“Silver Buckshot” for Energy Transition

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.

The Royal Society of Victoria – Official Position on Climate Change

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.

Greenhouse in Australia, 50 Years On

It had been known for more than hundred years that increases in concentration were likely to warm the planet. So CSIRO commenced work on the modelling of the whole climate system. But in the 1980s it was realised that very few of our Australian colleagues, across a wide range of different disciplines, were either aware of the potential of global warming, or seriously considering, from their own perspectives, whether it was of any importance.

Coastal Resilience: Shifting Sands and Battered Beaches

Our sea levels are rising. Understanding the dynamics of the beach envelope and its overlap with human infrastructure is fundamental for effective coastal management. Dr David Kennedy studies the dynamic adaptation of beaches in the past to inform how we can manage them into the future. While NSW beaches have been studied for decades, but we are only just starting to understand the behaviours of Victoria’s beaches and their underlying geology.

Anthropocene Now

The term “Anthropocene” was first used 20 years ago to describe a new epoch of geological time, coinciding with the start of the Industrial Revolution around 1750. It indicates a transition out of the Holocene into a new age – the age of human impact. This term has incited great debate amongst the scientific community as, in order for a new new geologic epoch to be accepted, we need to demonstrate our impact on the rock strata around and beneath us. This was achieved in 2019.
