eBooks by Bob Tisdale

Sales of my ebooks (and tips) allow me to continue my research into human-induced and natural climate change and to continue to blog here at Climate Observations and at WattsUpWithThat?

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

UPDATE: I’ve changed the title. This better represents the post.

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 by the IPCC for their 5^th Assessment Report).  We’ve done this by using the Trenberth and Shea (2006) method of determining the Atlantic Multidecadal Oscillation, in which global sea surface temperature anomalies (60S-60N) are subtracted from the sea surface temperature anomalies of the North Atlantic (0-60N, 80W-0).  As shown in Figure 1, sea surface temperature data show multidecadal variations in the North Atlantic above and beyond those of the global data, while the climate model outputs, represented by the multi-model mean of the models stored in the CMIP5 archive, do not. (See the post here regarding the use of the multi-model mean.)  We’ll continue to use the North Atlantic as an example throughout this post for simplicity sake.

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

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 discusses the investigation by US Representative Raúl Grijalva (D-AZ), the ranking member of the House of Representatives Committee on Environment and Natural Resources.  Pielke, Jr.’s “crime”:

Quick Mid-February 2015 Equatorial Pacific Sea Surface Temperature Anomaly Update

UPDATE:  Fixed the typo in the headline. [Thanks, Miguel Alarcon.]

Just a quick look at the weekly sea surface temperature anomalies of the 4 most-often-used NINO regions of the equatorial Pacific. From west to east they include:

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

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.

Climate Propaganda from the Australian Academy of Science

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:

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

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.

New Paper: Unprecedented 21st-century drought risk in the American Southwest and Central Plains

That’s the title of a new paper by Cook et al. that’s been making the rounds in the mainstream media.

The paper is available from GISS here. The abstract reads:

January 2015 Sea Surface Temperature (SST) Anomaly Update

INITIAL NOTES

Note 1: The NOAA NOMADS servers are still off line.  NOAA replied to my email inquiry and advised that the NOMADS website will be down for an extended time period and there were no estimates for when they would be returned to service.

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

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):

Many Mixed Signals in the UKMO’s Latest 5-Year Global Surface Temperature Forecast

The UKMO issued their most recent 5-year global temperature forecast about a week ago. See their Decadal forecast press release for 2015.  It has been getting a little press recently.   The forecast description wasn’t as clear as it could have been, but the UKMO openly displayed the failure of the forecast from 2009 sea surface temperatures.
