[def. dictionary.com] a long-term change in the earth’s climate, especially a change due to an increase in the average atmospheric temperature: Melting glaciers imply that life in the Arctic is affected by climate change. … Foremost among them is the role of birth control in dealing with climate change.
[added comments] The above appears to be an overly simple definition of climate change and the last sentence is open to extensive discussion. There is much more to climate change than temperature. There is wind, precipitation, humidity, atmospheric pressure, and other elements. Also, there is nothing unusual about climate change, because the climate is constantly changing. Climate is simply average weather. What that is depends on the averaging period. Some say that at least 30 years of measurements are required to compute climatic averages, but that is not necessarily correct. There are good reasons to consider 60 years of measurements due to the 60-year Pacific Decadal Oscillation (PDO). The limiting factor in computing climatological averages is the amount of measurement data available. Generally, there is no more than 100 to 150 years of data unless proxy data are used. Regardless, the climatological average will be different for each different averaging period. Consequently, we must conclude that we really do not have sufficient data to know what the climatological averages are not to mention how they are changing.
Climate Crisis Inc. gets billions to promote imaginary man-made cataclysm – but attacks realists
By Paul Driessen
The climate crisis industry incessantly claims that fossil fuel emissions are causing unprecedented temperature, climate and weather changes that pose existential threats to human civilization and our planet. The only solution, Climate Crisis, Inc. insists, is to eliminate the oil, coal and natural gas that provide 80% of the energy that makes US and global economies, health and living standards possible.
Failing that, CCI demands steadily increasing taxes on carbon-based fuels and carbon dioxide emissions.
However, as France’s Yellow Vest protests and the latest climate confab in Poland demonstrated, the world is not prepared to go down that dark path. Countries worldwide are expanding their reliable fossil fuel use, and families do not want to reduce their living standards or their aspirations for better lives.
Several years ago, I purchased a Kindle copy of John Kehr’s book, “An Inconvenient Skeptic,” breezed through it, copied several graphics, and thought, “this is pretty good; it might make the beginnings of a presentation someday.”
Couple of weeks ago Bernie McCune emailed; had previously penciled in doing the January 2019 meeting presentation, found he’d be unable. With no others having a topic ready to go, “someday” arrived the day I got that email from Bernie.
I busied myself capturing images from the book, showing seasons, geography, and useful information on temperature, measurements, and historic temperatures.
In describing the errors in the Fourth National Climate Assessment, ‘NCA4’, I’ll use the words from the Executive Summary which purport to link climate changes in the USA to global climate change.
The first claim, “The last few years have also seen record-breaking, climate-related weather extremes,“ is shown to be false, simply by examining climate records, some from the National Climate Data Center.
Richard Siegmund Lindzen is an American atmospheric physicist known for his work in the dynamics of the atmosphere, atmospheric tides, and ozone photochemistry. He has published more than 200 scientific papers and books. From 1983 until his retirement in 2013, he was Alfred P. Sloan
Professor of Meteorology at the Massachusetts Institute of Technology. He was a lead author of Chapter 7, “Physical Climate Processes and Feedbacks,” of the Intergovernmental Panel on Climate Change’s Third Assessment Report on climate change. He has criticized the scientific consensus about climate change and what he has called “climate alarmism.”

This post is in four sections: before Convening Lead Author Dr Gregg Garfin arrived at NMSU, the lecture itself, the question I asked during the “Q and A” session and concluding thoughts. There is also an addendum.
