Has Mann become climate change "denier" now? Hardly.Ībout the new study, Nature News reports: The evidence presented here contradicts these claims. It has been claimed that the early-2000s global warming slowdown or hiatus, characterized by a reduced rate of global surface warming, has been overstated, lacks sound scientific basis, or is unsupported by observations. Mann is now a co-author on the new study that pulls that stake out: I expect this article will be attacked by climate change deniers who are unhappy to see the demise of a narrative they helped frame, a narrative that arguably took hold due in part to the "seepage" of contrarian framing into mainstream climate science discourse. ![]() Just out in Science is a new article by Tom Karl of NOAA's National Climatic Data Center and colleagues driving another stake through the heart of the supposed "hiatus" or "pause," i.e. Interestingly, it includes as co-authors some of the more prominent climate researchers who have challenged the notion of the "pause." For example, last June, Pennsylvania State University climatologist Michael Mann crowed: Now a group of climate researchers in Nature Climate Change have published an article, " Making sense of the early-2000s warming," that argues the hiatus is real and not well understood. That study eliminated the hiatus by controversially adjusting ocean temperature data derived from robot buoys to match earlier data temperature data taken by ocean-going ships. ![]() ![]() One of the more heralded studies was published by researchers associated with the National Oceanic and Atmospheric Administration (NOAA) in June, 2015. There have been scores of studies that have tried to explain away this inconvenient fact. Lots of climate researchers and climate change activists have been discombobulated by the fact that global average temperature increases have been considerably slower during the first years of this century than most climate models projected.
