Ought to be some retirement packages revoked. Just the threat might bring "whistle blowers" running to the fore.

"The CO2 levels are “amazingly low,” says Yige Zhang, a paleoclimatologist at Texas A&M University in College Station. He adds that the study, published today in Nature, is “quite interesting” because it reports the first direct measurements of atmospheric gases from that mysterious time."This is not true - the measurements are of the amount of CO2 still in bubbles (that may have formed in depressurizing the ice core) after a million years of CO2 diffusion through the ice under extreme pressure. So the idea that this is a direct measurement is false. "CO2 diffusion in polar ice: observations from naturally formed CO2 spikes in the Siple Dome (Antarctica) ice core
ABSTRACT. One common assumption in interpreting ice-core CO2 records is that diffusion in the ice does not affect the concentration profile. However, this assumption remains untested because the extremely small CO2 diffusion coefficient in ice has not been accurately determined in the laboratory. In this study we take advantage of high levels of CO2 associated with refrozen layers in an ice core from Siple Dome, Antarctica, to study CO2 diffusion rates. We use noble gases (Xe/Ar and Kr/Ar), electrical conductivity and Ca2+ ion concentrations to show that substantial CO2 diffusion may occur in ice on timescales of thousands of years. We estimate the permeation coefficient for CO2 in ice is 4 10–21 molm–1 s–1 Pa–1 at –238C in the top 287m (corresponding to 2.74 kyr). Smoothing of the CO2 record by diffusion at this depth/age is one or two orders of magnitude smaller than the smoothing in the firn. However, simulations for depths of 930–950m (60–70 kyr) indicate that smoothing of the CO2 record by diffusion in deep ice is comparable to smoothing in the firn. Other types of diffusion (e.g. via liquid in ice grain boundaries or veins) may also be important but their influence has not been quantified."

Chole Allen on page 5 lists her occupation as a zoo keeper. go figure Code name for Democrat.

Can you run sheep up there, Sig? Is footrot a problem?

Can you run sheep up there, Sig? Is footrot a problem? Only if they freeze off. Have to watch lambs a bit, the mature ones seem immune to frost bite.
