As we work to curb emissions, another source of greenhouse gases is coming to the surface. An international study released this fall shows that permafrost thaw could contribute as much greenhouse gases to our atmosphere as a large industrial nation by the end of the century. In the Arctic, warming is amplified, with annual temperatures having warmed 2.3 C since 1948, more than twice the global rate, according to Environment and Climate Change Canada.
