The Australian National University has received a lot of hate mail and abusive language directed at some of its scientists.
Some of the scientists have been moved to safety.
Vice-Chancellor of the Australian National University, Professor Ian Young, said that employees do not have to put up with this behavior.
"Obviously, climate research is an emotional issue at the moment, but the issues on which we need to have a peaceful public debate, not death threats," said Professor ABC News 24.
"In fact, it is absolutely unacceptable that people are exposed to this kind of abuse and threats like this."
