The IPCC aims to understand the influences driving the Earth’s climate variability and future climate scenarios. It does not conduct its own research or run models; instead, it provides a meta-analysis of the work of thousands of researchers across the globe to provide a scientific basis for governments to develop climate-related policies. The IPCC warns of risks to food production and security, water availability, species extinction, biodiversity reduction, coastal erosion, floods and droughts, negative impacts on human health, and population displacement. ‘The IPCC has been saying the same thing since the 1990s, but no one is listening,’ said Dr Chloe Mackallah, reading directly from the IPCC’s Fifth Assessment Report, which states that the effects of anthropogenic greenhouse gas emissions ‘are extremely likely to have been the dominant cause of the observed warming since the mid-20th century.’
The official position of the Royal Society of Victoria is that, given the irrefutable scientific evidence for human activity driving climate change, it is vital that policies that curb greenhouse gas emissions from all sources be developed and implemented as a matter of urgency on a global basis. For Australia, this would mean the encouragement of the development of renewable sources of power, such as solar and wind generation with appropriate methods of storage, the improvement of energy efficiency, and to encourage the consumers of Australian coal (mostly Japan, Korea, India and China) to adopt similar policies.
