Businesses and investors increasingly require such data. A California climate risk advisory group issued a report Monday that recommends the state ensure everyone have access to climate data and technical help using it. The Probable Futures tool might help, said co-author Alicia Seiger, managing director of Stanford University’s Steyer-Taylor Center for Energy Policy and Finance.

As governments and companies build infrastructure for hotter times, everyone must know what conditions may be like, and mapping tools may increasingly be seen as necessary public infrastructure. Probable Futures expects to make parts of its tool publicly accessible so that people and organizations can customize maps.

“The need for technical assistance is huge,” Seiger said. “This level of information can be plenty for the kind of decision-making that’s required.”
