The US Geological Survey estimates theres a total of 1,656,000 tonnes of mercury trapped in polar ice and permafrost: roughly twice the global amount in all other soils, oceans, and atmosphere. These ice ages are associated with a large drop in global temperatures - 4C or more below today's levels - with much larger changes over land and in the high latitudes. Professor Wadhams stresses that there are uncertainties - cloud cover over the Arctic could change and help reflect back some of the sun's radiation. of sugar over the ice cubes in another bowl, and tsp. Christiansen, who is also president of the International Permafrost Association, tells me, temperatures are increasing inside the permafrost at relatively high speed then, of course, what was permanently frozen before can become released. In 2016, the autumn temperatures in Svalbard remained above zero throughout November, the first time this has happened in the records that we have, going back to 1898, says Christiansen. Most studies on Arctic methane sources focus on permafrost, because these frozen soils tend to hold large reserves of organic carbon that could be converted to methane when they thaw due to climate warming.
