The current rate of temperature and atmospheric carbon dioxide increase is almost unprecedented in Earth’s entire 4.5-billion-year geological history. The only other time global temperatures and conditions changed this dramatically was when an asteroid hit the Earth 66 million years ago, famously triggering an age of mass extinction and a rapid increase of 5 °C in global temperatures that lasted for roughly 100,000 years.
The Council of the Royal Society of Victoria is delighted to announce that Professor Patrick De Deckker AM has been selected to receive the RSV’s 2023 Medal for Excellence in Scientific Research. Patrick’s remarkable career spans almost three decades, making enormous contributions to fields within palaeoontology and environmental science.
From remote Antarctica to the towering Himalayas, accelerating ice loss under climate change casts a stark shadow over ecosystems, coastlines, and the equilibrium of our global environment. Glaciologists like Professor Andrew Mackintosh work to understand past glacier and ice sheet changes to improve future predictions – and that future looks bleak.
Australia had installed more renewable generation infrastructure in the three years leading up to 2020 than the thirty years prior. While these are positive steps, Australia also has the highest per-capita greenhouse gas emissions of any other advanced economy, and is nowhere near close to reaching its Paris Agreement goals. Victoria’s Gas Substitution Roadmap is a step in the right direction.
A significant, urgent and sustained reduction in emissions is required to reach greenhouse gas neutrality by 2050. A target of 50% reduction relative to 2005 levels by 2030 for Australia would be consistent with the required rate of emissions reductions to meet the Paris Agreement targets of limiting global warming to less than 2°C above pre-industrial levels.
