The National Academies of Sciences, Engineering, and Medicine, in collaboration with the Royal Society of Canada, will organize and convene a workshop on the future climate, social, and ecological drivers of wildfire in the western region of the United States and Canada. The workshop will focus on understanding and responding to increasing fire size, severity, and frequency since the 1970s. The public workshop will also focus on policy/practice considerations, research/data needs, and community engagement strategies as it seeks to identify gaps in knowledge, the value of filling those gaps, strategies for doing so, and what disciplines must work together.
