Because "global warming."

Er… make that "climate change."

The new – more general – term for the allegedly human-caused alteration of the planet's weather. "Global warming" had to go because global cooling was also inconveniently happening.

This was becoming globally embarrassing.

"Climate change" is much better, because it always fits. The climate is constantly changing. And would do so (and has done so) regardless ofthe presence of man on this Earth. But why not just blame man for it?

For everything?

Perfect!

The fact that this re-branding was necessary says more about the politics of "climate change" than its scientific validity. Despite the near-unanimity of media Tele-Prompter readers and politicians, experts in the field (as opposed to "environmentalists," a non-degreed title anyone can claim) are far less certain about the assertion that recent changes are abnormal, much less the result of human activity – and so reluctant to endorse the imposition of extreme (and expensive) government regulations and taxes on billions of humans that will impoverish them but not the elites (including the Pope) whose super-sized carbon footprints will continue to tromp the Earth.
