The Super Sixes: Rachel Warren, Jareth Holt, Shuchi Talati, Lan Hoang, Katie Loa, Casey Hagelson

ROAD MAP

Problem Objective & Stakeholders Work Plan Mock Event Tree

PROBLEM

Compound risk of multiple coinciding extreme events result in increased risk of heat-related illnesses, increased risk of peak energy demand, increased risk of power outages, etc.

How should decision-makers (public health officials, power sector, government officials) plan for these events in the short and long-term?

OBJECTIVE

To assess and present a framework for low probability, high heat-related impacts of climate change on Clark County and potential alternatives to address these impacts

Stakeholder: City of Las Vegas

Deliverable: White paper

WORK PLAN (1)

Split into 2 groups (climate events and impacts & alternatives group)

Climate group: Current probabilities Future probabilities Indicators & forecasting

Impacts group: Inherent vulnerabilities Range of potential alternatives Cost assessments
