But how much can wind farms and solar panels contribute to a solution? Are they really the best option for Australia's energy future? And what part does the media play in the communication of all of this? The Science behind the headlines event (22 May 2012) held by RiAus attempted to answer these questions by combining a panel of scientists with experienced journalists - led by RiAus Programs Co-ordinator James Byrne. Each of the participants' knowledge of their specific field made for a varied and vibrant discussion that covered a wide range of topics. Is the public really aware of alternative energy options?

Last week the world's atmosphere took a giant leap backward. For the first time in more than 3 million years, the atmospheric concentration of carbon dioxide (CO2) reached 400 parts per million. This was recorded at the National Oceanic & Atmospheric Administration's Earth System Research Laboratory located on Mauna Loa in Hawaii right out in the middle of the Pacific Ocean, a long way from major sources of CO2 in Asia and North America. What this means for the environment is uncertain but it's likely that, if no measures are taken to reduce this level of greenhouse gas, we could be headed for 3-4 degrees C warming globally by the end of this century
