How to recognize when the world has passed 1.5 u00b0 C of global warming

.ON FEBRUARY 8TH the Copernicus Weather Improvement Service, an EU company, declared that in the one year to January 31st the globe’s temp had been, usually, 1.52 u00b0 C higher than pre-industrial degrees. The Paris contract, a weather treaty of 2015, focused countries to always keep the rise in “international standard temperature level … properly below 2 u00b0 C above pre-industrial degrees” and also seek to confine it to 1.5 u00b0 C.

Can people claim that the world has surpassed one of the Paris landmarks? If it has not, what would certainly be needed to make such a case?
