\nAsteroidul Bennu se apropie de P\u0103m\u00e2nt la fiecare \u015fase ani. Oamenii de \u015ftiin\u0163\u0103 au calculat o probabilitate de 1 din 2.700 privind o coliziune cu P\u0103m\u00e2ntul \u00een anul 2182, potrivit Reuters. Ei au mers mai departe cu cercet\u0103rile \u015fi au \u00eencercat s\u0103 afle ce se va \u00eent\u00e2mpla \u00een cazul pu\u0163in probabil al unei coliziuni.<\/p>\n
\nEi au f\u0103cut simul\u0103ri computerizate \u015fi au stabilit c\u0103 pe l\u00e2ng\u0103 craterul ini\u0163ial, un \u015fir de dezastre se vor declan\u015fa pe planet\u0103. Sute de milioane de tone de praf vor ajunge \u00een atmosfer\u0103, provoc\u00e2nd perturb\u0103ri ale climei \u015fi fotosintezei cu o durat\u0103 de trei p\u00e2n\u0103 la patru ani pe tot globul. Lumina pe planet\u0103 va fo sc\u0103zut\u0103. Temperatura se va reduce \u015fi vor fi pu\u0163ine precipita\u0163ii, a explicat Lan Dai, cercet\u0103tor la Centrul IBS pentru Fizica Climei (ICCP) de la Universitatea Na\u0163ional\u0103 Pusan din Coreea de Sud.<\/p>\n
\nStudiul publicat s\u0103pt\u0103m\u00e2na aceasta \u00een revista Science Advances arat\u0103 c\u0103 \u00een cel mai r\u0103u scenariu, temperatura medie la suprafe\u0163ei P\u0103m\u00e2ntului ar sc\u0103dea cu aproximativ 4 grade Celsiu), precipita\u0163iile medii ar sc\u0103dea cu 15%, ar exista o reducere de p\u00e2n\u0103 la 20-30% a fotosintezei plantelor \u015fi o epuizare de 32% a stratului de ozon. De asemenea, impactul va provoca cutremure, incendii, radia\u0163ii \u015fi erup\u0163ii vulcanice.<\/p>\n
\nCercet\u0103torii nu au stabilit \u015fi num\u0103rul deceselor. Acest lucru depinde de locul \u00een care se produce impactul asteroidului.<\/p>\n","protected":false},"excerpt":{"rendered":"
