Getting Warmer?

A Professor from the UK Meteorological Unit has suggested, to the UN Climate Conference in Poland, that we should talk about 'global heating' rather than 'global warming' (https://www.theguardian.com/environment/2018/dec/13/global-heating-more-accurate-to-describe-risks-to-planet-says-key-scientist). This certainly makes sense in terms of the physics but, I suspect, that 'warming' was used, as the actual magnitude of the change is slight. 'Slight', however, does not mean without substantial consequences for the planet and its surface dwellers.
