There will be a new push as to why these scientists have to be wrong -- From the article: What was driving this motion was not heat from the core, but cooling at Earth's surface.
They obviously didn't get the message that the Earth's surface never be referred to as "cooling".
I think you're being too logical.
It's perfectly within the bounds of possibility that these people will next be explaining to us that the surface of the earth can be cooling even though the atmosphere is warming.
