"The latest Nature-published research gives a snapshot from ancient Antarctica ‘blue’ ice drilled in the Allan Hills area. It looks back further in time past the usual 800,000 ice core records. The key finding is that over the last three million years, when sea levels fell and ice periods intensified, the level of the main ‘greenhouse’ gases remained remarkably stable. For the first time, the work has pushed the direct gas measurements back into the late Pliocene era. Over the last three million years moving into the Pleistocene, global temperatures showed a long-term cooling trend of several degrees Celsius, interrupted by increasingly large interglacial oscillations. Interglacial temperature swings, as in the current Holocene, often see temperatures rise by 5°C and more."
