The windward core tops would be older than the leeward core tops due to transport of snow and ice.

The main conclusion was that ice core dates, in particular those ice cores relied upon the Greenland Ice Core Chronology 2005 (GICC05), such as the NEEM S1 core, were too old by approximately seven years during the 6th and 7th centuries ice core dates, in particular those ice cores relied upon the Greenland Ice Core Chronology 2005 (GICC05), such as the NEEM S1 core, were too old by approximately seven years during the 6th and 7th centuriescore dates, in particular those ice cores relied upon the Greenland Ice Core Chronology 2005 (GICC05), such as the NEEM S1 core, were too old by approximately seven years during the 6th and 7th centuries ice cores relied upon the Greenland Ice Core Chronology 2005 (GICC05), such as the NEEM S1 core, were too old by approximately seven years during the 6th and 7th centuries Ice Core Chronology 2005 (GICC05), such as the NEEM S1 core, were too old by approximately seven years during the 6th and 7th centuriesCore Chronology 2005 (GICC05), such as the NEEM S1 core, were too old by approximately seven years during the 6th and 7th centuriescore, were too old by approximately seven years during the 6th and 7th centuries AD.

The work by Vinther and colleagues in Southern Greenland is therefore key to helping calibrate the Greenland ice core records, and impressively, the correlations to the older data are as good as to the recent record, allowing us to have a little more confidence in the even longer term proxy data for this region.

BPL: The warming trend is not twenty years old, but 165 years old by direct measurements and perhaps 250 years old if you include ice - core data.

We don't really know the magnitude of that lag as well as Barton implies we do, because it is very challenging to put CO2 records from ice cores on the same timescale as temperature records from those same ice cores, due to the time delay in trapping the atmosphere as the snow is compressed into ice (the ice at any time will always be younger older than the gas bubbles it encloses, and the age difference is inherently uncertain).

That can be seen in the old data (high wind speed gives values near the ice core levels) as good as in modern data.

From those ice cores she has found traces of sulfuric acid (defined) from volcanic plumes and extracted microscopic «shards» of volcanic dust, some more than 20,000 years old.

As of now, the oldest recovered, reliable ice cores stretch back around 800,000 years, during an ice age when the atmosphere was about 185 ppm carbon dioxide.

1) Ice cores 2) Old Viking farmlands in Greenland.

Other problems with the ice cores include meltwater moving through the ice; Bacteria in the ice releasing gases even in 500,000 - year - old ice at great depth; and contamination and losses during drilling and core recovery process.

He illustrated the science with PowerPoint slides that showed the relationship between the sun and the Earth's atmosphere, and how scientists track centuries - old temperature data with tree rings and ice cores.

Greenland's ice core data is only 200,000 years old.

This newborn arctic hockey stick is not supported by numerous older reconstructions, for example ice cores from Central Greenland.

Wenk Physics Institute, University of Bern, CH — 3012 Bern, Sidlerstrasse 5, Switzerland Studies on air trapped in old polar ice1, 2 have shown that during the last ice age, the atmospheric carbon dioxide concentration was probably significantly lower than during the Holocene — about 200 p.p.m. rather than 270 p.p.m.. Also, Stauffer et al. 3 recently showed by detailed analyses of Greenland ice cores, that during the ice age, between about 30,000 and 40,000 yr BP, the atmospheric CO2 level probably varied between 200 and 260 p.p.m..

The bottom and older layers do get squeezed by the weight above, but reliable ice cores that are hundreds of thousands of year old have been recovered.

That makes that the average age of the air mixture at closing depth of the high resolution Law Dome ice cores is only 7 years older than in the above atmosphere.

Although the time resolution of old air locked in ice cores is not enough to preserve seasonal cycles, there is no doubt that the seasonal cycle, which is mostly caused by photosynthesis and respiration of ecosystems on land, was similar to what we observe today.

The older than Mauna Loa results of CO2 contents used in the models adopted by IPCC are ice core proxy values of carbon dioxide content, which are incompatible with any one of directly measured values, already therefore that, even at their best, they are averages of some centuries.

At 72 meter depth (for the Law Dome ice cores) the CO2 level in average still is only 7 years older than the air at the surface.

They report larger variations in measured CO2 with per - cm vertical distance in younger ice earlier in an ice core clathrate zone, and smaller variations in older ice at deeper core, consistent with increasing homogeneity with time.

Proxy trees that are several hundred years old or proxy [insect (chironomids) or planktonic] sediments would have patterns that could be compared to the ice cores.

The Greenland ice core finding was not expected (the old consensus belief was that climate changes were gradual) and many at first stated the planet's climate could not possibly change that rapidly.

In this link https://bravenewclimate.com/2016/09/10/open-thread-26/#comment-470348 I briefly outline the results of an important paper which uses Liang causality, a statistical notion superior to the older Granger causality, to analyze the climate data, both ice core and recent, to obtain the expected result that CO2 Liang causes global warming in recent times but the opposite conclusion for the paleodata.
