The forests of the Amazon are an important carbon sink

A recently published study, completed by researchers from the University of Helsinki together with Dr Katerina Machacova, a visiting scholar, demonstrates that boreal forests of the Northern Hemisphere are sources of the greenhouse gas nitrous oxide (N2O). The study provides new information on the significance of trees as sinks and sources of greenhouse gases, proving that forests have relevance not only in the absorption of carbon, but also as a source of other greenhouse gases. The research group observed that the greenhouse gas nitrous oxide is released into the atmosphere not only by the forest soil, but also by pine, birch and spruce, the trees of the northern boreal zone. The group has previously demonstrated (Machacova et al., 2016;Scientific Reports) that the stems and canopies of pine trees in the northern boreal zone are sources of N2O. This recent study indicated that also birches and spruces release the gas into the atmosphere. “Trees may have an impact more significant than previously tho

The forests of the Amazon are an important carbon sink

The world's tropical forests store huge quantities of carbon in their biomass and thus constitute an important carbon sink. However, current estimates of the amount of carbon dioxide stored ...

Coastlines' contribution to climate change might have been underestimated

Permafrost coasts make up about one third of the Earth's total coastline. As a result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the Arctic Ocean. ...

Where Does the Carbon Go When Permafrost Coasts Erode?

Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.
