India, April 22 -- Experiments show warming temperatures increased metabolic activity among plants and microbial soil

The warming planet may alter the characteristics of tundra environments and could transform them from carbon sinks to carbon sources, a study has warned.

The study, Environmental drivers of increased ecosystem respiration in a warming tundra , revealed that the warming climate may assist ecosystem respiration, which will result in the release of carbon into the atmosphere. Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem.

Rising temperatures change the biogeochemistry of an area, affecting local soil by altering nitrogen levels and pH, the researchers found. ...
