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.
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.’
