\nFolosind primele modele climatice supercomputerizate ale viitorului \u00eendep\u0103rtat, oamenii de \u015ftiin\u0163\u0103 de la Universitatea din Bristol, Marea Britanie, au prezis cum se vor intensifica extremele climatice dup\u0103 ce continentele lumii vor fuziona pentru a forma un supercontinent, Pangea Ultima, \u00een aproximativ 250 de milioane de ani.<\/p>\n

\nAce\u015ftia au constatat c\u0103 va fi extrem de cald, uscat \u015fi practic de nelocuit pentru oameni \u015fi mamifere, care nu sunt evoluate pentru a face fa\u0163\u0103 expunerii prelungite la c\u0103ldur\u0103 excesiv\u0103.<\/p>\n

\nCercet\u0103torii au simulat evolu\u0163ia temperaturii, a v\u00e2ntului, a ploii \u015fi a umidit\u0103\u0163ii pentru acest supercontinent \u015fi au folosit modele de mi\u015fcare a pl\u0103cilor tectonice, chimia \u015fi biologia oceanelor pentru a calcula nivelurile de dioxid de carbon, relateaz\u0103 CNN.
\nEi au descoperit c\u0103 nu numai c\u0103 formarea Pangea Ultima ar duce la erup\u0163ii vulcanice mai regulate, care ar ar arunca dioxid de carbon \u00een atmosfer\u0103 \u015fi ar \u00eenc\u0103lzi planeta, dar \u015fi c\u0103 soarele ar deveni mai str\u0103lucitor, emi\u0163\u00e2nd mai mult\u0103 energie \u015fi \u00eenc\u0103lzind \u015fi mai mult P\u0103m\u00e2ntul, noteaz\u0103 exper\u0163ii \u00een lucrarea publicat\u0103 luni \u00een revista Nature Geoscience.<\/p>\n

\n“Supercontinentul ar crea efectiv o tripl\u0103 lovitur\u0103 care ar cuprinde efectul de continentalitate, un soare mai fierbinte \u015fi mai mult CO2 \u00een atmosfer\u0103”, a declarat Alexander Farnsworth, cercet\u0103tor asociat la Universitatea din Bristol \u015fi autorul principal al lucr\u0103rii, \u00eentr-un comunicat de pres\u0103 de luni.<\/p>\n

\n“Temperaturile generalizate cuprinse \u00eentre 40 \u015fi 50 de grade Celsius \u015fi extremele zilnice \u015fi mai mari, la care se adaug\u0103 nivelurile ridicate de umiditate, ne-ar pecetlui \u00een cele din urm\u0103 soarta. Oamenii – \u00eempreun\u0103 cu multe alte specii – ar muri din cauza incapacit\u0103\u0163ii lor de a elimina aceast\u0103 c\u0103ldur\u0103 prin transpira\u0163ie, r\u0103corindu-\u015fi corpul”, a ad\u0103ugat Farnsworth.
\nC\u0103ldura crescut\u0103, a precizat Farnsworth, ar crea un mediu f\u0103r\u0103 surse de hran\u0103 sau ap\u0103 pentru mamifere.
\nDe\u015fi exist\u0103 mari incertitudini atunci c\u00e2nd se fac previziuni at\u00e2t de \u00eendep\u0103rtate \u00een viitor, cercet\u0103torii au declarat c\u0103 imaginea pare “foarte sumbr\u0103”, cu doar 8% p\u00e2n\u0103 la 16% din terenul de pe supercontinent locuibil pentru mamifere.
\nUltima extinc\u0163ie \u00een mas\u0103 a avut loc \u00een urm\u0103 cu 66 de milioane de ani, c\u00e2nd un asteroid a lovit P\u0103m\u00e2ntul \u015fi a distrus dinozaurii \u015fi majoritatea formelor de via\u0163\u0103 de pe planet\u0103.
