Given the decadal averages and the issue of what is meant by «the next» decade, Romm does have a point that the result of the paper could more clearly be described as representing «a period of flat global mean temperatures extending somewhat into the coming decade, following by a very rapid rise in temperature leaving the planet on its long - term trend line by 2030.»
