La terre vomit du méthane ou comment allons nous crever
By AkH, 3 years, 2 months ago, modified Nov. 13, 2008
En lisant "Sciences et Vie Avenir" de ce mois ci (nan pas celui là avec les extra terrestres l'autre), sur une demi page dans un article discret, on découvre ni plus ni moins que: la fin du monde, dans un futur ... proche.
Depuis plusieurs années maintenant, on nous apprend que le méchant CO2, générateur de tous les maux de la planète, va augmenter la température et nous faire crever à petit feu.
On savait aussi que l'activité humaine, notamment l'élevage, générait du méthane, gaz bien plus générateur d'effet de serre, mais que les quantités rejetées étaient suffisamment peu élevées pour ne pas s'inquiéter.
Mais oh surprise le permafrost arctique regorge de méthane et il est en train de fondre et de relacher des quantités "industrielles" (hahaha) de méthane.
Aucun modèle n'avait prévu un apport aussi important de méthane dans l'atmosphère, on peut voir à l'oeil nu des bulles de méthanes remontées, les articles de futura-science et du monde
Notre nouveau tueur d'humanité: le CH4
On va se faire un Perrier pour fêter ca ?

adore in <a href="http://www.coachstorehandbags.com/coach-new-arrivals-c-1.html">Coach New Arrivals</a> a saddlebag like
this. Just in time for winter tweeds and browns, the color of this bag will also easily transition into spring wardrobes
because of <a href="http://www.mulberryoutlet-sale.com/mulberry-clutch-bags-c-6.html">Mulberry Clutch Bags</a> its light hue.
While the inside is not entirely lined with suede, there are suede accents along with a stamped canvas

fastening tab for the fold-over flap. It has been a while since a Mulberry bag stood out on my radar, and the Evelina is
quite cute.After I wrote the title for this post, I realized that I am an over-user of
<a href="http://www.coachstorehandbags.com/coach-new-arrivals-c-1.html">Coach New Arrivals</a> the word chic. Still, though,
many times it seems like a fitting word for many different items,
<A href="http://www.handbagssale-online.com/Louis-Vuitton-Handbags.html">Louis Vuitton bags</A> and the Mulberry Evelina
deserves to be called chic.

In the past, I’ve found many Mulberry bags to be a tad masculine, and the Evelina’s name matches the silhouette. A touch
of femininity with a ton of usability makes me love this Mulberry bag.
