Human activities have released significant quantities of carbon dioxide into the atmosphere. As a greenhouse gas, the more carbon dioxide emitted, the warmer our planet becomes. Partly mitigating these impacts, plants recover 30% of atmospheric carbon via photosynthesis. Using energy from the Sun, they combine carbon dioxide with water to form sugar and oxygen. When the chemical reaction is reversed, carbon returns to the atmosphere – either by cellular respiration in plants and animals, or the burning of coal, wood, or gasoline. Soil scientist Dr Samantha Grover explains that one way of preventing carbon dioxide from returning to the atmosphere is keeping it sequestered in the ground. In fact, there is two-to-three times more carbon in soil than in the atmosphere.
Senior Climatologist Dr Lynette Bettio explains that soon we will no longer be considering how we get through a single intense year, such as 2019, but how we can make it through a stretch of years with no respite. The climate has been set on a warming path – the long-lived greenhouse gasses that are in the atmosphere and the extra energy soaked up by oceans have secured the warming trend continuing for the next few decades. So the Bureau of Meteorology and CSIRO are investing a lot of effort to solve these problems, knowing the sooner we take action, the sooner we will see a divergence from the alarming projections in current climate models and simulations.
With electric vehicles predicted to represent 90% of all cars and light commercial vehicles on Australian roads by 2050, structural supercapacitors have the potential to revolutionise our transport by providing ‘mass-less’ energy storage, storing electrical energy in lightweight structural components of a vehicle’s body instead of in heavy, sole-purpose batteries. Dr Nisa Salim and her research team are working with multinational companies and Australian SMEs to demonstrate the exciting potential of these new supercapacitors, leveraging her collaborative relationships with a global academic and industrial network to take this cutting-edge research from the lab to the market place.
According to Dr Anita Hill, CSIRO’s Chief Research Scientist, “There are several impressive factors about Professor Fox. Her ability to communicate, inspire, and advocate for science is evident not only from the ecosystem that she has been able to create and fund but also from her presentations, several of which are available on YouTube as TEDx talks or interviews. She provides audiences of any background a vision of the future and one where Australia is designing and manufacturing the lightweight materials of future mobility (flying cars, hyperloops). She is a role model for STEM and for supporting high tech companies in Australia. She is recognised internationally, and uses her networks to Australia’s advantage.”
A multi-disciplinary panel gathered to discuss what they see as inspirational for scientists, governments and communities to take action in response to COVID-19, devastating bushfires, and systemic racism and social unrest. Before the pandemic we were amongst the unbridled fires, lush landscapes were blistering, and communities came together to offer donations and support to rebuild towns that were destroyed. During the pandemic and in lockdown we feel as if we’re in a snow dome. Gaps in wealth, age, sex, age and disability became highlighted and people marched forcefully with thunder in response to social injustice. Once we emerge, we hope to have better communication with scientists and vigorously carve out a new equilibrium.
