>Ever since Scafetta and West, in their recent paper “Is Climate Sensitive to Solar Variability?”, March 2008 “Physics Today”, provided the graph of Phenomenological Solar Signal (PSS) from 1950 to 2007, I’ve wanted to see what effect adding other natural … Continue reading →

>As discussed in my previous post, “Annual and Long-Term Impacts of El Nino/Southern Oscillation (ENSO)”, the global temperature anomaly curve, the backbone of the AGW movement, is simply a running total of annual variations in global temperature. Applying this same … Continue reading →

>Keep in mind when reading this post that the NINO3.4 temperatures shown in many of the graphs have been scaled drastically; the changes in NINO3.4 temperature are, in fact, more than 10 times greater than illustrated. Also keep in mind … Continue reading →

>Figure 1 provides a comparison of GISTemp smoothing radius data for January, 1978 through April, 2008: the blue curve with 250km radius smoothing, the red with 1200km.http://i26.tinypic.com/jp9a88.jpgFigure 1: GISTEMP Smoothing Radius Comparison – 250km (Blue) vs 1200km (Red) – January, … Continue reading →

>The majority of ENSO SST-based data available online is anomaly data that has been normalized, standardized, smoothed, filtered, or combined with other variables. I went searching for and found what I believe to be unadulterated NINO 3.4 SST data. It’s … Continue reading →

>Update: I was advised yesterday, May 16th, that JunkScience corrected the errors described in the following. In the text of the first part of this series, I wrote that I originally downloaded the .csv files from JunkScience. I have not … Continue reading →

>Please refer to the notes on data source prior to downloading the JunkScience .csv files.http://bobtisdale.blogspot.com/2008/05/fresk-look-at-ncdc-absolute-data-source.html GLOBAL LAND TEMPERATURE In my view, I saved the best for last. Figure 3.1 illustrates the large span of annual global Land Surface Temperature (LST) … Continue reading →

>Please refer to the notes on data source prior to downloading the JunkScience .csv files.http://bobtisdale.blogspot.com/2008/05/fresk-look-at-ncdc-absolute-data-source.html GLOBAL OCEAN In Part 1 of this series, the magnitude of the variations in Land Surface Temperature (LST) overwhelmed Sea Surface Temperature (SST), making SST … Continue reading →

>Please refer to the notes on data source prior to downloading the JunkScience .csv files.http://bobtisdale.blogspot.com/2008/05/fresk-look-at-ncdc-absolute-data-source.html OVERVIEW Like many people, I’ve examined temperature anomaly data and reexamined it until it seems to offer no new climate insight. NCDC Absolute data (Courtesy … Continue reading →

> WHY A RUNNING TOTAL? If the intensity and frequency of El Nino and La Nina events were equal, they would balance one another, and a running total would hover near zero. Example:Annual Nino3.4 Values = +2, -1.5, +1.0, -1.5Annual … Continue reading →
