Although the human responses to climate change are volatile, the laws of Physics are not. Since the 1905 Chemistry Noble laureate Svante Arrhenius first modelled the greenhouse effect on the temperature of our planet little has changed from his prediction of a 2.1 degree Celsius temperature rise for a doubling of the 1905 carbon dioxide levels in the atmosphere. Today, with greatly improved physical models, the prediction is between 2 and 4.5 degrees under the same scenario. Physics helps us understand the past, present and future scenarios for the climate of our planet. Working out what to do about our emissions and climate change requires us to look at our present and future energy budget. But it is power that drives our civilisation, not energy. The paths from energy to power are constrained by the unbreakable laws of entropy. This lecture explains entropy and the big challenges involved in charting the uncertain future.

The Bronze Bragg medal and merit certificates will be presented at the lecture. The medal is awarded for the best performance in 2016 in Physics in the Stage 2 SACE assessments, with certificates being for students who achieved a merit.
The presentation and lecture will be held in the Napier 102 Lecture Theatre, Napier Building, 1st floor, University of Adelaide, North Terrace, north from Pulteney St., at 6.30pm. Members of the public are warmly invited to attend. We are obliged for security reasons to keep the front door of the building attended, so please arrive before 6.30pm. Bookings are not available.
