So, get this, it turns out this whole "climate change" thing is a hoax. Not the scientific reality that earth is warming rapidly due to anthropogenic carbon dioxide, but the actual phrase. We hear Trump and other anti-science reactionaries repeat this same line, that "it used to be global warming, but now it's climate change, because derp derp winter is cold!" Tonight I learned that the term "climate change" was a purposeful propaganda exercise by the George W. Bush administration. In 2005, NAS started publishing documents that purposefully changed the term "global warming" to "climate change" at the recommendation of a consultant who wanted to make the issue less scary.
So, yeah, we should all stop saying climate change and go back to saying global warming.
In 2005, the National Academies of Sciences published a pamphlet that expressed the viewpoint that "climate change" was a more scientifically comprehensive description of what was happening to the planet. "The phrase 'climate change' is growing in preferred use to 'global warming' because it helps convey that there are changes in addition to rising temperatures," it said.
Shortly thereafter, in 2006, the Environmental Protection Agency changed the name of its Web site on the issue from "Global Warming" to "Climate Change." It plastered the National Academies quote on the superiority of "climate change" on the front page to explain the rationale.

"The contentious phrase global warming, first used by United Press International in 1969, seems to be undergoing a certain cooling; contrariwise, the more temperate phrase climate change is getting hot," the New York Times' William Safire wrote in his On Language column in 2005.
In the years prior, the Bush administration had expressed a clear preference for the term "climate change." In speeches on the issuestarting in 2002, Bush referred to "global climate change" and never mentioned "global warming." His administration formed "climate change" science and technology programs. There may well have been political motivation to change the name,
So, yeah, we should all stop saying climate change and go back to saying global warming.
