Water vapor and Covid-19: The viral threat of cold, dry weather

Even before Covid-19, most people were acutely aware of the viral threat of winter. Seasonal colds seem to be more abundant during the winter while the widely broadcasted threat of flu season and subsequent chore of annual flu vaccinations are predictable components of late fall. However, I have also had my fair share of exceptional warm weather colds. I have encountered a collection of rumors as to why viral infections such as the common cold and influenza are statistically worse during the winter, but I have never really done enough research to actually believe any of them, or care, for that matter. Insert Covid-19.

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.
