Climate-change ‘deniers’ are accused of heresy by true believers. That doesn’t sound like science to me.
Are there any phrases in today’s political lexicon more obnoxious than “the science is settled” and “climate-change deniers”?
The first is an oxymoron. By definition, science is never settled. It is always subject to change in the light of new evidence. The second phrase is nothing but an ad hominem attack, meant to evoke “Holocaust deniers,” those people who maintain that the Nazi Holocaust is a fiction, ignoring the overwhelming, incontestable evidence that it is a historical fact. Hillary Clinton’s speech about climate change on Monday in Des Moines, Iowa, included an attack on “deniers.”
The phrases are in no way applicable to the science of Earth’s climate. The climate is an enormously complex system, with a very large number of inputs and outputs, many of which we don’t fully understand—and some we may well not even know about yet. To note this, and to observe that there is much contradictory evidence for assertions of a coming global-warming catastrophe, isn’t to “deny” anything; it is to state a fact. In other words, the science is unsettled—to say that we have it all wrapped up is itself a form of denial. The essence of scientific inquiry is the assumption that there is always more to learn.
