Microorganisms' climate adaptation can slow down global warming

A new study from Lund university in Sweden shows the ability of microorganisms to adapt to climate warming will slow down global warming by storing carbon in soil.

In the study, researchers collected soil samples from across Europe in a wide range of temperatures, from minus 3.1 to 18.3 degrees Celsius. The samples revealed that microorganisms in soils -- such as bacteria and fungi -- are strongly adapted to their local climate when it comes to growth and respiration. However, the researchers surprisingly demonstrated that microorganisms can adapt to temperature changes. The organisms can even benefit from these changes.

A biology researcher at Lund University, Carla Cruz Paredes, said that despite decades of scientific pondering, researchers have not been able to determine whether microorganisms can adapt to warming, and if they do. We can now confirm that this is the case, and that the organisms can actually mitigate climate warming.

The new study, published in the scientific journal Applied and Environmental Microbiology, also reveals that groups of microorganisms react differently to warming. Bacteria and fungi differ in their sensitivity to temperature changes, with bacteria being more sensitive than fungi. Moreover, microbial growth is more sensitive to temperature changes than respiration. These differences in temperature sensitivity have important implications for predictions of future carbon losses and storage, as well as how the soil is affected by climate warming.
