A study shows an increase of permafrost temperature at a global scale

Universidad De Barcelona

Permafrost, the ground below the freezing point of water 0 º for two or more years, is an element of the cryosphere which has not been as much studied as other soils like glaciers or marine ice, although it plays an important role in the climate evolution of the planet and in several human activities. Now, for the first time, a review of the state of permafrost on Earth has been carried out thanks to the data analysis of more than 120 drillings distributed around the Arctic and the Antarctica, as well as in mountains and high plains worldwide.
