\nPotrivit unui studiu publicat mar\u0163i la Glasgow, cre\u015fterea temperaturii va dep\u0103\u015fi 2,4\u00b0C p\u00e2n\u0103 la sf\u00e2r\u015fitul acestui secol, pe baza obiectivelor pe termen scurt stabilite de \u0163\u0103ri.<\/p>\n
\nAcest lucru ar dep\u0103\u015fi cu mult limita superioar\u0103 de 2C, care, conform Acordului de la Paris, ar trebui s\u0103 r\u0103m\u00e2n\u0103 “cu mult sub” 2C, precum \u015fi limita mult mai sigur\u0103 de 1,5C, care a fost stabilit\u0103 \u00een cadrul discu\u0163iilor de la Cop26.<\/p>\n
\nLa acest nivel, fenomenele meteorologice extreme – cre\u015fteri ale nivelului m\u0103rii, secet\u0103, inunda\u0163ii, valuri de c\u0103ldur\u0103 \u015fi furtuni mai puternice – ar provoca distrugeri pe tot globul.<\/p>\n
\nEstimarea contrasteaz\u0103 puternic cu previziunile optimiste publicate s\u0103pt\u0103m\u00e2na trecut\u0103, care sugerau c\u0103 \u00eenc\u0103lzirea ar putea fi men\u0163inut\u0103 la 1,9C sau 1,8C, \u00een urma angajamentelor anun\u0163ate \u00een cadrul negocierilor, aflate acum \u00een a doua s\u0103pt\u0103m\u00e2n\u0103 \u015fi programate s\u0103 se \u00eencheie \u00een acest weekend.<\/p>\n
\nAcele estim\u0103ri se bazau pe obiectivele pe termen lung stabilite de \u0163\u0103ri, inclusiv India, al treilea mare poluator din lume, care \u00ee\u015fi propune s\u0103 ating\u0103 un nivel zero de emisii nete p\u00e2n\u0103 \u00een 2070.<\/p>\n
\n\u00cen schimb, evaluarea sumbr\u0103 a unei cre\u015fteri de 2,4C, realizat\u0103 de Climate Action Tracker (CAT), cea mai respectat\u0103 coali\u0163ie de analiz\u0103 climatic\u0103 din lume, s-a bazat pe obiectivele pe termen scurt ale \u0163\u0103rilor pentru urm\u0103torul deceniu.<\/p>\n
\nConform promisiunilor f\u0103cute la Glasgow, emisiile vor fi de dou\u0103 ori mai mari \u00een 2030 dec\u00e2t ar trebui s\u0103 fie pentru a nu dep\u0103\u015fi 1,5C, a constatat CAT. Oamenii de \u015ftiin\u0163\u0103 au avertizat c\u0103, dincolo de 1,5C, unele dintre daunele aduse climei P\u0103m\u00e2ntului vor deveni ireversibile.<\/p>\n
\nAnali\u015ftii au constatat, de asemenea, o pr\u0103pastie \u00eentre ceea ce au declarat \u0163\u0103rile c\u0103 vor face \u00een privin\u0163a emisiilor de gaze cu efect de ser\u0103 \u015fi planurile lor din realitate. Dac\u0103 se iau \u00een considerare politicile \u015fi m\u0103surile actuale, \u015fi nu doar obiectivele, \u00eenc\u0103lzirea ar cre\u015fte la 2,7C, conform analizei CAT.<\/p>\n
\nCele 197 de p\u0103r\u0163i la Acordul de la Paris din 2015 au fost rugate s\u0103 vin\u0103 la Glasgow cu dou\u0103 obiective: un obiectiv pe termen lung de a ajunge la zero emisii nete la nivel global \u00een jurul jum\u0103t\u0103\u0163ii secolului \u015fi planuri na\u0163ionale pe termen mai scurt, care fixeaz\u0103 reducerea emisiilor p\u00e2n\u0103 \u00een 2030. Oamenii de \u015ftiin\u0163\u0103 spun c\u0103 emisiile de gaze cu efect de ser\u0103 trebuie s\u0103 scad\u0103 cu aproximativ 45% \u00een acest deceniu pentru ca temperaturile globale s\u0103 nu dep\u0103\u015feasc\u0103 1,5 grade Celsius fa\u0163\u0103 de nivelurile preindustriale.<\/p>\n
\nPrima s\u0103pt\u0103m\u00e2n\u0103 a discu\u0163iilor din cadrul Cop26 a fost dominat\u0103 de o avalan\u015f\u0103 de anun\u0163uri, inclusiv angajamente privind conservarea p\u0103durilor, finan\u0163area sectorului privat pentru energie curat\u0103 \u015fi eliminarea treptat\u0103 a c\u0103rbunelui de c\u0103tre \u0163\u0103ri. Ulterior, \u0163\u0103rile au p\u0103rut s\u0103 revin\u0103 asupra unor angajamente sau au sim\u0163it nevoia s\u0103 le clarifice.<\/p>\n","protected":false},"excerpt":{"rendered":"
