I recently engaged in a brief Facebook “scuffle” with a couple of former journalism colleagues about climate change. They argue that the planet isn’t warming after all, citing studies published in the United Kingdom that back up their contention.

I’ve argued for some time that climate change is real. The only debate, as I’ve viewed it, is whether it’s caused by human beings or whether it’s part of Earth’s ecological cycle.

Well … yet another new report concludes the climate is changing and that — you guessed it — humankind is the culprit. CNN.com reports that the researchers among the most learned in the world and their findings are considered to be a bellwether.

Oh, my. Here we go again.

CNN.com reported today: “Climate scientists are 95 percent confident — that is to say, surer than ever — that humans are responsible for at least ‘half of the observed increase in global average surface temperatures since the 1950s.'”

The study comes from the U.N. International Panel on Climate Change. I know exactly what my friends on the right — the climate-change deniers — are going to say about that: The United Nations? Everyone knows the U.N. is run by a bunch of political lefties who are out to destroy the industrial world as we’ve known it. They point to the occasional cold snap that blows in over the Panhandle as “proof” that global warming and climate change are hoaxes cooked up by former Vice President Al Gore’s cabal of environmental whack jobs.

I tend to view the U.N. — and Vice President Gore — more seriously than their critics.

CNN reported further: “Scientists are 90 percent sure that 1981-2010 was the warmest such span in the last eight centuries, and there’s a 66 percent chance that it was the warmest 30-year period in the last 1,400 years.

“While the last 15 years have not warmed as quickly, we’ve seen steady warming over most of the globe, and we haven’t seen a below-average temperature month since February 1985.”

Is this the end of the debate? Hardly. It’s just going to heat up even more … kind of like the way the planet has been getting hotter.
