“…Assuming a change in climate at the close of the Devonian to cooler, glacially influenced conditions, one might expect a decrease in fire frequency rather than an increase based on studies of fire occurrences since the Last Glacial Maximum (LGM): cooler climates result in a lower level of fire occurrence and hence less charcoal accumulation (Power and others, 2008;Daniau, 2010). The lower charcoal occurrence reported for the LGM may be related to an overall decrease in terrestrial biomass and therefore fuel availability (Power, 2013), along with cooler, drier conditions associated with less convection and a reduction in lightning activity, which in turn would mean fewer ignition sources and fires (Power and others, 2008;Power, 2013). Marlon and others (2009) also suggested, however, that fire increased during periods of rapid climate transition from one climate state to another, but our time resolution does not allow the distinction of any very short-term events linked to short-term climate change.…”
