\nPoluarea cu metan, un gaz cu efect de ser\u0103, cre\u015fte alarmant, iar oamenii sunt principalii responsabili. Cercet\u0103torii au descoperit c\u0103 \u00een 2020, lumea a eliberat \u00een atmosfer\u0103 cu 12% mai mult metan dec\u00e2t \u00een anul 2000.<\/p>\n
\nRob Jackson, director al Global Carbon Project \u015fi autor principal al studiului publicat \u00een Environmental Research Letters, avertizeaz\u0103: \u201eMetanul este o amenin\u0163are climatic\u0103 pe care lumea o ignor\u0103. A crescut mult mai mult \u015fi mai rapid dec\u00e2t dioxidul de carbon”.<\/p>\n
\n\u00cen 2020, s-au emis 670 de milioane de tone de metan \u00een atmosfer\u0103. Emisiile cauzate de om au crescut cu 18% \u00een ultimii 20 de ani, noteaz\u0103 AP.<\/p>\n
\nNivelul actual de metan din aer este de 2,6 ori mai mare dec\u00e2t \u00een era preindustrial\u0103. 65% din metanul emis provine acum din activit\u0103\u0163i umane, fa\u0163\u0103 de 60% \u00een anul 2000.<\/p>\n
\nPrincipalele surse de metan produse de om sunt extrac\u0163ia de c\u0103rbune, petrol \u015fi gaze (cre\u015ftere de 33% \u00een 20 de ani), depozitele de de\u015feuri (cre\u015ftere de 20%) \u015fi agricultura (cre\u015ftere de 14%).<\/p>\n
\nDe\u015fi metanul r\u0103m\u00e2ne \u00een atmosfer\u0103 doar aproximativ 10 ani, efectul s\u0103u de \u00eenc\u0103lzire este mult mai puternic dec\u00e2t al dioxidului de carbon. Exper\u0163ii cred c\u0103 reducerea emisiilor de metan ar putea aduce beneficii rapide \u00een lupta \u00eempotriva schimb\u0103rilor climatice.<\/p>\n
\nBill Hare, CEO al Climate Analytics, consider\u0103 studiul \u201efoarte \u00eengrijor\u0103tor” \u015fi subliniaz\u0103 necesitatea reducerii emisiilor de metan cu peste o treime pentru a men\u0163ine \u00eenc\u0103lzirea global\u0103 sub 1,5\u00b0C.<\/p>\n
\nJackson avertizeaz\u0103 c\u0103 tendin\u0163a actual\u0103 ne \u00eendreapt\u0103 spre o \u00eenc\u0103lzire de 3\u00b0C, dublu fa\u0163\u0103 de \u0163inta Acordului de la Paris. El adaug\u0103 c\u0103, de\u015fi \u0163\u0103rile au promis \u00een 2021 s\u0103 ac\u0163ioneze \u00eempotriva metanului, efectele nu se v\u0103d \u00eenc\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
