Consequently, without microbes breaking down methane in the water, much more will enter the atmosphere.

We've got to get people to stop emitting if it kills us NOW cause it is anyway. Just make it happen . NO 2nd hand GHG smoke for me thank you or fuck you or what ever just stop it now! Then we can figure out how to start taking it back after we stop doing it in the 1st place. This is WW3. We need a WW3 level of mobilization to make the necessary transition to minus 0 emission NOW.Anonymoushttps://www.blogger.com/profile/08518220316241253226noreply@blogger.comtag:blogger.com,1999:blog-1641696877572843922.post-64360806448644547772014-05-12T22:56:10.351-07:002014-05-12T22:56:10.351-07:00No ,No ...our Corporate "Govt has issued perm...No ,No ...our Corporate "Govt has issued permits for Fracking on land and in combination with the Deep sea Drilling" !

EVER. Our conservative Govt has issued permits for Fracking on land and in combination with the Deep sea Drilling ( contracts let to Aanadarko, so far they have been unsuccessful) Any further advice on this matter will be greatly received , sent to the Greens and used to get rid of this Drill and Frack bunch of Fossil Fool fiends.

As I understand it the clathrate is formed by gas passing through water from below and being caught when the water freezes. Once the methane is out it could take a long time, perhaps millions of years, with the best conditions for it to get stashed away again.<br />keithullmanhttps://www.blogger.com/profile/00525734470966762625noreply@blogger.comtag:blogger.com,1999:blog-1641696877572843922.post-65005097931040077932014-05-12T05:33:52.985-07:002014-05-12T05:33:52.985-07:00There are huge, 10km pock marks from methane relea...There are huge, 10km pock marks from methane release in sea floor off New Zealand. Considering Enrico Pv Dr Light described at End of Eurasian basin in Arctic Sea and deep sourced methane on top of all else and the methane anomaly that showed up over central Antarctica in sky for months last year. Considering this and lag time till ocean uptake of CO2 expresses as pH change, I think we are quite well cooked...Dale Lananhttps://www.blogger.com/profile/05409842680440987251noreply@blogger.comtag:blogger.com,1999:blog-1641696877572843922.post-84266091166321138272014-05-11T21:42:20.507-07:002014-05-11T21:42:20.507-07:00Just to clarify the following, where the news rele...Just to clarify the following, where the news release talks about frozen methane, this refers to methane held in hydrates, also known as clathrates. A clathrate is a chemical substance consisting of a lattice that traps or contains molecules. The word clathrate is derived from the Latin clatratus meaning with bars or a lattice. In a methane hydrate, methane is held in water ice. Methane hydrates can become unstable either due to a rise in temperature or a fall in pressure, or a combination of them. A temperature rise can make that the ice structure (that holds the methane) starts melting. The freezing/melting point of water is 0°C, When the hydrate breaks down, the methane inside loses pressure and expands to 160 x the volume it had when held inside the hydrate. <br /><br />Methane in hydrates is very different from LNG (liquified natural gas), which is methane that is transformed into a liquid at close to atmospheric pressure (maximum transport pressure set at around 25 kPa (4 psi)) by cooling it to approximately −162 °C (−260 °F). When methane is cooled even further, it becomes solid, which occurs at a temperature of -183°C, which is methane's melting point. The above -162°C is also referred to as methane's boiling point.
