California Prison System Beginning $38M Pilot Project to Test Ways to Keep Cells Cooler at 3 Prisons
California's $38 million pilot program will test air conditioning and insulation at three prisons to reduce cell temperatures to 78 degrees amid rising summer heat risks.
- On July 4–5, Adrienne Boulware, incarcerated woman at Chowchilla State Prison, collapsed during a heat event and died after hospital transfer with a body temperature of 41.5°C.
- At Chowchilla, repeated triple‑digit heat has meant incarcerated women at Chowchilla prison repeatedly endure hot cells, using showers and fans as last summer recorded 28 days ≥105°F amid rising climate change risks.
- The corrections department launched a $38 million pilot program this year to reduce temperatures to 78 degrees at three prisons, while a court-ordered summer heat protocol requires daily temperature logs and staged responses at 90°F and 95°F.
- Legislative momentum stalled after cost estimates of $10 billion to $20 billion prompted Assemblymember Celeste Rodriguez to hold a bill requiring cooling and monitoring, while federal class-action plaintiffs pressed heat issues and U.S. District Judge Jon S. Tigar ordered CDCR to provide data.
- Court monitors found persistent gaps in protocol implementation, noting staff unaware of rules and broken thermometers, while last year 46 days exceeded 95°F, disrupting therapy and recreation across CDCR facilities.
