It is ironic that, on the 53rd anniversary of the first moon landing, President Biden would tell the nation that man-made climate change “is literally — not figuratively — a clear and present danger” (“Biden unveils executive action on climate change but stops far short of declaring national emergency,” Web, July 20). Included in the long list of well-qualified people skeptical of what Mr. Biden calls an “emergency” are Apollo 11 astronaut Buzz Aldrin and at least five other Apollo astronauts.

In fact, 10 years ago, 49 former NASA scientists and astronauts sent a letter to then NASA Administrator Charles Bolden, criticizing the agency for advocating a high degree of certainty that man-made carbon dioxide was a major cause of climate change — while ignoring empirical evidence that calls the theory into question.

Signing the open letter were Walter Cunningham (Apollo 7), Charles Duke (Apollo 16), Richard Gordon (Apollo 12), Harrison “Jack” Schmitt (the only scientist to yet walk on the moon during Apollo 17) and Al Worden (Apollo 15). Others included Apollo flight directors and former directors of Johnson Space Center Christopher Craft and Gerald C. Griffin.



Apollo astronauts came back to the Earth strongly committed to real environmental protection. It’s high time Mr. Biden did the same instead of fixating on the nonsensical climate scare.
