A substantial part of the Earths’ soil organic carbon (SOC) is stored in Arctic permafrost peatlands, which represent large potential sources for increased emissions of the greenhouse gases CH4 and CO2 in a warming climate. this is a Schematic overview of the main degradation pathways of plant polymers in the high-Arctic peatlands of Svalbard.

Ocean acidification Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.12,13 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year
Melting permafrost 'will DOUBLE carbon and nitrogen levels in the atmosphere': Experts issue chilling new climate change warning
Ocean acidification affects sea otters by making it harder for their prey to survive. Most sea otters prey on marine invertebrates - animals who use calcium carbonate as the main building block of their rigid exoskeletons. Even slight changes in ocean acidity can prevent some invertebrates from reaching adulthood.
