On Monday night, Dick Whitaker, former meteorologist for the Bureau of Meteorology, The Weather Channel and Sky News Weather and author of books such as The Complete Book of Australian Weather, Understanding Climate Change and Australia’s Natural Disasters explained the current research into Climate Science. Over 150 students, teachers and parents from a variety of schools were able to learn that the six main drivers of global temperature include (1) solar irradiance, (2) Milankovitch cycles, (3) extra terrestrial (meteorite) interaction, (4) continental drift, (5) atmospheric aerosols, and (6) the chemical composition of the atmosphere. Dick shared the current theories about which of these factors were responsible for various notable events of the past including ice ages, species extinction, the medieval warm period, and the current warming since 1980.

Dick concluded the night with a plea for Australians to keep investigating the explanatory and predictive power of science and for that to result in Australians to “trust science”.

Science at Barker is a popular subject and through events like this particular evening, and through classroom teaching we hope to demonstrate how a deeper understating of the science can lead to more informed decisions about a topical and difficult issue.

Over 50 Year 12 students studying Earth and Environmental Science were in attendance from Barker and neighbouring schools, along with a number of Earth and Environmental teachers, as this talk closely aligned with the Year 12 syllabus. It was an excellent opportunity for students to experience a university-style lecture from a renowned expert where they could continue their learning outside the classroom alongside staff, parents and community members.
