global warming

case sensitive said:
Are we (humans, pollution, etc) involved in global warming? yes.

Are we the sole cause? No.

Do we matter? In geologic time, very little. In global warming time, very much so.

Take a look at the dinosaurs. The earth they lived in was MUCH warmer than our earth. Who knows if the earth is just warming up to those temps again? There was an mini ice age in the 1300's. We could be warming up from that. Sure we're polluting more, and yes we need to stop these activites, but we are not the only cause by far. Actually the earth could be headed for another ice age. The increase of warmer ocean water, screws up the currents = heavy snowfalls = possible ice age.

Just my $0.02.

You make a number of good points here. I think most important is the fact that you understand man can effect the climate and that the effects are not always obvious. For instance when you state that an accute increase in temps could lead to a long-term cold period; good point.

But, why the hell would we want that to happen. Global warming is not about warmer weather, its about all the effects that change in climate would have on humans and the rest of life on earth. Frankly, I don't care of its summer 9 months a year or if its winter 9 months a year, it won;t be good for life on earth.

I'm sure if you allow yourself to remove the "who cares...I'll be okay" reasoning from your line of thinking, you will see that change probably will not be a benefit to your life, no matter what form it takes.

cow farts will be the end of us. i just hope im dead by then
The pollution one cow makes in a year equals the pollution one Range Rover makes in a day.

scientists have been saying global warming is happening for decades yet no one seems to care. so im wondering how many of you care and, in your opinion, how serious you think the issue is?
it's hard when so many people buy into the BS spin artists that say global warming is not real.. :bs:

I think it's one of those things that could be avoided but wont, and then we'll all just have to deal with it... sadly.

The "imagine if" statement in your previous post did not happen:

"imagine if man were created and lived its entire life during the last ice age, the environmentalists would have blamed the end of the ice age on pollution and man just because the environment changed from what it was previously"

Man has evolved and has lived for generations during a period of releative warmth. At the very least, humans that were alive towards the end of the last ice age lacked a language and societal framework advanced enought for taking scientific observations about climate. The "global warming" theory has not been developed in response to earth's climate coming out of an ice age.

the imagine if came from things like this that i posted previously which says, essentially, that earth has warmed up rather quickly in the past

National Geographic said:
The new study builds on research published last year. Studying sea level changes in corals and organic materials from Vietnam and Barbados, scientists concluded that an influx of freshwater from the Antarctic 14,000 years ago increased sea levels by an average of 66 feet (20 meters) over 200 years, about 100 times faster than today. There is evidence that debris was coming off the Antarctic as a result of the melting of the ice sheet.

so we have evidence that, in fact, something similar to what is happening now in terms of the earth's climate has occurred before and we have no idea what caused it. why is it not possible that something similar is happening again? had time shifted 14,000 years what happened at the end of the last ice age would be happening now, but it would be blamed on pollution. just because man is here now doesn't make it our fault. in the big picture, man isn't that important

it works both ways. you have to take into account the political aspects of being a proponent of stopping global warming when you read anything on the subject. being seen as caring about the environment wins votes and sells products. if you're careful with the info you collect you can make it say anything you want (just look at the fitness world. first it was carbs are good for you, then carbs don't matter just fat, then not fat just trans fat, then carbs are bad for you. all marketing). just because someone is a scientist and says something is true doesn't mean it is 100% based on hard factual evidence, but more than likely a finding that suggest something + political motivation (even scientists need funding)

Inexpensive nuclear power? Isn't that an "imagine if"?

Pretend SAT question:

Oranges are to nectarines as inexpensive nuclear power is to:

a) memo79 becoming a billionaire in the next 48 hours
b) cheap oil
c) quick pullout of US troops from Iraq
d) a 3rd gen Mazda Protege boosting 20psi daily on a stock bottom end
e) all of the above


lol, see avatar ;)

Sooo a 37% increase in atmospheric CO2 levels since the begining of industialization (c. 1800) is not because of man and won't have any side effect on temerature or life on earth. Got it. [Source of % increase: http://www.geology.iastate.edu/gccourse/chem/gases/gases_lecture_new.html]

Maybe temperatures are currently acting in the same cyclical way they have been for millenia, but CO2 is most defintely higher. What's the temp going to do? No one knows...

Those are some true to scale extrapolations. Bobby told me so.

The point I was trying to make did not involve me drawing abilities. The only item you need to take note of is the historical quantity of CO2 compared to current quantity. 375ppm is no joke and clearly indicates a change in atmospheric conditions. What this comparison fails to identify is the cause of the increase. I am not saying humans are the only cause, but does that mean we should ignore the change?

Freeze all the CO2 and shoot it into space.

I have 2 thoughts on the matter.

1st. there are a bajesus of educated and highly qualified, yet un political motivated scientists on each side of this. There are also alot of scientists that are VERY policitical modivated. But regardless, either groupd of these people know a WHOLE hell of alot more about this subject then I or anyone here can even pretend to. So until the scientific community has something even close to a firm conclusion...I wait. That said, acting on the side of caution just incase is not a bad thing. Afterall, I certainly don't want the sky over my home in rural NH looking like the sky in Los Angelos. So although I personly believe global warming is RADICLY over stated inthe press and highly fraudulent in its "facts" I see no point in ignoring its possibility and so I do my part to keep the grand kids cool. This is why I aviod arisol, I drive a failry effeicent car as opposed to an SUV and I am a religious recycler.

2nd: Can someone PLEASE explain to me how we are comparing carbon and other automosheric conditiaonl data from the 1700's when we had NOTHING that could accuratly measure the atmosphere back then? So in reason, we are reling on secondary data that can be highly flwaed from based on a number of elements that some scientist ignore, over state, or even rely on. Worse yet, it is VERY often political alliances that determin which one.

simple way that we collect methane from a long time ago when we obviously weren''t doing so because we couldn't, it's all in the ice. Take ice samples at different layers which can be identified and placed in a time scale and then do test cause air is trapped in there and measure the methane and nitrogen and other levels of gases in the air.
