On November 12, 2015, DfRR brought together an amazing group of speakers representing the broadest cross-section of professions involved in climate change to highlight both the short and long-term impacts of extreme heat and the risks we take if we fail to act. The committee organized panels and case studies in terms of scale, from the most global challenges to the most local opportunities. Conflicting and contrasting solutions were welcome, making for an oftentimes lively debate. The symposium also illuminated the unresolved and the yet-to-be-determined.
