Well it means that all "top atmospheric scientists" do not have a clue about superposition. Simply put the whole is a sum of it's parts.

You and they deny the meaning of the non disputed. toms.homeip.net

Where is the list of these "top atmospheric scientists" Is that list 100 million long or 2 long?

What is the latest on Ice Cores.

“The ice cores show a nearly synchronous relationship between the temperature in Antarctica and the atmospheric content of CO2, and this suggests that it is the processes in the deep-sea around Antarctica that play an important role in the CO2 increase,” explains Sune Olander Rasmussen.

New research in Antarctica shows CO2 follows temperature “by a few hundred years at most”

The question of “which comes first, the temperature or the CO2 rise?” has been much like the proverbial “which came first, the chicken or the egg?” question. This seems to settle it – temperature came first, followed by an increase in CO2 outgassing from the ocean surrounding Antarctica.

“Our analyses of ice cores from the ice sheet in Antarctica shows that the concentration of CO2 in the atmosphere follows the rise in Antarctic temperatures very closely and is staggered by a few hundred years at most,” - Sune Olander Rasmussen

Lag histograms for the two methods of determining the lag of atmospheric CO2 after regional Antarctic temperature changes (direct correlation and correlation of derivatives), using each of the two CO2 data sets (Byrd and Siple Dome). The gray background histograms are based on the complete Tproxy composite, the same as in Fig. 1b. The superimposed curves show the corresponding lag histograms when excluding in turn each of the 5 records from the Tproxy composite (jack-knifing): excluding Siple (red), excluding Law Dome (green), excluding Byrd (blue), excluding EDML (cyan), and excluding Talos Dome (magenta).

From the University of Copenhagen - Rise in temperatures and CO2 follow each other closely in climate change

The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period. New research from the Niels Bohr Institute at the University of Copenhagen indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time. The results have been published in the scientific journal, Climate of the Past.

In the warmer climate the atmospheric content of CO2 is naturally higher. The gas CO2 (carbon dioxide) is a green-house gas that absorbs heat radiation from the Earth and thus keeps the Earth warm. In the shift between ice ages and interglacial periods the atmospheric content of CO2 helps to intensify the natural climate variations.

It had previously been thought that as the temperature began to rise at the end of the ice age approximately 19,000 years ago, an increase in the amount of CO2 in the atmosphere followed with a delay of up to 1,000 years.

“Our analyses of ice cores from the ice sheet in Antarctica shows that the concentration of CO2 in the atmosphere follows the rise in Antarctic temperatures very closely and is staggered by a few hundred years at most,” explains Sune Olander Rasmussen, Associate Professor and centre coordinator at the Centre for Ice and Climate at the Niels Bohr Institute at the University of Copenhagen.

Deep-sea’s important role The research, which was carried out in collaboration with researchers from the University of Tasmania in Australia, is based on measurements of ice cores from five boreholes through the ice sheet in Antarctica. The ice sheet is formed by snow that doesn’t melt, but remains year after year and is gradually compressed into kilometers thick ice. During the compression, air is trapped between the snowflakes and as a result the ice contains tiny samples of ancient atmospheres. The composition of the ice also shows what the temperature was when the snow fell, so the ice is an archive of past climate and atmospheric composition.

“The ice cores show a nearly synchronous relationship between the temperature in Antarctica and the atmospheric content of CO2, and this suggests that it is the processes in the deep-sea around Antarctica that play an important role in the CO2 increase,” explains Sune Olander Rasmussen.
