On average, it would then amount to up to three meters per year - in the entire Arctic. Global warming is causing permafrost in the Arctic to thaw and sea ice to melt. As a result, coasts are less protected and are being eroded, while carbon stored in the soil and carbon dioxide are being released into the ocean and atmosphere. In a first, researchers at Universität Hamburg have now calculated the future scale of these processes for the entire Arctic. Their conclusion: each degree of warming accelerates them considerably. Their findings have now been published Climate Change.
