Back in 2013 it was thought that the coldest surface temperature on Earth, recorded in Antarctica, was -135°F (-93°C). However this year the study has been revised and scientists announced that on the coldest site on Earth, temperatures can drop even lower, to -144 °F (-98 °C). They were observed during polar night, in wintertime. This record of -144 °F (-98 °C ) is about as cold as it is possible to get at Earth’s surface, according to the scientists. The conditions under which such low temperature can occur, are dry air and a clear sky, persisting for several days. If they persisted longer, the temperature could drop even lower, but researchers don’t think that it is likely to happen.
