GLOBAL TEMPERATURE INCREASING AT ONLY 1C PER CENTURY,NEW PAPER SAYS

This new paper claims that the true figure for  the rise in global temperature is much less than has been estimated by computer climate models.  The authors, including John Christy, identify and remove the main natural perturbations (e.g. volcanic activity, ENSOs) from the global mean lower tropospheric temperatures (T LT ) over January 1979 – June 2017 to estimate the underlying, potentially human-forced trend. The unaltered value is +0.155 K decade − 1 while the adjusted trend is +0.096 K decade − 1 , related primarily to the removal of volcanic cooling in the early part of the record. This is essentially the same value they determined in 1994 (+0.09 K decade − 1) using only 15 years of data.
