For the moment, the amount of methane in the atmosphere is 
steady after leveling off around 1999, said Fraser, leader of 
the Changing Atmosphere Research Group at Australia's 
government-funded Commonwealth Scientific and Industrial 
Research Organization.</p> <P> This is thought to be because the drying out of tropical 
wetlands seems to canceling out a rise in emissions from the 
oil and gas industry. But how long this lasts is anyone's 
guess.</P></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://www.sciam.com/article.cfm?alias=the-heat-is-on-for-greenh"> In the United States, cattle emit about 5.5 million tonnes 
of methane per year into the atmosphere, accounting for 20 
percent of U.S. methane emissions, the Environmental Protection 
Agency says. </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://www.sciam.com/article.cfm?alias=the-heat-is-on-for-greenh"><P>what worries Singer most is a rapid release of methane 
stored in sub-polar permafrost or in huge methane hydrate 
deposits under the sea. While this has not happened, some 
scientists suggest it might occur in a warmer world.</p> <P> "If methane hydrates leak, then we're gone, then it's 
over."</P></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/BA293EC1-73A1-4119-8CF0-5A3076CA2F1B/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>
