You hear it almost unfailingly whenever we get hit with a cold snap, such as what has gripped North Texas — and much of the rest of the country of late.

It comes from climate change deniers who scoff at the notion that our climate is changing, and the globe is getting warmer. I heard it the other morning while having breakfast with some gentlemen with whom I am acquainted. They dissed the notion of global warming.

I didn’t say a word, as I don’t know them well enough to challenge such nonsense.

One of our local TV meteorologists put it well recently in a public service announcement. The weather, he said, defines what is happening in the moment, while “climate” defines longer-term trends.

That was his way of telling us to disregard current weather conditions when discussing whether the climate is changing.

I believe he is correct.

I remember the time during an earlier D.C. cold snap when climate change denier U.S. Sen. Jim Inhofe of Oklahoma took a snowball to the floor of the Senate to make some kind of idiotic argument that climate change is a hoax, a product of liberals seeking to damage to the fossil fuel industry which, I should add, was a big contributor to Inhofe during his years in public life.

The term “global warming” has for all intent been replaced by “climate change,” which I believe is a more inclusive description of what is happening to our good Earth. We indeed are suffering through more climate extremes from year to year.

The data we receive from worldwide meteorological organizations is beyond dispute. It is that despite these cold snaps, Earth’s mean temperature is rising year over year, the global ice caps are melting, mountain glaciers are receding and that thousands of species of wildlife are endangered by the changing climate.

When I hear the climate change deniers dismiss the evidence because they’re bundling up to protect against frigid air temps, I am left only to shake my head in dismay at their ignorance.
