As GIS practitioners we face many different challenges, and those brought on by climate change are among them. Though some aspects of climate change are still controversial, the facts are that climate change is real, it's happening, and it's something that we have to deal with—now. We're seeing the effects of climate change manifested in many ways, and these present significant challenges for being prepared, responding, and mitigating these effects.
But using a GIS-based approach, and leveraging new tools and capabilities, we're in a better position than ever before to understand, predict, and deal with these changes. At the Esri 2014 User Conference climate change framed the afternoon plenary session, and this recent Esri Insider blog post summarizes the essential GIS building blocks for resilience.
