Today marks the start of the three-day Aspen Ideas: Climate Summit in Miami Beach. Spokesman Greg Gershuny says they're expecting two-thousand guests, two hundred speakers and fifty sessions focused on finding solutions for climate change. Miami-Dade Mayor Daniella Levine Cava is one of forty mayors on hand highlighting the new Priority Climate Action Plan (PCAP) submitted this month. It serves as a regional greenhouse gas emissions reduction plan, which will reduce air pollution and ultimately energy bills.
