Where, Exactly, Is The Man-made Climate Problem?

Guest Post by Willis Eschenbach Posted without comment, except a hat tip to Dave Burton and Willie Soon … There is no statistically significant difference between the two trends. Well, I guess that qualifies as a comment … Best to everyone on a day full of sunshine, w. My Usual Request: Quote the exact words…

Putting The Hype Back Into Hyperloop

Guest Post by Willis Eschenbach A recent article has discussed how Elon Musk’s “Boring Company” has raised $113 million dollars in startup capital. This is the company Musk formed to drill the tunnels for his proposed “Hyperloop” transportation system. It has encouraged me to discuss some of the engineering and practical problems with his LA-to-San…

Clouds Down Under

Guest Post by Willis Eschenbach [See Update at the end] Sometimes climate research is just plain funny. I wrote before about Irish rain and investigated whether there is any effect on the rain from the solar variations linked to sunspots. I was looking for evidence that the Svensmark hypothesis is true. Svensmark said that changes…

Tools to Spot the Spots

Guest Post by Willis Eschenbach People have asked about the tools that I use to look for any signature of sunspot-related solar variations in climate datasets. They’ve wondered whether these tools are up to the task. What I use are periodograms and Complete Ensemble Empirical Mode Decomposition (CEEMD). Periodograms show how much strength there is…

Why Ireland Is Green

Guest Post by Willis Eschenbach There’s an interesting study over at Climate of the Past entitled “A 305-year continuous monthly rainfall series for the island of Ireland (1711–2016)“ by Conor Murphy et al. Unfortunately, their link to their dataset was broken. So I got in touch with the Copy Editor, Anja Krzykowski, and she was…

Congenital Innumeracy

Guest Post by Willis Eschenbach I came across an article that hypes a new “carbon capture” plant with the following headline: The world’s first “negative emissions” plant has begun operation—turning carbon dioxide into stone   The article starts out as follows: There’s a colorless, odorless, and largely benign gas that humanity just can’t get enough of.…

How Not To Model The Historical Temperature

Guest Post by Willis Eschenbach Much has been made of the argument that natural forcings alone are not sufficient to explain the 20th Century temperature variations. Here’s the IPCC on the subject: I’m sure you can see the problems with this. The computer model has been optimized to hindcast the past temperature changes using both…

Where The Warmth Is

Guest Post by Willis Eschenbach I got to thinking about the “hiatus” in warming in the 21st Century, and I realized that the CERES satellite dataset covers the period since the year 2000. So I’ve graphed up a few views of the temperature changes over the period of the CERES record, which at present is…
