Climate Policy

First this is done using modeling. And starting with CO2 concentrations in ice. When using the antarctic ice values the CO2 concentrations went up at the same time the temperature went up. If however also using the ice values of Greenland it seem there is a lag of around a 1000 years.

Going out into the arctic and antarctic to gather evidence is hardly modeling. Perhaps, one might argue with the lines the deduced from the evidence. Another question then is that temperatures begin to cool, while CO2 levels remain high. Then after cooling, CO2 levels begin to drop naturally with cooling. Again, we are talking about the natural ebb and flow of temperature changes without human interference. I'm not sure we can be *certain* yet what effect we are having on the climate. But, as I've said before, I'm an advocate for ecological purity (leave no footprints).

First, I find 1 or 2 measurements both a bit little for these conclusions. Also when in their conclusions they authors only talk about the temperature of the antarctic oceans. Further, you are correct to state that a conclusions that heating uo will increase CO2 concentrations doesn't mean that the first heating up was cause by higher CO2 concentrations in the first place.

I would guess that other peoples peer reviewed analysis of their methodology would disclose defects. Multiple ice cores from northern and southern latitudes would trap thousands of years of climate information in the ice. I would guess then that taking multiple samples would corroborate that a single sample did not have a unique defect, so that multiple samples would show the same trend over a large geography.

2nd I think we can discard the concern some forum members had that scientists that go against the CO2 theory are not allowed to publish.

It doesn't go against the anthropomorphic CO2 theory, but it does show that rising temperatures may result in a naturally higher CO2 level. It also shows that CO2 is decoupled from temperature in some manner we don't understand. Our human contribution may serve to accelerate or disturb an already natural phenomena.

Here is another article discussing this paper.<blockquote>"Water’s salinity and temperature are properties that can be used to trace its origin – and the warming deep water appeared to come from the Antarctic Ocean, the scientists wrote. This water then was transported northward over 1,000 years via well-known deep-sea currents, a conclusion supported by carbon-dating evidence."</blockquote>This paper also shows how perturbations of local climate can effect the global climate, in that small increases in the solar radiation in the antarctic led to retreating ice sheets, which lowered the albedo of the antarctic which further increases warming. The result of the antarctic warming and natural release of CO2 from the oceans, eventually made its way northward over 1000 years and resulted in the retreat of northern ice sheets (glaciers). I've heard some reports that indicate that antarctic ice sheets are (on average) growing, which will result in more radiation reflected in the antarctic and possibly a colder ocean. Satellite data shows that sea ice has shrunk west of the Antarctic Peninsula and grown in the Ross Sea.
