Bacteria, Viruses and Carbon: how microorganisms in arctic soils can alter our climate

Wetland soils store 20-30% of global soil carbon, that carbon is mostly controlled by bacterial populations. Arctic wetland soils store twice as much carbon as the atmosphere, but are frozen year round as permafrost which limits microbial activity. We try to predict what will happen with microbial communities and soils when temperatures continue to warm, but we’re finding out it’s more than just bacteria that are driving arctic carbon cycles.
