On Saturday the City of Tucson, Arizona, is bringing its citizens together to discuss the challenges climate change poses for the city and the opportunities to respond. "As an Arizonan and former Governor, I’m proud to see the City of Tucson take up the challenge to prepare for these serious changes and work with the public on solutions," says former Arizona Governor, Bruce Babbitt.  "These are big challenges, but they are ones we can overcome...The first step is to look the problem square in the eye, rather than bury our heads in the sand; the second is to prepare for the impacts." 

“In an increasingly urbanized world, global sustainability in the context of a changing climate will depend on achieving sustainable and climate resilient cities,” the Intergovernmental Panel on Climate Change (IPCC) says today (28 March 2012).  Cities are increasingly experiencing the disruptive and costly impacts of changes in the frequency and/or severity of weather extremes.  Responding to the trends, city officials are engaging their citizens in efforts to build more resilient, better prepared and more sustainable communities. On Saturday the City of Tucson, Arizona, is bringing its citizens together to discuss the challenges climate change poses the city and the opportunities to respond.  At the event, WWF will launch its Earth Hour City Challenge to encourage cities across the country to similarly engage their citizens around climate impacts and preparedness.
