Donald Trump appointed climate change cynic Scott Pruitt as head of the US Environmental Protection Agency (EPA) last year.
The move was met with hostility by environmentalists, who said the appointment would have a negative effect on curbing carbon emissions.
Ken Cook, the head of the Environmental Working Group, told the New York Times:
[It is a] safe assumption that Pruitt could be the most hostile EPA administrator toward clean air and safe drinking water in history.
Those same critics may also have something to say about the Energy Department's international climate office banning the phrase "climate change".
Politico reports that, on the same day President Donald Trump signed an executive order reversing many of President Barack Obama's climate initiatives, officials at the State Department and Department of Energy (DOE) were told to avoid climate-related terms in memos and briefings.
The Trump administration seemingly wants to stick its fingers in its ears and ignore the issue of climate change.
Officials told Politico that they had not been given a banned words list, but had changed tone in memos and briefings to sit in line with the direction of the White House.
It's all a bit 'He Who Must Not Be Named'.
A DOE spokeswoman told Politico:
No words or phrases have been banned for this office or anyone in the department.
A source in another DOE office said that it was being judged more favourable to mention "jobs" and "infrastructure" rather than environmental topics.
A State Department official said:
People are taking their own initiatives to not use certain words based on hints from transition people.
Everyone is encouraged to finding different ways of talking about things.
In timely fashion, Al Gore released the trailer to his film 'An Inconvenient Sequel', which unsurprisingly puts Donald Trump in the crosshairs.
