vestea buna e ca o sa murim destepti

daca nu stiati, avem pe la Pol si niste gigatone de gaz metan inghetat prins in gheata din Antarctica, Sberia, etc., niste pungi imense, dupa cum tocmai s-a stabilit...partea proasta e ca gheata de la Pol se, si anume, topeste datorita incalzirii globale, daca mai e cineva care nu a aflat.
...metanul fiind de nush cate ori mai poluant decat CO2...

"daca gazul metan dintr-o mica fractie a depozitelor de metan de pe fundul oceanului arctic e eliberata in aer, we're fucked"
spune un expert climatolog, pe nume Jason Box, de la Geological Survey of Denmark and Greenland, reactia sa fiind declansata de un studiu publicat de un raport public al Universitatii de la Stockholm, conform caruia : “vast methane plumes escaping from the seafloor” in the Arctic Ocean.

(Professor Jason Box of the Geological Survey of Denmark and Greenland tweeted “If even a small fraction of Arctic sea floor carbon is released to the atmosphere, we're fucked.” )

citez de la Box de pe blog :
"The Swedish team states “At several places, the methane “bubbles“ even rose to the ocean surface. That’s damn scary. Atmospheric methane release is a much bigger problem than atmospheric carbon dioxide release, since methane is ~20 times more powerful greenhouse gas. If as it seems, sea ice reduction is destabilizing the shallow Arctic Ocean continental shelf waters. Without the reflective cover, the ocean is taking on a lot more solar heating during the 24 h summer days, making it harder for the sea ice to reform, in a self compounding feedback process. Places like the Laptev and East Siberian seas, are shallow, and the water column can more easily be mixed by wind action than when sea ice cover was there. This new heating and mixing can be what unlocks the shallow sea gas hydrates, allowing the methane up to the surface. "

ca sa nu murim prosti (daca asta ar mai putea fi o consolare)  BBC ne-a explicat cum e cu gazul prins in gheata



si, apropo de craterele aparute in Siberia, un nene de la NASA care rade ca un bou, desi stie perfect ca e groasa. presupun ca e fericit ca va muri destept; pare genul.

  2. eu sper ca stii ca nenea asta pe care mi-l recomanzi este un sustinator - cu grad de expert - al fracturarii hidraulice/gazelor de sist.

  3. nota bene: uita de Cranganu, sunt multe neclaritati in legatura cu el.
    Si eu oricum n-am timp acum sa vad care e de fapt treaba cu el. Pe la inceput a scris diverse lucruri, dar asta am impresia ca a fost atunci
