 Well that concludes the 4th week of Denial 101X. This week we look back into the past and peered into the future. Peter Jacobs and Robert Way took us on a tour of Earth's history, going back millions of years and looking at climate in medieval times and in the 1800s. Daniel Bedford, Dana Nietzsche-Towey and Kier Shahneman examined climate models and how they are able to simulate future climate change. Our interviews featured paleo-climatologists and climate modelers, and of course part one of the climate of Midland. Next week we look at the impacts of climate change. Kier Shahneman, Dana Nietzsche-Towey and Peter Jacobs look at how sensitive our climate is to increasing greenhouse gases. Dana Nietzsche-Towey will look at just some of the ways that climate change is affecting the environment and society. And Ove Haagelberg will explain how our oceans are becoming more acidic and how this affects coral reefs. We'll also talk to a number of scientists researching the impacts of climate change. Christine Hosking is a researcher at the University of Queensland who has published research into the impacts of climate change on koalas. This is a fascinating interview, although Pistachio the koala can be a little distracting. We also spoke to Sir David Attenborough at Heron Island in the Great Barrier Reef. You'll get to see the full interview next week. And yes, we'll also have the second installment of the Climate of Midlife. We hope you enjoyed the fourth week of Denial 101x. As always, we'd love to hear what you learned this week, any questions you have and your thoughts about next week on the weekly Wrap Up Discussion Forum. Next week's topic is climate impacts. The Wrap Up Discussion Forum is where you can find out what your fellow students think about this week's topics and also see what's going on in their part of the world related to climate change. So we look forward to seeing you again next week.
