PART 1. Inside the machinery of doubt - money, think tanks, politicians and “experts” all agree in Texas
Will Happer rebranded part of the George C. Marshall Institute (GMI) as the CO2 Coalition (“CO2Co”) in 2015, but was little noticed, as GMI finally ended  “not with a bang but a whimper.”  Gayathri Vaidyanathan reported in EENews: 

Three deadly sins in academe and journalism are Falsification, Fabrication and Plagiarism (FFP).¹  Political speechwriters normally take great pains to avoid obvious text-copy plagiarism,² but on Monday Melania Trump's speech plagiarized text from Michelle Obama. Trump employee Meredith McIver took responsibility, but new analysis here raises more doubts.

Climate denial is pervaded by FFP examples, the most famous likely that around the Wegman Report, where plagiarism and reactions to its exposure resemble those in the Trump case.

First, high-profile work is trusted to inexperienced people, who can make silly errors. Competent organizations check.
Then, exposure generates contradictory excuses, some clear fabrications, such as personal attacks on irrelevant people.
Finally, the organization takes surprisingly long to produce official explanations, about which doubts may be raised.

Senators Launch Resolution, Speech Blitz Calling Out #WebOfDenial Blocking Climate Action summarized the comments by 19 US Senators July 11-12.  The text of their remarks was extracted from the Congressional Records, annotated and combined into the attached 42-page PDF.  That is easily searchable, and may help guide selection of videos to watch.

They offered strong words, including Senator Elizabeth Warren's analysis of Viscount Christopher Monckton.

Pink shading is used to emphasis denierfunders, groups and indviduals, many found in the DeSmog Research Database or other analyses at DeSmog, which was mentioned 8 times by the Senators.

The two tables below give page numbers of Senators' remarks, showing first the funders they mentioned, and then the denial groups.  Many Senators mentioned the Kochs, ExxonMobil, tobacco, and Donors Trust.

Overview
On 04/13/15, Peabody Energy followed other major coal companies into bankruptcy, and days later lost a battle in a landmark legal war on Minnesota's Social Cost of Carbon (SCC).  The “best” gang¹ of climate denial outliers they could hire tried to confuse the court with absurd claims in both science and economics. The Judge was not fooled, and ruled unambiguously, as reported by Bloomberg BNA, University of Minnesota Consortium on Law and Values and MPRNEWS:
Updated climate change costs make coal-fired power less attractive:

Paid by Alpha Natural Resources, Arch Coal, Peabody Energy and others undisclosed, David Schnare and Chris Horner of Energy and Environment Legal Institute* generate endless time-wasting Freedom of Information Act (FOIA) requests to harass climate scientists, as recently summarized by the Climate Science Legal Defense Fund.  

Reasonable FOIAs are valuable, but the rules can be abused with relatively low effort to impose large costs for “fishing expeditions.” It seems many state governments have not yet clarified rules well enough to avoid waste of taxpayers' money.

EELI’s open records litigation against the University of Arizona, for the emails of Malcolm Hughes and Jon Overpack, grinds on with another recent development, Schnare is not a member of the Arizona Bar, so involved Jonathan Riches of the Goldwater Institute. In their earlier Reply Brief, p.11, they wrote misleading claims against (deceased) Stephen Schneider, to attack Hughes and Overpeck, starting:

The George C. Marshall Institute (GMI) was a leader in climate denial from 1990 onward, but disbanded in 2015. Its chairman Will Happer and CEO WIlliam O'Keefe rebranded its climate denial effort as the CO2 Coalition, more accurately a CoalOILition.

Of its 18 people, 15 signed Happer's “300 scientists” (sic) letter to help Lamar Smith(R-TX) waste more taxpayer money harassing NOAA. Early analysis of the signers list makes it look even sillier than Happer's 2009 petition to the American Physical Society, as will be seen in a forthcoming detailed post. Oil and coal industry people are well-represented.

Inspired by DeSmog UK's recent exposure of Patrick Moore's work for European coal, this post summarizes known connections of those involved in the CO2 CoalOILition. People were tagged Coal and/or OIL, explained below.¹  For example, of 18, five worked directly for Exxon, Shell or the American Petroleum Institute.  Also, 14 have been involved with Heartland ICCC meetings.
