(ORDO NEWS) — Scientists have made serious mistakes in the past in their research on the Ice Age. They were wrong about the temperature readings. It was believed that during the last ice age, the temperature in Antarctica averaged around -9 degrees . However, the assumptions were not correct. They have been refuted by new research.
It is reported by Phys.org.
Cristo Bizerta, the head of an international team of scientists from the University of Oregon, discovered these deviations. It turned out that it was 10 degrees colder in Antarctica than in our time, but not everywhere. In the central part, the temperature difference between 20 thousand years ago and today is not so significant. In the distant past, it was coldest here by only 4-5 degrees.
Two methods were used for the study. Scientists have studied ice cores from 7 different parts of Antarctica. They also used the borehole thermometry method, which made it possible to find out the ice temperature at different depths. Scientists have also studied the snow cover, which accumulates and turns into ice. Further, using this data, it was possible to model and reconstruct the climate that was 20,000 years ago.
By knowing the exact temperatures during and after the ice age, scientists will be able to more accurately model the predicted scenarios in the event of abrupt climatic changes on our planet. Paleoclimatologist Ed Brook spoke about this.
