Intanto il carbonio nell’atmosfera continua a crescere e l’effetto serra si intensifica. Davvero non si può fare nient’altro? In effetti sì, tecnicamente si può, e costerebbe anche molto poco. Ma l. a. soluzione proposta si scontra con una comprensibile resistenza da parte di molti. Una delle proposte (mai comunque in opposizione alla riduzione delle emissioni di CO2, che resta un obiettivo necessario) si chiama «geoingegneria», un insieme di tecnologie volte a modificare artificialmente il clima della Terra. los angeles tecnica si basa sul rilascio nella stratosfera di gocce di acido solforico, che agirebbero come un ombrello contro i raggi del Sole. Non parlare di questi temi potrebbe costarci caro. Parlarne in maniera poco informata, anche di più. in line with questo uno dei principali esperti mondiali di tecnologie climatiche ha voluto scrivere questo libro: consistent with discutere in base alle conoscenze e valutare se all’umanità convenga iniziare seriamente a investire nel settore dell’ingegneria ambientale.
