ScienceDaily: Scientists from U of T's Department of Chemistry have discovered a novel chemical lurking in the atmosphere that appears to be a long-lived greenhouse gas (LLGHG). The chemical -- perfluorotributylamine (PFTBA) -- is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate.
Radiative efficiency describes how effectively a molecule can affect climate. This value is then multiplied by its atmospheric concentration to determine...
