Une inversion brutale du champ magnétique terrestre il y a 42 000 ans aurait provoqué un dérèglement climatique massif et soudain
Il y a 42 000 ans, une inversion du champ géomagnétique a eu un effet sur le climat de la Terre, selon une étude publiée récemment dans Science. L’Amérique du Nord a réagi avec un signal de refroidissement tandis que l’Europe subissait un léger réchauffement.
