I think there are probably quite a lot of ramifications to this news for climateers to consider which I’m too tired to think of. Over to the talkshop massive:
The core of the Earth is nearly 1,000 degrees hotter than previously thought, making it as fiery as the surface of the sun.
Following new experiments, scientists have established that the core temperature is 6,000 C, much higher than the previous estimate of 5,000.
Using X-rays to probe into the behaviour of iron crystals, putting samples of iron under extreme pressure, researchers were able to examine how iron crystals melt and form.
The new tests, using one of the world’s most intense sources of X-rays located at the European Synchrotron Radiation Facility, the research team were able to re-create the same pressure at the core.
