Description:In Part 1 (Vali and Schnell, 2024; VS24) we described the discoveries we and our associates made in the 1960s and 1970s about biological ice nucleators (bio-INPs). Bio-INPs are far more effective than mineral INPs at temperatures above −10°C. The bio-INPs were found in decayed vegetation and in ocean water, then bacteria were identified as being the most active source for this remarkable activity. In this Part 2, we recount how, within a few years, the worldwide distribution of bio-INP sources was shown to correlate with climate zones, as was the abundance of INPs in precipitation. Oceanic sources were further studied and the presence of bio-INPs in fog diagnosed. The potential for release of bio-INPs from to the atmosphere was demonstrated. Bacterial INPs were found to play a crucial role in a plant’s frost resistance. These and other early developments of biological INPs are described. A bibliography of related recent literature is presented in the online Part 1 Supplemental Material.
