<div>All:<br><br>A recent report in the November 25, 2005 edition of "Science" magazine, volume 310, focusing on ice core </div>
<div>samples from Antarctica, provides more scientific backing to support the need to reduce human sourced </div>
<div>CO2 emissions into our atmosphere, to lessen the impact of "greenhouse effect" caused global warming.<br><br>This volume of "Science" contains several articles focused on the study of ice core samples related to
</div>
<div>climate change and CO2, etc.<br><br>In the first paragraph of an article titled "Tiny Bubbles" (a title no doubt aimed at making the article more </div>
<div>friendly for the general non-technical reader), authored by Edward J. Brook, on page 1285, the following quote appears. Web link to article first:</div>

<div><br>"Until recently, the longest of the ice core records (from Vostok station in Antarctica) extended back </div>
<div>440,000 years (1). Now, reports by Siegenthaler et. al. on page 1313 (2) and by Spahni et. al. on page </div>
<div>1317 (3) extend our window into the past an additional 210,000 years."<br><br>This quote in volume 310 of "Science" makes it perfectly clear the time span involved in the reports from the </div>
<div>ice core samples from this same volume of "Science" extend to 650,000 years ago, not before.<br><br>The possibility of taking ice core samples from earlier periods in Earth's history is discussed in the New
</div>
<div>Scientist article at the web link below, along with some results of the findings reported in "Science," volume 310, that </div>
<div>current atmospheric CO2 levels are higher than at any time in the past 650,000 years:</div>

<div> </div>
<div>Also from this New Scientist web site article is the following quote derived from information in the ice core sample study </div>
<div>published in the same volume of "Science," providing increasing evidence that human sourced CO2 is dramatically altering atmospheric CO2 levels:</div>
<div> </div>
<div>"Today's level of 380 parts per million of carbon dioxide is 27% above its previous peaks of about 300 ppm, </div>
<div>according to the team led by Thomas Stocker of the University of Bern in Switzerland."</div>
<div> </div>
<div>The same New Scientist article makes it clear that these figures apply to the last 650,000 years, when stating:</div>
<div> </div>
<div>"The frozen record of the Earth's atmosphere is 3270 metres long and covers the last 650,000 years – 50% </div>
<div>longer than before. It was obtained from the tiny air bubbles trapped in a deep ice core from Antarctica."</div>
