Climate F-Words

by Roy W. Spencer, Ph. D.

[Ed.  Dr. Roy Spencer wrote a post (22 March 2018) disagreeing with Lord Monckton’s theory that climate scientists have over-estimated feedback by a factor of 2, because they have been using the feedback  equations incorrectly.  Dr. Spencer agrees with the factor of 2 error, but he disagrees with the reason given by Lord Monckton.  In response, Lord Monckton has countered Dr. Spencer’s argument with a post of his own on Spencer’s blog.  The original Spencer post can be found here with Lord Monckton’s counter argument  here.]

recent article by Lord Christopher Monckton over at WUWT argues that there has been an “elementary error of physics” that has led to climate sensitivity being overestimated by about a factor of 2.

I agree with the conclusion but not the reason why. It is already known from the work of Otto et ahttp://www.drroyspencer.com/wp-content/uploads/Trump-forcing-and-feedback-550x309.jpgl. (2013), Lewis & Curry (2015) and others that the climate system (including the deep oceans) has warmed by an amount that suggests a climate sensitivity only about half of what the models produce (AR5 models warm by an average of 3.4 deg. C in response to a doubling of CO2).

But the potential reasons why are many, and as far as I can tell not dependent upon Christopher’s arguments. For those who don’t know, Lord Monckton is a pretty talented mathematician. However, like others I have encountered over the years, I believe he errs in his assumptions about how the climate research community uses — and does or does not depend upon — the concept of feedback in climate modeling.

The Future of Everything

No one can really predict the future, but I would like to speculate on it a bit and maybe unravel a few promising threads from the tapestry of time and

see what one or two future worlds might look like.

 

 

Demographic threads, a discussion of future growth, will Capitalism survive?, Artificial Intelligence (AI) in the future, the future of work, emerging medical processes, the future of poverty and the influence of global trade are a few of the hot spots of future development. And what might the future climate turn out to be?

Demographics and the Future

In the past we have briefly discussed global demographic trends and I will only focus on them as they might influence the future of growth, poverty, work and automation issues. Continue reading “The Future of Everything”

Eleven-Year Major Hurricane Drought: Much More Unusual than Two Cat 4 Strikes

Roy Spencer

[This is a reprint (21 Sep 2017) from Dr. Roy Spencer’s blog (drroyspencer.com) in which he makes the point that two category 4 hurricanes making landfall in the same year is far more likely than the recent  eleven year period with no major hurricane landfalls that preceeded the two category 4 hurricanes.  Assuming the 177 year return period for no major hurricanes in 9 years estimated by NASA was correct, we agree with Dr. Spencer that the return period for no major hurricanes in 11 years would be 560 years.  Ed.]

Weather.com published an article noting that the two Cat 4 hurricane strikes this year (Harvey and Irma) is a new record. Here’s a nice graphic they used showing both storms at landfall.

The AMS Scolds Rick Perry for Believing the Oceans are Stronger than Your SUV

Dr. Roy Spencer responds to an American Meteorological Society attack on DOE Secretary Rick Perry’s comments during an interview on CNBC’s “Squack Box” regarding climate change.

DOE Secretary Rick Perry

[This post originally appeared on Dr. Roy Spencer’s blog on 22 June 2017.  Like many others, Dr. Spencer resigned in disgust from the American Meteorological Society some time ago because of their exaggerated statements regarding climate change.  Now in an obvious display of unscientific hyperpbole, the  AMS has attacked DOE Secretary Rick Perry.  Dr. Spencer takes them to task for the wildly overstated claims regarding climate change that they made in their attack on the Secretary. 

Dr. Spencer says,

“I am ashamed that the climate research community allows such pronouncements to be made. The AMS became a global warming advocacy group many years ago, and as a result it lost a lot of established members, including myself.”  ]

Breaking: Fatal Courtroom Act Ruins Michael ‘hockey stick’ Mann

[This article by John O’Sullivan regarding Michael ‘Hockey Stick’ Mann’s libel lawsuit against Dr. Tim Ball originally appeared at Principia-Scientific followed by Technocracy.News and is reproduced for your information and entertainment.  Who can forget “Mike’s nature trick” to hide the decline.  For those of us who are skeptical about catastrophic, anthropogenic, climate change, this is really big, and it was a wonderful 4th of July gift.]

Penn State climate scientist, Michael ‘hockey stick’ Mann commits contempt of court in the ‘climate science trial of the century.’ Prominent alarmist shockingly defies judge and refuses to surrender data for open court examination. Only possible outcome: Mann’s humiliation, defeat and likely criminal investigation in the U.S. Continue reading “Breaking: Fatal Courtroom Act Ruins Michael ‘hockey stick’ Mann”
