Robots Recreating Past Temperatures – Are Best to Avoid Australian Data

Reposted from Jennifer Marohasy’s Blog May 17, 2019 By jennifer At an artificial intelligence (AI) conference in New York recently, Sean Gourley explained Wiener’s Law: automation will routinely tidy up ordinary messes but will occasionally create an extraordinary mess – that so mimics what could have been, that the line between what is real, and…

Willis’ Favorite Airport

By Steven Mosher, AC Osborn made an interesting comment about airports that will give me an opportunity to do two things: Pay tribute to Willis for inspiring me and give you all a few more details about airports and GHCN v4 stations. Think of this as a brief but necessary sideline before returning to the…

Australia Surface Temperatures Compared to UAH Satellite Data Over the Last 40 Years

Reposted from Dr. Roy Spencer’s Blog April 3rd, 2019 by Roy W. Spencer, Ph. D. Summary: The monthly anomalies in Australia-average surface versus satellite deep-layer lower-tropospheric temperatures correlate at 0.70 (with a 0.57 deg. C standard deviation of their difference), increasing to 0.80 correlation (with a 0.48 deg. C standard deviation of their difference) after…

A condensed version of a paper entitled: “Violating Nyquist: Another Source of Significant Error in the Instrumental Temperature Record”.

By William Ward, 1/01/2019 The 4,900-word paper can be downloaded here: https://wattsupwiththat.com/wp-content/uploads/2019/01/Violating-Nyquist-Instrumental-Record-20190112-1Full.pdf The 169-year long instrumental temperature record is built upon 2 measurements taken daily at each monitoring station, specifically the maximum temperature (Tmax) and the minimum temperature (Tmin). These daily readings are then averaged to calculate the daily mean temperature as Tmean = (Tmax+Tmin)/2. Tmax…

How to NOT find a slowdown

Sheldon Walker – (agree-to-disagree.com) The slowdown/pause/hiatus, would probably be only a dim memory, if Alarmists didn’t keep digging up the imaginary corpse, in order to show that it really is dead. The website called “The Conversation”, recently featured an article called “Global warming ‘hiatus’ is the climate change myth that refuses to die”, by Stephan…

Gulf Summers Aren’t Global Averages: A Reply to Farron Cousins

Alan Reynolds, Senior Fellow, Cato Institute DeSmogBlog contributor Farron Cousins writes, “Newsweek Gives Cato Institute Climate Denier A Platform.” That means my piece, “Hurricanes Harvey and Irma Can’t Be Blamed on Global Warming.” But how could I possibly be a “Climate Denier” when I openly accepted NASA’s estimate that “Globally-averaged temperatures in 2016 were 1.78…
