Can science and the truth withstand the merchants of poison?

"Here is the truth: The Earth is round; Saddam Hussein did not attack us on 9/11; Elvis is dead; Obama was born in the United States; and the climate crisis is real. It is time to act."

Climate of Denial

Al Gore
Rolling Stone

The first time I remember hearing the question "is it real?" was when I went as a young boy to see a traveling show put on by "professional wrestlers" one summer evening in the gym of the Forks River Elementary School in Elmwood, Tennessee.

The evidence that it was real was palpable: "They're really hurting each other! That's real blood! Look a'there! They can't fake that!" On the other hand, there was clearly a script (or in today's language, a "narrative"), with good guys to cheer and bad guys to boo.

But the most unusual and in some ways most interesting character in these dramas was the referee: Whenever the bad guy committed a gross and obvious violation of the "rules" — such as they were — like using a metal folding chair to smack the good guy in the head, the referee always seemed to be preoccupied with one of the cornermen, or looking the other way. Yet whenever the good guy — after absorbing more abuse and unfairness than any reasonable person could tolerate — committed the slightest infraction, the referee was all over him. The answer to the question "Is it real?" seemed connected to the question of whether the referee was somehow confused about his role: Was he too an entertainer?

That is pretty much the role now being played by most of the news media in refereeing the current wrestling match over whether global warming is "real," and whether it has any connection to the constant dumping of 90 million tons of heat-trapping emissions into the Earth's thin shell of atmosphere every 24 hours.

Climate Change and the Integrity of Science

We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts. There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything. When someone says that society should wait until scientists are absolutely certain before taking any action, it is the same as saying society should never take action. For a problem as potentially catastrophic as climate change, taking no action poses a dangerous risk for our planet.

Scientific conclusions derive from an understanding of basic laws supported by laboratory experiments, observations of nature, and mathematical and computer modeling. Like all human beings, scientists make mistakes, but the scientific process is designed to find and correct them. This process is inherently adversarial—scientists build reputations and gain recognition not only for supporting conventional wisdom, but even more so for demonstrating that the scientific consensus is wrong and that there is a better explanation. That's what Galileo, Pasteur, Darwin, and Einstein did. But when some conclusions have been thoroughly and deeply tested, questioned, and examined, they gain the status of "well-established theories" and are often spoken of as "facts."

For instance, there is compelling scientific evidence that our planet is about 4.5 billion years old (the theory of the origin of Earth), that our universe was born from a single event about 14 billion years ago (the Big Bang theory), and that today's organisms evolved from ones living in the past (the theory of evolution). Even as these are overwhelmingly accepted by the scientific community, fame still awaits anyone who could show these theories to be wrong. Climate change now falls into this category: There is compelling, comprehensive, and consistent objective evidence that humans are changing the climate in ways that threaten our societies and the ecosystems on which we depend.
