November's Collections of the Month looks at G.S. Callendar, the amateur meteorologist who established the link between carbon dioxide and climate change - 70 years ago. We also look at British scientists who were researching solar energy more than fifty years ago. Above: Guy and Phyllis Callendar, around 1960. Photo courtesy of the G.S. Callendar Archive, University of East Anglia.
