In the concrete jungle at the core of a city, carbon dioxide (CO2) emissions are dominated by the fossil fuels burned by the dense concentrations of cars and buildings. Boston University researchers now have shown, however, ...

Carbon sequestration in soil: The potential underfoot

Declining greenhouse gas emissions from European cropland could compensate for up to 7 percent of annual agricultural emissions from the region, according to a new study analyzing the carbon uptake potential of soil. However ...

Soil nutrients may limit ability of plants to slow climate change

Many scientists assume that the growing level of carbon dioxide in the atmosphere will accelerate plant growth. However, a new study co-written by University of Montana researchers suggests much of this growth will be curtailed ...

Agronomist weighs environmental impacts of corn residue removal
