Some feel it’s happening, but can’t decide if it’s a natural cycle or caused by humans.

Others feel it may be a little of both or not happening at all.

If you want to learn more about the topic, researchers from around the world have created a free online course through the University of Queensland.

It’s called a Massive Open Online Course, or MOOC.

The class will explore why the topic of climate change is so controversial and hopes to explode a number of climate myths along the way.

It’s being taught by several renowned researchers from universities in Canada, the United States and the United Kingdom, including Dr. Keah Schuenemann, Assistant Professor of Meteorology at Metropolitan State University in Denver.

University of Queensland’s John Cook says the course will tackle climate myths and expose techniques that are often used to mislead the public.

“This free course explains why there is such a huge gap between the scientific community and the public,” said Cook.

The course, Making Sense of Climate Science Denial, features interviews with 75 notable scientific experts.

It incorporates climate science and the psychology of climate change to explain the most common climate myths and to detail how to respond to them.

“This isn’t just a climate MOOC. It’s a MOOC about how people think about climate change,” Cook said.

The seven-week course begins on April 28 and thousands of students from more than 130 countries have already enrolled.
