.ON FEBRUARY 8TH the Copernicus Climate Change Service, an EU agency, declared that in the one year to January 31st the world's temperature level had been actually, generally, 1.52 u00b0 C greater than pre-industrial levels. The Paris arrangement, a temperature treaty of 2015, fully commited nations to always keep the growth in "worldwide standard temp ... properly below 2 u00b0 C over pre-industrial levels" and find to limit it to 1.5 u00b0 C. Can people point out that the planet has gone beyond one of the Paris milestones? If it has not, what would be actually needed to make such a claim?
