i dont beleive in global warming because i think that it is so gradual that by the time it is dangerous the next ice age will counter act it

Does any one else have any views or opinions about that?

Goooo ocean!

Ok, I'm going to pretend like Carlie is right (I don't think she is)


Although a forum is a place for the free exchange of ideas, thus I would normally not bring up somebody's credentials or qualifications, in this case I would like to point out that this is at least in part Carlie's area of expertise, which is considerable given her level of study.

This means two things:

1) I trust what Carlie says on the subject (you still don't have to).
2) If you wish to refute what Carlie says you ought to quote material of an academically rigorous nature (more important).

Well, the other question is whether and how much this equilibrium can be expected to change over what timeframe.

The earth has carbon sinks (plants, soils, deep sea sediments, etc.)


I think I'm correct in saying that snow too, is good at absorbing carbon dioxide. So the effect of melting the icecaps is also putting this stored CO2 back into the air and then trapping more sunlight.

Ok, I'm going to pretend like Carlie is right (I don't think she is) and say that there is direct correlation between CO2 and temp.


I don't get how people can just say things like that without backing it up with empirical data. You should at least state why you feel there is no correlation.

Yep, which the graph I put on the last page addresses pretty well I think:
http://ryanthibodaux.greenoptions.com/files/images/co2Temperature.gif
There is definitely a lot of variation in atmospheric CO2 over time. We are constantly going through glaciations and deglaciations, and experience variability in temperature and atmospheric gases. However, it is also true that in all of geologic history, the earth has never naturally or anthropogenically experienced these high levels of CO2. Naturally, CO2 has never tipped 280ppm, while we have pushed it up to 380ppm and continue pushing it farther.

and say that there is direct correlation between CO2 and temp.

Also, I specifically stated that there was not a direct correlation, but an indirect correlation, as I stated on the previous page.

For those of you that don't know, CO2 is that stuff that lets trees breath and live thus let us live, but anyways..

You're right, CO2 is very important. We could not live without it, a certain level of CO2 is integral to life on earth. But we are pushing it over its limits, which is where the problem lies.

And it's also important to point out that there are two types of equilibrium, stable and unstable. A stable equilibrium will return to the same equilibrium if pushed off balance. Unstable equilibrium will tend to fall to an equilibrium with a lower energy state for the system. We don't want to push the environment too hard for too long or this will happen, then the result may well be a situation that can't support human life.

Don't forget the power of HEART! I remember that from Nostalgia Critic's review of the show
-----------
CO2 is important, but almost anything can be detrimental if not in the correct amounts.
--------
Naturally, CO2 has never tipped 280ppm, while we have pushed it up to 380ppm and continue pushing it farther.


. . .Which proves that global warming is NOT a myth created by the treehugging, arugula salad-nomming uberliberals of San Francisco. . ..(I think they're myths, as that's a crazy stereotype. But that's offtopic.)

WELL, on that topic... If we do continue to push this to its limits, global climate change does have a pretty good chance of disrupting the great ocean conveyor belt. Meaning the circulations that drive the climates and weather of all of earth. Have you ever seen The Day After Tomorrow? It is basically like that. Weather will become increasingly sever, climates will be pressed to the extreme, glaciers will advance... etc. Except that in reality if this happens, it will happen on a slower scale, and not over the course of a couple of days as it does in the movie ;-)

But the movie was actually based on the very real possibility of that sort of environmental collapse occurring.

I saw a show that said that the plants living at the north and south poles don't decompose due to the freezing temperatures and the hard permafrost, so when they die, they just compact and become carbon. So if the poles melt and all that carbon is released into the atmosphere at once...*Shudders and buys an electric car*

global warming is not real it is a cycle of the sun

Necro! I know it's not your fault, but click on the section sometimes.

Global warming is a way too make more money. It's actually being caused by a freeze thaw cycle. We've been warming up since the last ice age and sooner or later we're going to start cooling off.

Global warning exists and there are many proves of that:
1)The Global surface temperature increased by 0.74 C

2)Results recently published in the journal Global Change Biology show a population drop of 60% in worldwide caribou and reindeer numbers over the last three decades.

3)Melting glaciers

4)Rising sea levels

5)Erratic weather patterns

Here are some of the factors that have contributed to global warming:
1) The burning of coal and petroleum products which contain carbon dioxide, methane, nitrous oxide, and ozone. These gases add to the thermal blanket which protects our earth. This increases the amount of greenhouse gases in the atmosphere, which in turn, traps more heat and increases global temperatures, making a process that was natural and beneficial, now potentially harmful to life on earth.

2) The amount of deforestation in the world contributes to global warming since it increases the amount of carbon dioxide in the atmosphere, and reduces the amount of oxygen we can breathe. Increased cattle production is another factor, as it has also contributed to deforestation.

3) Methane gas which is released from animal feces can enhance the thermal blanket.

4) Methane production and the use of fossil fuels create greenhouse gases which augment the thermal blanket as well.

Most of your theory just went down the toilet. Proof-

http://www.theregister.co.uk/2008/08/15/goddard_arctic_ice_mystery/

People are so gullible. The media love to lie.

Anyway, I can prove most of your facts wrong without the article anyways

The Global surface temperature increased by 0.74 C


That's only like 2 degrees Fahrenheit.

Results recently published in the journal Global Change

Biology show a population drop of 60% in worldwide caribou and reindeer numbers over the last three decades.


They are being hunted.

3)Melting glaciers
4)Rising sea levels


If the sea levels were rising, inland states in the US would have a whole hell of a lot of refugees right now.

Erratic weather patterns


Ugh, when our parents were about 12/13, it was like this too.

No it's not 0,78 Celsius = 33,4 Fahrenheit

Those thing don't happen so quickly, but until 2050 you are going to see it happen.

Erratic weather patterns

Instabilities in oceanic thermoclines - cyclical thermal patterns in the water column - and disruptions to these patterns and their flow will inevitably cause erratic weather patterns and chain reactions that affect different parts of the globe. Ocean thermoclines are affected by a series of factors including pressure gradients directly above the ocean surface, currents, and deep ocean conditions. Water is cooled and heated by surface and subsurface conditions and as a result flows deeper or rises higher in the water column. Currents and convection divert different temperatures of water to adjacent areas which in turn affect the atmospheric conditions directly above, and hence there is a chain reaction. A disruption in the atmosphere, such as a hole in the ozone, affects the whole atmosphere-water column and then disrupts the balance of thermocline patterns. Global warming produces higher sub-surface oceanic temperatures, also disrupting the natural cycles of ocean thermoclines. Drastic, unstable pressure gradients result from all this and may produce devastating storms, giving rise to events such as El Nino.
