Although Australia has some of the world’s leading renewable energy sources, we are on a standstill on the climate change issue, well behind our major trading partners like the US, UK, China and Europe who are already taking action to reduce emissions. The Climate Commission’s inaugural report has called Australia to scale up its emissions-reduction targets to a 75% cut by 2030, which sounds daunting, but is achievable. It has been anticipated that it will be impossible to keep our temperatures below 1.5C – should we cross any higher we will be at risk of irreversible changes to the global climate system like collapse of ice sheets and the destruction of critical ecosystems. Will Steffen, Executive director of the Australian National University Climate Change Institute joined us earlier to discuss.
