From heat vulnerability mapping to community heat kits, we combine data-driven research with grassroots action to protect those most at risk from extreme heat in Southern California.
We built THRIVE, a heat vulnerability app that maps urban heat islands across the Inland Empire — where the same region can be 10–15°F hotter due to differences in tree cover, pavement, and roofing. Our work was selected for the Congressional App Challenge and the President's AI Challenge, and is mentored by USC and Children's Hospital Los Angeles.

We've distributed hundreds of kits so far, and we've planted 10 oak trees in Chino Hills to build cooler, more resilient communities long-term.
Get involved →Extreme heat is the leading environmental cause of mortality in the US — yet it rarely receives the emergency response it deserves. We use data from THRIVE to advocate for targeted investments in tree canopy, shade, hydration stations, and cooling centers in the neighborhoods that need them most.
