuff).
 
If/when the iceage comes, it'll be no chillers, but your nice waterfront house will be overlooking a giant cliff of dead coral and stinky dead seaweed. At least you'll still be in one of the arguably warmest climates :p
 
From all I have read, the global worming due to Co2 is a mith. The fact is an Ice age happens every 11000 years and is unavoidable, due to the earths axis.
 
Steve, I really would love to discuss it further, but unfortunately here isn't the place for it, as we'll get in trouble. I'm on AIM if you'd like to discuss it and some perspectives on it, but again, to my knowledge, we cannot have that discussion here.
 
Maybe a mod can step in and let us know. Global Warming would affect the reefs of the world and indeed this hobby. After all one of the things I enjoy about the hobby is that people who see my tank gain a new respect for the wild coral reef and the earth itself. I don't think there is really any problem discussing this here.

MODS Can we discuss Global Warming?
 
Google NASA earth photos data may get something there, problem with all data is its has only been recorded since the 50's best evidence comes from ice core samples taken in the south pole which is more pristine in its samples than the north pole
 
Of course it does effect us in the hobby, and we realize it's impact further than most people around us. The good thing about aquaculture is that if we humans can afford to keep aquaculturing alive, at least we will preserve some of the corals on the reef. To be fair, they'll adapt as well to the increased temperatures, increased water depth, etc just as they have through the last millenia or more. That's why they're still around, adaptation. I'm specifically avoiding using certain "debatable" words because that's where the mods step in, when a debate about topics like it comes up. That's why I said no debate.

The NASA photos are great, but we don't have them over a long period of time, so it's not really a great indicator. You mentioned the CO2 recordings (Keeling curve/Keeling observations) which though yes, they show a steady increase since they were first taken in Hawaii in the 50s or 60s, again, they're not good enough long term evidence. There were mini ice ages in the 1800s and 1900s that we didn't quite know why they happened, how they happened, and don't have measurements before and after they happened either, we just know that it was abnormally cold and we had crop problems from it.

The ice core samples are very important as well for measuring CO2 and snow levels over time, but I kinda forget off the top of my head the information I learned about them. I do know that they show cyclical increases and decreases in snow cover and CO2 in the atmosphere, as well as some other oddities (like meteorotic material) that we can't quite explain, but I'm sure with future knowledge will be significant towards the understanding of the early earth (again, another topic that can be discussed and debated, but should be avoided).

I think the reason that we cannot discuss these things is that A. They're not primarily reef based, B. Religion can be used as an argument against all of what I've stated before, and C. Politics can be brought into the discussion as well. All of those reasons are why we cannot have a debate about the topic.
 
I don't believe those are good enough reasons to not have a discussion. Probably not good material for a first date though.
