Global heating is a term adopted to communicate the seriousness of the climate crisis and the urgent need to address it. According to Professor Richard Betts from the UK Met Office, a leading climate change specialist, the term is also more accurate than global warming. While ‘warming’ relates to changes in temperature, ‘heating’ reflects energy flows (heat is energy). Human actions that increase the concentration of greenhouse gases (GHGs) in the atmosphere do in fact change the energy flows between the Earth and space.
