It has been long understood that climate change will affect some regions more severely than others. However, quantifying these differences in a consistent way across many indicators of climate change has proven difficult in the past, mainly due to differences in how these metrics of climate change are defined.

Lead author Dr Luke Harrington, a Postdoctoral Research Associate at the ECI, explains: "Our paper takes a different approach, by looking at what changes are expected for one specific region after a certain amount of global warming, such as the Paris Agreement's 1.5°C threshold above pre-industrial levels. We then use climate models to identify how much global temperatures need to rise for different locations around the world to experience an equivalent level of change. This is what we refer to as the Temperature of Equivalence Index."

Illustration - Framework - Authors - Changes - Severity

As an illustration of the framework, the authors find changes to the severity of extreme heat events for low-income nations after 1.5°C of global warming would not be seen for regions of the world with high-income populations until after a global temperature rise twice as high. 'Our example of low-income nations experiencing more extreme heat earlier than their high-income counterparts is already well-known within the scientific community," says co-author Dr Andrew King, from the University...
