Deep Frozen Arctic Microbes Are Waking Up

This has led to glacier melt and permafrost thaw levels that weren’t forecast to happen until 2050 or later. Other permafrost microbes (methanotrophs) consume methane. As melt-swollen Arctic rivers carried sediments from thawing permafrost to the sea, the genes for processing permafrost carbon were also transported. Permafrost thaw in Siberia led to a 2018 anthrax outbreak and the death of 200,000 reindeer and a child. With the coalescence of microbes reawakening from the deep and surface conditions unprecedented in human history, it is challenging to assess risks accurately without improved Arctic microbial datasets.
