For more about a little bit of research on soil microbes and CO2 levels.

I love the tagline of this site: Accelerating publication of peer-reviewed science.
And while there is zero alarmism, threats of glaciers or floods, dire predictions about famines or economic disaster, the conclusion appropriately states, “Together, these results highlight the urgent need for considering the interactive impact of C and N availability on microbial activities and decomposition when projecting soil C balance in N-rich systems under future CO2 scenarios.”
