Loredan was a man of modest culture and limited political experience, having been raised primarily for a life of commerce; in this he stood in stark contrast to his immediate predecessor, Pietro Grimani, who was a poet and diplomat.

Guy Stewart Callendar was an English steam engineer and inventor. His main contribution to knowledge was developing the theory that linked rising carbon dioxide concentrations in the atmosphere to global temperature. He was the first to demonstrate that the Earth’s land temperature had increased over the previous 50 years in 1938. This theory, earlier proposed by Svante Arrhenius, has been called the Callendar effect. Callendar thought this warming would be beneficial, delaying a "return of the deadly glaciers."
