Synthesis of Knowledge: Fire History and Climate Change
This report synthesizes available fire history and climate change scientific knowledge to aid managers with fire decisions in the face of ongoing 21st century climate change. Fire history and climate change (FHCC) have been ongoing for over 400 million years of Earth history, but increasing human influences during the Holocene Epoch have changed both climate and fire regimes. We describe basic concepts of climate science and explain the causes of accelerating 21st century climate change. Fire regimes and ecosystem classifications serve to unify ecological and climate factors influencing fire, and are useful for applying fire history and climate change information to specific ecosystems. Variable and changing patterns of climate-fire interaction occur over different time and space scales that shape use of FHCC knowledge. Ecosystem differences in fire regimes, climate change, and available fire history mean that using an ecosystem-specific view will be beneficial when applying FHCC knowledge

The rise of Public History: an international perspective
This article explores the birth and development of public history and presents the different criteria of its internationalization from the 1970s to the more recent creation of the International Federation of Public History. Based mostly on North America and Europe, the international perspective sets the development of public history in the United States into a broader context of debates about the changing role of historians. While public history was mostly perceived in the 1980s as the application – through consulting – of history to present- day issues, the more recent internationalization is made of a variety of local and national approaches to the field
Synthesis of Knowledge: Fire History and Climate Change
This report synthesizes available fire history climate change scientific knowledge to aid managers with fire decisions in tile face of ongoing 21st Century cIimate change. Fire history and climate change mange (FHCC} have been ongoing for over 400 million years of Earth history, but increasing human influences during tile Holocene epoch have changed both climate and fire regimes. We describe basic concepts of climate science and explain the causes of accelerating 21H Century climate change. Fire regimes and ecosystems classification serve to unify ecological and climate factors influencing fire, and are useful for applying fire history and climate manage information to specific ecosystems. Variable and changing patterns of climate-fire interaction occur over different time and space scales that shape use of FHCC knowledge. Ecosystem differences in fire regimes, climate change and available fire history mean that using an ecosystem specific view will be beneficial when applying FHCC knowledge
