The Quaternary period has well-defined glacial-interglacial periodicity on the Milankovitch to sub-millennial time scale. However, some of these glacial-interglacial events were different from the regular periodicity and brought significant changes in the global climate and are recorded across the proxies. A few of these distinct Quaternary extreme events are M-1 glaciations, Middle Pleistocene Transition, Mid-Brunhes Event/Transition and Last Glacial Maximum. Other important events include the Younger Dryas and the Little Ice Age. Besides these long-term events, several short-term decadal to centennial-scale standalone events also mark the Quaternary. Climate, Ocean, Monsoon, and associated processes also varied on these time scales. The response, however, was different in different regions. We invite contributions that deal with any extreme climate (including Monsoon) and associated events during the Quaternary.
