Texas prisons do not have air conditioning despite record-setting heat 6 months each year. Until recently, few have cared outside the prison family circles. Now, though, with a renewed interest in prison architecture, prison sentencing, prison solitary, prison abuse of juveniles and the mentally ill--now inmate problems have attracted the attention and study of academics who are joining in the national cry to fix prison conditions. A major step forward is the paper just published by Colombia Law School visiting scholar Daniel Holt. Heat in U.S. Prisons and Jails: Corrections and the Challenge of Climate Change traces the problems caused by both rising temperatures and lower interest in prison populations.
