The proper way of looking for causal relationships between time series data (e.g. between atmospheric CO2 and temperature) is discussed. While statistical analysis alone is unlikely to provide “proof” of causation, use of the ‘master equation’ is shown to avoid common pitfalls.  Correlation analysis of natural and anthropogenic forcings with year-on-year changes in Mauna Loa CO2 suggest a role for increasing global temperature at least partially explaining observed changes in CO2, but purely statistical analysis cannot tie down the magnitude. One statistically-based model using anthropogenic and natural forcings suggests ~15% of the rise in CO2 being due to natural factors with an excellent match between model and observations for COVID-19 related downturn in global economic activity in 2020.

The record of atmospheric CO2 concentration at Mauna Loa, Hawaii since 1959 is the longest continuous record we have of actual (not inferred) Continue reading “Explaining Mauna Loa CO2 Increases with Anthropogenic and Natural Influences”

CRITIQUE of the June 2021 AARP Bulletin: “Climate Change and You”

Robert W. Endlich

A few months ago, I picked up the June 2021 issue of the AARP BULLETIN. What greeted me was inch-high letters blaring the title of their feature article: “CLIMATE CHANGE AND YOU; Extreme Weather Is Affecting Older Americans’ Daily Life…”

On the front cover, four huge images, vivid color photos: white-shirted man on rooftop looking into a wildfire in southern California, flood victims of Hurricane Florence in an overloaded boat in South Carolina, woman in jeans and white shirt in Mississippi assessing damage after Hurricane Katrina, and a view of slushy streets in Texas, February 2021.

 

Figure 1. Screenshot of the AARP BULLETIN’s front cover graphics for the feature article, ”What You Need to Know About Climate Change.” The authors don’t know it but, what they are really describing is wild weather, part of the climate we have. AARP’s ignorance starts right here, with this cover graphic.

The photos are dramatic, of course, classic emotional appeals by the media. But I thought,

“Is AARP subliminally trying to tell us that wildfires are new Continue reading “CRITIQUE of the June 2021 AARP Bulletin: “Climate Change and You””

Materials Acquisition for Global Industrial Change

 Via executive orders, regulatory edicts and partisan Green New Deal legislation, President Biden intends to slash US carbon dioxide and other greenhouse gas emissions by 50 percent below their 2005 peak by 2030, and eliminate them (and fossil fuel use) by 2050. But, as AOC’s former chief of staff noted, the GND is not just about transforming America’s energy

system; it’s about changing the entire economy.

This radical transformation is driven by three fundamental articles of faith, none of them based on reality.

The crisis of manmade climate cataclysms necessitates this GND. Natural forces no longer play a role. Rising temperatures since the Little Ice Age Continue reading “Materials Acquisition for Global Industrial Change”

An analysis of the 17 April 2018 NMSU Climate “Education” presentation by Dr David Dubois

Robert W. Endlich

… a patchwork of stories where propaganda and misinformation are presented as fact.

IS EMOTION THE BASIS OF EDUCATION?

For the lead presentation of a series which was purported to bring “Climate Education” to interested members of the Las Cruces, NM and New Mexico State University communities, Dave DuBois starts off with an emotional appeal to the audience, not a fact-based introduction. The link to his presentation is at https://sustainability.nmsu.edu/nmsuccess/ scroll to the bottom.

His subsequent sequence is filled with a patchwork of stories where propaganda and misinformation are presented as fact. Sometimes Dr. DuBois mentions tools of the trade in understanding climate history, including ice core proxies, sedimentation records, and natural climate cycles, including El Nino-Southern Oscillation and the Pacific Continue reading “An analysis of the 17 April 2018 NMSU Climate “Education” presentation by Dr David Dubois”

The front-page article, by Leah Romero from New Mexico in Depth, was accompanied with a foreboding graph and story, showing seemingly unending upward temperatures, copy below, with an aura of authority. After all, the data came from New Mexico’s Land Grant College, Continue reading “Another False Climate Alarm”
