Permafrostul este solul \u00eenghe\u021bat permanent din regiunile nordice ale planetei. \u00cen acest sol se ascunde o cantitate colosal\u0103 de carbon acumulat de-a lungul miilor de ani.<\/p>\n

Odat\u0103 cu \u00eenc\u0103lzirea global\u0103, permafrostul se dezghea\u021b\u0103, iar microbii din interior \u00eencep s\u0103 \u201erespire\u201d din nou, scrie Futura Sciences<\/a>.<\/p>\n

Prin aceast\u0103 activitate, microbii transform\u0103 carbonul din sol \u00een dioxid de carbon \u0219i metan, agrav\u00e2nd \u0219i mai mult \u00eenc\u0103lzirea global\u0103.<\/p>\n

Ce au descoperit cercet\u0103torii americani<\/h2>\n

Studiul a fost publicat \u00een revista Nature Microbiology de c\u0103tre cercet\u0103tori de la Universitatea din Colorado.<\/p>\n

Practic, microbii din permafrost pot consuma \u0219i tipuri de carbon pe care oamenii de \u0219tiin\u021b\u0103 le considerau de neatins. Este vorba despre polifenoli, compu\u0219i despre care se credea c\u0103 blocheaz\u0103 activitatea microbian\u0103 \u00een sol.<\/p>\n

\u201eExist\u0103 organisme care consum\u0103 m\u00e2ncarea picant\u0103. Prin urmare, polifenolii nu vor r\u0103m\u00e2ne sub form\u0103 de carbon \u00een sol, ci pot fi descompu\u0219i\u201d, explic\u0103 Bridget McGivern, autoarea principal\u0103 a studiului.<\/p>\n

Estim\u0103rile anterioare indicau deja emisii de gaze cu efect de ser\u0103 din permafrost comparabile cu cele ale marilor \u021b\u0103ri industrializate, p\u00e2n\u0103 \u00een 2100.<\/p>\n

Noul studiu sugereaz\u0103 c\u0103 aceste estim\u0103ri ar putea fi chiar subdimensionate.<\/p>\n

Un plan de combatere a \u00eenc\u0103lzirii globale, compromis<\/h2>\n

Unii cercet\u0103tori mizau pe ad\u0103ugarea de polifenoli \u00een solul care se dezghea\u021b\u0103 pentru a bloca activitatea microbilor \u0219i a capta carbonul \u00een permafrost.<\/p>\n

Noul studiu arat\u0103 c\u0103 aceast\u0103 strategie ar putea avea efectul opus \u0219i ar agrava problema.<\/p>\n

entru a cuantifica cu precizie cantitatea suplimentar\u0103 de gaze cu efect dFoto: freepik ser\u0103 care ar putea emana din permafrostul dezghe\u021bat, sunt necesare studii mai detaliate.<\/p>\n

Descoperirea r\u0103m\u00e2ne \u00eens\u0103 un semnal de alarm\u0103 important pentru comunitatea \u0219tiin\u021bific\u0103 \u0219i pentru factorii de decizie \u00een domeniul climei.<\/p>\n","protected":false},"excerpt":{"rendered":"
