Ted Cruz, a US presidential candidate, thinks it’s an attempt to hide the “warming pause”. But it was a Republican adviser who really pushed for the change.
The US Republican presidential candidate Ted Cruz had some things to say about global warming recently.
The senator for Texas complained that people had stopped talking about "global warming" and started saying "climate change".
He said: "You remember how it used to be called 'global warming' and then magically the theory changed to 'climate change'? The reason is it wasn't warming, but the computer models still say it is, except the satellites show it's not."

Cruz is relying on one dataset from one set of years – satellites over 17 years (18 or 16 would tell a different story) – while ignoring data from the oceans and the atmosphere. But that's a bigger question.
Luntz was an adviser to the George W Bush administration. In 2003 he wrote a memo, which was leaked to the Guardian, saying that "The scientific debate is closing [against the Republicans] but not yet closed. There is still a window of opportunity to challenge the science," and that:
Voters believe that there is no consensus about global warming within the scientific community. Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly. Therefore, you need to continue to make the lack of scientific certainty a primary issue in the debate.
