A study by the University of Stockholm, with scientists from other countries and the Catalan Institute of Climate Sciences (IC3), reports that rising in the temperatures are causing the thawing of the permafrost (semi-permanently frozen ground), and activating the organic deposits of carbon, thoses deposits can arrive to 44 million tonnes a year, what means, ten times more than what was estimated before.
The study also says that around two-thirds of the carbon in the permafrost, can scape to the atmosphere as CO2, causing greenhouse effect, said Laura Sanchez-Garcia, the researcher of IC3.
Warming higher than the average; half of the carbon deposits are in the Arctic coast and them are suffering a warming two times higher than the average, damage is not very evident but is growing.
This study start in 2008 and made possible to check the conceptions about the conservation of carbon in the artic and the role of its flow in the weather.
