frozen methane that are currently locked in the world's deep oceans and
permafrost. Passing this climate tipping point would result in global warming that would be far worse and more rapid than scientists' current estimates.</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://blog.wired.com/wiredscience/2008/05/could-methane-t.html">The new paper suggests that exactly this type of cascading release of methane
reserves rapidly warmed the Earth 635 million years ago, replacing an
Ice Age with a period of tropical heat. </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://blog.wired.com/wiredscience/2008/05/could-methane-t.html">Methane is 25 times more potent than carbon dioxide as a
greenhouse gas.</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://blog.wired.com/wiredscience/2008/05/could-methane-t.html">
But not all scientists accept that methane ice is a major threat to the climate.</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://blog.wired.com/wiredscience/2008/05/could-methane-t.html">permafrost temperatures are continuing to rise across the Northern Hemisphere</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://blog.wired.com/wiredscience/2008/05/could-methane-t.html"><div align="center"><img src="http://content6.clipmarks.com/blog_cache/blog.wired.com/img/F9B6E045-B2B2-4084-AA72-329D5266094B" alt="Naturalgashydrate" /></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/B9FFE7D8-F445-4024-8544-32DD7A5FD31B/blog/" title="blog or email this clip"><img src="http://content7.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>
