In recent centuries, however, CO<SUB>2</SUB> levels have risen sharply, to at least 380 ppm</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://environment.newscientist.com/channel/earth/climate-change/dn11638">So what's going on? It is true that human emissions of CO<SUB>2</SUB> are small compared with natural sources. But the fact that CO<SUB>2</SUB> levels have remained steady until very recently shows that natural emissions are usually balanced by natural absorptions. Now slightly more CO<SUB>2</SUB> must be entering the atmosphere than is being soaked up by carbon "sinks".</blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content6.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://environment.newscientist.com/data/images/ns/cms/dn11638/dn11638-4_738.jpg" href="http://environment.newscientist.com/data/images/ns/cms/dn11638/dn11638-4_738.jpg" style="font-size: 11px;">environment.newscientist.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://environment.newscientist.com/data/images/ns/cms/dn11638/dn11638-4_738.jpg"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/environment.newscientist.com/img/A1BA640B-8FE5-45D3-B349-3C343C8A8A0B" alt="http://environment.newscientist.com/data/images/ns/cms/dn11638/dn11638-4_738.jpg" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/D471E188-659C-4203-9343-1645E9572E94/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
