Nell'atmosfera della Terra c'è un nuovo gas serra che finora non era mai stato considerato e che è molto più pericoloso dell'anidride carbonica.
Si chiama "perfluorotributilammina" (PFTBA) ed è stato appena scoperto dagli scienziati del Dipartimento di chimica all'Università di Toronto. Viene usato per diverse applicazioni, tra cui la costruzione di dispositivi elettrici, e poi si disperde nell'ambiente.
"Ha un potenziale impatto sul riscaldamento globale molto alto: una singola molecola ha lo stesso impatto sul riscaldamento globale di 7'100 di quelle di CO2", hanno spiegato gli esperti.
