Les scientifiques de Harvard prévoient de lancer un ballon à haute altitude au-dessus de la Laponie en juin prochain, première phase d’une expérience de géoingénierie. Objectif : refroidir la Terre en atténuant, par le lâcher de microparticules, le rayonnement solaire. Les groupes environnementaux suédois s’insurgent contre l’adoption d’une technologie potentiellement « dangereuse,
