Join us for a discussion about urban wildfires in the context of a changing climate. Sign up for the Climate at the National Academies newsletter Read the highlights: The Growing Challenge of Urban Wildfires Relevant Resources: The Social-Ecological Consequences of Future Wildfire and Smoke in the West (2024) The Chemistry of Fires at the Wildland-Urban Interface (2022) Wildland Fires: Toward Improved Understanding and Forecasting of Air Quality Impacts (2022) Why and When is Respiratory Protection Needed? (2022) Implications of the California Wildfires for Health, Communities, and Preparedness (2020) About the Event The recent wildfires in the greater Los Angeles area call attention to the risks to people and property in urban areas. We hosted a Climate Conversation to highlight the lessons learned and opportunities for science to support impacted communities, drawing on experience from other major urban fires in the last few years. The event unpacked the range of factors that are contributing to urban wildfire risk, and explored the impacts on health, infrastructure, and other human systems, as well as discussed how communities can prepare and move forward in the aftermath of a disaster. Climate Conversations: Pathways to Action is a monthly webinar series from the National Academies of Sciences, Engineering, and Medicine that aims to convene high-level, cross-cutting, nonpartisan conversations about issues relevant to policy action on climate change. Participant Bios Michael Méndez is an assistant professor of environmental policy and planning at the University of California, Irvine and Visiting Scientist at the National Center for Atmospheric Research (through a National Science Foundation Early Faculty Career Award). His first book “Climate Change from the Streets,” published through Yale University Press (2020) was the winner of the Harold and Margaret Sprout Award, given to the best book in the field of international environmental studies and politics

Parallel evolution is the independent evolution of similar traits, starting from a similar ancestral condition. Frequently this is the situation in more closely related lineages, where several species respond to similar challenges in a similar way. One of the most spectacular examples of parallel evolution is provided by the two main branches of the mammals, the placentals and marsupials, which have followed independent evolutionary pathways following the break-up of land-masses such as Gondwanaland roughly 100 million years ago. In South America, marsupials and placentals shared the ecosystem (prior to the Great American Interchange); in Australia, marsupials prevailed; and in the Old World the placentals won out. However, in all these localities mammals were small and filled only limited places in the ecosystem until the mass extinction of dinosaurs forty million years later. At this time, mammals on all three landmasses began to take on a much wider variety of forms and roles. While some forms were unique to each environment, surprisingly similar animals have often emerged in two or three of the separated continents. Examples of these include the litopterns and horses, whose legs are difficult to distinguish; the European sabre-tooth tiger (Smilodon) and the South American marsupial sabre-tooth (Thylacosmilus); the Tasmanian wolf and the European wolf; likewise marsupial and placental moles, flying squirrels, and (arguably) mice.
