Between 30 metres and 90 metres below the surface of the Caribbean Sea, an ancient sponge species that grows a hard skeleton has been quietly recording changes in the ocean temperature for hundreds of years.

Now those sponges are at the centre of a bold and controversial claim made in a leading scientific journal that, since the start of the Industrial Revolution, the planet may have already warmed by 1.7C – half a degree more than estimates used by the United Nation’s climate panel.

Several leading scientists urged caution, saying the research had “over-reached” and questioned whether such a bold claim could be made based on one sponge species from a single location.

But Prof Malcolm McCulloch of the University of Western Australia, who led the research published in the journal Nature Climate Change, said the results were robust.

No is arguing otherwise.

One paper does not make a "fact". Years of established research and widespread consensus barely justifies labeling a subject as a "fact".

Have you already forgotten the room temperature superconductor claims from last year?

Let me be absolutely clear. I am in no way trying to discredit this paper. I see no reason to question their findings, it's good science and absolutely should be followed up on. However, I take strong exception to people jumping on any half decent study and treating it as gospel.
