Study: Can land ecosystems go from being a carbon sink to a carbon source in the future? The study investigates whether climate change-induced temperature changes will bring the carbon uptake and release of terrestrial ecosystems to a tipping point.

Study: A comparatively large amount of carbon from the atmosphere is also bound in the soil under old trees. Thus, old trees make an important contribution to climate protection above and below ground. This must be taken into account in timber harvesting if climate protection in the forest is to gain in value.
Study: The researchers show how that the Nitrogen input in forests has much more impact than the climate change so far. The data came from 100,000 coniferous and deciduous trees in 442 even-aged pure stands from 23 European countries.
The study of the Naturwald Akademie Germany shows how the climatic performance of the forest can be improved in Europe through near-natural, low-impact forestry. In the ideal case, forests can bind twice as much CO2 from the atmosphere each year. For this to happen, the current practice of forest management would have to change throughout Europe.
In our letter to the editor of GCB Bioenergy we show, that burning of fresh stemwood that both increases the atmospheric greenhouse gas concentration and reduces functional natural carbon stocks as well as sinks is not reasonable.
An international study, in which more than 90 scientists participated and in which 48 globally distributed, large forest areas were examined, shows that especially trees of large diameter are important for the forest ecosystem and the storage of carbon dioxide from the atmosphere.
