Heat and humidity are to blame for the early release of students at Baltimore schools by county officials for the second day in a row, according to Sport Act. In addition, all after-school programs, practices and sporting events have been shut down. About 52 schools across the county do not have air conditioning, but all were closed early in uniformity against the increasing heat.

The classrooms get full sun with windows open and no air conditioning. Teri Chason is one of the frustrated Carney Elementary parents, according to CBS Baltimore. "It's not safe for the kids," Chason said. "The kids come home, they're nearly sick."

When the temperatures hit the 90s on Tuesday, schools were let out two hours early due to the unbearable conditions. "I grew up in the 80s. I never had air in school, and I remember how miserable that was. So I think we can be understanding," said one parent.

Complaints are not uncommon from teachers, students and parents regarding the lack of air conditioning; 30 percent of schools in the Baltimore County School District are without air conditioning, according to The Baltimore Sun. Parents also took to social media to complain about the air conditioning deficit last week, as the temperatures sky rocketed.

A county schools air conditioning renovation schedule is already planned and stretched out over the next six years, with a goal of 99 percent of the schools to have air conditioning after six years.

The National Weather Center is forecasting more moderate temperatures for Thursday, with highs expected to be in the upper 70s.
