have you watched Al Gores movie?
ya, whats your point?
i also believed every word he said because i didnt doubt the gov't credibility. like i said, the more i have been researching the more i see the corruption and brainwashing that is taking place.
in the last link that i gave you i asked you to look at his graph that he presents... the one with co2 vs temps, did you look at that? if you pause the video on his graph, you(well at least i can see) can actually see that temp precedes co2... this is his graph mind you.... please take a look and tell me your thoughts.
did you try the ice experiment?
another way to think about how the ocean absorbs co2 when its colder.. if you have studied a little bit about hydroponics you are versed with the term DO(dissolved oxygen). to increase DO you want your res temps to be ~60F or so. the hotter your res is the less DO available for your roots.
let me find a link to demonstrate this.
The assumption is that, over time, the concentrations of the various atmospheric gasses are LOCKED when the air bubble is "trapped" in ice. And therefore, as long as you can determine WHEN the air bubble was trapped, you can measure the concentration of CO2 therein and state, with confidence, that the atmosphere itself had that same concentration at the time the air bubble was trapped.
But the assumption is wrong! It is a well-known fact that liquid water absorbs carbon dioxide.
It is also a well-known fact that carbon dioxide is more soluble in cold water than in warm water. In fact, solubility increases geometrically as temperatures decrease.
A much lesser known (but nonetheless true) fact is that ice, though composed mainly of SOLID water, does still have some molecules that are in a liquid state. Whether a given molecule is in a solid or liquid (or even gaseous) state, at a given time, depends on how much energy that molecule has at that time. The energy of individual molecules can vary greatly from moment to moment, due to any of various physical events going on in the substance. Now, when water is "solid", the vast majority of these molecules, at any given time, will not have enough energy to be in the liquid state. But SOME of them will. And those that are liquid will absorb a great deal of carbon dioxide, even more than they can absorb at the freezing point.
Another much lesser known (but equally true) fact is that, at low temperatures, among the three main components of the atmosphere, carbon dioxide is seventy (70) times more soluble than nitrogen and thirty (30) times more soluble than oxygen. This means that, when an air bubble is trapped in ice, not only does the liquid in the ice continue to absorb gasses,
it does so SELECTIVELY, favoring carbon dioxide, by a huge margin, over the other common gasses in the air bubble. Of course, every molecule of carbon dioxide that passes into a solution is REMOVED from the air within the air bubble. And therefore, since more carbon dioxide is removed, less carbon dioxide will appear in the remaining air. And therefore, after thousands, or millions, of years, when that air bubble is tapped, and the gasses within it measured, the concentrations of the various gasses can no longer said to be the same as when that air bubble was trapped, all those years ago.
It should be noted that there are OTHER proxies for determining historic carbon dioxide levels in the atmosphere. Density of stomata on leaves, for example, has been found to be highly correlated with carbon dioxide levels. Paleobotanists can take fossilized leaves and count the number of stomata, and, from that, get a fairly good picture of how much carbon dioxide was in the atmosphere at the time the leaves died. Carbon dating can determine how long ago that was. Interestingly, using fossilized leaf stomata to determine
carbon dioxide levels yields much more variable estimates than air bubbles, which showed relatively stable CO2 levels of between 260 and 270 ppmv (parts per million, volume) over the last 10,000 years.
So, the answer is that air bubbles in ice core samples are not realiable for determining historic levels of carbon dioxide in the atmosphere. The implications for this fact on the theory of anthropogenic global warming are devastating.

so the fact that colder ocean temps absorb more co2 is evident in this wiki quote. what dont you ppl understand that temps mainly effect co2 levels and not the other way around?
our current co2 concentrations is ~300 ppm(if you live in a city im sure its a little more) so over the last 10k years our co2 levels have only gone up ~30 ppm.
the ocean is big and it takes a long time for its body to change temps, but once this does happen the co2 levels change accordingly-thus the 800 year lag..
maybe you guys should study about the sun and learn about sun spots and how it goes through hotter and colder cycles.
lol, maybe i should right a book... maybe my RIU name takes away some credibility, who wants to be schooled by a person who names himself wetarded
