When someone is delusional about climate change, it makes them feel better when they join with another 57 people who are equally delusional. That is called groupthink.

Climate groupthink believes human emissions cause climate change. They have no evidence to support their belief. So, to defend themselves they attack and block those who disagree with their belief. You will notice they do not list any evidence to support their belief.

On March 5, 2019, 58 “former national security leaders” signed a letter addressed to President Trump. They claim,

“climate change is real, it is happening now, it is driven by humans, and it is accelerating. The overwhelming majority of scientists agree: less than 0.2% of peer-reviewed climate science papers dispute these facts.”

They sound like used-car salesmen who desperately need to sell you worn-out car. The “overwhelming majority of scientists” do not agree that humans cause climate change:  

  1. The promoters of human-caused climate change do not use the scientific method. So, they are not scientists.
  2. I can count about 2000 atmospheric physicists who say we are not causing climate change. There are likely not over 4000 atmospheric physicists on the planet.
  3. The alarmist side counts ecologists, pediatricians, college sophomores, and “environmentalists” as “experts” in climate cause and effect.
  4. The number of papers has no relevance. There is no climate physics paper that shows humans cause climate change that has not violated physics.

They say they signed their letter because they

“are deeply concerned by reports that National Security Council officials are considering forming a committee to dispute and undermine military and intelligence judgments on the threat posed by climate change.”

They are concerned all right. They do not want a Presidential science panel to peer-review the scientific basis of their climate claims.

They say the people who disagree with them are,

“second-guessing the scientific sources used to assess the threat, such as the rigorously peer-reviewed National Climate Assessment, and applying that to national security policy.”

The National Climate Assessment (NCA) presents no evidence to support its claim that human CO2 causes climate change.

Read the NCA (if you want to waste your time). You will find long discussions about how climate changes and the damage climate change causes. You will find loads of cited papers. But you will find no evidence that human CO2 causes climate change.

The NCA merely ASSUMES we cause the rise in atmospheric CO2. The fact that atmospheric CO2 has increased does not prove we caused the increase. And if we did not cause the increase then we do not cause climate change. Checkmate.

My preprint and other published papers prove this NCA assumption is wrong. The last thing Americans want is their national security policy based on the National Climate Assessment.

They are the ones who morph climate science into politics.

“Imposing a political test on reports issued by the science agencies, and forcing a blind spot onto the national security assessments that depend on them, will erode our national security.”

They say,

“It is dangerous to have national security analysis conform to politics. Our officials’ job is to ensure that we are prepared for current threats and future contingencies. We cannot do that if the scientific studies that inform our threat assessments are undermined.”


Science is based upon proving theories are wrong. They oppose climate truth because it undermines their political positions. They are afraid of a peer review. Why?

“Our national security community will not remain the best in the world if it cannot make decisions based on the best available evidence.”

“Best available evidence”? 

They don’t understand scientific evidence. Their theoretical base is in the reports by the United Nations Intergovernmental Panel on Climate Change. Their theory makes wrong predictions. Therefore, their climate theory is wrong.

Statistics prove they are wrong:

The statistical correlation between annual human CO2 emissions and annual changes in CO2 in the atmosphere is ZERO! (See Munshi reference here.) Where there is no correlation, there is no cause and effect. There is NO rational scientific basis to claim or believe that human CO2 emissions CAUSE the climate to change.

They are guilty of malpractice.

The signers are not climate physicists. They don’t know how to determine cause and effect for climate change. It would not matter if 10,058 government-paid dignitaries and high-ranking officials signed their letter. They would still be wrong.

The signers of the letter threaten America.

By assuming human CO2 causes dangerous climate change, they threaten our economy and our national security. Their signed letter is bad for science, bad for national security, and bad for America.
