Watch out for Mr. Linnartz, a science teacher who is a climate denier. He does not acknowledge basic science of CO2, greenhouse gas emissions & global warming. His classroom "preachings" & "politcal ramblings" are allowed to go on and on and students fear retaliation from Mr. Linnartz. Students who want to learn about science need to steer clear of this guy. He is known to get in students' faces and scream at them. His small-minded "anti-science" views totally cloud any ability he has for teaching. Very disappointing behavior for a "science teacher".
