On Steinman et al. (2015) – Michael Mann and Company Redefine Multidecadal Variability And Wind Up Illustrating Climate Model Failings

Guest Post By Bob Tisdale For the past few years, we’ve been showing in numerous blog posts that the observed multidecadal variations in sea surface temperatures of the North Atlantic (known as the Atlantic Multidecadal Oscillation) are not represented by the forced components of the climate models stored in the CMIP5 archive (which were used…

Roger Pielke, Jr. Being Investigated by Representative Grijalva for Presenting Inconvenient Data

Guest Post by Bob Tisdale Roger Pielke, Jr. is not a skeptic of human-induced global warming, as we all know.  Pielke Jr. is being investigated, however, for the “crime” of presenting data that disagree with alarmists who make bogus claims about weather and weather-related losses. See Roger’s post I am under “Investigation”, in which he…

New Paper Confirms the Hiatus Is Not Occurring at the Poles, Undermining the Efforts of Cowtan and Way

Guest Post by Bob Tisdale Pierre Gosselin of NoTrickZone reports on a paper that confirms the slowdown in global surface warming has not been occurring at the poles. See Pierre’s post German Experts: New Paper By Gleisner Shows 2013 Cowtan And Way Arctic Data Hole Paper Was A Lemon. You’ll recall that Cowtan and Way…

Climate Propaganda from the Australian Academy of Science

Guest Post by Bob Tisdale The Australia Academy of Science has recently published a Q&A about human-induced global warming titled The science of climate change.  Their press release is here.  Examples from around the blogosphere: Andrew Montford discussed it briefly in his post The Oz guide to climate change at BishopHill. The Australian published the article…

January 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

Guest Post by Bob Tisdale This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through January 2015 and HADCRUT4 and NCDC through December 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through January 2015. INITIAL NOTES: For discussions of…

Recent Paper Ends Abstract with “…Model Might Be Too Sensitive to the Prescribed Radiative Forcings”

Guest Post by Bob Tisdale The paper is Douville et al. (2015) The recent global warming hiatus: What is the role of Pacific variability? [paywalled].    The abstract reads (my boldface): The observed global mean surface air temperature (GMST) has not risen over the last 15 years, spurring outbreaks of skepticism regarding the nature of global…
