This 'Limit' Breathed Its Last Sometime Ago?

The UN head, Antonio Guterres, says that the goal of limiting global heating to 1.5 degrees Centigrade (above pre-Industrial levels) is "gasping for breath" (https://www.theguardian.com/environment/2022/dec/19/climate-goal-15c-gasping-breath-un-head-antonio-guterres). Guterres opines that there is an urgent need to accelerate the rate of change in 'greenhouse gas' emissions. He does have to try to maintain the somewhat arbitrary 'limit' advocated in Paris but a) It's by no means certain that 1.5 is 'safe' and b) all the indications are that it breathed its last, sometime ago!
